How we work · Our approach

We find what causes a disparity, and what to do about it.

Anyone can divide availability by utilization and report a number. Boston has the number, and five years of reform behind it. The City needs to know what moved, what did not, where in its own process each gap forms, and why.

The surface read

The disparity index: a group's share of contract dollars (utilization) divided by its share of firms in the market (availability), scaled to 100, with values under 80 marking substantial underutilization. Boston already has a rigorous version of this number. BBC Research & Consulting's 2020 disparity study, final report February 2021, measured availability with a custom census of roughly 800 phone surveys and found combined MWBE availability of 16.9% against utilization of 11.0% for FY2015 through FY2019, an index of 65. The group detail is sharper: Black American-owned firms at 12, non-Hispanic white woman-owned at 76, Hispanic American-owned at 70, and Asian American-owned at 141, above parity. HSG has extended the surface read forward from the City's open data: the certified-MWBE share of discretionary spending rose from 5.2% in FY19 to 12.3% in FY25. Those computed figures count City- or state-certified firms only, so they are a floor on true MWBE participation, not a like-for-like update of BBC's certified-or-not measure.

flags underutilization

It shows the size and direction of the gap between presence and participation, and it shows where to look first. Boston's baseline is stronger than most jurisdictions can claim, because BBC's availability rests on a primary-data custom census rather than a raw firm count, and the industry texture is already visible: an MWBE index of 34 in construction against 67 in other professional services, with Black American-owned firms showing substantial disparities across all work types. The post-study trend adds a second read: real, measurable movement in certified-MWBE spend share, from 5.2% to 12.3%, that still sits below BBC's 16.9% availability benchmark and well below the 25% goal the 2021 Executive Order set. The gain is concentrated in MBE spend, while WBE share has stayed nearly flat at roughly 2.4 to 3.0% for eight fiscal years. Together the index and the trend are a credible, transparent first read of where Boston stands.

What it cannot show. It cannot show causation, and a gap does not mean the City did anything wrong. It cannot say whether the gap survives controls for legitimate competitive factors like firm age, size, experience, and capital, so it cannot tell capability apart from exclusion. It cannot locate where in the procurement process firms fall out (registration, certification, awareness, bidding, selection, payment, or subcontracting). The certified-spend trend has limits of its own: it counts certified firms only, so it cannot separate new market entrants from incumbent vendors who newly certified, it cannot say why the Sheltered Market Program and the Executive Order goals moved MBE participation while WBE share stayed flat, and it misses subcontract dollars wherever they are not tracked. It carries no statistical-significance test and no anecdotal record, and a headline number masks group-by-industry texture that BBC's own results show can run from 12 to 141 inside one average.

Computing the ratio takes minutes, and Boston has already paid for the ratio done properly once. A study that re-runs the same surface arithmetic on fresh data and stops there tells the City what it mostly already knows: a gap existed in 2020, some measures were adopted, and the certified numbers moved. That is the standard update the large, established disparity-study firms typically deliver, and it is also the read a hostile expert can take apart in deposition, because it is a correlation with no theory of cause, no controls for capability, and no location in the procurement process. The update Boston actually needs is causal: what moved after the 2021 Executive Order and the Sheltered Market Program, what did not move, and why. We treat the ratio as the first step and build the causal and locational analysis behind it, so the City receives recommendations it can act on and defend.

Where we go

The ratio is the start, not the answer

Start with the simple measure. BBC's 2020 study put combined MWBE availability at 16.9% against utilization of 11.0% for FY2015 through FY2019, a disparity index of 65, with construction at 34 and Black American-owned firms at 12. The City responded: the February 2021 Executive Order set citywide goals of 25% MWBE (15% WBE, 10% MBE) of discretionary spending and required departmental equitable procurement plans, and in August 2022 the City adopted the Sheltered Market Program under M.G.L. c. 30B Section 18. HSG has computed the trend since from the City's own open data: certified-MWBE share of discretionary spending rose from 5.2% in FY19 to 12.3% in FY25, a floor on true participation because it counts certified firms only. We produced those figures from public data before any engagement, and they are on the portal with every number traceable to its source.

A ratio and a trend line tell you a gap existed and that it narrowed. They do not tell you what produced either fact, because a divided figure carries no information about cause. The deeper work traces the procurement funnel stage by stage, from vendor registration and certification to awareness of opportunities to bidding to the responsiveness and responsibility check to award to prompt payment to subcontract participation. We add a private-sector regression, a qualified-willing-and-able availability survey reconciled to BBC's 2020 baseline, the 16-barrier framework, and structured verified interviews. Where firms drop off in the funnel points to the kind of problem at work, and a supply problem, a selection problem, a payment problem, and a network problem each call for a different fix. Why MBE spend rose while WBE share stayed flat for eight years is exactly this kind of question, and we do not prejudge its answer.

Pinpointing the cause is what lets a recommendation be specific. Once the analysis shows which stage of the funnel the drop-off happens at, and which explanation holds up, the fix follows from it. A drop-off at registration or certification points to outreach and a simpler onboarding path across the City and Commonwealth SDO tracks. A drop-off at the bid stage points to how opportunities are advertised and how qualifications are written. A drop-off after award, in slow payment, points to the City's payment practices. Each fix attaches to a mechanism the City can change, and Boston already holds the levers: the departmental equitable procurement plans the 2021 Executive Order requires, the Sheltered Market Program, and its own certification pipeline. We build the recommendations race-neutral first, in the order the law and 49 C.F.R. 26.51 expect. Most of what closes these gaps is open to every firm and does not turn on the race or gender of its owner: unbundling large contracts, fixing payment timelines, broadening bid lists, and helping firms build the relationships that informal networks otherwise ration. The goal is more firms from every segment of the community competing for and winning City work.

Boston already knows the number. The update's job is to explain it, group by group and stage by stage.

The discipline that makes a finding credible

What a gap can and cannot tell you

A low disparity index does not prove the City did anything wrong, and we do not start from that assumption. A raw difference between availability and utilization is a correlation, and a correlation can have several sources, only some of which point back at the City. The cause may be something the City controls, such as how bid lists are built or how prequalification and bonding thresholds are set. It may be marketplace-wide, reaching across public and private buyers and rooted in access to capital or in the informal networks that decide who gets the first referral. It may be a legitimate, non-discriminatory difference in the firms themselves, in size, capacity, or the lines of work they are positioned to bid. Our job is to test those explanations against the evidence. We control for capability and qualifications, we examine whether the City's own criteria are appropriate and least restrictive, and we build the record to the strong-basis-in-evidence standard the Supreme Court set in Croson, under the heightened scrutiny the SFFA decision confirmed. The First Circuit has no modern disparity-study precedent as fully developed as some other circuits have produced, which makes a conservative, attack-tested record more valuable to Boston, not less. A finding that survives that scrutiny is one the City can stand behind. A benign explanation is just as useful to surface, because it shows where effort is not needed. We report whichever answer the evidence supports.

The ladder of analysis

From a gap to its cause

Each step answers a specific causal question and addresses a rival explanation, so the study can say not only that a gap exists but why, and where the City can act. The tag on each step marks whether the cause it isolates is something the City controls, a marketplace-wide condition, or a legitimate difference in capability.

City-controllableMarketplace-wideLegitimate capabilityMixed
01
Availability done properly (qualified-willing-able custom census)
Of the firms that are actually ready, willing, and able to perform City of Boston work, what share is minority-owned or women-owned, how has that share moved since BBC's FY2015-FY2019 custom census, and does the gap shrink, hold, or grow once availability is measured correctly?
Mixed

PhD-led stratified custom-census survey of firms in a spend-derived market area, NAICS-weighted to City and Boston Public Schools expenditure, telephone plus email, to a 95% confidence interval and plus-or-minus 5% per industry subsector. Anchor willingness to active public-work registration and observed bid behavior. Because a firm must register to bid, the City's supplier registration rolls and the City and Commonwealth SDO certification directories define a bounded, followable universe of firms that have signaled willingness to do public work, the tractable government-contracting market the survey then measures readiness within, knowable in a way the open private economy is not. Following the Houston study and NCHRP 644, and consistent with Croson's qualified-willing-and-able standard, do not capacity-discount the denominator, since current capacity is itself partly a product of past conditions; the only ability filter is genuine market-area presence and line-of-business match. Reconcile the new census against the 2020 BBC availability database and appendices so change over time is measured on a consistent basis, and replace equal-weight ABS firm counts with this weighted denominator before recomputing any index.

Data it needs

What it rules in or out

Rules out the leading attack that the gap is an artifact of an inflated headcount denominator (counting firms that never bid or are out of line-of-business). If the gap persists against a willing-and-able, spend-weighted denominator, an availability-measurement explanation is ruled out.

02
Bid and offer (lost-contract) analysis: supply gap versus selection gap
When minority-owned and women-owned firms do bid, do they win at the rate their bidding share predicts, or do they fall out at selection? Is the gap a supply problem (they are not at the table) or a selection problem (they are at the table and lose)?
Mixed

Build a bid-level dataset of who requested documents, who submitted, and who won, by solicitation. Compute a bid-to-award ratio by ownership and compare it to the availability-to-award ratio. A gap that closes at the bid stage points to a supply or awareness problem upstream; a gap that opens at the bid stage points to a selection problem at evaluation. Pair with offer and lost-contract records where they exist so willingness rests on bid behavior rather than registration alone.

Data it needs
plan-holder and document-request logs per solicitationbid tabulations and submitted-offer records (prime and, where captured, sub)award decisions with evaluation scores or low-bid determinationsownership classification matched to each biddersolicitation files for the City and Boston Public Schools across the study window
What it rules in or out

Separates the supply explanation (firms are not bidding) from the selection explanation (firms bid and are not selected). This decides which half of the funnel the rest of the analysis must concentrate on and rules one of the two out as the dominant channel.

03
Procurement-funnel stage-drop-off analysis
At which specific stage of the procurement process (registration, certification, awareness of opportunities, bidding, responsiveness and responsibility determination, award, prompt payment, subcontract participation) do minority-owned and women-owned firms fall out, and by how much at each stage?
Mixed

Construct a stage-by-stage conversion funnel and compute the retention rate by ownership at each transition: registered share, certified share, opportunity-aware share, bidder share, responsive-and-responsible share, awardee share, paid-on-time share, and subcontract-participation share. Locate the stage with the largest ownership-specific drop. Each stage implicates a different cause and a different fix: a registration or awareness drop is a supply and outreach problem, a bid-to-responsive drop is a criteria problem (route to S5), a responsive-to-award drop is a selection or network problem (route to S6), and a payment drop is a cash-flow problem.

Data it needs
registration and certification rolls (S1)opportunity-notice distribution and outreach reach databid and plan-holder logs (S2)responsiveness and responsibility determinations with reasonsaward recordsaccounts-payable invoice and payment-date records (days-to-pay)subcontractor participation and good-faith-effort filings
What it rules in or out

Locates causality in process space. It rules out a single global story by forcing the gap to a stage. A supply-stage drop rules out a selection bias claim; a payment-stage drop rules out an availability claim; a sub-stage drop points to prime behavior rather than City selection.

04
Contract-level utilization regression: net-of-capability residual
After controlling for legitimate, non-discriminatory competitive factors, how much of the City-side gap remains unexplained?
Mixed

Estimate a contract-level (and firm-level) regression of award and dollars received on ownership while controlling for firm age, firm size (employees and receipts), prior relevant experience, owner education, capital and bonding capacity, contract scope and dollar size, procurement method, and industry cluster. The coefficient on ownership, net of those controls, is the residual gap. Report it with confidence intervals. A residual at or near zero means capability differences explain the raw gap; a significant residual means a portion is not explained by capability.

Data it needs
contract- and payment-level transaction records for the City and Boston Public Schools (the internal counterpart of the Analyze Boston contract-award and discretionary-spending extracts, not a public summary)firm attributes from the custom census (S1): age, size, experience, owner education, capital and bonding capacitycontract attributes: scope, dollar size, NAICS, procurement method, bundling flagownership classification per firm
What it rules in or out

Rules in or out the legitimate-capability explanation. A raw index of 65, or 12 for Black American-owned firms, can reflect that diverse firms are younger, smaller, or less capitalized on average. If the gap vanishes under controls, the cause is capability and the remedy is capability-building, not preference. A surviving residual is the evidentiary core of a marketplace-discrimination finding.

05
Appropriateness-of-requirements and evaluation-criteria audit with disparate-impact screen
Do the City's own procurement screens (experience floors, bonding, insurance, prequalification, reference counts, minimum firm size, contract bundling) exclude qualified minority-owned and women-owned firms beyond what the work actually requires?
City-controllable

Inventory and code every City and Boston Public Schools solicitation in the study period for each screen. For each criterion, estimate the share of the available minority-owned and women-owned pool versus the non-minority pool that could satisfy it, using the census firm-age, capital, bonding-capacity, and experience data, and apply a disparate-impact screen by ownership using the EEOC four-fifths convention as an analytic analogy (distinct from the disparity-index threshold of 80 on the 100 scale, which shares the four-fifths ratio by coincidence), flagged for significance. Run a fit-to-scope test (is a five-year or three-prior-contract floor necessary for routine work; is bonding calibrated to real payment risk; is a contract bundled past small-firm reach). Conclude with a least-restrictive-means review producing a keep, right-size, or replace recommendation per criterion, benchmarked to 49 C.F.R. 26.51 and the competition M.G.L. c. 30B is designed to secure. Apply the same audit to the City's own disparity-study solicitation (Event ID EV00017483) as a proof of concept. Augment the manual coding with an AI-assisted read of the full procurement-rules corpus that surfaces internal rule conflicts and candidate disparate-impact provisions for a named investigator and counsel to verify; the AI accelerates and broadens the review but makes no finding, and a responsible-AI advisor governs the bias-testing and documentation of that step.

Data it needs
full solicitation corpus for the City and Boston Public Schools across the study windowcoded criteria per solicitation (experience years, prior-contract count, bonding type and amount, insurance limits, prequalification, reference count, minimum size, contract dollar size and bundling)census data on firm bonding capacity, capital, age, and experience by ownership (S1)statements of work and contract risk profiles for the fit-to-scope test
What it rules in or out

Rules in or out the explanation that the City's neutral-looking requirements are themselves the barrier. A criterion that few minority-owned firms can meet, and that exceeds what the work requires, is a City-controllable cause distinct from any bidder behavior, and it grounds race-neutral remedies before any race-conscious measure is considered.

06
Network-effects and social-capital analysis (Loury contact versus contract)
How much of the residual gap runs through informal networks and relationships (Loury's discrimination in contact) rather than formal rules (discrimination in contract): repeat-player concentration, referral-based and sole-source award, and prime-sub pairing?
Mixed

Operationalize Loury's contact-versus-contract distinction. Measure repeat-player concentration (share of dollars to firms with prior awards and Herfindahl-type concentration by ownership), the share of dollars flowing through sole-source, informal small-purchase, and referral or relationship channels versus open competition, and prime-sub pairing patterns (do the same primes pair with the same subs, and are minority-owned and women-owned firms locked out of those pairings or bound by exclusivity). Pair with the structured anecdotal protocol (S9) on old-boy-network and exclusivity themes. Compare ownership-specific gaps in informal channels against open-competition channels.

Data it needs
award histories with repeat-vendor flags over multiple yearsprocurement-method breakdown (open bid versus sole-source versus small-purchase versus cooperative)prime-subcontractor pairing records and any exclusivity agreementsreferral and informal-quote records where capturedanecdotal corroboration on network access (S9)
What it rules in or out

Rules in the social-capital channel as a cause and distinguishes it from formal-rule causes (S5) and from capability (S3). It supplies the theory of discrimination that a bare ratio lacks: if gaps concentrate in informal, relationship-driven channels and shrink in open competition, the durable barrier is network access, which both formal-criteria reform and capability-building miss.

07
Private-sector marketplace but-for regression
Is the disadvantage specific to City of Boston procurement, or is it a marketplace-wide condition present across the regional private economy independent of anything the City does?
Marketplace-wide

Mirror the Houston Chapter 6 design. Estimate private-sector earnings and formation disparities for the Boston region: linear regressions on individual wages and on business-owner earnings, and logistic regressions on the probability of self-employment and business-formation rates, using PUMS microdata, controlling for race and gender, capital availability (homeownership, home value, mortgage status, unearned income), education, age and age-squared, marital status, English proficiency, disability, and market-area residence. Layer Census ABS and SBO private-sector revenue disparities by NAICS. A significant gap in the private-sector model establishes passive, marketplace-wide discrimination that the City did not create.

Data it needs
ACS PUMS 5-year microdata for the Boston-Cambridge-Newton MA-NH metro (wages, self-employment, business-owner earnings, demographics, capital proxies)Census ABS 2022 and SBO private-sector receipts by ownership and NAICSmetro business-formation rates by group
What it rules in or out

Distinguishes City-specific causation from marketplace-wide disadvantage. If the gap is large in the private economy too, part of the cause is passive societal discrimination outside the City's control, which under Croson can support the compelling interest while pointing remedies toward marketplace-facing tools. If the private-sector gap is small but the City gap is large, the cause is more local and City-controllable.

08
Access-to-credit and capital-formation channel
Are capital and financing constraints a distinct upstream cause limiting firm formation, scale, and bonding capacity for minority-owned and women-owned firms?
Marketplace-wide

Add a dedicated access-to-credit sub-analysis. Estimate differences in loan denial rates, financing terms, startup capital, and reliance on personal and home equity by ownership, using HMDA, the Survey of Business Owners and ABS company-characteristics modules, Small Business Credit Survey data, and the homeownership and home-value capital proxies from the PUMS model (S7). Anchor to the Fairlie and Robb capital literature. Link capital constraints to firm size, bonding capacity, and the formation gap so the capital channel is explicit rather than folded into a generic capability control.

Data it needs
HMDA and Small Business Credit Survey data for the metroABS company-characteristics and SBO financing modules by ownershipPUMS capital proxies (homeownership, home value, mortgage status) from S7census firm-level bonding and capital-capacity responses (S1)
What it rules in or out

Rules in capital access as a specific, separable cause rather than an undifferentiated capability gap. It clarifies whether the right remedy is bonding assistance and capital access (a marketplace-facing, often race-neutral tool) versus selection or network reform, and it strengthens the marketplace-discrimination finding by tracing one of its mechanisms.

09
Verified structured anecdotal corroboration
Do the lived experiences of firm owners and trade organizations corroborate the statistical findings and identify the specific stages and mechanisms the numbers flag?
Mixed

Run separately instrumented, structured interviews using distinct guides for businesses and for professional and trade organizations, recruited broadly (email, mail, personal contact, public hearings) to reduce self-selection. Code each account to the procurement-funnel stage (S4) and the barrier framework. Verify each owner account against the procurement record where possible (the bid was submitted, the payment was late, the criterion applied), and retain all transcripts. Report corroboration by theme: informal networks, bonding and insurance, slow payment, prime-sub exclusivity, and repeated demands to prove qualifications.

Data it needs
structured interview guides (business and organization versions)broad recruitment outreach recordsowner and organization interviews and public-hearing testimonythe procurement record for each verifiable claim (bid logs, payment dates, criteria)retained transcripts and a coding scheme keyed to funnel stage and barrier
What it rules in or out

Courts applying Croson require statistical disparity be corroborated by significant anecdotal evidence, and the standard attack is that anecdotes are unverified or out of context. Verified, retained, stage-coded accounts rule out the noise explanation and tell whether the experiential signature matches the statistical location, while broad recruitment rules out a self-selected-complaint bias.

10
Statistical-significance testing and group-by-category specificity
For which specific groups and which specific industry categories is the gap both substantial and statistically significant, and where is it not, so findings and remedies attach only where the evidence holds?
Mixed

Apply a dual test to every group-by-cluster-by-category cell: disparity index at or below 80 on the 100 scale (substantial) and a t-test for statistical significance, with confidence intervals reported. Build the findings as a group-by-category matrix marking each cell disparity or no disparity and flagged for significance, rather than a single headline index. Report honest counter-results, including any group overutilized in a category, the way BBC's own results showed Asian American-owned firms above parity overall. Pre-register the methodology and apply the test uniformly so the study can return a null.

Data it needs
recomputed availability (S1) and utilization (transaction-level) per group per cluster per categorycell-level sample sizes for significance testingthe residual coefficients and confidence intervals from S3a pre-registered analysis plan and the dual-test thresholds
What it rules in or out

Rules out the noise explanation (a gap from small numbers or chance) and the over-inclusion problem (treating all minorities as one undifferentiated group). Croson condemned the laundry-list approach, and courts applying it have upheld remedies only for the groups the evidence supported. Significance plus group-by-category specificity is the binding constraint that decides which findings from every prior step are real and remediable.

What it takes

The data this analysis requires

The deeper analysis is only as good as its inputs. This is the full data picture, what we collect ourselves and what the City and Boston Public Schools would provide, so the work is concrete rather than aspirational.

The payoff

From cause to action

Pinpointing the cause is what makes a recommendation targeted instead of blunt. Each cause the analysis can isolate maps to a specific fix and a specific City lever. We lead with race-neutral, opportunity-focused measures and reserve anything race-conscious for the narrow, significant, group-specific gaps that neutral fixes cannot close.

If the cause is

Drop-off concentrated at the vendor-registration and certification stage (ready firms never enter the City's Supplier Portal or either certification pipeline, so the supply of bid-eligible diverse firms is thin before any solicitation runs)

We recommend

Run targeted registration drives with the regional minority and women business associations, pre-fill and simplify Supplier Portal onboarding, deepen the cross-recognition between City certification and Commonwealth SDO certification so one application clears both paths, and shorten certification turnaround so a willing firm can register and become bid-eligible in days rather than weeks

City lever

Certification streamlining between the City and the Commonwealth SDO, plus vendor-registration outreach

Race-neutral
If the cause is

Drop-off at the awareness stage (registered diverse firms are in the pool but do not learn of relevant solicitations in time to respond, and bidder lists skew to incumbents)

We recommend

Publish a rolling 12-to-18-month procurement forecast, push targeted notices to certified firms by NAICS, hold pre-bid sessions timed early enough to prepare a bid, and make forecasting and outreach obligations explicit in each department's equitable procurement plan

City lever

Outreach and advance forecasting through the departmental equitable procurement plans the 2021 Executive Order requires

Race-neutral
If the cause is

Experience floors and prior-similar-project minimums in solicitations exceed what the scope actually requires, screening out capable firms at responsibility review before price is read

We recommend

Audit and right-size past-performance language to the work, accept comparable, aggregated, or subcontractor experience and key-personnel experience in place of firm-level history, and document the justification for any threshold retained

City lever

Solicitation drafting and qualification-setting standards in the City's M.G.L. c. 30B procurements

Race-neutral
If the cause is

Drop-off concentrated at the bidding stage for construction, where bonding capacity caps who can bid as a prime rather than firm capability

We recommend

Stand up a City bonding-assistance track (fee buy-downs that remove surety cost from bid evaluation, threshold reductions on smaller jobs, and a referral partnership with the SBA Surety Bond Guarantee Program), available to all small firms that cannot bond the full contract

City lever

Bonding assistance and solicitation bond-threshold scaling

Race-neutral
If the cause is

Large bundled solicitations consolidate scopes that could be procured separately, confining smaller firms to subcontract roles and foreclosing the prime path

We recommend

Unbundle where the consolidation is not operationally justified, break large buys into right-sized lots, and require a written bundling justification before aggregating requirements. Documented practice supports this: breaking large contracts into smaller, right-sized lots has been shown to raise small and minority- and women-owned participation with no quotas or set-asides

City lever

Unbundling and contract-structuring policy

Race-neutral
If the cause is

Awards concentrated among repeat primes reached through informal referral and relationship-based selection (Loury's discrimination in contact, the social-capital channel rather than a formal rule)

We recommend

Move informal opportunities onto the open record by advertising small-purchase and quote-based buys, rotating quote solicitations across the certified pool, and instituting a structured matchmaking program that introduces unaffiliated firms to primes and buyers

City lever

Anti-exclusivity quote rotation, open advertising of informal buys, and matchmaking

Race-neutral
If the cause is

Slow or non-prompt payment strains cash flow so that diverse firms decline larger awards or cannot carry the gap between performance and payment

We recommend

Enforce and tighten prompt-payment timelines, add progress-payment acceleration and mobilization advances on larger contracts, and require primes to flow prompt payment down to subcontractors with monitored compliance

City lever

Prompt-payment policy and progress-payment terms

Race-neutral
If the cause is

Subcontract participation lags because good-faith-effort requirements are unmonitored, allowing bid shopping and after-award substitution of listed diverse subs

We recommend

Require subcontractor listing at bid, verify good-faith effort, monitor actual sub payments against the plan, and bar post-award substitution without City approval

City lever

Subcontracting good-faith-effort enforcement and payment monitoring

Race-neutral
If the cause is

Restrictive or proprietary specifications (brand-name calls, narrow product specs, or credential requirements) limit the field for reasons unrelated to performance

We recommend

Convert proprietary specs to performance-based or or-equal language, scrutinize each restrictive criterion for necessity, and require justification for any single-source specification

City lever

Solicitation drafting and procurement-criteria appropriateness audit

Race-neutral
If the cause is

The binding constraint is upstream and marketplace-wide access to capital (firms are undercapitalized at formation and cannot finance working capital), a condition that reaches well beyond City contracting

We recommend

Partner with regional CDFIs and community banks on working-capital and mobilization loan funds for small contractors, and pair the financing referral with the prompt-payment and progress-payment fixes that reduce the capital a contract demands; treat the capital gap as a shared-marketplace condition the City mitigates rather than one it caused

City lever

Capital-access partnerships plus prompt-payment and progress-payment terms

Race-neutral
If the cause is

Firms cluster at the bottom contract-size band and never graduate to larger work because they cannot accumulate the past performance and bonding history larger awards require (a self-perpetuating capacity ceiling, not current incapacity)

We recommend

Run a mentor-protege and graduated capacity-building track that pairs emerging firms with established primes, builds verifiable past performance on staged scopes, and steps firms up in contract size as they demonstrate readiness

City lever

Mentor-protege and graduation pathway in the race-neutral SLBE and SBE tracks

Race-neutral
If the cause is

A measured gap traces to a legitimate non-discriminatory difference (for example, diverse firms in a category are concentrated in NAICS the City rarely buys, or differ systematically in firm size matched to the work), and the gap does not survive controls for those factors

We recommend

Make no remedy on this finding, document the non-discriminatory explanation, and redirect effort to categories where a controlled gap remains; revisit if the marketplace composition shifts

City lever

None required; route engagement effort to general supplier-diversity outreach where the data warrants

Race-neutral
If the cause is

For a given group and category the preliminary index falls below 80 but the gap does not survive the dual test (it is not statistically significant once availability is restricted to qualified, willing, and able firms and controls are applied)

We recommend

Record no disparity finding for that group-and-category cell, do not set a goal there, and route the firms into the race-neutral SLBE and SBE tracks rather than a group-specific measure

City lever

Race-neutral SLBE/SBE track; no goal-setting for that cell

Race-neutral
If the cause is

After race-neutral measures are determined insufficient to close it, a statistically significant, group-and-category-specific disparity persists and is corroborated by verified anecdotal evidence of differential treatment that neutral measures cannot close

We recommend

Set a narrowly tailored, group-and-category-specific participation goal scaled to the proven shortfall, calibrate Sheltered Market Program designations under M.G.L. c. 30B Section 18 to the same evidence, sunset both on a fixed review cycle, and retire them once parity holds; apply them only to the groups and categories the evidence supports

City lever

Group-specific goal-setting and Sheltered Market designation, time-limited and evidence-bounded

Race-conscious, if warranted

How we keep it fair and defensible

The commitments that keep the analysis honest

A nuanced study introduces ways to overreach. These are the guardrails we build in from the start, several of them required by Croson and the strict-scrutiny standard that applies in Massachusetts as it does everywhere, so the work is fair to every firm and able to withstand the most skeptical review.

A defined study period
We fix a multi-year study window and justify it up front, because availability, utilization, and the regression panel all depend on it. For Boston the natural anchor is the years since BBC's FY2015 through FY2019 window, so the update measures what changed after the 2020 study rather than re-measuring the same years.
Each group analyzed on its own
We report Black-, Hispanic-, Asian-, Native-American-, and women-owned firms separately, not as one minority aggregate. BBC's own results show why: an Asian American-owned index of 141 and a Black American-owned index of 12 sit inside the same 65 average. Courts applying Croson have upheld remedies for some groups and struck them for others on exactly this point, so group-specific evidence is a requirement.
A separate standard for gender
Gender classifications draw intermediate scrutiny rather than strict scrutiny, and courts have struck women's goals built on thin evidence. Boston gives this guardrail urgency: WBE share of certified spend has stayed nearly flat at roughly 2.4 to 3.0% for eight fiscal years while MBE share rose. We build a distinct women-owned record and hold it to its own bar.
A small-cell rule
When a group-by-category cell has too few observations for a meaningful test, we suppress it or report a confidence interval only, rather than present a number the sample cannot support.
The employer and nonemployer distinction
Most firms in the market are nonemployer (sole proprietor) firms, while public contracts are performed mostly by employer firms. We reconcile the two so the availability denominator is neither inflated nor understated.
Separating the diversity signal from size, and the certified floor from the whole
The City certifies small and local businesses (SLBE, SBE) alongside minority- and women-owned firms, and its spend flags count certified firms only. We separate the race and gender signal from the small-business signal, and we report certified-only figures as a floor on true participation rather than the whole of it, because BBC's baseline counted firms certified or not.
A proxy now, a spend-derived market in the study
The portal's preliminary availability figures use Census ABS data for the Boston metro and BBC's five-county market as public-data proxies. The full study re-derives the relevant geographic market from where the City and BPS actually spend, which can change every index.
Race-neutral measures first, then a look-back
The law expects race-neutral measures to be tried and shown insufficient before any race-conscious goal. Boston is mid-experiment: the 2021 Executive Order goals, the Sheltered Market Program, and five years of certified-spend data are exactly the look-back evidence this guardrail calls for, and the update reads that record honestly, including where a measure did not move its target.
A path for thin data
Where subcontract or payment records are incomplete, we state the fallback for each affected analysis, and we treat the data gap itself as a finding the City can act on.
The team behind the design
This is PhD-grade work. House Strategies Group runs the data, analytics, and project management, and an academic bench supplies the survey, econometric, and legal expertise each step requires.
Why this is the harder, better study
A standard disparity study delivers the ratio and the legal scaffolding around it, and BBC's 2020 study is a competent, credible version of that product, built on 47,000-plus contracts and a custom availability census. We build on it rather than re-litigate it. The surface ratio is the opening move of any credible study, and BBC's baseline plus five years of post-reform data give Boston an unusually rich starting position. What the update adds is the causal analysis, the funnel diagnosis, and the targeted recommendations that follow from knowing where and why each gap forms, and why some measures moved their targets while others did not. The City gets the defensible refreshed numbers every study owes it, and the part that tells it what to do next.
