Frequently Asked Questions

What is a Disparity Study?

Disparity studies are a means of providing a factual basis for determining whether there are equal opportunities for all firms in the procurement process and support the need, if any, for race or gender conscious, remedial procurement programs. The study will engage in a review of the State’s procurement process, availability and utilization and analyze participation in contracts by all vendors, including Minority (“MBE”), Women (“WBE”) (collectively “M/WBE”) to analyze whether there is equal access to public contracts for all business owners.

This Study will cover contracts awarded between FY 2013 and FY 2018 (January 1, 2013 – December 31, 2018). If the actual utilization of firms is less than what is expected based on firms that are ready, willing, and able to perform on State contracts (“Availability”), then a “disparity” exists. The Study will also determine whether the disparity is statistically significant enough to suggest whether any action should be taken or whether factors other than race or gender are likely to have caused the disparity.

What is the Study Process?

A disparity study process is broken out into several major parts, including statistical and econometric analysis, legal and purchasing practices analysis, anecdotal evidence analysis, and findings and recommendations. GSPC is currently collecting data from Sound Transit that will be necessary to determine utilization of firms in the marketplace. Our Chief Statistician, Dr. Rom Haghighi will then analyze the data to determine Sound Transit’s availability and utilization of M/W/DBE firms. Senior Economist, Dr. Gregory N. Price, will then work with available data to determine, through econometric analyses and an analysis of the private sector, whether identified disparities can be attributed to the race and/or gender status of firm owners.

Anecdotal evidence is also crucial to any recommendations we may make to Sound Transit as a result of our study findings. Our anecdotal evidence includes the following:

  • Survey of business owners across all work categories.
  • Firms throughout Sound Transit marketplace will be contacted inviting them to complete the survey.
  • In-depth anecdotal interviews with businesses in the area, selected randomly from a list of available vendors.
  • Focus groups of randomly selected business owners to share their experiences in doing business in the Sound region and with Sound Transit
  • Email comments, Informational meetings and public hearings which will all be open to the public.

Other relevant study processes include an analysis of Washington’s legal environment, both locally and federally and a purchasing practices analysis. The study team will conduct interviews with City procurement staff regarding their procurement process and the current procurement policies to review whether any barriers to participation exist in the procurement process.

Finally, GSPC will compile a final report taking into account all of the findings from the research above, and will provide recommendations to Sound Transit regarding their DBE program and procurement processes.
