There is a new rating system in town, and it is for judging which federal contracting officers are most and least “annoying” with whom to work.

      Consulting firm GovTribe debuted its new “Purse String Index,” a fee-based service that ranks thousands of U.S. contracting officers by department. The ratings for the officers are based on factors including how many contract awards they make, average days to award, total days to award, average contract value, sum of amendments, average number of amendments, total number of due date changes and average number of due date changes.

      The index measures, in part, an “annoyance factor,” based on how often the officer modifies a solicitation after posting and how often he or she changes deadlines.

      “We think it’s pretty reasonable to penalize contracting officers for due date changes because that does affect contractors’ bottom line,” GovTribe co-founder Marc Vogtman told NextGov.

      GovTribe has a proprietary algorithm that generates a score for each officer, from zero to 5.

      For the Homeland Security Department, the highest rated officers were Nicholas Martinelli, with a score of 4.35; London Venzon, 3.19; James Lassiter, 3.04; Marcelle Loveday, 2.95; Sheila Midgette, 2.94; Carolyn Ward, 2.88; Samantha Gray, 2.80; Monica King, 2.78; and David Zhang, 2.74.
