 ### Modular contracting
 
-By combining user-centered design, agile, product ownership, DevOps, and building with loosely coupled parts, it’s possible to break up a large, risky contract into a handful of smaller contracts. A contract should be small enough that the agency will have no compunction about giving no further work to a non-performing vendor, replacing them with a new vendor. (See "[Procure services, not software]({{ "/derisking/state-field-guide/#procure-services-not-software" | url }}) for how this is done.) The rest of the vendors will continue working, so the total loss of velocity will be minimal. A new vendor should have no difficulty taking over for the old one, since the old one was delivering completed, documented, tested software every two weeks. Another benefit is that small contracts may come in under your state’s simplified procurement threshold, meaning that agencies can write a request for proposals, publish it, and award a contract, all within 90 days or so.

 There are vendor teams that specialize in working as we’ve described here. As a rule of thumb, an agile development team of 5–9 people costs between \$1–2M/year, depending on their geographic location.
