가능한 Contract의 종류:

> We have noted several types of contracts that can work for agile software development:
>
> - <Time and material contracts> using concurrent development with highest priority features implemented first and working, integrated code delivered at each iteration so that the customer may easily manage cost by limiting scope.
> - <Multistage contracts> using a master contract and work orders to release each iteration, with similar emphasis on concurrent development, highest priority features first, and working, integrated code delivered at each iteration.
> - <Target cost contracts>, which charter the frontline workers of both parties to work together to come up with a solution to the problem that meets a target cost, giving them the freedom to limit scope as a primary mechanism to achieve the target cost.
> - <Shared benefit contracts> that assume the parties will modify what they are doing as time goes on to achieve mutual benefit.
>
> There is a common theme here: All of these contracts are mechanisms that avoid fixing scope in detail. --p176-177
