The preliminary investigation of a software project has been completed. Two different project

teams have estimated the costs associated with

the development and maintenance of a new system. One team based their estimates on the

assumption that the waterfall system development process would be used for the project; the

other team plans to follow the agile approach.

A third option is to purchase off-the-shelf software that provides nearly all the benefits of a

custom-built solution. Review the estimates

below, and choose the best approach for the

project: waterfall development, agile development, or off-the-shelf software implementation.

Provide a solid rational for your choice. Identify

any assumptions you must make in reaching

your decision.
