This document provides a summary of Commercial Off The Shelf (COTS) products and vendor-led development in 3 sentences or less:
COTS implementations can reduce development timelines to 1/3rd and accelerate delivery from 9 months to 5 months. They also allow faster iteration, with refactors taking 3 months down to 1 week. However, COTS solutions must be carefully evaluated to ensure they meet requirements and provide expected benefits like reduced costs, better scalability and vendor support.
