How agile COTS selection methods are (and can be)?

Abstract

Agile methods are proposed nowadays as a way to support software systems procurement. Most of the existing proposals such as eXtreme programming or scrum seem to conceive software procurement as an exercise of software development. However, a great deal of software systems are commercial off-the-shelf (COTS)-based systems, in which the focus changes from bespoke software development to COTS selection and integration. Many proposals for COTS selection have been issued and therefore one may wonder how do they behave from the agile point of view. In this paper, we study the agile principles in the context of COTS selection and we analyze some of the most widespread existing methods. As a result, we identify some practices that would help in making COTS selection processes more agile.
