15.1 INTRODUCTION

In this chapter, we will look at some of the project management aspects of testing. The Project Management Institute [PMI-2004] defines a project formally as a temporary endeavor to create a unique product or service. This means that every project has a definite beginning and a definite end and that the product or service is different in some distinguishing way from all similar products or services.

Testing is integrated into the endeavor of creating a given product or service; each phase and each type of testing has different characteristics and what is tested ...
