Roles organize the responsibility for performing tasks and developing work products into logical groups. Each role can
be assigned to one or more people, and each person can fill one or more roles. When staffing the Tester role, you need to consider both the skills required for the
role and the different approaches you can take to assigning staff to the role.
We recommend reading Kaner, Bach & Pettichord's Lessons Learned in Software Testing [KAN01], which contains an excellent collection of important
concerns for test teams. Of special interest to the Tester role are the chapters on The Role of the test group
and Thinking like a tester and Bug advocacy.
