• Roles and Responsibilities Test plan explains the roles and responsibilities of individuals involved in testing process. It includes activities to be done by stakeholders of the project. Roles and responsibilities define who is responsible for which activity at each stage of testing. It is good practice to generate responsibility matrix with people involved in doing different activities and representing different positions in columns while activity list is along each row. Table 14.4 represents a typical distribution of roles and responsibilities for people concerned with testing. It may change from project to project/organisation to organisation/customer to customer.
