Who is typically responsible for writing the test plan for a project?

The test manager is typically responsible for writing the test plan for a project. This role involves creating a comprehensive document outlining the testing strategy, objectives, resources, schedule, and scope of testing activities. The test manager ensures that all aspects of testing are considered, including risk assessment, testing methods, and criteria for success. This responsibility is crucial as it sets the foundation for the testing process and aligns the testing efforts with project goals.

While the project manager might be involved in overall project planning, they focus on aspects like resource allocation, budgeting, and timelines, rather than the specifics of testing. The product owner may outline requirements and priorities from a business perspective but does not usually write the test plan. Testers are primarily responsible for executing tests based on the established plan and do not take on the task of creating the test plan itself. Therefore, the role of the test manager is essential in ensuring that the testing process is structured and that all relevant factors are adequately addressed.
