Who is typically responsible for the creation and update of a test plan for a project?

The test manager is typically responsible for the creation and update of a test plan for a project. This role involves overseeing the entire testing process and ensuring that the testing activities align with project objectives and goals. The test manager coordinates with different stakeholders to gather necessary information, define testing strategies, and set the scope for what needs to be tested.

Creating a test plan requires a deep understanding of the project requirements, risks, and resources available, which is within the purview of a test manager. It involves not only outlining the testing objectives but also detailing the approach to be taken, the resources required, the schedule, and the deliverables. The test manager must also be prepared to update the test plan as the project evolves, incorporating any changes in scope, timelines, or resources as necessary.

Other roles, such as the project manager, tester, or product owner, certainly play important parts in the testing process, but their responsibilities are generally more focused on broader project management, executing tests, and defining product requirements, respectively. The creation and maintenance of the test plan are critical functions that fall within the specialized expertise of the test manager, positioning them to ensure comprehensive and effective test coverage throughout the project lifecycle.
