A sample answer to question 1

How do you develop a test strategy and test plan for a large programme, and how do they differ?

A test strategy is the high-level, relatively stable statement of how the organisation or programme approaches testing: objectives, risk approach, levels and types of testing, automation principles, environments, tools, governance and metrics. The test plan applies that to a specific project or release, detailing scope, schedule, resources, environments, test data, entry and exit criteria, dependencies and risks. To develop them, I begin with the business objectives and a risk assessment with product, architecture and operations, then agree what quality means for this programme. I align with the delivery method, whether Agile, waterfall or hybrid, and with standards such as ISO/IEC/IEEE 29119 and ISTQB practice. I keep documents concise, review them with stakeholders and treat them as living, updating them as risks change. The goal is not a heavyweight document but a shared understanding of how we will give the business confidence in the release.

Common mistake to avoid: Producing a template nobody reads; Ignoring delivery method
