Inspection

I define an inspection as a formal review of a work product. First, I choose an independent moderator to lead the process. Then, I select inspectors from peers, business stakeholders, users, and experts. Next, I ask each inspector to prepare thoroughly. For example, I give them detailed checklists and the work product in advance. Consequently, they can find defects and inconsistencies before the meeting.

I run inspections as meetings. During the meeting, the moderator controls the agenda. Meanwhile, the author attends as a listener. Furthermore, the author explains unclear parts when asked. In addition, the inspectors present findings and discuss the impact. Moreover, I record all defects and decisions. Thus, I create a clear audit trail. Therefore, I can use the results to decide on the release of the work product.

I focus inspections on verification. Specifically, I ask inspectors to check adherence to standards, norms, and regulations. Likewise, I ask them to evaluate the work product against agreed objectives. Consequently, inspections work well for high-risk or safety-critical systems. In addition, I use them for milestone or final versions. However, I use informal reviews for early drafts. Nevertheless, I prefer inspections for decisions that require traceability and accountability.

I follow a strict, documented procedure. First, I plan the inspection and define criteria. Second, I distribute the work product and checklists. Third, I allow individual preparation time. Fourth, I conduct the meeting led by the moderator. Fifth, I assign rework tasks and verify fixes. Finally, I document closure and metrics. In this way, I keep the process measurable and repeatable.

I measure the results. For instance, I track error rate, stability of requirements, and degree of linking between artifacts. Additionally, I check traceability ratios, completeness, and correctness. However, I note that content checks often require human inspection. Thus, I combine automated checks for existence and consistency with manual reviews for correctness. Consequently, I improve quality while keeping effort reasonable.

I integrate inspections into different development approaches. For example, in agile projects, I align inspections with ceremonies like refinement, planning, and sprint review. In contrast, I apply full inspections in traditional, plan-driven projects. Therefore, I adapt the level of formality to the project risk. Moreover, I involve a moderator whenever independence and objectivity matter.

I emphasize roles and behavior. Specifically, the moderator maintains focus and enforces rules. Meanwhile, inspectors bring specific expertise and prepare in advance. Likewise, the author listens and clarifies. In addition, I expect all participants to commit to quality and to invest the necessary time. Otherwise, the inspection loses effectiveness.

I use inspections to drive decisions. For example, I may use inspection outcomes to release a work product to the next development stage. In safety-critical contexts, I may require inspections before final implementation. As a result, inspections reduce risk and increase confidence in product quality. Finally, I recommend inspections when requirements, regulations, or safety demands make correctness essential.
