Matrix for maintaining, refactoring or rewriting a PHP application

There is no universal answer. This matrix forces comparison of risk, knowledge, data, coverage, change cost and continuity before choosing a path.

Engineering tools for diagnosis, option comparison, architecture review and turning decisions into a phased plan.

Preparation

Complete the resource with evidence, not ideal answers

A checkbox helps when it represents a verified situation and leads to a conversation or decision.

Bring together people who understand product, development and operations. For each section, identify repositories, configuration, metrics, incidents, screenshots or examples that justify the answer. If evidence does not exist, record the uncertainty: it may matter more than completing the checkbox.

At the end, group findings by impact and dependency. Separate immediate controls, required investigation and structural improvements. The result should state what will be done, who can decide it and how it will be verified, avoiding a wish list without priority.
