Architectural Change Impact Analysis

★ 7.7 · general

impact-analysis is a Claude Code skill that evaluates the consequences of architectural changes — retiring a system, upgrading technology, replacing a tool, or migrating to cloud — before any work begins. It accepts a change description along with optional scope (systems, people, process, financial, technical, or all) and depth (quick, standard, comprehensive) parameters, then runs through three phases: defining the change, analyzing impacts, and generating a report. The analysis maps dependencies, calculates cascading failures with recovery paths, identifies affected teams and skill gaps, and quantifies financial exposure including downtime costs, training, and savings. The output includes a one-page summary, detailed breakdowns across systems, integrations, processes, and people, a dependency diagram with criticality levels, RTO/RPO-based contingency scenarios, and a rollback-ready implementation checklist. Built for architects and technical managers who need a clear risk and cost picture before committing to major changes.
