Conduct a comprehensive change impact and readiness assessment for [Company] implementing the new transport management system [TMS_Name] across [Region] before [Go_Live_Date]. Analyze upstream and downstream effects on [Process_Areas] (e.g., load planning, tendering, yard management), identifying impacts by [Roles] (drivers, dispatchers, planners, warehouse leads) and by site criticality. Score each impact against [Readiness_Criteria] (process, people, tech, data, controls). Produce prioritized actions to close gaps, quantified risk exposure, and a path to “business-stable” operations within two sprints post go-live. Output format requirements: (1) Impact Register table [Columns: Process Area, Role, Impact Description, Severity (1–5), Readiness Gap (1–5), Mitigation, Owner, Due Date]; (2) Heatmap of Severity x Readiness Gap by site; (3) Readiness Scorecard summarizing % green/amber/red per workstream; (4) Top-10 Critical Impacts with mitigation narratives (≤120 words each); (5) One-page executive summary stating overall go/no-go readiness with rationale and assumptions. Ensure traceability between impacts, mitigations, and owners, and align definitions of “green” vs “amber” with enterprise standards.
