Gemini for HRIS Implementation Leads in Retail Banking: Write a Change Management Plan That Prevents System Rejection

You are a specialist HRIS implementation lead with 12 years of experience managing HR technology deployments in regulated financial services environments. Help me build a change management plan so I can hit 85% active user adoption within 60 days of go-live. My situation: - Bank type: [e.g., retail bank / investment bank / building society / credit union] - HRIS being implemented: [e.g., Workday / SAP SuccessFactors / Oracle HCM / Cornerstone] - Employee population affected: [NUMBER and PROFILE e.g., 3,000 branch staff / 500 corporate HR users] - Previous failed HR system rollout in the last 5 years: [YES with details / NO] - Regulatory constraints on HR data migration: [e.g., FCA / PRA / Basel III data governance / GDPR] - Go-live date and current phase: [DATE and e.g., design / build / UAT / training] Deliver: 1. A stakeholder resistance map: the five employee groups most likely to resist the new system, their specific objection type (usability / job security / extra workload / distrust of data), and the targeted message for each group 2. A branch-level champion network design: how to identify, recruit, brief, and support 50 system champions across the branch network — with a time commitment that fits around operational shifts 3. A training sequencing plan that accounts for shift patterns: how to deliver mandatory system training to 3,000 branch staff without pulling them off the floor simultaneously 4. A go-live communication calendar: 12 weeks of communications from pre-announcement to post-go-live — with the channel, sender, message purpose, and success metric for each touchpoint 5. A hypercare plan for the first 30 days post-go-live: staffing model for the support desk, triage criteria for escalation to vendor, and the daily metrics that confirm adoption is on track 6. A manager enablement pack: the five system tasks every line manager must be able to complete independently by go-live — with a 20-minute self-paced guide for each task 7. A regulatory compliance sign-off checklist: the documentation an FCA-regulated bank must produce to demonstrate that the HRIS migration meets data integrity and audit trail requirements 8. A 90-day adoption measurement report template showing active user rate, transaction completion rate, and help desk ticket volume — structured for the CHRO and CIO to review jointly **Write every output as something the implementation programme team can execute inside the go-live timeline — no consulting frameworks that require separate workstreams.**
