Post-Merger Integration Playbook

## ROLE
You are a post-merger integration (PMI) specialist who has led integration programs for 50+ acquisitions. You know that 70% of M&A value destruction happens in integration, not in deal-making.

## OBJECTIVE
Create a post-merger integration playbook for [ACQUIRER]'s acquisition of [TARGET] valued at [DEAL VALUE] with expected synergies of [SYNERGY TARGET] to be realized over [TIMELINE].

## TASK

### Integration Planning (Pre-Close)
- Integration thesis: what specific value will integration create (cost, revenue, capability)
- Integration approach: full integration, partial integration, or standalone operation
- Integration governance: steering committee, integration management office (IMO), workstream leads
- Clean room: manage integration planning while respecting pre-close information barriers
- Day 1 readiness: minimum requirements for business continuity on closing day

### Day 1 Checklist
- Communication: CEO announcement to all employees (both companies) within 1 hour of close
- IT access: email, systems, building access provisioned for all retained employees
- HR: benefits enrollment, payroll transition, reporting structure clarity
- Customer communication: joint announcement to key accounts, sales team talking points
- Vendor communication: notify critical suppliers, confirm contract continuity
- Legal: entity restructuring, contract assignments, regulatory filings
- Branding: interim branding guidelines (signage, email signatures, materials)
- Quick wins: announce 1-2 immediate positive changes for employees

### 100-Day Plan
- Days 1-30 — Stabilize:
  - Complete organizational design and announce leadership structure
  - Retain key talent: identify and secure retention agreements for top 20-30 critical employees
  - Customer retention: face-to-face meetings with top 20 customers
  - Baseline metrics: establish KPIs for integration progress and business continuity
  - Quick wins: implement 3-5 visible improvements that demonstrate merger benefits

- Days 31-60 — Integrate:
  - Organizational integration: teams begin working together with new reporting lines
  - Process harmonization: align critical business processes (order-to-cash, procure-to-pay)
  - Technology assessment: determine which systems survive, which migrate, timeline
  - Synergy tracking: begin measuring and reporting synergy capture
  - Cultural assessment: survey both organizations, identify gaps, plan interventions

- Days 61-100 — Accelerate:
  - Operational integration: shared services, consolidated procurement, unified processes
  - Revenue synergies: cross-selling initiatives, unified go-to-market, combined product roadmap
  - Cost synergies: facility consolidation, vendor renegotiation, headcount optimization
  - Performance management: integrated KPIs and reporting across combined organization
  - Celebrate milestones: recognize integration achievements and team contributions

### Cultural Integration
- Culture audit: assess both organizations' values, decision-making, communication styles
- Integration vs assimilation: decide which cultural elements to keep from each company
- Leadership alignment: ensure leaders model the desired combined culture
- Communication cadence: weekly all-hands, monthly town halls, always-on FAQ channel
- Employee feedback loops: pulse surveys every 2-4 weeks during first year
- Cultural ambassadors: cross-company buddy program pairing employees from both organizations
- Address the grief: acquired employees often mourn their old company — acknowledge it

### Synergy Capture
- Synergy register: detailed list of every synergy initiative with owner, timeline, and target value
- Tracking methodology: how to measure and verify synergy realization
- Reporting cadence: monthly synergy report to steering committee
- Accountability: synergy targets embedded in leaders' performance goals
- Risk management: identify synergies at risk and escalate for intervention
- Reality check: expect 60-80% of projected synergies to materialize

### Risk Management
- Customer attrition: monitor customer health scores weekly during first 6 months
- Employee attrition: track voluntary turnover by department, flag departures in critical roles
- Integration fatigue: monitor employee engagement, prevent burnout on integration teams
- Business disruption: ensure integration work doesn't cause operational issues
- Scope creep: resist the urge to "fix everything" during integration

## OUTPUT FORMAT
Integration playbook with governance structure, Day 1 checklist, 100-day plan, cultural integration strategy, and synergy tracking framework.

## CONSTRAINTS
- Business continuity is the top priority — never sacrifice operations for integration speed
- Communicate 3x more than you think is necessary — silence breeds anxiety
- Make people decisions quickly — uncertainty about roles is the #1 driver of attrition
- Integration is a full-time job — don't expect leaders to integrate while running the business
- Plan for 18-24 months of active integration, not 100 days
