Mission PMI — M&A → PMI
Most mergers destroy value. Mission PMI is built so yours doesn't.
Mission PMI is Mission Systems' post-merger integration practice — a disciplined, IT-led playbook that turns the deal thesis into a single, working operation. It is PMO management purpose-built for M&A.
The problem
The odds are against integration — unless it is run as a programme.
The execution philosophy
The MDEMT Framework
Integration stalls when alignment, clarity and momentum break down. Mission PMI is run on the MDEMT framework — five pillars that keep every stakeholder locked in and every workstream moving, underpinned by ISOPOSED™ to frame the why and the what, and TORSEMI™ to run the live cadence.
Mission Focused Leadership
Everyone knows the Mission, their Why, their role, and who to escalate to.
Disciplined Planning & Comms Loops
One Plan, One Timeline, One Risk Register — everyone knows what's happening, when, how, and what impacts whom.
Execution Roadmap & Decisions
Clear WHAT, WHY, WHEN, DEPENDENCIES and SUCCESS CRITERIA for every task.
Momentum Management
Issues, impediments and roadblocks surfaced, escalated, expedited and resolved fast.
Transparency & Real-Time Reporting
Board, Sponsors, Leads and SMEs share the same real-time picture.
The four-phase playbook
From two tech stacks to one operation.
Map the Landscape
Inventory both tech stacks — applications, infrastructure, data models, security — and run a full gap analysis. You cannot integrate what you have not mapped.
Rationalise & Prioritise
Decide which platforms survive and which retire. Build the capability model and prioritise integration workstreams by value and risk.
Integrate & Consolidate
Execute the integration roadmap — unified data migration, process harmonisation, operating-model alignment — while tracking synergy realisation.
Stabilise & Optimise
Hypercare, performance monitoring and benefits-realisation reporting, with continuous improvement driven through TORSEMI™.
Matched to the right integration model
Not every merger should be absorbed. Mission PMI selects deliberately across four integration models — so the operating model fits the deal thesis.
How it runs
Run from a Digital Integration Management Office.
Mission PMI runs the integration from a single Digital IMO — one source of truth for plan, risk and progress, so the Board, sponsors and leads share the same real-time picture from Day 1.
The integration runs on a single toolkit
Governed by a clear operating structure
- Executive Leadership —
- Strategic direction, alignment and key decisions.
- Integration Manager —
- Owns the full PMI process, plan and team coordination.
- Steering Committee —
- Governance, scope and risk control from Day 1.
- Change Management —
- Employee communications, cultural adoption and resistance.
- Functional Leads — Finance, HR, IT & Operations —
- Integrate their domains across the combined business.
- Cutover Sign-off —
- Human approval required before execution.
Proof
Delivered at the scale that matters.
The same delivery craft behind Mission PMI launched the world's first online eAuction for De Beers — a $250M revenue increase — and stood up eDiamond, the first independent open auction platform for the diamond industry, at $120M year-one revenue.
Case study — STREAMZ
Mission Systems is setting up and driving the PMO behind STREAMZ, a new global film and TV streaming service — running the programme that delivers the end-to-end Script-to-Screen-to-Cash systems alongside the enabling capabilities (Finance, HR, IT, Systems Development, Programme Management, Legal) that stand the business up.
In flight.
