Integration 100-Day Plan
The first 100 days of an integration set the tone for everything that follows — the culture, the relationships, the commercial performance, and the business's ability to realise the value it paid for.
Integration 100-day plan is the detailed operational plan for the first hundred days following a merger or acquisition completion — specifying the actions that must be taken, the decisions that must be made, the communications that must be delivered, and the quick wins that must be achieved to build momentum, demonstrate progress, and prevent the performance deterioration that poor early integration management allows.
The Pain We Solve
You may recognise yourself in one of these.
Three audience scenarios · because the same service produces a different transformation depending on where you are in the business journey.
Scenario 1
The acquirer who has completed a transaction without a detailed day-one and first-100-days plan and is now managing integration reactively
The deal completed on Friday. On Monday morning, the combined business was operating without a clear plan — what was communicated to whom, who was responsible for what, which decisions had been pre-made, and what the first visible evidence of integration progress would be. The first month has been reactive.
Scenario 2
The business whose previous merger failed to capture the energy and momentum of the early integration period
The previous acquisition started slowly. The early months were characterised by uncertainty, inaction, and the accumulation of integration decisions that were deferred rather than made. By the time the integration gained momentum, the best people from the target had left, the clients had become anxious, and the opportunity of the early period had been wasted.
Scenario 3
The leadership team that needs to run two businesses simultaneously while integrating them and has not planned how to do that without neglecting either
The leadership team is responsible for the ongoing commercial performance of both the acquirer and the target while simultaneously managing the integration. The demand exceeds the capacity. The plan that would make it manageable — prioritising the integration actions, delegating the operational management, and sequencing the decisions — has not been designed.
The Impact It Creates
The Moment You Will Feel the Difference.
First 100 days planned before completion — decisions pre-made, communications designed, quick wins identified
Integration momentum built in the critical early period when employee and client impressions are formed
Leadership attention directed to the highest-priority integration actions rather than distributed across everything
Quick wins delivered early to demonstrate progress and build confidence in the integration
What You Receive
The Specific Deliverables.
Tangible outputs · documented, dated, and yours to keep.
- Day 1 readiness plan — what must work from the moment the deal completes
- First 30 days plan — immediate priorities and communication actions
- Days 30-100 plan — integration workstreams, milestones, and decisions
- Quick wins identification and delivery plan
- Leadership time and attention allocation during integration
- 100-day review — assessment of progress and plan for the next phase
The Outcome
Where You Will Be on the Other Side.
The business enters the integration with a plan for every day of the first 100 — so the energy of the deal momentum is channelled into structured progress, the early impressions of employees and clients are positive, and the integration gets off to a start that the rest of the programme can build on.
Primary Focus
Designing the detailed first-100-days integration plan that captures early momentum, delivers quick wins, and sets the tone for the entire integration programme.
KPI Measurement
- Day 1 readiness completion rate
- Quick wins delivered in first 30 days
- Employee impression score at day 30 vs day 100
- 100-day milestone achievement rate
- Integration programme performance correlation with 100-day plan quality

Why We Price This Way
Every engagement is sized around the value we believe we can create with you. The fee is always a fraction of the outcome · typically 10 – 20% of the expected first-year return.
This is how we make sure pricing aligns with results. The conversation is never “what does this cost?” · it is always “what is this worth to your business?” We answer that together in the first call, transparently, and decide the right tier from there.
If we cannot articulate a credible 5–10× return for your specific situation, we will tell you in the first call. That honesty is part of why our clients trust us with the work that matters most.
Why This Conversation Matters
“The first 100 days of an integration are not just the beginning — they are the proof of concept for the entire programme. If the plan is executed well, the rest of the integration benefits from the goodwill, the momentum, and the confidence that a well-managed first hundred days creates. We design the plan that earns those benefits.”
A 90-minute structured strategy session · produces a usable roadmap whether you engage further or not.
