Short answer: a merger integration workshop brings the leaders of two combining organisations together to agree how the new organisation will make decisions, which integration priorities come first and who owns each one. The most useful sessions focus on decision rights and trade-offs, not culture-building exercises. A good facilitator is neutral between the two sides, so neither leadership team feels the session belongs to the other.
Most of the value in a merger or acquisition is won or lost after the deal closes. The legal and financial work is usually thorough. The leadership work - agreeing how two teams with different habits, loyalties and ways of deciding will run one organisation - is often left to chance. This guide explains what integration workshops should cover and how to run them well.
Why merger integration stalls at leadership level
- Two sets of decision rules: each organisation had its own way of deciding who approves what. Until a single set is agreed, decisions either stall or get made twice.
- Unspoken loyalties: leaders protect people, budgets and systems from their original organisation, often without saying so.
- Too many priorities: integration plans list dozens of workstreams, and nobody says which ones matter most in the first 100 days.
- Status uncertainty: while roles are unclear, people avoid taking positions in meetings, so problems surface late.
- Mixed messages: leaders explain the integration differently to their own teams, and staff fill the gaps with rumour.
What an integration workshop should produce
| Output | What it settles |
|---|---|
| Decision rights map | Who decides what in the combined organisation, at which level, and how disputes are escalated |
| Integration priorities | The few workstreams that matter most in the first 100 days, ranked, with what will wait |
| Ownership register | A named owner, deadline and success measure for every priority |
| Risk owners | The biggest integration risks, each with a leader responsible for managing it |
| Communication commitments | What every leader will tell their teams, and when, so the story is consistent |
| Review plan | When the leadership team will check progress and reset priorities |
A sequence of workshops that works
Integration is rarely settled in one session. A practical sequence is:
1. Decision rights reset (before or soon after day one)
A half-day session in which the combined leadership team agrees who decides what. This removes the most common source of early friction and slow decisions.
2. Integration priorities workshop (first 30 days)
A full-day session that ranks integration workstreams, names what will wait, assigns owners and agrees how success will be measured at 30, 90 and 180 days.
3. 90-day review (around day 90)
A short facilitated session to check what has held, unblock stalled commitments and reset priorities as the new organisation settles.
How to run integration sessions well
- Use a neutral facilitator. If the session is run by someone from either organisation, the other side will treat it as theirs. An external facilitator has no loyalty to either.
- Collect views privately first. Pre-work and silent exercises let leaders state real concerns before they have to defend them in front of new colleagues.
- Mix the groups deliberately. Small groups with leaders from both organisations build working relationships faster than plenary discussion.
- Name the trade-offs. Integration means some systems, processes and roles will not survive. Saying so openly, with reasons, is better than leaving it to rumour.
- Write everything down. In a period of uncertainty, a written decision log is the single most useful thing a leadership team can share with the wider organisation.
How Echelon supports merger integration
Echelon designs integration sessions around two of its core formats. The Decision-Rights Reset is a half-day session that maps who decides what and agrees escalation rules. The Transformation Alignment Workshop is a full day that sets integration priorities, success measures at 30, 90 and 180 days, risk owners and communication commitments. Both end with a written decision log and a 30-day follow-up call, and an optional 90-day review keeps the integration on track.
Half-day sessions cost £2,500 to £3,500 and full-day sessions £4,500 to £6,000. For larger combined leadership groups, Dr Andrew Greenland works with associate facilitators he knows and trusts. See our pricing and how we work.
Frequently Asked Questions
What is a merger integration workshop?
A facilitated session in which the leaders of two combining organisations agree how the new organisation will make decisions, which integration priorities come first and who owns each one. It usually produces a decision rights map, ranked priorities and an ownership register.
When should integration workshops happen?
Ideally a decision rights session before or just after the deal completes, a priorities workshop within the first 30 days and a review at around 90 days. Earlier is better, because unclear decision rights slow everything else down.
Why use an external facilitator for merger integration?
Because neutrality matters. A facilitator from either organisation will be seen as representing that side. An external facilitator has no loyalty to either team, which makes it easier for leaders to speak openly.
How much does a merger integration workshop cost?
With Echelon, a half-day decision rights session costs £2,500 to £3,500 and a full-day integration priorities workshop costs £4,500 to £6,000, including preparation, a written decision log and a 30-day follow-up call.
Who should attend a merger integration workshop?
The senior leaders from both organisations who will run the combined business, usually 6-15 people. Larger groups can work well with associate facilitators running parallel small groups.
