Overview
This M&A Integration Workspace template is built for the period between deal close and Day 100, when teams need a shared place to coordinate readiness, execution, decisions, and follow-through. It organizes the work around the actual integration flow: kickoff, Day 1 readiness, workstream execution, synergy tracking, Day 100 planning, and retrospectives. The channels are set up for real operating rhythms, not generic chatter, so the team can separate day-to-day updates from executive risk review and decision logging.
Use this template when multiple functions need to move in lockstep across a merger, acquisition, carve-out, or major restructuring. It is especially useful when the integration has a clear DRI for each workstream and when leadership wants a visible record of milestones, dependencies, and unresolved risks. The pinned resources give the workspace a practical starting point: an Integration Charter, Day 1 Readiness Checklist, Synergy Model and Assumptions, Decision Log, and Day 100 Plan.
Do not use this template as a simple project tracker for routine internal initiatives. It is also not the right fit if the work is fully contained within one team or if there is no meaningful post-close coordination across functions. The template is strongest when the team needs Conway’s Law alignment: the workspace mirrors the integration structure, the task lists mirror the workstreams, and the check-ins mirror the decision cadence. If you need a lighter-weight launch plan or a single-department SOP, a different template will be easier to maintain.
What's inside this template
Members
This section defines the role-based owners who will carry the integration work, so the workspace reflects the actual operating structure.
Channels
These channels separate kickoff, execution, decisions, readiness, planning, and retrospectives so updates do not get buried in one feed.
-
integration-kickoff
Launch planning, scope alignment, integration principles, and program setup.
-
day-to-day-execution
Primary coordination channel for active workstream updates, blockers, and handoffs.
-
decisions-log
Formal decisions, approvals, and rationale for integration choices.
-
day-1-readiness
Readiness tracking for launch-critical items, cutover dependencies, and go-live risks.
-
day-100-planning
Longer-horizon integration planning, synergy realization, and post-close optimization.
-
retros-and-lessons-learned
Post-milestone retrospectives, lessons learned, and process improvements.
Check ins
The check-in cadence sets the rhythm for status, escalation, and learning, which is critical when many functions depend on each other.

Day 1 readiness review
Final readiness assessment and go-live decision.
-
Day 30 stabilization review
Assess early post-close issues, handoffs, and remediation progress.
-
Day 100 planning checkpoint
Confirm post-close priorities, synergy progress, and remaining gaps.
-
Day 100 review
Evaluate integration outcomes, synergy realization, and lessons learned.
Task lists
The task lists break the integration into stage-based work with a clear DRI, making it easier to track ownership and dependencies.
-
Day 1 Readiness
Critical launch items that must be complete before close or go-live.
-
Integration Workstreams
Stage-based execution tasks across core functional workstreams.
-
Day 100 Planning
Post-close optimization, synergy realization, and operating model stabilization.
-
Synergy Tracking
Track cost, revenue, and operational synergies against the integration business case.
-
Decision Log
Capture material integration decisions, approvals, and rationale.
Hill charts
Hill charts give a quick visual read on where the integration is progressing and where work is still uphill.
-
Day 1 Readiness Hill
Tracks launch-critical workstreams from planning through go-live.
-
Day 100 Integration Hill
Tracks post-close optimization and synergy realization workstreams.
Default apps
Default apps connect the workspace to the tools the team already uses for documents, tickets, and status updates.
Integrations
Integrations keep source files and execution systems connected so the workspace stays current without duplicate manual updates.
- Slack
- Google Drive
- Microsoft Excel
- Jira
Pinned resources
Pinned resources surface the core deal documents and operating artifacts that every workstream needs to reference.
- Integration Charter
- Day 1 Readiness Checklist
- Synergy Model and Assumptions
- Decision Log
- Day 100 Plan
How to use this template
- 1. Set the integration charter, Day 1 checklist, synergy model, and Day 100 plan as the first pinned resources so every owner works from the same source documents.
- 2. Assign each member role, such as Integration Program Manager, Finance Lead, HR Lead, IT Lead, Legal Lead, and Communications Lead, and make sure every task list has one clear DRI.
- 3. Use the integration-kickoff channel to confirm scope, milestones, dependencies, and the check-in cadence before work starts.
- 4. Run the day-to-day-execution channel for workstream updates, then move unresolved risks and decisions into the decisions-log channel with an owner and due date.
- 5. Review Day 1 readiness and Day 100 planning against the milestone dates, update hill charts to show progress, and close the loop in retros-and-lessons-learned after each major checkpoint.
Best practices
- Keep each channel tied to a specific operating purpose, such as kickoff, execution, decisions, readiness, planning, or retrospectives.
- Name every task with a single DRI and a milestone date so ownership is never ambiguous.
- Update the Day 1 Readiness Hill and Day 100 Integration Hill only after the underlying task list changes, not as a standalone status exercise.
- Use the Wednesday executive risk review to escalate blockers that need sponsor decisions, not to rehash routine status.
- Track synergy items in the same workspace as the workstream tasks so assumptions, actions, and outcomes stay connected.
- Log decisions with enough context to explain the tradeoff, the approver, and the workstream it affects.
- Keep default visibility broad enough for coordination, but restrict sensitive deal materials to the right audience and linked source files.

Common use cases
Frequently asked questions
What is included in the M&A Integration Workspace template?
This template includes integration-focused channels, weekly check-ins, milestone tracking, stage-based task lists, hill charts, and pinned resources for the core integration documents. It is set up around Day 1 readiness, Day 100 planning, synergy tracking, and decision logging so the team can work from one shared workspace. The structure is meant to be cloned and then assigned to the actual integration leads, not used as a generic project space.
Who should run this workspace during an integration?
It is usually run by the Integration Program Manager or PMO lead, with workstream owners acting as DRIs for their own task lists. The executive sponsor should use the Wednesday risk review channel or check-in to resolve blockers and make decisions quickly. Finance, HR, IT, Legal, Operations, and Communications leads typically participate based on the deal scope.
How often should the check-ins happen?
The template is built around a weekly Monday integration status, a weekly Wednesday executive risk review, and a biweekly retrospective. That cadence works well because it separates execution updates from decision escalation and lessons learned. If the deal is smaller, you can reduce the number of touchpoints, but keep the Monday status and a regular risk review.
What kinds of integration workstreams fit this template?
It fits workstreams such as systems and IT cutover, finance and reporting, HR and people operations, legal entity setup, communications, customer transitions, and procurement or vendor consolidation. The task lists are stage-based, so each workstream can track its own Day 1 actions, stabilization tasks, and Day 100 goals. If a workstream does not affect integration milestones, it probably belongs elsewhere.
How does this template help with Day 1 readiness?
The Day 1 Readiness channel, milestone, and checklist give the team a single place to confirm what must be complete before close or launch. It helps owners surface missing approvals, unresolved dependencies, and cutover risks early enough to act. The common pitfall it prevents is assuming readiness is complete because tasks are underway rather than verified.
How does it support synergy tracking?
The Synergy Tracking task list and pinned Synergy Model and Assumptions resource let the team track cost, revenue, and operational synergy items against the integration plan. This keeps assumptions visible when owners update forecasts or mark items complete. It is especially useful when finance needs a clean trail from target, assumption, action, and realized outcome.
Can this workspace be customized for different deal sizes or structures?
Yes. You can simplify it for a small tuck-in acquisition or expand it for a complex carve-out, cross-border deal, or multi-entity merger. The main customization points are the members, workstreams, milestone dates, default visibility, and which integrations you connect for source documents and task updates.
What integrations are most useful with this template?
Slack is useful for alerts and decision follow-up, Google Drive or Microsoft Excel for deal documents and synergy models, and Jira for technical workstreams and cutover tasks. The best integration touchpoint is to connect the systems where owners already update status so the workspace stays current. Avoid duplicating every source of truth manually if the team already maintains a controlled file or ticket system.
What are the most common mistakes when using an M&A integration workspace?
The most common mistakes are leaving channels unused, assigning tasks to functions instead of a single DRI, and treating Day 100 as a finish line rather than a stabilization checkpoint. Another frequent issue is logging decisions without linking them to the workstream or milestone they affect. This template works best when each item has a clear owner, date, and next action.
