Interim professionals aren’t simply a quick fix - they’re catalysts. When brought in at the right moment, they stabilise teams, unblock progress and create clarity. Here’s what the first 90 days really look like inside a high-impact interim assignment.
Week 1: Stabilise and Listen
Great interims don’t rush to fix everything on day one.
Instead, they:
- Understand the team’s pressure points
- Assess reporting, processes, and workflows
- Build trust quickly with small wins
This week sets the tone for everything that follows.
Weeks 2–4: Build Structure and Momentum
Once the landscape is clear, strong interims put structure where it’s missing:
- Tidying reporting deadlines
- Improving communication
- Clarifying roles and responsibilities
- Supporting the leadership team during pinch points
These changes create immediate breathing room for the business.
Month 2: Drive Progress
This is where interims add real value.
They identify operational blockers and lead tangible improvements:
- Refreshing processes
- Getting projects back on track
- Guiding teams through complexity
Interims bring an outside perspective – and often spot solutions the team has been too stretched to see.
Month 3: Leave the Function Stronger
By the end of 90 days, the focus shifts from stabilisation to legacy:
- Documenting processes
- Preparing for handover
- Supporting the transition to permanent hires
- Ensuring momentum continues after they leave
A successful interim becomes the bridge from “under pressure” to “back in control”.
