Inside an Interim Assignment: How Impact Happens in the First 90 Days

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”.
