The use of interim executives has evolved.

While they have been typically brought in for specific projects where organisations do not hold that resource in house, interim executives are also often used to bridge a transition between an outgoing and incoming permanent leader.

However, no longer confined to “holding the fort,” today’s transition interims are trusted to lead transformation, restore stability, and create momentum during periods of change. These assignments require speed, clarity and confidence, and the best interims are valued accordingly.

After more than a decade working as a Partner in interim management, I’ve seen a steady increase in organisations turning to interim leaders to bridge critical leadership transitions when leaving an outgoing leader in post is perceived as too big a risk. In these moments, interim leadership provides an opportunity not just to maintain continuity, but to reset direction and protect long-term value.

Here, I outline the strategies top-performing interims use to succeed, and how organisations can best harness their impact.

What is transition leadership?

Transition leadership is an interim solution used to bridge the gap between two permanent executive appointments. It differs from specialist interim roles, which are typically engaged for a defined project or technical skillset.

While specialist interims are focused on clear output led deliverables, transition leaders are accountable for:

• Stabilising the organisation
• Maintaining momentum
• Leading through uncertainty

Their role is shaped by the organisation’s immediate needs and may sometimes require the additional experience and judgement to deliver pivots in strategy, rather than keeping the business running.

Because transition roles often come up due to unexpected departures or underperformance, they demand decisive, experienced leadership. Typically engaged for 6 – 18 months, they provide continuity, protect value and prepare the business for a successful permanent hire.

This aligns closely with research from Harvard Business Review, which consistently highlights leadership transitions as high-risk periods where clarity, credibility and early action materially affect organisational outcomes.

Interim leadership: 7 tips for success

Appointing an interim leader during a period of transition can feel disruptive. Done well, however, it creates a powerful opportunity to reset direction, accelerate change and prepare the organisation for long-term success.

Drawing on conversations with experienced C-suite interims, we defined a number of strategies to help succeed in a transitional interim assignment.

1 – Leadership before popularity

Transition interims are often appointed precisely because difficult decisions need to be made. While diplomacy matters, avoiding disruption or conflict rarely delivers the outcomes required.

Organisations frequently use interims to make tough, sometimes unpopular changes, protecting the incoming permanent leader’s reputation and enabling them to start with a clean slate. Your mandate is to deliver objectives decisively, with appropriate distance and objectivity.

2 – Define your objectives (quickly)

Unlike permanent leaders, interims do not have the luxury of extended assessment periods. Decisions are often expected within days or weeks, not months.

Misalignment at the outset is one of the fastest ways to derail an assignment, so it’s important to validate expectations and understandings with key stakeholders quickly. Define what success looks like, and secure clear backing for priorities and decisions from key stakeholders. Access to senior decision-makers is critical.

3 – Communicate in the right way

Change creates uncertainty. Clear, consistent communication helps reduce resistance and build confidence.

Effective transition leaders take time to understand the organisation, tailor their message to different audiences and explain not just what is changing, but why. Tough conversations are often unavoidable, but bringing people with you accelerates delivery and reduces friction.

4 – Build strong relationships and empower your team

Temporary status does not remove the need for strong relationships. Impact is delivered through people.

Successful interims will often identify key allies early, empowering them and build a support network that sustains momentum – even when the interim is not in the room. Influence, not authority, is what enables rapid progress.

5 – Understand that you were over hired, for a reason

Interims are intentionally appointed for their breadth of experience and ability to act quickly. For organisations, this is about reducing risk and having assurance that someone has seen these challenges before.  This allows them to diagnose issues, spot opportunities and make informed decisions without lengthy ramp-up.

Success should not be measured by making yourself indispensable. The true measure is the strength of the organisation after the interim exits and the legacy left for the permanent successor.

6 – Commit to your deliverables

Reputation matters in interim leadership. Markets are small and memories are long.

High-performing interims are disciplined about execution, accountability and standards. Commitments made at the outset must translate into tangible outcomes and a well-managed handover to the incoming leader.

7 – Think long-term, but deliver short-term

It’s not easy to deliver immediate results whilst laying the groundwork for the future success of the organisation, especially when it’slikely you won’t be around to see it come to fruition. But this is what you have been hired for.

This requires focus: identifying quick wins that stabilise performance, while making decisions that will support the organisation’s longer-term vision and leadership strategy.

How interim leadership benefits organisations

Demand for interim leadership continues to grow as organisations recognise the risks of leaving gaps in senior leadership  teams . Promoting internally to “hold the fort” may appear cost-effective, but it often limits strategic progress and can create longer-term financial and operational risk.

High-calibre interims provide organisations with:

• Immediate executive capability: Access to experienced leaders with proven change and transition expertise
• Speed: Interim leaders can be secured in weeks rather than the 9–12 months often required for permanent hires
• Decision quality: Time and space to run a thorough permanent search, avoiding rushed appointments
• Stability and confidence: Experienced leadership during periods of uncertainty, maintaining stakeholder and investor confidence

Best practices for maximising interim impact

Interims bring expertise, objectivity and pace, but they perform best when organisations create the right conditions.

Key best practices include:

• Engage a trusted interim partner early: Work with one provider who understands the full interim market and your specific challenge. Fragmented searches rarely improve outcomes and can damage candidate relationships.
• Empower the interim leader: Be clear in how the interim is positioned internally. Language matters – this is a leader appointed to take charge, not simply to maintain the status quo.
• Agree value and outcomes upfront: Interim leaders command a premium for short-term access to experience. Align early on what can realistically be achieved within the timeframe, and how this will support the permanent successor.
