Most quality problems can wait for a permanent hire or a planned improvement project. Some cannot. When certification, a key customer or the stability of the quality function is at stake, the cost of waiting several months for the right permanent appointment can far exceed the cost of an experienced interim. Here are the six situations where we most often see an interim head of quality pay for itself.
Six signs you need an interim
1. Your certification is at risk. A major nonconformity, a suspension warning or a failed surveillance audit puts certificates, contracts and approved supplier status on the line. You need someone who can lead the corrective action, deal credibly with the certification body and restore confidence within a fixed timescale.
2. A key customer has escalated. Red supplier scorecards, controlled shipping, repeated field returns or a formal customer escalation demand senior quality leadership who can contain the issue, run disciplined root cause analysis and represent you in difficult meetings.
3. Your head of quality has left. Recruiting a strong permanent replacement typically takes months. Leaving the role empty, or asking an already stretched manager to cover it, is when audit readiness slips and customer issues escalate.
4. You are growing faster than your systems. A new programme, a new site, a new customer sector or a new standard, including the move to ISO 9001:2026, can expose gaps that a small quality team was never set up to close.
5. Your quality team is firefighting. If the same problems keep returning, corrective actions are closed without effect and the team never gets ahead, the issue is usually leadership and structure rather than effort.
6. You are integrating businesses. After an acquisition or merger, two quality systems, cultures and sets of customer requirements need to become one without losing certification along the way.
What a good interim delivers
A strong interim should be making a difference within days, not months. In the first two weeks, expect an honest assessment of where the real risks lie, immediate containment of anything affecting customers and agreed priorities with the leadership team. Over the following months, the focus shifts to closing out the most significant issues, putting meaningful performance measures in place, strengthening the team and fixing the processes that caused the problems.
Just as importantly, a good interim plans their own exit from the start. Success means leaving a stable, documented function and a capable team, and helping to recruit or develop the permanent successor.
Interim, consultant or permanent hire?
A consultant advises and implements defined pieces of work. A permanent hire builds the function for the long term. An interim takes direct line accountability for the quality function now, with the authority to make decisions and manage people, for a defined period. When the situation needs ownership rather than advice, an interim is usually the right answer, and the two are not mutually exclusive.
How to set an interim up for success
Give a clear mandate with defined objectives and timescales. Provide the authority to act and direct access to the managing director or board. Make sure the wider team understands the role. Agree at the outset how and when the interim will hand over. Interims fail most often not through lack of ability but through unclear authority.
