When a senior engineering or operational leader leaves a business, the pressure to fill the vacancy can be immediate. Production still needs to run, teams need direction, and important decisions cannot always wait. But should the business appoint a permanent replacement, bring in an interim professional or consider both? 

For manufacturing and engineering businesses, the answer will depend on the circumstances. A permanent appointment may be the right choice when long-term leadership and business development are the priorities. Interim support can be valuable when experienced leadership is needed quickly, whether to maintain operational continuity, manage a period of change or deliver a specific project. 

However, as Matt Greenberg, Associate Director at Technical Network, explains, one of the challenges he is seeing when working with clients is the difficulty businesses can have committing to a permanent appointment. 

“When it comes to permanent appointments, businesses can become so concerned about making the wrong hiring decision that they end up making no decision at all.” 

It is an understandable concern, particularly when a senior appointment carries significant responsibility. However, leaving a position vacant for too long can create problems of its own, from resource gaps and existing employees taking on additional responsibilities to increased operational risk and pressure on already stretched teams. 

The challenge is to understand what the business needs, how quickly it needs to act and which type of appointment is most likely to deliver the required results. 

When is a permanent appointment the right choice? 

A permanent appointment is often the best option when a business needs consistent leadership over the longer term. Roles such as Engineering Director, Operations Director and Technical Director can have a lasting influence on business performance, from improving manufacturing processes and developing technical capability to building teams and delivering strategic objectives. 

These responsibilities take more than technical expertise. A successful leader needs to understand the business, build relationships across departments and establish priorities that support its future direction. In complex manufacturing environments, particularly those operating across multiple sites, developing that understanding can take time. 

A permanent appointment can provide the continuity needed to strengthen internal processes, develop people and deliver sustained improvements. It may also be appropriate when a business is expanding, restructuring its leadership team or replacing someone whose departure has created a long-term gap. 

The difficulty is often knowing exactly what the business needs from the new appointment. Replacing someone on a like-for-like basis may seem the obvious starting point, but the role may need to change if the company's strategy, technical requirements or operational priorities have moved on. 

There is also a balance between making a considered decision and allowing the search to continue indefinitely. Senior appointments should never be rushed simply to fill a vacancy, but delaying a decision because no candidate appears to meet every requirement can leave the business without the leadership it needs. 

A clear understanding of the essential experience, the challenges the individual will face and the contribution expected from them can help businesses make a more confident decision. 

When does interim leadership make sense? 

Interim leadership can be particularly useful when a business needs experienced support for a defined period or a specific challenge. This might involve overseeing a factory improvement programme, managing a restructuring, introducing a new production process or maintaining leadership following an unexpected departure. 

For example, a manufacturer preparing to implement a significant operational change may need an experienced leader who can take responsibility for delivery over a set period. An interim appointment can provide that expertise without requiring the business to create a permanent role around a temporary requirement. 

Interim support can also help when a senior vacancy needs immediate attention, but the business is not ready to commit to a permanent appointment. Bringing in an interim professional may help maintain continuity while the organisation considers its longer-term requirements and carries out a permanent search. 

However, interim leadership is not necessarily the easier option. 

Matt has observed a broader pool of candidates considering interim opportunities amid the challenges of securing permanent roles. At the same time, he is seeing clients become increasingly specific about the experience they want from an interim appointment. 

As he explains: 

“Clients are becoming increasingly specific in their requirements, often expecting candidates to meet virtually every element of the brief and hit the ground running. This can make finding the right interim candidate just as challenging.” 

For businesses, this presents a practical challenge. An interim professional is often expected to make an immediate impact, which means relevant experience and the ability to address the immediate problem are particularly important. However, expecting one candidate to meet every element of an extensive brief can make the search more difficult than necessary. 

The key is to be clear about what the individual needs to achieve. If the priority is stabilising an operation, delivering a project or providing temporary leadership, the brief should reflect those requirements rather than attempting to cover every possible future need. 

How should businesses decide between permanent and interim? 

The starting point should be the business challenge, rather than the type of contract. 

If the organisation needs someone to develop a long-term strategy, build leadership capability and take ongoing responsibility for performance, a permanent appointment is likely to be the more appropriate route. If the immediate requirement is to manage a specific project, cover a vacancy or provide specialist expertise during a period of change, interim support may be more suitable. 

Timing is another important consideration. Where a leadership gap is already affecting operations or placing additional pressure on the existing management team, the business needs to consider how that gap will be managed while the search takes place. 

It is also worth looking at the capabilities already available within the organisation. A strong management team may need temporary specialist support to deliver a particular project, whereas a business facing longer-term challenges may need a permanent leader to establish a new direction and develop the people around them. 

The brief itself can make a significant difference. Employers should distinguish between the experience a candidate must have and the qualities that would be beneficial. This is particularly important when recruiting interim professionals, who may be expected to deliver results within a relatively short timeframe. 

Being realistic does not mean compromising on quality. It means focusing on the experience and capabilities that will make the greatest difference to the business, rather than ruling out suitable candidates because they do not meet every desirable criterion. 

Can permanent and interim appointments work together? 

Permanent and interim leadership do not have to be competing options. In some circumstances, using both can help a business address an immediate need without losing sight of its longer-term priorities. 

For example, an interim leader could maintain operational continuity following a senior departure while the business undertakes a permanent search. This gives the organisation time to identify the experience and leadership qualities its needs for the future, rather than making a permanent appointment under pressure. 

The two appointments will not necessarily require the same experience. An interim professional may be brought in to resolve an immediate challenge or deliver a defined programme, while the permanent leader will need to take responsibility for the wider direction of the function over time. 

Clear responsibilities are important to ensure that the interim arrangement supports the permanent appointment. The business should understand what needs to be delivered in the short term and how that work will fit with its longer-term plans. 

This approach will not suit every situation, but it can be worth considering where a vacancy needs immediate attention, and the permanent appointment requires a more considered search. 

Getting the brief right 

Whether the appointment is permanent or interim, a clear brief is essential. Employers need to understand the business challenge, the responsibilities involved and what success should look like before beginning the search. 

In manufacturing and engineering, senior roles often combine technical expertise, operational responsibility, people leadership and commercial decision-making. Two positions with similar titles may require very different experience depending on the organisation, its operating environment and the challenges it faces. 

Taking the time to establish the priorities at the outset can help avoid unnecessary delays and keep the search focused. It also provides a clearer basis for assessing candidates, particularly when the business is under pressure to make an appointment quickly. 

Technical Network works with businesses across manufacturing and engineering on senior appointments, bringing an understanding of the sector and the requirements involved in leadership hiring. Establishing what the business needs from the outset helps employers assess the options available and determine whether permanent or interim support is the most appropriate solution. 

Making the right decision for your business 

The decision between permanent and interim leadership ultimately comes down to what the business needs to achieve and when. A permanent appointment may provide the leadership and continuity required for long-term growth, while an interim professional can offer valuable support when an immediate challenge needs to be addressed. 

As Matt Greenberg's experience with clients highlights, businesses can face difficulties with either route. Concerns about making the wrong permanent appointment can delay important decisions, while increasingly specific expectations can make it harder to secure an interim professional who meets every requirement. 

The answer is not to lower expectations or rush a senior appointment. It is to establish what the business genuinely needs, identify the experience that matters most and set realistic expectations for the search.
