Most organisations treat the decision to bring in an interim manager or a consultant as the hard part. They screen for experience. They test for chemistry. They look for someone credible enough to walk into a difficult room and hold it. Once they have found that person, they hand over the mission and step back.
That is usually where the trouble starts.
Bringing in an external expert is not a procurement decision. It is an act of delegation. And delegation, done properly, does not end at the handover.
If an expert cannot succeed under the conditions you have created, the fit that got them hired stops mattering on day one.
Delegation Was Never Just Forwarding a Task
Somewhere along the way, we reduced delegation to its most visible step: passing something to someone else. Forward the email. Assign the ticket. Name the owner. Move on.
Classic management teaching describes something far more demanding. Delegating means transferring responsibility for an outcome. And for that transfer to hold, several things must travel with it:
- A clear picture of what “done” looks like — not just where to start.
- Enough authority to match the accountability being taken on.
- Access to the people, information and resources the work depends on.
- Defined boundaries — what can be decided alone, and what comes back for a decision.
- Someone to escalate to when reality stops matching the plan.
Strip any of these away and you have not delegated. You have relocated a problem.
Good managers know this instinctively with their own teams. They spend time setting people up. Yet the same managers often drop the discipline the moment the person comes from outside the organisation.
An Interim Engagement Is Delegation, Not Procurement
When a company engages an interim executive or a consultant, it delegates a named, defined mission to someone it does not employ. Stabilise the programme. Rebuild the governance. Deliver the transition. The label changes; the mechanics do not.
Selection matters here. Experience, presence and character are real factors. A poor fit is hard to recover from. But selection is necessary, not sufficient. Even the best-matched expert will fail if nobody built the conditions for the mission.
This is where planning quietly does its damage. Planning is the least glamorous phase of any project. So it is the first thing people compress when they are impatient to see movement. Interim engagements suffer from the same reflex. The client signs the contract, sets the expectation, and then assumes a senior professional will simply arrange the rest.
Some of it, they will — that is part of what they are paid for. But navigating ambiguity is one thing. Being left to invent the preconditions for your own mandate is another.
Who Owns the Mission Statement?
One question deserves an answer before all the others, because it quietly shapes them. Who is responsible for defining the mission itself?
The honest answer is that both sides contribute. A capable interim manager helps sharpen the brief, challenges vague framing, and turns rough intent into something deliverable. Often they do it better than the client could alone. So in RACI terms, the R for the mission statement is genuinely shared. Candidate and recruiting manager work on it together.
The A is not. Accountability for the mandate sits with the manager bringing the expert in. It is their organisation, their sponsor, their political capital. And it is ultimately their call on what success means. An interim manager can shape the mission. But they cannot grant themselves the authority behind it.
Blurring that line is where engagements drift. Sometimes the client quietly leaves the expert to define the mandate as well as deliver it. In effect, the client hands over something that was never theirs to give away. And it keeps none of the accountability that should have anchored the work.
This is not a niche concern. Professional interim management bodies keep returning to the same foundation. DDIM in Germany, among the most established in Europe, is one example. They stress a clearly defined mandate, an identified sponsor, and accountability that stays on the client side. Experienced interim managers feel this nuance whether or not anyone raises it. So a good one will not simply notice a missing or borrowed mandate. They will walk the client through fixing it before the clock starts.
Facilitation Is Not About Comfort
The word missing from most engagement kick-offs is facilitation.
It is easy to hear that word and think of soft things: a warm welcome, a tidy desk, a friendly onboarding. That is not what this is about. Facilitation, in the sense that matters, means deliberately building the prerequisites for success. You build them before the expert has to deliver against them.
It is the sponsor who is genuinely available, not just named on a slide. It is the decision rights written down before the first disagreement, not improvised during it. It is access to systems and people, arranged in advance. It is the existing responsibilities that someone has formally moved or paused. And it is the internal stakeholders who already know why this person is here and what they can do.
None of this is for the expert’s comfort. It is for the mission. Every prerequisite missing on day one costs a week. That is a week the expert spends manufacturing authority instead of using it.
“They’ll Sort It Out Themselves” Is a Delegation Failure
Here is the most expensive assumption a client can make. A capable expert does not need anyone to set the conditions for them.
It sounds like a compliment. We hired a senior person, they can figure it out. In practice, it is the same delegation failure from earlier, dressed up as confidence. Someone forwarded the task. Nobody built the conditions. And because the person is experienced, no one notices the gap until the momentum is already gone. I have watched capable people spend their first month building authority that the client should have granted before they arrived.
This is also where the risk quietly transfers. The client keeps the outcome they wanted. The expert inherits accountability for a mission that never had its preconditions in place. Often they inherit the reputational cost too, when it stalls. From the outside, an assignment built to fail rarely looks like a facilitation problem. It looks like the expert underdelivered.
So for anyone stepping into these roles, that asymmetry is worth taking seriously before signing. Accountability without the conditions to act on it is not a mandate. It is exposure.
The Conversation to Have Before Day One
The remedy is not complicated, and it is rarely lengthy. Most of it fits into a single deliberate conversation before the engagement begins.
Before the expert starts, both sides should be clear on:
- The mission in one sentence — and what “done” actually looks like.
- The authority that comes with the accountability, stated explicitly.
- Who the sponsor is, and how often they will genuinely be available.
- Which decisions the expert can make alone, and which must be escalated.
- What access to people, data and systems is required — and whether it is already arranged.
- Which existing responsibilities move, pause or stay when the expert arrives.
For a larger transformation, treat this setup as a small piece of work in its own right. Run a short phase that defines the conditions before anyone has to perform against them.
Selecting the right expert answers one question: can this person do the job? Setting the conditions answers a second, and more decisive one: can they do it here.
The first is hiring. The second is delegation. Skipping it does not make the mission easier. It only moves the moment of failure to a point where it is harder to fix.
