You define an interim manager’s mandate clearly by describing the assignment, authorities, objectives, and reporting lines in writing in a mandate document that is approved by all parties involved. A well-drafted mandate prevents misunderstandings, protects both the organization and the interim manager, and ensures that the assignment heads in the right direction from the very start. In this article, we answer the most frequently asked questions about drafting a clear interim management mandate.

What must be included in an interim management mandate?

An interim management mandate must contain at least the following elements: a clear description of the assignment, the start and end date, the authorities of the interim manager, the reporting line, the compensation arrangements, and the measurable objectives. Without these basic components, the structure needed to properly manage and evaluate the assignment is missing.

In addition to these mandatory components, it is also useful to make agreements about availability, confidentiality, and the way interim evaluations are conducted. Also consider practical matters such as access to systems, budget that the interim manager may deploy independently, and the way decisions are documented. The more concrete the mandate, the less room there is for differences in interpretation that cause problems later on.

How do you determine the scope and authorities of an interim manager?

You determine the scope and authorities of an interim manager by defining in advance which decisions he or she may make independently, which teams or departments fall under his or her responsibility, and where the boundaries of the assignment lie. A clear delineation prevents the interim manager from having too little power to act or, conversely, from exceeding his mandate.

Start by answering three questions: What needs to be achieved? What resources are available for that? And which decisions require approval from a higher authority? The answers to these questions form the basis of the scope definition. Then specify which budgets, people, and processes the interim manager may direct. Record this not only internally, but also discuss it explicitly with the interim manager, so that there is mutual understanding about what the assignment entails and what falls outside it.

With interim management, the rule of thumb is: give the interim manager enough mandate to be effective, but ensure clear escalation points for decisions that structurally affect the organization.

What is the difference between a mandate and a job description?

A mandate describes what an interim manager must achieve and with what authorities, while a job description describes which tasks and responsibilities a permanent employee carries out on a structural basis. The mandate is results-oriented and time-bound; the job description is process-oriented and permanent in nature.

This distinction is important because interim managers are not appointed to fill a position, but to complete a specific assignment. A job description outlines the role in the day-to-day functioning of the organization. A mandate outlines the mission: what needs to be changed, built up, or stabilized within a given period. Anyone who manages an interim manager as if they were a permanent employee misses the power of interim management as an instrument for targeted change.

How do you record objectives and results in a measurable way?

You record objectives in a measurable way by formulating them as concrete results with a clear timeline and an objectively verifiable criterion. Preferably use the SMART method: objectives are Specific, Measurable, Acceptable, Realistic, and Time-bound. Avoid vague formulations such as “improve the organization” or “optimize processes” without specifying what that means in practice.

Preferably formulate objectives as end results, not as activities. Not “the interim manager coaches the team,” but “the team operates independently and meets the set productivity targets by the end of the second quarter.” Also make agreements about interim milestones, so that you do not only find out at the end of the assignment whether the goals have been achieved. Regular check-ins based on those milestones give you the opportunity to make adjustments when necessary.

Who must approve the mandate within the organization?

The mandate of an interim manager must be approved by the direct client, the HR responsible, and, depending on the authorities being granted, the general director or the management team. The larger the mandate, the higher up in the organization the approval must be sought.

A common mistake is that the mandate is only discussed with the direct supervisor, while other stakeholders are affected by it later on. Therefore, also involve the department heads or team leaders who work directly with the interim manager. This ensures that everyone affected by the assignment is aware of the authorities and expectations. A mandate that is broadly supported internally gives the interim manager the credibility and authority to act effectively.

What are common mistakes when drafting an interim mandate?

The most common mistakes when drafting an interim management mandate are: objectives that are too vague, unclear authorities, no agreements about reporting, and insufficient involvement of internal stakeholders in the approval process. These mistakes lead to delays, frustration, and assignments that do not deliver the desired result.

Other common pitfalls are:

  • Agreeing on the mandate verbally instead of recording it in writing
  • Expanding the scope during the assignment without formally amending the mandate
  • Not scheduling interim evaluation moments
  • Expecting the interim manager to figure out his or her own authorities
  • Not including an exit strategy or handover plan in the mandate

A good mandate is a living document. Adjust it when the situation changes, but always do so in consultation and with formal approval. This keeps the assignment clear for all parties involved.
