When facing a complex situation, organizations sometimes hesitate between two types of intervention: hiring a consulting firm or assigning a mission to an interim manager.
The confusion is frequent, as the two approaches may seem similar at first glance.
In reality, they address different needs at different moments in an organization’s life.
A consulting firm generally intervenes when the main question is:
What should we do?
Its role is to analyze a situation, structure a diagnosis, propose scenarios, and formulate recommendations. Consulting brings methodology, perspective, and analytical capacity to inform decision-making.
Interim management usually intervenes at another moment.
When the question is no longer purely strategic but operational:
Who will carry the decision now?
Who will hold the function, lead the project, make the trade-offs, and deliver results within a short timeframe?
The interim manager does not merely analyze or recommend.
They enter the organization, take responsibility for a function, and act at the core of the management system.
From this perspective, interim management and consulting are not competing solutions.
They are complementary responses to different phases of the same problem.
The real question is therefore not only one of budget or intervention format.It is primarily about operational responsibility:
Does the organization need an external perspective to analyze the situation — or a leader capable of immediately driving it?
