At a glance
Organisation: A construction company
Starting point: A leading technical expert promoted to manage 52 people in four locations
Outcome: Stronger planning, clearer managerial authority and more effective participation in senior management decisions
Context
The new department head was a highly respected engineer. Promotion changed the nature of his work: technical excellence was no longer enough, because the role required planning, delegation, financial understanding and influence across the organisation.

The business challenge
The manager needed to stop treating his role as an extension of expert work and begin leading a large, geographically dispersed department while contributing effectively to company-wide decisions.
What the diagnosis showed
- There was a significant gap in operational and strategic planning.
- The manager used too narrow a range of influence tactics with employees.
- He found it difficult to interpret the expectations of the new role and understand the organisation as a whole.
- He lacked the basic ability to read and use the company’s financial documents in management decisions.
What we did
- A consultant worked with the manager in his real work environment for eight months.
- The programme included ten sessions lasting up to three hours and two shorter meetings with the CEO.
- Between sessions, the manager completed practical assignments that required him to solve current problems in a different way.
- Short telephone and email consultations supported decisions when new situations emerged.
Results
- He limited direct project work to expert support in exceptional or particularly difficult cases.
- Planning improved as he recognised that his time could no longer be organised around his former technical duties.
- He changed his communication style and became a valuable participant in senior management meetings.
- He moved from being primarily a colleague and friend to being a manager while preserving good relationships with the team.

Client perspective
What this case shows
Managerial development is most effective when learning is tied to real decisions, deadlines and consequences. The aim is not to replace technical expertise, but to help the person use it from a new organisational role.
