Internal or external project management?
Updated: 2026-09
Internal project management knows the company and costs less but is often already at capacity and entangled in internal interests. External project management brings experience, independence and method but costs more and needs onboarding. For critical, method-heavy projects the external route pays off.
Who should steer an important IT project — somebody from inside the company or external project management? Both options have clear advantages and drawbacks, and the right choice depends on how critical the work is and what method is required.
Where a formal method such as HERMES is required, or where independence matters, the balance shifts — whereas on smaller internal projects your own person is often the better choice.
Head to head
| Criterion | Internal project management | External project management |
|---|---|---|
| Knowledge of the company | Knows the culture and the systems | Has to get up to speed |
| Cost | Cheaper, often already on the payroll | Higher, but focused |
| Experience | As broad as that person’s own history | Drawn from many projects |
| Independence | Bound into internal interests | Neutral, committed only to the outcome |
| Method | Depends on the person | Method-confident, including HERMES |
When Internal project management wins
- —A smaller project that fits well inside the organisation.
- —There is an experienced, available internal person.
- —Knowledge of the company matters more than method and neutrality.
When External project management wins
- —A critical project with a binding deadline and real risks.
- —A formal method such as HERMES is required.
- —Independence from internal interests matters.
Our take
Our view: where an experienced internal person is available and the project is manageable, internal leadership is cheaper and sensible. As soon as it becomes critical, method-heavy or politically delicate, external project management pays for itself through experience, neutrality and method confidence.
Often the best answer is a combination: external project management that steers the project while drawing in internal knowledge — and builds internal capability rather than replacing it.

External IT project management (HERMES)
External IT project management takes over steering a project from initialisation to closure — following HERMES where the public sector or regulated environments require it. You get leadership, clean documentation and reliable communication without having to fill a position internally.
IT strategy & roadmap
An IT strategy answers which technical investments advance your business goals most — and in what order. The result is a prioritised roadmap that turns a diffuse wish list into an executable plan with clear action areas and milestones.
FAQ
Is external project management not too expensive?
IT projects rarely fail on the technology and often on the steering. The cost of professional project management is usually lower than that of a project that drags.
Does an external lead know our company well enough?
Getting up to speed is part of the engagement. Good external project management draws in internal knowledge deliberately and does not need years of company history to steer effectively.
When is HERMES relevant?
Mainly on public-sector projects or in regulated environments. There, method confidence is a strong argument for external leadership.
