A project without a clear methodology usually doesn't fail from lack of effort, but from an unclear scope, a missing risk owner, or uncontrolled changes to the brief.
When setting up a project management office (PMO), needing an external project manager, or when a company runs several projects at once and lacks visibility into how they compete for resources.
We manage projects using the PRINCE2 methodology (Foundation certified) — with a clearly defined scope, risk management and regular reporting. Where the environment calls for it, we combine PRINCE2 with an agile approach (AgileSHIFT).
