Programme management is about managing groups of projects to achieve a desired outcome or benefit for an organisation. It is about the structuring and control of those projects so they deliver effectively as a group.
The Program Manager has oversight of the purpose and status of all projects in a Program and can use this oversight to support project-level activity to ensure the overall program goals are likely to be met, possibly by providing a decision-making capacity that cannot be achieved at project level or by providing the Project Manager with a program perspective when required, or as a sounding board for ideas and approaches to solving project issues that have program impacts.
Typically in a program there is a need to identify and manage cross-project dependencies and often the PMO (Program or Project Management Office) may not have sufficient insight of the risk, issues, requirements, design or solution to be able to usefully manage these.
The Program manager may be well placed to provide this insight by actively seeking out such information from the Project Managers although in large and/or complex projects, a specific role may be required. However this insight arises, the Program Manager needs this in order to be comfortable that the overall program goals are achievable.
