*Program Management or programme management is the process of managing several related projects, often with the intention of improving an organization's performance. In practice and in its aims it is often closely related to systems engineering and industrial engineering.
The Program Manager has oversight of the purpose and status of the projects in a program and can use this oversight to support project-level activity to ensure the program goals are met 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. 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.* http://en.wikipedia.org/wiki/Program_management
