Projects are Primarily Social Systems
Leading projects will be most successful if the project managers would realize that projects are social systems.
All project managers and programme managers should develop leadership in leading social systems. When they construct project organizations, they should primary organize people based on their ability to work together and generate synergy.
Using group dynamics rather then technocratic methodologies; projects will successfully produce the right deliverables to all stakeholders. Even better would be that projects are developed as learning systems and provide all stakeholders a challenging learning environment.
Project start up should be organized with all stakeholders, included the project board. You should use group dynamics methodologies like brainstorming to align all visions on the project goals. This will prevent trouble in the final phases when stakeholders will decide if the project goals have been met or not.
When I performed project audits I sadly had to find out that disagreement on goals was the worst problem in reaching goals in budget and time.
