Although every project team will develop a culture, not every culture that develops is good. Ideally, team members will work together and thus create a cooperative environment where communications and teamwork create synergy among the team members that enhances the team's effectiveness. Contrariwise, if the team members do not communicate effectively, isolate themselves in tasks, and work for their own interests, a pathological team culture develops that can result in project delays and even failure.
Although each team member initially contributes to the project team culture, other factors also influence it which may be beyond the project manager's control. Teams where too many polices are in place, too much paperwork is required, and too much bureaucracy is in place, and too many meetings are held will tend to generate negative cultures.
Because many factors that negatively impact the culture of a team are systemic, the quality of the project team culture can be in the hands of senior management and executives who may or may not understand the concept of project management. Companies that do not value the principles of project management or those that are not committed to it are those that are most likely to impose too many rules and requirements on the team without regard to their effects.
