The roles and duties of IT project management depend greatly on the maturity of other IT processes. For example, if no change management process exists then project management must pick up the slack and, for each project, identify how to move deliverables into production. However, for project managers and project teams, they often do not notice these other processes are missing and they can become frustrated that projects require so much work that seems immaterial to the task at hand: defining access policies, for example, or training the Service Desk. At the same time, the role and expectations of project managers and project teams will vary wildly over time as related processes are developed and improved. Project management maturity is also dependent on other processes: an immature request intake process can limit portfolio managements predictive ability, for example. One way of thinking about project management is it ends up being the process of last resortproject management will get the work done (somehow), even if no other processes exist. Project management is often the first IT management process that departments consciously build, and can be a key source of ideas for process improvement.
