Training the individual in Project Management does not prepare the organisation to manage projects better. The training process should place the emphasis on optimising organisational Project Management instead of merely zooming in on the project techniques used by the individual.
Ultimately, the formal knowledge of the individual will become important, and certification training could be helpful in some situations to align the practices of individuals to a common standard. But certification in Project Management does not imply an ability to manage projects. Much of the training available to prospective Project Managers and team members has not been designed to develop them in terms of the human nature of the discipline; nor does it impart the ability to assess a situation contextually in all of its complexity or to take appropriate and decisive action.
Only after the organisation has begun to implement the most important principles and processes and the formal structures required to support them, will the individual have the best insight into the context and practical relevance which such training may offer for the improvement of project planning, monitoring, control and closure.
This process of implementing Project Management must be understood and led by senior management.
