In the last project that I worked on, a major source of delay for the project came from lack of project resources. Resources which were needed in the second half of the project were promised to the team at the beginning of the project, however when the time came the resource was no longer available. The project progress was significantly slowed down until a replacement was dedicated to the project team. The lesson here was in resource management – making sure that the resources that were promised are still available, and being able to adapt when certain resources are no longer available.
