Project Management Book of Knowledge goes into a lot of techniques, such as activity sequencing, contract types, change control, etc. One has to understand that these are guidelines and operating framework. Tools such as Microsoft Project and Microsoft SharePoint have addressed a number of these requirements in their software to do resource leveling, critical path analysis, multi-project dependency, document sharing, team collaboration, etc.
But, the tools don't build credibility for project manager. Think of a project manager that updated the tasks in the Project Plan but failed to provide unambiguous direction to the team or failed to elevate to the management the increasing scope from a client? Will tools address these issues?
