Constraint-Based Multi-Project Management:
Leveraging Project Resources
To Complete More Projects Faster


Strategy and Tactics Tree (S&T):
This is the fastest, most effective way that we have found to drive bottom line results. Why?

  • Management agrees, as the first step in the strategy, on the amount of focus needed right now to drive results.
  • Management is aligned cross-functionally. The detailed steps (tactics) that each function must take at each level, and the intermediate results (strategy) expected, are clearly laid out. All the interdependencies are connected between functions and down levels of the organization, to provide a comprehensive answer.
  • Assumptions are stated and examined for both strategy and tactics. Every senior management team member, through any level desired, can scrutinize assumptions to prevent costly errors or to speed up the process.
