Flow is a criterion according to which the one place within the possible solution space is chosen,
which is “most retarding”.
Effective investments – quick benefit.

Principles of TOC based PPPM
•The agent focuses on the very one task, he/she/it is running.
•The agent reports accomplishing of the task and hands over “the baton”.
•Actions start not before the constraint permits it.
•“Rope and Drum” principle. Work rhythm.

Rope and Drum Principle
•The work must not be pushed through a team of agents !
•The work must be pulled through a team of agents !
•The work must be done in a regular rhythm !

What projects in one group mutually shares?
What are they pass on?
Decide on priorities
What to do with a situation:
one project affects the other projects?

REDUCE MULTITASKING
OF CRITICAL RESOURCES!!
Remember the Discussion:
•What is a constraint in a Program or Portfolio of Projects?
–What makes the greatest troubles?
–What constraints to realize the project in shorter time and for less money?

24
Discussion
•What other is a constraint in a Program or Portfolio of Projects?
•Do you think “milestones” will help us ?!?
•Do you know what consequences follow from milestones setting ?
•Do you know what is a “critical path” ? (If not, then learn !!)
•Is the critical path enough for planning and realization of projects within a Program or Portfolio
?

Critical Chain
•Critical Chain is such sequence of depended activities from various projects of a program or a
portfolio, which constraints to finish a project or a set of projects early, with the same set of
resources.
