Consideration of Soft Dependencies under Stochastic Uncertainty in Multi-Project Program Implementation

This paper addresses the problems of managing a multi-project program under soft dependencies between some program projects. As a rule, the use of soft dependencies saves the time and/or cost of executing the next project, which decreases the time and/or cost of implementing the entire program. An example shows how rarely dealing with soft dependencies can be reduced to simple schemes without losing the problem essence. Consideration of stochastic uncertainty in project implementation is introduced. According to the conclusion, the effect from considering soft dependencies depends on the probability of realizing them.
