The feeding buffer(s) are occasionally penetrated because:
- Exepron is a business tool aimed at maximizing Throughput. For a portfolio of Projects, this means Exepron CCPM calculates the shortest possible duration for each project. This solution will compact the Total Portfolio into the shortest possible time frame.
- Exepron’s unique assertive one-pass scheduling approach will not permit gaps in the Critical Chain. This assertive approach may result in the penetration of some of the Feeding Buffers.
Exepron’s intelligent one-pass shortest scheduling algorithm saves the user the tedious iterative discovery of the shortest possible CCPM schedule. This assertive scheduling approach to compact the CCPM schedule can cause pre-penetration of some Feeding Buffers. If excessive buffer penetration makes the project’s risk level unacceptably high, assign additional resources and look for opportunities to schedule more tasks in parallel.
Further notes:
- Exepron will not schedule a Feeding Task to start before the first Critical Chain Task; this can also contribute to Feeding Buffer penetration.
- Feeding Buffer penetration can also occur when the scheduling algorithm resolves a Resource contention while maintaining the integrity of Task dependencies.
- An acceptable Project Risk Quotient (PRQ) is keeping the PRQ below 0.40 when planning a project.
