Does it mean that your current Lean efforts have no significant impact on project lead times and project completion rate? Even a Lean effort that does not increase any value for customer is muda.
Ideally, in project management I would like to have the following conditions:
There are sufficient resources such that no task needs to wait for resources
There is little or no variation within task durations
There is no uncertainty in the system
No tasks are repeated due to poor quality
Tasks are executed without breaks caused by multitasking
No external factors control the project.
The deviations from these conditions along with task precedence (dependency) relations make project management difficult. Lean can reduce rework and the magnitude and variation of each task duration to some extent but I do not know how it can address the critical function, that is, resource-constrained scheduling subject to natural variation and uncertainty.
