In Chapter 3, Leach introduces the concept of a project buffer, a tool that adds an allowance at the end of the critical chain to increase the probability of on-time delivery (p. 58). He describes some different ideas about how to size the buffer, referencing several ideas about how to a realistic level of predictability while avoiding sources of bias in the estimation.
For those of us with PM experience: What sort of project buffers do you currently use and how do you determine them? What experiences have led you to use that particular buffer?
For those of us without PM experience: How do you see the concept of a project buffer applying itself to projects in your workplace? Would a buffer offer you anything additional to your project, something that float (slack) doesn’t offer?
