Sizing the Project Buffer

Putting Buffers in the Project Plan

In building a network diagram or a Gantt chart, treat a project buffer as any other task in the schedule. A buffer, of course, does not consume resources, so doesn’t count toward the resource loading. And unlike a normal task, it shrinks if its predecessor tasks go late, instead of moving its anticipated finish date to the right.

Resource and Cost Buffers

The advantage of schedule buffers is that a certain amount of schedule flexibility, in the forms of float and uncertain estimates, simply appears in the plan. You don’t have to ask management or the customer for it.

When planning the schedule, look for potential flexibility in resources, from people to equipment to money. The best candidates are resources that would otherwise go idle. There’s little or no net cost in using them.
