For the following schedule, assume that for each Job, analysis must be done prior to production, and production completed prior to testing, and testing done prior to installation. Apply the critical chain process assuming that testing is a bottleneck resource (and that the other resources required are not constrained). Use due date as a basis for priority. Apply the critical chain process to schedule, identifying buffers by type:

Use resource buffers before bottleneck resource

Use feeder buffers before interfaces between slack activities and critical activities

Use project buffer

Job	Analysis	Production	Testing	Installation	Due date
A1	4 weeks	4 weeks	4 weeks	2 weeks	Week 15
A2	4 weeks	4 weeks	4 weeks	2 weeks	Week 10
A3	4 weeks	8 weeks	4 weeks	2 weeks	Week 20
