This buffer is placed between the last task and the project completion date as a non-activity buffer and acts as a contingency for the critical chain activities. Any delay on the critical chain will eat this buffer, and the project completion date will not change.

Note that although the critical chain starts at the beginning, it ends before the start of the project buffer and does not end at the project closure. This duration will include any time duration borrowed from the project buffer or exclude the duration added to the buffer.
The critical chain method is one of the most important recent developments in project management. This method addresses many shortcomings of the Critical Path Method, provides a realistic schedule, encourages team members to perform efficiently, and improves productivity.
1)Remove all contingencies from activities. Replace your estimate with an optimistic estimate if you have used a PERT (Program Evaluation and Review Technique) estimate to build the schedule.2)Align the activities with late finish dates and remove resource constraints. Give priority to critical chain activities while assigning resources.3) Add feeding buffers to non-critical chains so that their durations are equal to the critical chain. Add project buffer to the end of the critical chain, but before the project end date.You can see that the Critical Chain Method is a modified form of the Critical Path Method.
I am trying to implement critical chain idea in ms project, I know I need to cut my tasks duration, add buffers, and create schedule on late finish dates. Do you have any example or materials that I can refer to as steps example.
