Critical Chain Project Management Explained

Traditional project management practice expounds the project scheduling based on effort estimation against each individual project activity / task. The tasks are then sequenced based on the interdependencies between them and also based on the availability of resources. Most independent task appears first in the work book. In this approach a task cannot start unit either its parent task is complete or it is a super parent itself or until a resource is available to perform on it. Effort estimate that is used to plan the schedule for each activity usually aggregates both, the time to do the job itself and any safety buffers.
