please answer question 2

Other managers take a more aggressive approach to managing slack within the schedule. They use an early start schedule and prohibit use of slack on any activity or work package to be used unless authorised by the project manager. Progress by percent complete and by remaining time is carefully monitored. Activities that are beating estimated completion times are reported so that succeeding activities can start earlier and time is not wasted. The overall intent is to create and save slack as a time buffer to complete the project early or to cover delay problems that may creep up on critical activities or paths."

Elucidate (using relevant diagrams) the differences between a project that has a fixed delivery day and one that has a fixed limit on resource usage. Question 2 (30 Marks) The above extract discusses various strategies for accelerating the completion of projects especially on resource-limited projects. Critically discuss how the alternative method for project completion acceleration (Critical Chain Project Management scheduling method) can help solve the management of slack on resource-limited projects.
