MAN3712 Monitoring and Controlling a Project: Crashing Analysis Report

This assignment focuses on project crashing, a technique used to reduce project duration by increasing resource usage or adding additional resources, which consequently increases project costs. The student analyzes a building project, identifying the critical path and crashing activities to meet a client's deadline of January 2020, while staying within an allocated budget. The analysis includes a detailed table outlining the project's tasks, durations, resources, and costs before and after crashing, along with figures illustrating duration and cost slopes. The report highlights that crashing the project successfully reduces its overall duration, but results in increased costs and resource usage, particularly for tasks on the critical path. The assignment demonstrates the application of project management principles to optimize project timelines and manage resource allocation effectively. The project crashing data shows that the duration is reduced such that the project can be completed within end of January 2020, with an increase in cost by almost $50,000 and the usage of resources have also been increases on some of the tasks that lie on the critical path of the project.

Project Crashing is defined as the process by which the duration of the project is reduced
with some additional costs involved. The most common technique used for project crashing is by
increasing the resource usage in a particular task (Agnetis et al., 2015). With the increase in
resource usage, the total cost usage of that particular resource also increases but the duration of
the task, where the resource usage is increased, decreases. If the increase in resource usage is not
possible but crashing is essential, additional resources are added to the activity such that the
overall duration of the activity is reduced (Harrison & Lock, 2017). However, due to the addition
of resources, the cost of the project also increases.
In this regard, it is to be noted that crashing any activity in the project does not ensure
reduction of duration of the entire project. If the entire project needs to be crashed, only the
activities lying on the critical path of the project need to be crashed (Feylizadeh et al., 2018).
Hence, it is required to identify the critical path first before attempting to crash the project.
For the chosen project, crashing is performed in order to meet the client requirements of
completing the project within January 2020 and the crashed results are shown in the following
table.

In the above table, it is seen that due to the crashing of the project, the duration of the
project is reduced such that the project can be completed within end of January 2020 (Xu, Zhao
& Chen, 2016). However, at the same time, the cost of the project also increases by almost
$50,000 and the usage of resources have also been increases on some of the tasks that lie on the
critical path of the project.
Based on the crashing data, the crash slopes are shown in the following figures.
