The paper mainly reflects on the development of the supply chain ERP module for one of the Australian organizations. It is found that with the help of supply chain ERP module, the organization will be able to improve efficiency as well as customer service. In addition to this, the organization will be able to automate the workflow that further assists in reducing the operational costs of the organization. The entire project will be completed within 90 days by utilizing budget of around $100K.
The paper mainly focuses on schedule management plan, work breakdown structure, resource allocation, activity precedence table. In addition to this, the paper also showcases the resource usage within the project.

It is found that there are three types of estimation method that are mainly involved in PERT including optimistic time estimate, most likely time estimate as well as Pessimistic estimation. According to Kerzner and Kerzner (2017), optimistic time estimation is considered as the fastest time in which an activity can be completed whereas Pessimistic time estimation is the maximum time that is generally needed in order to complete an activity. Moreover, most likely time is considered as the fastest time that is needed by an activity of the project to get completed (Serra & Kunc, 2015). The corresponding variance is generally added to each of the project activity of the critical path and the square of variance is considered is the standard deviation of the project. The activity duration table of the project is given below:

Conclusion
It can be concluded that the supply chain ERP module development project is completed successfully within the expected budget and time. It is found that the project faces problem due to overallocation which is mainly resolved with the help of manual procedure. In addition to this, the paper also reflects on the tracking Gantt chart, network diagram and activity precedence table.
