Furthermore, the option 2 that has been provided the over working time for the resource.
This option resolves the problem by using the Change Working Time.
This would be a problem if the case study indicates the overtime working cost.
Therefore, the overtime working cost has been assume by using the same rate with normal days (Monday to Friday) ($900 per day for Principal Architect, and $500 per day for Draftsperson).
As a consequence, the cost of project that has been resolved by changing the time is the same as other options.
This solution is divided into 2 options as can be seen in the Table 3.2.
