From the Table 3.1, it shows that the start date of each options are the same because this project has been set of “Project Start Date”.
This means the start time should be the same, but the finish date might be different.
Furthermore, option 1.4 has a highest finish date, so this should be eliminated.
From Figure 2.30 (The Gantt Chart of the Project that has been resolved by Option 1.4), Sketching Mock-ups task has been split, so working would not smooth.
As a result, option 1.4 is not a good plan. For the best choice in this assumption, option 1.1 should be chosen if there are compared by the Gantt Chart.
