IT Project Management - Assignment Example Three cells on top, a full width cell in the middle showing Activity name and three cells on bottom. Each of these cells represents important information about the activity as shown below in the picture:- Calculation of Early Start and Early Finish time: Early start time in the first activity is set to 1 whereas duration is given in the requirements. Early finish time is calculated by adding duration in early start time. Early start time of the next sequential activity is set to the previous activity’s early finish time. Adding duration, Early Finish time is found. All activities are traversed in the forward direction and their early start, duration and early finish time is found in this way and written in their respective cells. Early start time of activity that is approached by two or more activities is set to the highest time. For example Activity 14 is approached by Activity 8 which has early finish time as 76 and Activity 12 which has early finish time as 39. The highest early finish time is 76 so early start time of Activity 14 is set to 76. Calculation of Late Start and Late Finish time: Reaching to the end of the activity or finish traversing is restarted in the backward direction. The last activity’s early finish time is set to its late finish time. Deducting duration, late start time is set. Traversing backward previous activity’s late finish time is set to the late start time of the current activity. Then deducting duration, late start time of previous activity is found. All activities are traversed in the backward direction and their late finish, float/slack and late start time is found in this way and written in their respective cells until the start is reached. Late finish time of activity that is approached by two or more activities is set to the lowest time. For example Activity 5 is approached in backward direction by Activity 6 which has late start time as 22 and Activity 7 which has late start time as 65. The lowest early finish time is 22 so late finish time of Activity 5 is set to 22. Calculation of Float or Slack time: The Float or Slack time is the difference between late finish and early finish time. It is same as the difference between early start and late start time. All the activities that have float/slack as zero is critical activity and must be part of the Critical Path. Start and Finish Activity box: Each diagram begins with the start box having values of zero for early start, duration, early finish, late start, float and late finish. Each diagram ends with the finish box having values of maximum days needed to complete for the project. It is set in all the cells of early start, duration, early finish, late start, float late finish. Directional Arrow: Each activity is linked with a directional arrow to show the sequential flow of the activities. The arrow can be in the forward direction to show the progress of work flow or up and down direction to show the parallel works. No backward dire ction is allowed in the network diagram because the time once passed never returns. Task 3: Constraints of Days and Amount Applying constraint of completing project within 70 days has forced to break up two of the activities. Activity 6 of 15 days which has been now changed to Activity 6(a) and Activity 6(b) each of 10 days duration calculated by 2/3*15 formula given in constraints. Similarly Activity 8 of 39 days is now
