| Example 2: Activity has already started |  |
| Activity A has been started, hours have been spent, and a capacity planning has been carried out per project.
Activity duration (project days) | 15
Rough capacity requirement | 200 in work center 10
Actual start date | day 4 week 44 year 92
Hours spent | 30 in work center 10
Detailed capacity requirement | 100 in work center 10
Percentage completed | 20%
The following figure depicts activity A being carried out:
W | Workdays
_ | Non-workdays
p | progress
b | backlog
20 percent of activity A has been completed. In other words, 20 percent of the planned capacity for activity A is ready. Hours to be spent: 0.8 x 200 = 160 hours. Based on the capacity load table, ERP LN computes what percentage of the activity duration has lapsed. The capacity load table shows that 20 percent corresponds to 15 percent of progress in activity duration. This progress is equal to 0.15 x 15 = 2.3 days of the lead time. Planned progress (6 days) is 6/15 x 100% = 40% of the activity duration. The backlog = 6 - 2.3 = 3.7 days. According to the capacity load table, this corresponds to a capacity backlog of 20% = 40 hours. These 40 hours must be added to the remaining lead time of 9 days. Capacity to be utilized according to the original planning: 60% = 120 hours. To achieve the finish date of the activity, extra capacity must be added: 40/120 = 33%. The capacity load per week is then as follows:
Week | Number of days | Percentage of Activity Duration | Capacity Requirement (per Week)
46-92 | 9 | 60% | 0
47-92 | 12 | 80% | 60+20=80
48-92 | 12 | 80% | 0
49-92 | 100% | 100% | 60+20=80
