Tracking logic changes can be a nightmare, especially when it comes to large CPM networks with ever changing scope and conditions. Many schedule specifications require that for each logic change, a description for the basis of each change is provided and specifically identifying the affected activities by Activity ID. In other words, the Owner is not just interested in what changed, but more so, why the change was made. Making matters worse, typically each change requires an individual explanation.
Zümmer provides you with seven (7) Comparison Reports designed to neatly account for every logic change between Project Updates.
1&2) Comparison Reports #06/07 – Added/Deleted Logic – These reports list and total the added/deleted logic changes between the Control and Modified Project ID. The reports sort by Predecessor Activity ID.
3) Comparison Report #10 – Added/Deleted Predecessors by Activity ID – groups predecessor logic changes by Activity ID. The action taken, Added or Deleted Predecessor, is coded as AP or DP. The total count is the sum of Reports #06 and #07.
4) Comparison Report – Added/Deleted Successors by Activity ID – is the same as Comparison Report #10 except the action taken, Added or Deleted Successors, is coded as AS or DS. The total count is the same as in Report #10.
5) Comparison Report – Changed Logic By Activity ID – (Illustrated Below) combines the Added/Deleted Successors report with the Added/Deleted Predecessors report. Since every logic change affects activities in pairs (the predecessor and the successor), this report provides an excellent reference document identifying each activity and all the logic changes affecting it.
6&7) Comparison Report – Changed Logic that Increases/Reduces Total Float – Are subsets of Item #5 above.
The Change Logic by Activity ID reports also displays, added/deleted activities, status indicators, and Total Float values.
