The Fuse Logic Index is a cloud-based metric library that gives insight into the logic quality of a schedule. Logic is viewed as one of the most important underpinnings of a schedule.
Fuse Logic Index Metrics
The Fuse Logic Index metrics provide insight into the logic quality of a schedule.
| Field/Option | Description |
|---|
| Redundancy Index
|
A redundant, or unnecessary logic link, is a link between two activities made redundant by an additional, often more complex, logic link between the same two activities. A high Redundancy Index is a sign of an overly complex schedule which should be simplified.
|
| Open Ends
|
A high number of activities missing a predecessor, a successor, or both, signals a poorly developed plan. This number should be less than 5% of the schedule.
|
| Open Starts
|
If the start of the successor activity is left open, with the predecessor activity tied to the finish of the successor, the result is an open start or "dangling activity."
|
| Open Finishes
|
If the finish of the predecessor activity is left open, with the predecessor tied by its start to the successor, the result is an open finish or "dangling activity."
|
| Leads
|
A lead, also known as a negative lag, is often used to adjust the successor start or end date relative to the logic link applied. This is not good practice as it can result in the successor starting before the start of the predecessor.
|
| Lags
|
A lag is a duration applied to a logic link often used to represent non-working time between activities, for example, concrete curing. Lags tend to hide detail within the schedule and cannot be statused like normal activities; therefore, they should be converted to actual activities with durations.
|
| SF Links
|
A high number of SF links is not indicative of a well-developed plan.
