💡 Why was a particular activity delayed to finish? You can now significantly accelerate the tedious workflow required to answer this question in multi-thousand activity schedules.

How does Delay Analysis work?

The tool inspects the specified activity and start going backwards predecessor by predecessor throughout the activity network. Required information and data are calculated whilst that backward pass takes place (ie the start delay of the activities, their possible timespan increase, how much delay they are transferring to their successors etc).

Understand which activities show in the canvas

Activities that meet the criteria listed below are displayed in the delay analysis canvas as cards.

Activities that exist within the illustrated delay attribution network but do not satisfy the following criteria can be found by opening the intermediate paths pop up.

Float = 0 in Selected Schedule
OR
Float = 0 in Baseline Schedule
OR
Transmitted Delay > 0 in Selected Schedule
AND
Working days Increase or Non-working days Increase or Non Inherited Start delay > 0
AND
Following relationship = FF OR FS

Deciding the contribution on your own

Our own algorithm created by our scientists reads the data and calculates delay contribution for each activity in Contribution Mode. However, since there are a lot of intricacies in legal frameworks across countries, we also offer you the raw data in Dates mode for the experts to decide themselves.

How does the delay contribution assignment happen?

An activity gets assigned delay contribution when it transmits delay in addition to it having either a duration increase, non-inherited start delay or both. The delay contribution that that an activity gets is analogous with the proportion of the delay it transmits to its successor/s compared to other activities that also transmit delay to those successor/s. After all calculations are complete, the contribution of all the activities is normalised to add up to 100%.

Highlighting the Activity codes

You can also filter the activities in the graph based on their Activity codes to see which of your suppliers, activities, or contractors have the most delay contributions.

Examples

Scenario 1

Activity X has a Total Delay of 10 days (Finish Delay). This delay is affected by Activity A’s transmitted delay to Activity X and its own Timespan Change.

Scenario 2

Activity X has a Total Delay of 10 days (Finish Delay). This delay is affected by Activity A’s transmitted delay to Activity X and its own Timespan Change.
