1/ Definition
% Respect of due date The indicator measures the amount of work order issued from maintenance plan delayed. The differents levels of delay are :
delay < 1 month; 1 month < delay < 3 months; delay > 3 months.The number of PSS and their impact permit to :
- Check that the feedback and the continuous improvement loop is well done
- Check if the feedback and the continuous improvement loop has a utility
- Verify the impact of the actions taken after the PSS
2/ Objective / Target
It calculates the delay for the portfolio of work orders issued from a maintenance plan and display by duration of delay.
3/ Formula
Number of work orders issued from maintenance plan delayed : ∑ Due date on the notification, or planned date on the call if WO isn't linked to a notification < snapshot extraction date
rate of delay :
- on time: ∑ work orders on time/ ∑ total number of WO
- delay<1 month: ∑ work orders delayed<1 month/ ∑ total number of WO
- 1<delay<3 month: ∑ work orders 1<delayed<3 month/ ∑ total number of WO
- delay>3 months: ∑ work orders delayed>3 months/ ∑ total number of WO
4/ Frequency
Weekly
5/ SAP extraction and detailed calculation
Extraction is based on the calls from the maintenance plans from SAP, the indicator takes the work orders which are not yet executed.
Due date is defined as the required end date on the notification, or as the planned date on the call if the work order isn't linked to a notification
| Field name | From | To | I/E | ||
| No date for order status (GS45, GS50, GS55, 6CMP, CNF) or no reference date on the WO | I | ||||
| Only Work Orders from Maintenance Plan | I | ||||

The goal is to have actions which have an impact on the problems detected thanks to the PSS
An action without impact on an identified problem after a PSS analysis should be record in order to improve the PSS sessions.

5/ Calculation example
This indicator is calculated manually thanks to the excel file below (figure 1).
As a example, Rheinberg decided to create its own calculation rules (see figure 2) which permit to fill the excel file.
Then it's displayed in MECANO (see figure 3).
