Performance Monitoring
The performance monitoring functionality is used to analyze the cost progress during processing of a DOP
structure.
Note: To get the most correct graph the actual cost should be calculated every work day for the DOP
structure. This can be done by starting a scheduled job that calculates the actual cost every day for a specific
DOP structure or a specific site.
Dates in the Graph
The time axis shows dates. Starting from the earliest start date of all DOP orders in the DOP structure (or
earliest of start date and actual start date) and ending with the due date for the top DOP order (or latest of
projected due date and due date). When the top DOP order is late, that is, all of the Qty Due is not received into
inventory at due date, the time axis needs to be extended.
Special dates marked in the graph are:
| Date |
Description |
| Start |
The planned start date of the whole DOP structure. |
| Current |
The current date. |
| Plan Due |
The planned due date of the whole DOP structure. |
| P P Due |
Projected planned due date, the projected due date considering longest lead-time left. |
| P C Due |
Projected current due date, the projected due date considering longest lead-time left multiplied by the
time performance rate, (current base line cost/current earned value). |
Cost Parameters in the Graph
The accumulated cost/value axis starts from zero cost and reaches as high as the highest cost in the
diagram.
The diagram shows seven types of cost parameters; Actual Cost, Base Line Cost, Earned Value, Projected
Actual Cost Current Performance, Projected Actual Cost Planned Performance, Projected Earned Value Current
Performance and Projected Earned Value Planned Performance. They are displayed using lines in different
colores in the graph.
- Base Line Cost: The estimated cost each day for the complete DOP structure
- Actual Cost: The actual cost each day for the DOP structure until current date.
- Earned Value: The cost according to the plan of how much we actually have completed at the
moment. The cost is the same as for estimated but with the difference that we calculate only the cost for parts
that are finished at the specific day. If the DOP structure is late, the earned value will be less than the base
line cost.
- Projected Actual Cost Planning Performance: The actual cost for the rest of the days until
the DOP structure is completed. The DOP structure is guessed to be ready from current date plus the longest
branch lead time left to manufacture. The cost will at the end be the current actual cost plus the planned cost
for the remaining DOP orders.
- Projected Actual Cost Current Performance: The actual cost for the rest of the days until
the DOP structure is completed according to current performance. The DOP structure is guessed to be ready from
this date plus the longest branch lead time left to manufacture plus an average difference based on if the
earlier DOP orders are completed on time. (Projected lead-time left = longest branch lead time * performance
rate where performance rate= current base line cost / current earned value). The cost will at the end be the
current actual cost plus the planned cost for the remaining DOP orders plus an average difference based on the
cost difference of earlier completed DOP orders. (Projected cost left = planned cost left * performance rate
where performance rate = current actual cost/ current earned value). If no quantity has been reported the
projected actual cost current performance will not be displayed.
- Projected Earned Value Planning Performance: The earned value for the rest of the days until
the DOP structure is completed. The DOP structure is guessed to be ready from current date plus the longest
branch lead time left to manufacture. The cost will at the end be the current earned value plus the planned cost
for the remaining DOP orders. If the quantity reported is the same as planned, the cost will at the end have the
same value as the Base Line Cost.
- Projected Earned Value Current Performance: The projected earned value for the rest of the
days until the DOP structure is completed according to current performance. The DOP structure is guessed to be
ready from this date plus the longest branch lead time left to manufacture plus an average difference based on if
the earlier DOP orders are completed on time. (Projected lead-time left = longest branch lead time *
performance rate where performance rate= current base line cost / current earned value). The cost will at the
end be the current earned value plus the planned cost for the remaining DOP orders. If the quantity reported is
the same as planned, the cost will at the end have the same value as the Base Line Cost. If no quantity has been
reported the projected earned value current performance will not be displayed.
There are also some defined parameters:
- Required Cost Improvement: This shows how much we must increase the cost performance
compared to the planned cost for the last days until the DOP structure is completed. This is estimated with the
simple factor: ((current actual cost / current earned value)-1)*100. If the current date is after planned
due date the Required Improvement should be zero.
- Actual Inv Dollar Days: This is the integral of the cost build up concerning the actual cost
from actual start date to current date.
- Baseline Inv Dollar Days: This is the integral of the cost build up concerning the base line
cost from planned start date to planned due date.
