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.
