Chapter Supplement: Process Mapping and Analysis
The Process of Process Mapping and Analysis
Determine the desired outcome for the process and the associated metrics needed to evaluate its performance
Using metric to evaluate the
performance of the process
should clearly reflect these
desired outcomes
AHMP: to maximize the percentage of orders going through order entry that are completed within one week from the time that they are received, with 95% being an acceptable level of performance
Identify and bound the critical process
a critical process typically exhibits at least
one of following traits :
1. It is bottleneck process
2. It is visible to the customer
3. It consumes the largest amount of resources
4. It is a shared process
5. It is exhibits the greatest level of variance
6. It is a process that is related to a unique skill or core competency
7. It is the location of the problems/issues of concern to the firm
AHMP: in this case, the critical process is order entry (a shared process). The process starts with the receipt of the order and it ends when the order has entered production scheduling.
Document the existing process (the "current state" map)
Process Activity Types
General guidelines that can make this task simpler and easier to manage:
1. Identify minimum acceptable levels of detail
2. Use different process mapping and analysis techniques
3. Watch out for hidden steps in a process
Three basic charting
1. Process flow table
2. Physical layout diagram
3. Process summary table
Analyse the process and identify oportunities for improvement

Principles of process improvement
Future State Process Flow Table for AHMP
Recommend appropriate changes to the process
(the "future state" map)
Three basic categories
1. Make the change immadiately
2. Postpone the change until sufficient resources or capabilities become available
3. Determine that the change is not ultimately desirable or feasible
Applying in AHMP:
