Introduction
|
The Process Structure Diagram (PSD) is a tool to present processes and algorithms in a structured and graphical way.
A PSD is characterized by its high level of structure. The integrity of process described in a PSD high. Therefore the PSD is a powerful tool to support the design of processes.
By its nature, the PSD also visualises the relation between several (sub)processes and thus allows the design of multi-process systems.
An other name for PSD is Nassi-Schneider diagram.

Why should we use PSD?
|
Benefits of using the PSD are:
-
high level of structure
-
complex processes visualized in a simple diagram
-
easy to understand
-
PSD shows gaps in an existing process
-
by simulating a new process with PSD mistakes are discovered early in the design stage
-
within a PSD other PSDs can be started without losing overview
-
of each PSD only one version exists: when a PSD is changed or updated these changes are applied directly to all processes where this PSD is used
-
not only a graphical tool but also a powerful design tool

When should we use PSD
|
1. After Makigami process analysis
2. After Value Added Activity Analysis
3. “Greenfield”, when designing a new process

|
What does it look like?
|
In a very compact way the PSD describes a complete (business)process. Here an example of an order-intake process
