Where is the "value-added"?
Value-added is a critical process component that is missing from most process
flow charts. Graham Process Maps, on the other hand, show every instance
where data is added, deleted or used in an information process, and every
time a part or product is physically altered in a manufacturing process.
Value-added
Value-added in an information flow is new information -- when information is added or changed.
It is displayed in a flow chart with an Add/Alter symbol Add-Alter Symbol
with one exception -- the first time information is entered on
a document an Origination symbol Origination Symbol
is used. The Origination symbol makes it easy to find new items that are created in a process.
You can quickly spot the Origination symbol in the center of the illustration.
Value-added in a manufacturing flow is a physical change to a product that takes it a step closer to
completion. It is represented with a Do symbol Do Symbol
All the other symbols are
Non-value-added steps. Handling operation symbols
handling Symbol
represent doing non-value-added work. These symbols tend to show up more often that any other.
They identify the setup and put away steps in manufacturing processes and
"paper shuffling" in information processes. By the way, keying through database screens,
doing lookups and other electronic activities that don't change the information are all handling steps.
One special type of handling step is found only at the end of a process line. The Destroy symbol
Destroy Symbol represents
an activity that causes the Item to cease to exist. Its purpose is to show
activities of purging and cleansing that are built into a system. There is one Destroy symbol in the illustration.
