Ierdahl,
Before you get started, I’d suggest you create a simple process, like making Instant Coffee. And, for each of the modelling techniques described below create a process diagram for making instant coffee..
I’d suggest that you consider a few older processing standard first.
- IDEF0 (1993) is not a bad one to use. Go to http://www.idef.com/idef0.html and download the Idef02.doc (word document). Tis particular modelling technique has its pedigree in DFDs. If you are familiar with Structured Analysis Techniques, you’ll immediately notice the style of context diagrams, decomposing a process, balancing a process etc. IDEF0 teaches you a few things like a process has,
q Inputs (eg. instant coffee, sugar, milk, )
q Controls
q Outputs (eg. Hot coffee)
q Mechanism (eg. Kettle, cups, spoons etc.)
I’d skim read the IDEF documentation.
- Next I’d familiarise my self with DFDs – a dated modelling technique – but a very good one for mapping processes. DFD teaches you a few things like a process has
q Sub-ordinate processes
q Data Flows
q Data stores
There are a few “seasoned” gurus out there, people like Ed Yourdon ,Gane & Sarson and Constantine. Check them out!
- Next, I’d have a read of the UML 2.0 activity diagramming technique. UML teaches you a few things like:
q Process, Activity, Action (Events)
q Process Flows
q Data Flows
q Complex AND, OR, XOR flows
Note: While you read this you’ll notice some IDEF0 concepts
- Next, I’d have a read of the latest BPMN stuff at www.omg.org. Now BPMN will teach you a few things about
q Flow Object
q Connecting Objects
q Swimlanes (Pools and Lanes)
q Artifacts
- Next, I’d have a read about process patterns – why re-invent the wheel when someone has already created one. Process patterns will teach you things like
q Sequential patterns
q Parallel patterns
q All the Van der Aalst Patterns
- Next, we’ll do business process improvements – key assumption here is you already have a process. We’ll do that next time!
Warm regards,
K.
pS. Perhaps those in the forum could present a process chart/diagram for “making instant coffee” – no more than 10 activities, including a start and finish – using what ever technique you are familiar with.
