Hello all,
Quick general question. We have an enterprise process model of which the first 4 Program activities will be automated programs written to:
1.) receive XML data into WorkFlow,
2.) determine which of 4 regions the data needs to go to,
3.) determine which of two Business Types the data represent, and
4.) Determine which of many Lines of Business the Data represent.
These 4 steps should be MQ Workflow Program Activities because the activity is simply interpreting data members according to very clear criteria- no human interpretation is involved.
Now once we have determined the Region, Type of Business, and Line of business we need to be able to present the data to a human for complex interpretive steps.
Here's the question: Am I correct in assuming that wherever human interpretation is required these activities should be modeled as a Process Activity in contrast to a Program Activivty?
Thanks,
Jason Greenley |

Not necessarily. But based on what you have said

| complex interpretive steps. |
it looks like the first 4 steps could me automatic program activities.
Then it could be either a sub-process or a block activity with many program activities (as many as the interpretive steps). These program activites could me manual activites.

Hi
In general the decision regarding using Program / Block / Process activity is not based handling type, but on activity usage and structure.
If you have single operation (I understood that in your case it can be manual choosing of output conditions) - in every case you can use Program activity.
Use following parameters which should be defined in Build Time:
executed by User Program Execution Agent;
start - manual
Staff - according your corporate needs
program - create program or JSP which can be called from WEB Client when you start the activity.
Of course, your "manual" handling can be processed via XML messaging. It this case you have automatic synchronized activity which can sent XML message to MQSeries to be processed by your external program with any user interface.
Block activity you need when you have big number of activities in process (to make it readable) or you need create "loop" on more than one activity,
Process activity can be used in same case like Block. Also it can be reusable in different processes. But process creation is very difficult operation and it has impact on performance.
I hope it will helpfully for you.

It is not the 'Human' Vs 'Automatic' activities that determine if you have to use Process or program activity. If the Human in question has to start a Program then you should use a Program activity. If he has to start a SubProcess then you have to model it to be a Process Activity.
If you are using the WebCLient check the option 'Program Activies can be checked out'. This will eliminate the need for a PEA.

It seems to me you think that process activity = automated workflow and program activity = human interruption. That is not correct.
process = one or more pogram activity
program activity can run automatically or require human |
