A customer would like to invoke different sets of activities based on criteria derived from input data without changing the parent process model. What is the BEST way to meet this requirement?
Use subprocesses within the parent process.
Use the capability of dynamic assignment of subprocesses via container variables.
Use block activities within the parent process.
Define the process with all possible changes as flows in the parent process |

This sounds suspiciously like a question from the workflow exam.

Hi,
I guess instead of having different sub processes and taking the sub process at run time (this would result in a lot of duplication of modelling effort), i would suggest use the block activity and decide as what activity to give control to based on the transition condition.
Say, there are 3 activities A, B and C. As i can underatsnd from your explanation, the activities that can be given control to can be either just A, or A,B or all A,B and C.
So, you can have a block activity, with a certain exit condition. you can have the count to iterate inside the block as the value in the container. I mean, it is either 1,2 or 3 based on the above scenario.
Appropriately give a transition condition inside the block activity for it to take the correct activity and you are done.

I dont think you can do it. Workflow doesnt allow us to bring a connector back. i mean for 3 activities, you can have A to B ; A to C and B to C; But if you have A to B, then B to A is not possible. So, this option is totally ruled out.
Thanks and Regards,
Supreeth |

| It's a workflow sample test or real test question, so answering such questions is not a good idea. |

Supreeth,
Do u realize the amount of BWU that each block activity requires.
I think the use of the container variables is the easier and better way out.
Regards. |

Hi elvis,
First of all, as vennela has suggested, its not a good idea to answer to this question as it is from a certification exam. But, since we have started it, i thought let us complete it.
I agree with your point but the specification doesnt point towards the need for high speed execution right ?
These are the excerpts from the workflow best practices guide
| Code: |
| Blocks incur an overhead of 0.8 BWU (compared to 3.9 BWU for a subprocess), but can be very effective in process modeling. |
Its always a trade-off between simplicity of modelling , simplicity in maintaining to the performance speed. Blocks can make your whole model look amazingly small. It need not be just used for looping purpose. In case of dynamic routing, which is the requirement, blocks can be very useful. In my previous post, i had given a small example containing 3 activities.
To continue on the same, taking the sub process design, as far as i can understand, your solution is to create sub process for each permutation and combination of the flow. So, for 3 activities you have to have 6 process models. what if the number of activities grow to 10. Look at the complexity involved there as per your design. If you are using block here, you can get off by just having a block activity and catering for all kinds of sequencing and routing. It can even cater for parallel activities being spawned together.
This is purely my personal thought and i would be more than glad to change my mis conception if my understanding is wrong.
Thanks and Regards,
Supreeth |
