[Chapter 10] Process Implementation with Executable Models

Question 1

Which are the steps for converting a conceptual model into a executable one?

Answer 1

1) Identify the automation boundaries.
2) Review manual tasks.
3) Complete the process model.
4) Bring the process model to an adequate level of granularity.
5) Specify execution properties.

Question 2

Relative to the 1st step, can all processes be automated? Explain what is the input for the 1st step and the differentiation between types of tasks.

Answer 2

Not all processes can be automated. Which parts can be coordinated by a BPMS, and which parts cannot, in this sense we define the boundaries.
We receive as input a conceptual model of the business process.
Three types of tasks need to be distinguished.
- Automated. Tasks performed by BPMS without human intervening (script with code, service with gears marker if is executed by external application, business rule, send or receive).
- Manual. Tasks performed by participants without any software (hand).
- User. Perform by participants with the help of software (user icon).

Question 3

What is the problem with the 2nd step?

Answer 3

Manual tasks are not visible by the BPMS, does not know them. 2 ways of linking a manual task to a BPMS is implement as user or automated task.

Question 4

What is incomplete in the model in the 3rd step?

Answer 4

• All exceptions need to be handled.
• Conceptual models do not specify the data types and how data is being used.
