Question

You are leading a cross functional team within a large organization and have been asked to put forth an overview of a decomposition model. As you identify the model, you've also been tasked with illustrating a number of aspects of this model can be used to address a failed the workflow process. The failed workflow process has been identified within the inventory and supply department in which the inventory being showed in the system is not what is actually present on the shelves, so to speak.

Business Process Decomposition

IBM Global Business Services (GBS) Service-Oriented Modeling and Architecture (SOMA) is an approach and set of techniques for Business Process Decomposition that bridge the gap between different function in business.

In the figures below, we map the results of process decomposition as SOMA would show it, to the equivalent results in business modeling using business use-case refinement. We include this to show that the two approaches are really only using different terminology and representations for the same concepts, and yield the same result in the end -- a set of business process descriptions that can be used to bridge the gap.

The figure above shows process decomposition into sub-processes and use cases in a notational form used in SOMA. The notion of a sub-process is a convenient construct used to denote further levels of refinement of a process, into its constituent parts (sub-processes), recursively.

Once we get to the point where we begin to look at user-system interactions, we stop and label the sub-process a leaf-level sub-process. A leaf-level sub-process is potentially a composite of system use cases, for example, a leaf-level sub-process of Process Order might have have use-cases of Get Customer Name, Get Customer Address and Get Order Items.

“Here in this case: The failed workflow process has been identified within the inventory and supply department in which the inventory being showed in the system is not what is actually present on the shelves”

While following the decomposition model. The failed workflow process can be rectified by breaking down inventory planning process with input from inventory cycle review process wherein periodic review of physical inventory is being done and difference in physical and system inventory is adjusted before getting as input data for supply planning workflow.
