Unit 3: Business Process Re-engineering

3.1 process models notes

Business process

A business process is a collection of activities designed to produce a specific output for a
particular customer or market. It implies a strong emphasis on how the work is done within and
organization, in contrast to a product’s focus on what. A process is thus a specific ordering of
work activities across time and place, with a beginning, an end, and clearly defined inputs and
outputs: a structure for action.

connections

Supply link from object information: A supply link indicates that the information or object linked
to the process is not used up in the processing phase.

Example: Order templates may be used over and over to provide new orders of a certain
style - the templates are not altered or exhausted as part of this activity.
Supply link from object resource: An input link indicates that the attached object or resource is
consumed in the processing procedure. As an example, as customer orders are processed they
are completed and signed off, and typically are used only once per unique resource (order).

Goal link to object goal indicates the attached object to the business process describes the goal of
the process. A goal is the business justification for performing the activity.

Stateflow Link to Object Output

Stateflow link from event indicates some object is passed into a business process. It captures the
passing of control to another entity or process, with the implied passing of state or information
from activity to activity.

goal
A business process has some well defined goal. This is the reason the organization does this
work, and should be defined in terms of the benefits this process has for the organization as a
whole and in satisfying the business needs.
Goal link from activity Business Process indicates the attached object to the business process
describes the goal of the process. A goal is the business justification for performing the activity.
