Business Modeling

Understanding the Complexity of the Environment

• Why build a system at all?
• Where should it be located?
• How can we determine what functionality is
  optimum to locate on a particular node of the
  system?
• When should we use manual steps or workarounds?
• When should we consider restructuring the
  organization itself in order to solve the problem?

The Purpose of Business Modeling

• Understand the structure and dynamics of the
  existing organization
• To ensure that customers, end users, and
  developers have a common understanding of the
  organization
• To understand how to deploy new systems to
  facilitate productivity and which existing
  systems may be affected by the new system

Constructing the Business Model

• Business Use Case Model
• Business use case examples
• Deliver electronic pay stub to employee
• Meet with customer to negotiate contract
• Business actor examples
• Customer
• Employee
• Business Object Model
• Describes entities (departments, paychecks,
  clerk, etc.)
• Specifies how they interact with one another

From the Business Model to the Systems Model

• Business workers will become actors on the system
  we are developing.
• Behaviors described for business workers are
  things that can be automated, so they help us
  find system use cases and define needed
  functionality.
• Business entities are things we may want the
  system to help us maintain, so they help us find
  entity classes in the analysis model of the
  system.

When to Use Business Modeling

• If the application environment is complex and
  multidimensional.
• If many different types of people are involved in
  using the system
