Study Notes

Event Decomposition Technique

Identifies use cases by determining business events the system must respond to
Each event corresponds to a use case
Starts with business events to define each use case at the right level of detail
Avoids use cases that are too narrow or too broad

Elementary Business Processes (EBPs)

Most fundamental task in a business process
Performed by one person in one place in response to a business event
Adds measurable business value
Leaves system and its data in a stable and consistent state

Types of Events

External Events: Occur outside the system, initiated by an external agent
Temporal Events: Happen as a result of reaching a point in time (ex: producing a paycheck every two weeks)
State Events (Internal Events): Occur inside the system and trigger processing (ex: inventory dropping below reorder point)

External Events

External agent or actor provides data to or requests data from the system
Examples: Customer placing an order, customer reporting address change

Temporal Events

System generates outputs at defined intervals or when needed
Examples: Payroll system producing paychecks, management receiving performance reports

State Events

Examples: Inventory dropping below reorder point, needing to reorder

Identifying Events

Differentiate events from prior conditions leading up to the event
Focus on events that directly affect the system
Distinguish between external events and system responses
External events should be specific, not just part of a larger interaction

Sequence of Events: Tracing a Transaction’s Life Cycle

Trace the sequence of events for a specific external agent
Identify events that occur throughout a transaction's lifecycle
Example: Customer interaction with a catalog, placing an order, checking order status, changing address, returning items

Technology-Dependent Events and System Controls

Ignore events that are not directly related to users or transactions
These events concern design choices and system controls
Focus on functional requirements during analysis, deferred to design phase

System Control

System controls protect system integrity
Examples: Logging on, backing up data
These controls are important but not typically the focus during analysis

Perfect Technology Assumption

Events are included during analysis only if the system needs to respond under perfect conditions (no equipment failures, unlimited capacity, honest users)
Eliminates events like “Time to back up the database” because technology is assumed to be perfect
System controls are added during design when technology is no longer assumed to be perfect
