VirtualWorks: Solutioning

• Solutioning

– is business process driven. A Business process is modeled as a set of business functions

– establishes the scope of the solution to be developed by capturing the processes relevant to the customer

– maps to the Requirements Engineering Process of the software development life cycle

Prepare Blueprint :ConceptsBusiness Function• A business process is broken down as a

set of functions• Functions map to components• Examples

– Leave Management• Leave Master Setup• Leave Maintenance• Leave Encashment

– Training• Scheduling• Nominations• Training Record Maintenance• Training Resource Master

Prepare Blueprint :ConceptsActivity• Business Functions are carried out as a sequence of smaller atomic pieces

of work called Activities that transform the business function from one consistent state to another

• Activities are user entry points into the system• The flow of activities defines the workflow

• Example – Leave Maintenance(Function)

• Leave Application• Leave Authorization• Leave Alteration• Leave Balance Enquiry

Prepare Blueprint :Concepts

User Interface (UI)

• An Activity is implemented as one or more User Interfaces

• The flow across User interfaces establishes traversal

Prepare Blueprint :Concepts

Actions (Tasks)

• Actions are steps performed by a user on a UI to complete the activity

Prepare Blueprint :Concepts

Business Rules

• Business rules represent the flow of steps to complete an action

• They are termed as Flow Business Rules

Business Process Modeling

Business Process Modeling – Our Approach

Business Process Modeling

Business Process Modeling

Process Modeling is done at two levels:

• Process Flow – Entry and Exit events for the functions of a

business process are identified

• Activity Flow– Entry and Exit events for the activities of a

function, are identified

Business Process Modeling• Event

– a real world happening or occurrence of importance to the business entity/ process/ function

– a stimulus that causes a function to be triggered (entry event)

– an outcome of a function (exit event)

• Business process may be represented as a set of logically connected functions and real world events

Events

Business Process Modeling An event has two characteristics

• Flow Type

– External– Transfer of Control– Information exchange

• Event Sequence

– Start– Intermediate– End

Business Process Modeling

• Event Flow

• External events (EXT) – events which enter from or exit into the external

world – External world includes external systems

ExamplesAn order placed across a counter

Invoice printing triggered to a printer

Business Process Modeling

• Event Flow

• Transfer of Control events (TR)– events, which hand over control to another

function or activity

– ExamplesItems selected, handed over to packaging function

Complaints received, assigned to Call processing from Call logging

Business Process Modeling

• Event Flow

• Information Exchange events (IE)– events, which facilitate transfer of information

across functions

Examples

Checking vendor rating for purchase order

creation

Business Process Modeling

• Event Sequence

• Start events (ST)– entry events, which trigger a business

function or activity

ExampleSale order received

Business Process Modeling

• Event Sequence

• Intermediate events (IN)– events across two functions or activities for

information exchange or transfer of control

ExampleItem availability to be checked

Purchase order to be authorized

Business Process Modeling

• Event Sequence

• End events (ED)– exit events to the external world or to another

business process/function on completion of the required action

ExampleStock update from production process

Business Process Modeling

• Business Process Modeling tool

– The ARIS, Event-driven Process Chain (EPC) model is used to represent the business process as a chain of functions and events

– The EPC model consists of Events and Functions

– Custom scripts have been used for modeling

Conventions for process modeling

• The Event symbol is used to represent the events in a business process

• The Function symbol is used to represent the

– Business functions at the Process Flow level, – Activities at the Activity Flow level
