Characteristics of e-business DevelopmentAn e-business development project has many characteristics in common withthe development of any complex information system. These characteristicstypically include: • Externally imposed rules and regulations, often of high complexity, such as business

rules.

• High complexity in data structures.

• Customer focus.

• Pressed time schedules.

• Performance and reliability of the final system is a primary concern.

Typical differences in an e-business development project are:• More emphasis on business modeling.

• More emphasis on user-interface design.

• Use of e-business enabling technologies to define the architecture.

• A greater focus on performance testing.

Business Modeling?

Encompasses all modeling techniques you can use to visually model a business.

These are an essential subset of the techniques you may use to perform business engineering.

Visualization is essential for understanding and contemplation.

What Should Business Models Show?

Customers

Business processes

Goals

Organizational structure

Roles and responsibilities

Products

Internal deliverables

Business Use-Case ModelBusiness actor -

represents a role played in relation to the business by someone or something.

Business use case - a sequence of actions performed in a business that produces a result of observable value to an individual actor of the business.

Business Use-Case Model – Business Goals

A requirement that must be satisfied by the business

Measurable, at least at the lowest level of the goal hierarchy

Business Analysis Model

Is visualized byDynamic diagrams – the activity diagram and statechart diagramStatic diagrams – the class diagramInteractive diagrams – the collaboration diagram or sequence diagram

Business Analysis Model - Business Entities

Showing products, deliverables, consumables

A "thing" handled or used by business workers

Sales Person Product SpecialistSolution Owner

Business Analysis Model - Business Workers

Showing roles and responsibilities

A role or set of roles in the business

A business worker interacts with other workers and manipulates business entities to participate in the realization of a business use-case

Can be human or non-human

Business Events

A significant occurrence in the activities of the business that requires immediate action

Business Analysis Model - Business Use-case Realizations

There are many business workers and business entities

Business use-case realizations help us find the right ones

Business use-case realizations help us organize them

Business Analysis Model – Business Systems

Encapsulates a set of roles and resources that together fulfill a specific purpose

Represent an independent capability within a business

Have interfaces, which represent services that can be provided

Contains people, hardware, and software

What Is Different ?

Business modeling in the RUP does not prescribe functional decomposition or workflow breakdown

Uses the Unified Modeling Language

UML business modeling supports an iterative and incremental lifecycleNo other technique allows you to effectively model partial purpose,

process, structure and behavior all at the same time and yet still maintain a bird's eye-view

Functional decompositioning is the breaking down of a problem in to small parts. The context for one part is difficult to comprehend.

The Advantage

A straightforward trace from business models to systems

Supports iterative business modeling

Emphasizes roles before workflow – a more intuitive way of defining business processes

Consistent terminology and approach to software development – a common language throughout the organization

OO gives small semantic gap between classes & objects in the model and phenomena in the real world
