Objectives

• Understand some approaches to analyze
  requirements of e-Business solution.
• Know some key elements of techniques to provide
  blueprint design for the e-Business solution.

Contents

• Intro
• Analysis for e-Business
• Process modeling
• Data modeling
• Design for e-Business

4
Intro

• General understanding of analysis design
• Analysis platform-independent approach to elicit
  what are the requirements of systems
  business-process or users.
• Design platform-dependent models as guidance to
  develop final system solution.
• Analysis design identifying and structuring of
  system requirements to be able to create the
  plan/blueprint of e-business solution effectively
  efficiently.
• Role to convert strategic planning into final
  implementation of system solution.

5
Analysis for e-business

• Analysis for e-business understanding the
  business and user requirements for e-business
  system by
• Understanding the current business process
• Reviewing possible alternatives for implementing
  e-business solution
• Role used as a tool to optimize the flow of
  information both inside and outside organization.
• Commonly used tools
• Workflow management (WFM)
• Process modeling (PM)
• Data modeling (DM)

6
Workflow management

• WFM the automation of a business process, in a
  whole or part during which documents, information
  or task are passed from one participant to
  another for action, according to a set of
  procedural rules.
• Criteria in performing WFM
• As soon as possible
• By the right entity
• In the right order
• Purpose
• Assign task to people/entity
• Remind people about their tasks
• Allow collaboration between people/entity
• Retrieve information needed to perform task
• Provide report to management about task status
  organization performance

7
Process modeling

• Using hierarchical method of
• The processes and its constituent sub-processes
• The dependencies between processes
• The inputs and outputs of processes
• Activity-based process definition analysis tools
  used to identify the relationship between tasks
  within business process.
• Process part of a system that has a clearly
  defined purpose or objective as well as clearly
  defined inputs outputs.
• Process mapping identification of location and
  responsibility of process within organization
• Purpose to eliminate the overlapping of
  functional area

8
Example of process mapping
9
Task analysis decomposition

• Task Analysis identification of a group of task,
  their sequence and how they are broken down.
• Curtis 1995 provides a useful framework of task
  analysis decomposition as follow
• Level 1 Business Process
• Level 2 Activities
• Level 3 Task
• Level 4 Sub-task
• Business process a set of one or more linked
  procedure or activities which collectively
  realize a business objective.
• Activity a collection of work that forms one
  logical step within a process.
• Task (Work item) representation of the work to
  be processed in the context of an activity within
  a process instance.

Example of task analysis
11
Flow process chart

• FPC tools for describing the sequence of
  activities of a workflow that is a part of a
  business process
• Symbols used

Data modeling

• Data modeling for e-Business e-Commerce system
  solution is referred to relational database
  analysis in information system management
• Entity Relationship Diagram
• Normalization
• Critical step in developing them
• Identifying entities
• Identifying attributes for entities
• Identifying relationships its properties among
  them
• Things to be remembered
• Entity
• Attribute (primary key, secondary key)
• Record
• Relationship

21
Example of data modeling
22
Design for e-Business

• Architectural design of e-Business system
• Client/server model system architecture in which
  end-user machine is known as client run
  application while accessing data and program from
  server
• Typical function in client/server model
• Data storage
• Query processing
• Display/Interface ? the most prominent
• Application logic
• Three-tier client/server model the first tier is
  the client that handles display, the second is
  application logic business rules, the third is
  database storage.

23
Display/interface

• Display/interface is the front-line of e-business
  e-commerce system solution to the users.
• It varies in term of
• Structure
• Presentation
• Behavior
• Display/interface implements hypertext scheme.
• Navigation refers to paging structure and process
  flow among system display. It also reflects
  system solution functionality derived from its
  business use-cases.
