Modeling For Representation

In addition to analysis as application of modeling ,

modeling is used to represent through the abstraction

process a larger complex scenario in business.

Business when it comes to software development is

viewed as a system for the purpose of understanding ,

analysis and modeling .

Modeling as a method or technique is used to represent

several aspects of customer organization and thebusiness.

The organization model shows a physical picture of

the architecture that conveys the major aspects of

organization ,namely . Control ,communication and

authority structure. The understanding of this aspect of

customer business help in building MIS , where

reporting structure is very important.

Business Organization Model (BOM) A Business Organization Model shows how the

business is organized in terms of functions anddeliverables.

BOM provides a business view in terms of1.Functions

2.Functional Components

3.Responsibility Structure

This view in turn indicates the significance of thefunctions in the business and nature of the business.

Business Organization Model (BOM)

The functional break-up also shows the degree of

important a function has in the organization.

In most cases , it points out which function is driving

the business and where strategic management focus is

essential.

The developer has to understand these functions in the

context of the problem requirements and the

corresponding software solution .

Business Entity Relation Model (BEM)

A business entity relation model shows the position

and relation of entities or objects that are required to

execute a business process.

Example

The entities or objects in the process of converting

customer order to work order are

Information Flow Model (IMF)

Information Flow model is used to understand thesources and destination of information flow, which isrequired to execute the business process.

In IFM , information or data generators and processorsare brought together to explain the flow.

The medium of this could be a document, e-mail orvoice mail.

The contents of the flow could be text , images or

diagrams.

The purpose of the flow is to take the process further toits logical conclusion.

Information Flow Model (IMF)

For example, a customer order is to be processed for

delivery or rejected , and necessary data or information

input has to be provided progressively in the process.

IFM is generally a high level model showing main

flows , internal flows of information from sources such

as a product catalogue, manufacturing schedule.

Customer profile and accounting information are not

shown. These are presumed to be present.

Data Structure Model (DSM)

Data Structure model is important because the datacomplexity decides the architecture, design, testing ,validation and so on.

Let us take a product as an entity whose data structure is to be

understood.ProductA :Name, Model, Price

Product B:Name, Model, specifications by price

specifications, Class of customer, Eligibility

Product

C: Name, Model-1, Model-II, Model-III,

Price by

Model, Packing Instructions, Domestic/Exports

Model I-CKD, Model II-SDK, Model III-

Assembly at site, Set of Spares and accessories

for Model II and Model III.

Data Structure Model (DSM)

The data structure you have realize is highly complexin product C as compared to Product A.

Engineering Bill of Material (BOM) of a product is a

complex structure. Products need definition on number of aspects.

Example : Product

Identification : ID/ Code, Name , Model (s); Versions

The business process due to the nature of complexity incase of product A will be very simple, but in a case ofProduct C it will be very complex due to the varietiesof product, conditions and constraints.
