1) A BUSINESS SYSTEM OPTIONS (BSOS) FOR THE ORGANIZATIONWHICH INCLUDED

Introduction

Options Considered

Conclusion

This is the Business System Option (BSOs) for the KPM Seri Iskandar which is System Parking

INTRODUCTION

As KPM Seri Iskandar is a college, also make a manual system parking. This college had uses

many information system to manage the college. So, KPM Seri Iskandar must know which the

additional information system that suitable to apply in the college. KPM Seri Iskandar should

take a note about the implementation efforts, time resources, user impacts and risks involved ifthey apply that system.

Below is the option that the KPM Seri Iskandar should be considered based on the system that

had been suggested.

BUSINESS SYSTEM OPTIONS CONSIDERED.

Below is the Business System Option that KPM Seri Iskandar should be considered.

A. Enhance the existing system in both technical areas and business

functionality.

Enhance the existing system for the technical system by upgrade the software and hardware.

This is for the enhancement of the business needs and strategy. As the KPM Seri Iskandar does

not have a systematic parking and the signboard parking, they should make a change in this

problem.

C.Develop a new business.

This is about to re-design a new system with the business functionality and the workflow totally

different from the existing system. KPM Seri Iskandar still uses a manual system parking which

is traditional method to recognize the car enter and out in college. This is not good for the KPM

Seri Iskandar to have the manual system parking. So KPM Seri Iskandar should change this

manual method to the system method by using systematic parking system.

D. Do Nothing.

This is about no changes from the existing system. KPM Seri Iskandar never make a change

about the problem such as provide signboard and space parking for all students such as hostel

siswa and siswi

In order to select an option solution of the system, KPM Seri Iskandar should consider for its

benefits, impact and technical.

OPTION A: Enhance the existing system in both technical areas and business

functionality.

In this option, existing system will be enhances including the hardware, software and technical.

This is to meet the technical enhancement. Besides that, the new business requirement

currently not available from the system will be met and some of the business function will be

modified during the technical enhancement process. so, by using the Customer Relationship

Management software, the company can know what is the customer need and wants while

meets the business environment.

There are the advantages by using this option:

The outdated hardware and software will be updated to the currently technology.

The new system is easy to learn. This is because the existing business functional and

workflow is unchanged.

The new business requirement can be supported.

The new business requirement for the system can be built based on the existing

business.

There are also the disadvantages of using this option:

In order to meet the new business needs, longer system design and development time

will be required.

OPTION C: Develop a new business.

This option is about to re-develop a new system from the business functionality and workflow

which is totally different from the existing system. This system will cover the existing system

and also the business requirements. Not only that, the technical environment also will beconducted. The technical enhancement is including the enhancement of the software and

hardware.

There are advantages by using this:

The whole system in the business will be re-built. This is means, the overall business

system will not be constrained by the existing system.

The outdated hardware and software will be updated to the currently technology.

The new business requirement can be supported.

The technical upgrade and will meet the future interface system.

There are also the disadvantages of the system:

To time needed to re-design the business system could be longer.

Business flow will be re-design and all the existing system business function need to be

re-developed.

The new system will be quite difficult to learn as the workflow and the business system

is different from the existing system.

OPTION D: Do Nothing.

This option is means that there are no changes in the business system to be made.

2) DATA FLOW DIAGRAM OF THE PROPOSED NEW SYSTEM SHOWINGENTITIES, PROCESSES, DATA STORES AND INFORMATION FLOWS.

According to the (Kozar, 1997) , it states the definition of the Data Flow Diagram, Data FlowDiagramming is a means of representing a system at any level of detail with a graphic network

of symbols showing data flows, data stores, data processes, and data sources/destinations.

DFD is use to show the flow of data in an information system. This diagram uses symbol with

different shapes to indicate how the data flows in the system. Below is the symbols used in the

Data Flow Diagram (DFD).

Symbols Name Function

Process Any steps that involves

manipulating data

External Entity

A person, organization or

another system that sends

input (data sources) or

receives output data (data

destination).

Data Store

A collection of data kept by

the system in any form, such

as in a file or database.

Data Flow Direction of the data flow.

1) AN ENTITY RELATIONSHIP DIAGRAM OF THE BUSINESS

According to the (Webopedia, 2013) , it stated that entity-relationship (ER) diagram , a graphical

representation of entities and their relationships to each other, typically used in computing in

regard to the organization of data within databases or information systems. An entity is a piece

of data-an object or concept about which data is stored. A relationship is how the data is shared

between entities.

Under the Entity Relationship Diagram, there are three types of cardinalities which is one to one

(1:1), one to many (1:M), and many to many(M:M).

According to the (Webopedia, 2013), it states the definition of the each cardinalities.

one-to-one (1:1) : one instance of an entity (A) is associated with one other instance of

another entity (B). For example, in a database of employees, each employee name (A) is

associated with only one social security number (B).

one-to-many (1:M) : one instance of an entity (A) is associated with zero, one or many

instances of another entity (B), but for one instance of entity B there is only one instance of

entity A. For example, for a company with all employees working in one building, the building

name (A) is associated with many different employees (B), but those employees all share the

same singular association with entity A.

many-to-many (M:M) : one instance of an entity (A) is associated with one, zero or many

instances of another entity (B), and one instance of entity B is associated with one, zero or

many instances of entity A. For example, for a company in which all of its employees work on

multiple projects, each instance of an employee (A) is associated with many instances of a

project (B), and at the same time, each instance of a project (B) has multiple employees (A)

associated with it.

Usually, system analyst will uses ERD to show the design of a database and it is basically about

the relationship between entities in the database. An entity is something about which data is

stored in a database, such as customers, products, an item in inventory or an order.
