NEED FOR SYSTEMS ANALYSIS AND DESIGN

1 _Systems analysis and design, as performed by systems analysts, seeks to understand what humans

need to analyze data input or data flow systematically, process or transform data, store data, and

output information in the context of a particular business. Furthermore, systems analysis and

design is used to analyze, design, and implement improvements in the support of users and the

5 functioning of businesses that can be accomplished through the use of computerized information

systems.

Installing a system without proper planning leads to great user dissatisfaction and frequently causes

the system to fall into disuse. Systems analysis and design lends structure to the analysis and

design of information systems, a costly endeavor that might otherwise have been done in a

10 haphazard way. It can be thought of as a series of processes systematically undertaken to improve a

business through the use of computerized information systems. Systems analysis and design

involves working with current and eventual users of information systems to support them in

working with technologies in an organizational setting. User involvement throughout the systems

project is critical to the successful development of computerized information systems. Systems

15 analysts, whose roles in the organization are discussed next, are the other essential component in

developing useful information systems.

Users are moving to the forefront as software development teams become more international in

their composition. This means that there is more emphasis on working with software users; on

performing analysis of their business, problems, and objectives; and on communicating the analysis

20 and design of the planned system to all involved.

New technologies also are driving the need for systems analysis. Ajax (Asynchronous JavaScript

and XML) is not a new programming language, but a technique that uses existing languages to

make Web pages function more like a traditional desktop application program. Building and

redesigning Web pages that utilize Ajax technologies will be a task facing analysts. New

25 programming languages, such as Ruby on Rails, which is a combination programming language

and code generator for creating Web applications, will require more analysis.

The systems analyst systematically assesses how users interact with technology and businesses

function by examining the inputting and processing of data and the outputting of information with

the intent of improving organizational processes. Many improvements involve better support of

30 users’ work tasks and business functions through the use of computerized information systems.

This definition emphasizes a systematic, methodical approach to analyzing – and potentially

improving – what is occurring in the specific context experienced by users and created by a

business.

Our definition of a systems analyst is necessarily broad. The analyst must be able to work with

35 people of all descriptions and be experienced in working with computers. The analyst plays many

roles, sometimes balancing several at the same time. The three primary roles of the systems

analyst are consultant, supporting expert, and agent of change.

The systems analyst frequently acts as a systems consultant to humans and their businesses and,

thus, may be hired specifically to address information systems issues within a business. Such

40 hiring can be an advantage because outside consultants can bring with them a fresh perspective

that other people in an organization do not possess. It also means that outside analysts are at a

disadvantage because the true organizational culture can never be known to an outsider.

As an outside consultant, you will rely heavily on the systematic methods discussed throughout this

text to analyze and design appropriate information systems for users working in a particular

45 business. In addition, you will rely on information systems users to help you understand the

organizational culture from others’ viewpoints.
