Answer

System development can generally be thought of having two major components: systems analysis and systems design.In System Analysis more emphasis is given to understanding the details of an existing system or a proposed one and then deciding whether the proposed system is desirable or not and whether the existing system needs improvements. Thus, system analysis is the process of investigating a system, identifying problems, and using the information to recommend improvements to the system.

"System" in system analysis and system design can mean any system whatsoever. Examples include computer systems, human processes, businesses, and the likes. It is any process or entity that can be analyzed or designed.

The Monster theorem is used to study analysis and design of algorithm. The study of analysis and design of algorithm is very important as it helps the learners develop the ability to analyze the complexity of the programs.

The objectives are to determine specific needs of a system and ultimately facilitate a comprehensive design around these needs.

describe different life cycle models and explain the contribution of the system analysis and design within them;

discuss various approaches to systems analysis and design and explain their strengths and weaknesses;

evaluate the tools and techniques of systems analysis and design that may be used in a given context;

use appropriate methods and techniques to produce an analysis of a given scenario;

use appropriate methods and techniques to produce a system design for an given scenario;

provide suitable documentation for systems analysis and design activities

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

code generator for creating Web applications, will require more analysis

Systems analysis is used when designing a new computer system to replace a manual system or an older computer system. In order to design it, it is essential to know how the current system works, so that the new system will do all that the current system does and possibly find ways of improving it further.

Without understanding those fields a programmer can't communicate with the systems engineers and design engineers and will likely write incorrect code that someone will have to fix.
