Need For System Analysis [SAD]

NEED FOR SYSTEMS ANALYSIS AND DESIGN
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.

CONCEPTUAL VIEW OF MIS

The concept is a blend of principles, theories and practices of management, information and system giving rise to a single product called MANAGEMENT INFORMATION SYSTEM . The concept of management gives high regard to the individual and his ability to use the information. MIS gives information through data analysis. While analyzing the information, it relies on many academic disciplines like management science, OR, organization behavior, psychology, etc. The foundation of MIS is the principles of management and its practices. MIS uses the concept of management control in its design and relies heavily on the fact that the decision maker is a human being and is a human processor of information. A MIS can be evolved for a specific objective it is evolved after systematic planning and design. It calls for an analysis of business, management views and policies, organization culture and the management style. The MIS,therefore relies heavily on systems theory.The systems theory offers soluti
