The Difference Between Systems Analysis and Systems Design

System analysis and design are about organizing organizations, improving performance as well achieving goals for profit and growth. Emphasis on active systems, the relationship between sub-programs and their contribution to meeting the same purpose.

 Changes in one part of the system were both unexpected and unexpected results in other parts of the system. System authorization is a way of thinking about computer-based software analysis and design. Provides a framework for visualize the organizational and environmental features that work in the system.

Organizations are complex systems that combine communication and coordination underlying systems. computer is introduced to the organization, various functions and inefficiencies performance to user and organization.

Among the positive results are improved performance and a sense of achievement with quality information. Between unintended consequences may be a threat to employee activity, a decrease employee ethics due to engagement and a sense of intimidation by users due to ill it racy. The role of the analyst is to remove such fears and act the program has been successful.

System Analysis and Design

System development can often be thought of as having two major ones.


System Analysis and System Development. System construction is the process of planning a new business plan or to replace or complement an existing plan. System analysis, then, the process of collecting and interpreting facts, diagnostics problems, and use the information to recommend system development.

This is the job of a program analyst. For the better manage its inventory and gain access to some of the latest information about stock levels and to re-order, the store asks the system analyst, to “use the computer” for its stock jobs. Before someone can design a data capture system, review files, and generate reports, one needs to know more about the functioning of the store: what forms are used keep personal details, such as requests, purchase orders, and invoices and more reports are generated and how it is used.

Business System Ideas

The word system is widely used. It has become fashionable to attach a name a program to add current capacity when referring to objects or processes. People are talking exercise program, investment plan, delivery system, information system, education system, computer system etc.

The program can be transferred to any set of components, viz acting in relation to a common cause or purpose.1. A plan must be developed to achieve a predetermined goal.2. Interaction and interdependence should exist between the components.3. The goals of the organization are far more important than ever the objectives of its sub-programs. For example, computer workers applications must comply with the organization’s privacy policy, privacy, and security, as for making selected data (e.g., payment) available from the accounting department on request.

System Features

 Our description of the system suggests some features that are present altogether systems: organization (organization), collaboration, interdependence, integration, and centralization purpose.


 Order means composition and order. Arrangement of parts that helps to achieve goals. In the design of a business plan, for example, the relationship of positions that started with the president at the top led to the bottom the blue-collar workers represent the organizational structure. Such arrangements are displayed system – subsystem relationships, defines the framework of the authorities, clarifies the legitimacy flow of communication, and formally execute a series of commands.


Collaboration refers to the way each part interacts with the other system components. In an organization, for example, shopping should be participatory production, marketing and payroll and staff. Next, the main memory holds the programs and data the arithmetic unit uses for calculation. Communication between these components makes the computer work.

Dependence Interdependence means that parts of an organization or computer are interdependent one another. They are put together and put together in order. One the sub-system relies on the installation of another sub-system to operate efficiently: i.e., Output from one sub-program the input required for another sub-program. This reliance on another is essential for programming work.

In short, no small system can work on its own because it depends on data (input) that it receives from other sub-systems to perform its required functions. Confidence in each other is also reflected in the activities and support of program analysts, program planners, as well as computer-based staff.

The decision to make a computer the app is user-generated, analysed, and designed by the analyst, edited, and is tested by the programmer and operated by a computer operator. None of these people can make goods without the required installation of others in the computer system sub-system.


Integration refers to the completeness of the systems. Synthesis follows analysis for achievement the main purpose of the organization. Integration is about how the system is tied together. It is more than just sharing a visible part or place.

Means parts of the system works together within the system even though each component does something different function. A successful blend will produce a synergistic and dramatic effect total impact than each component works separately.

Main purpose

 The last feature of the system is its main purpose. Objectives may be real or mentioned. While the stated goal may be a realistic one, it is rare an organization to say one goal and then work to achieve another.

A key point that users should know the central purpose of the computer application at the beginning of time Organizational Structure positions of

  • President
  • Vice President
  • Sales Vice President
  • Production Vice President
  • Vice President Finance
  • Department Heads
  • Workers.

President Accounting Head of Department Meeting from the Head Drawing Lines of Authority Employees successful design analysis and modification. Politics and organization reflection often obscures the real purpose. This means that the analyst must work circle these barriers to identify the real purpose of the proposed change.

System Elements In most cases, program analysts work in a dynamic environment where change is taking place it is a way of life. The environment can be a business firm, a business application, or a computer system. To rebuild the system, the following key features must reconsideration.

  • 1. Results and inputs.
  • 2. Processors.
  • 3. Control.
  • 4. Feedback.
  • 5. Environment.
  • 6. Borders and connector visible.

Outputs and Responses The main purpose of the system is to produce a product with value to its user. Whatever the type of exit (goods, services, or information), it must match as expected by the intended user. Inputs are elements (property, person resources, and information) that goes into the system for processing.

Output effect of processing. The system consumes inputs to produce output in the same way as a business brings human, financial, and material resources to produce goods as well services. It is important to point out here that deciding what to output is the first step specifying the type, amount, and frequency of inputs required for system operation.

Because for example, in system analysis, the first concern is to determine user needs for the proposed computer program – that is, the computer output specification is expected to provide for the needs of users.
