Understanding System Analysis and Design

System analysis is defined as how to understand and specify in detail what should be done by the system. While the system design is defined as explained in detail how the parts and information systems are implemented. Thus, the analysis and design of information systems (ANSI) can be defined as: complex organizational process in which computer-based information systems are implemented. Or it could be summarized as follows:

Analysis: defining the problem.

From requirements to specification.

Design: solve the problem.

From specification to implementation.

There is a key question, why the order of the stages in ANSI becomes very important. There are several specific reasons. First, the success of an information system depends on good analysis and design. Stages of the analysis will determine what should be problem solved on your organization. Errors in this phase will lead to the problem persists even though the information system has been implemented. While the design phase will determine what kind of system will function. Although at this stage of the analysis of the main problems has been mapped correctly, will result in failure of a design error problem solving by computer systems. Thus, these two steps is a crucial step for the development of the system.

Second, the ANSI method is a method long used to build conventional software. Thus, the validity of standard measures that have been tested. This method has also been used extensively in various industries (technology that has been tested).

Third, ANSI offers a new profession as an analyst. In the previous section, we discussed that a responsible stakeholder in the implementation of all phases of the ANSI is an analyst. With the industrial development of the information system is the system analyst and a career in the IT world, offers a lot of fun and challenges, as well as the salaries are not low. And the demand for systems analysts and expertise year after year have also increased. Systems analyst is a challenging profession because it combines many skills such as analytical skills, technical, interpersonal, and managerial. This can be seen and responsibilities of an analyst is based on ANSI approach, which includes:

1. How to build information systems.
2. How to analyze requirements and information systems.
3. How to design a computer-based information systems.
4. How to solve problems within the organization through information systems.
