Information System Analysis Methodologies

What is information system analysis? According to Merriam Webster it is “a process of discovering how something works or how it can be better or how something can be utilized to accomplish a specific purpose”. So, information system analysis is the process of studying an organizational process or a system to identify its purpose and objectives and develop systems and methods so that they will efficiently accomplish those purposes. It is used in all areas of organizations and businesses.

Information systems analysis plays an important role in project management. In this process an individual or team conducts an analysis of the current information system, its value, its usability and its suitability for a given project. Data sources are gathered and analyzed so as to provide information that is relevant to the project. Project managers then choose the right information system for a given project. The main objective of an information system analysis is to find out what needs the organization has and how they can be met through the use of that information system.

An information system analysis also involves the development of a lifecycle chart. This includes five phases: Design, development, service, operation and maintenance. In the design phase, requirements are identified and a user concept is developed. It is then analyzed for its security, reliability, scalability, robustness and flexibility. At this stage, requirements may still be under negotiation. The lifecycle chart shows the relationship between each phase and when it is due to be completed.

In information systems development, requirements are analyzed for their technical and economic validity. Then the designing and developing phases of the process are conducted. These phases are critical for information system development. Once the designing and developing phases are complete, then it is time to test the systems. When the testing is successful, a new system is designed and developed according to the testing results.

A valuable candidate methodology is the mixture of both qualitative and quantitative approaches. Soil quality plays an important role in information system analysis practice. By determining the condition of the soils, it helps determine the quality of the information systems, software and hardware. The soil analysis report helps the managers in deciding whether to continue with the project or to move on to the next phase of the project.

One of the most important things to note is that an information systems development project is not just about collecting information. It is also about how one uses that information to meet the organizational objectives. The different phases in information system analysis help in determining the requirements for each process. The different stages of information systems development help in determining the requirements for hardware, application software and database development. These phases also help in determining the requirements for networks, desktop systems, web services, desktop environment, server and storage environment. Soil quality assessment of environmental impact forms an important part of any information system analysis practice.

According to many information system analysis practitioners, a deep awareness of users and its activities is a prerequisite for information system analysis practice. Users are the users and they are responsible for the system’s success. Therefore, information system analysts must have a deep understanding of users’ needs and aspirations.

The information system analysis methodologies used are designed to help managers build a technology platform that is robust, scalable, flexible, and innovative. The methodology helps in achieving this goal. The basis of any such methodology is dependent upon a thorough understanding of the IT environment. Soil quality, physical and logical constraints, economic factors, engineering considerations are some of the important factors considered.
