Methodology 

An Information Systems Methodology is a methodical approach to information systems planning analysis and design. 

Without planning most of the information systems will remain poorly organised and ill equipped to meet the objectives of their service to the user. Without a clear definition of their roles information systems will be unable to obtain the essential support and resources from the authorities. 

The essential features of planning are: 

  1. It gives direction to the growth and complexity of the system.  
  2. Minimises ad hoc decisions. It provides a basic frame work for service. 

The advantages of planning are: 

  1. It helps to systematically move towards the achievement of the goals of an information system. 
  2. It helps in identifying and differentiating priority actions to achieve specified goals. 
  3. It helps in rechecking error and modifying the system as required. 
  4. It helps in the demarcation of activities. 
  5. It provides an integrated and analytical projection of future course of action.  

Systems analysis is both an approach to problems and a body of techniques to aid their solution. As an approach, it follows scientific management theory; as a body of techniques, it draws on mathematics, operations research and the 'use of computer:' 

Systems analysis may be applied to any operation, provided that there are some specified directions for performing the task and that it is one that is performed repetitively. The first step in systems analysis is the determination of the status quo-what are we doing and how are we doing it. The design of improved systems cannot begin until existing systems are completely understood.
