The Concept of Proto-Typing in the System Development Process
A prototype is basically a scaled down model or working version of product. The prototype is put through various tests, before it is converted into a polished, sleek product. The process of preparing prototype is referred to as “prototyping”. It is consisting of building an experimental system rapidly and inexpensively for the end-user to evaluate. Prototyping is also viewed as “strategy of experimental assurance in development of information system applications to be achieved by an evolutionary design method”. Steps in proto-typing: Step 1: identify the user’s basic requirements At this stage the systems person works with the user to understand user’s basic needs and requirements as regards the output from the systems. The systems person establishes realistic user expectation, estimates the cost of developing the working proto type, defines data elements required and determines data availability. Step2: Develop the initial/Working proto type: The systems person develops the initial working/interactive prototype Continue reading
