¶ … Systems Development Life-Cycle is a framework for an evolution from abstract ideas to a concrete reality
Systems development life-cycle (SDLC) is a structured process of systems development is an evolutionary process that proceeds from a broad concept of information requirements and finally ends into the manufacturing of a product -- development of a new system. From this conception it can be seen that the ideas of SDLC begin to narrow down from an abstract concept to the concrete reality.
In a broad sense, SDLC starts with the following five steps-- investigation, analysis, design, implementation, and maintenance. While all of the activities in different steps are interrelated and interdependent, therefore in reality many of these steps run concurrently. However, the critical point cannot be denied that SDLC is an evolution from abstract ideas to the reality.
The first two steps -- systems investigation and systems analysis -- are abstract concepts that deal with finding business problems and opportunities, conducting...
All of the above concepts at best can be construed as abstract. However, the systems developers have agreed on the big picture, it is often easier to come to the concrete reality of coming to the development of specifications for hardware, software, network, and data resources, and the information systems of the proposed systems.
For example, in the design process we begin with the prototypes of new applications, that is an iterative process of application development. Development of a prototype is a concrete reality that moves beyond the process of the abstract conception of the SDLC.
As we begin to move even further, the systems development steps begin to be more concrete. For example, in the systems development implementation process, the main tasks become to acquire or develop hardware and software, test the system and train the people so that they can use…
