System Planning and Design Name: Institution Date: Abstract Information technology is a fast changing world of computing. With changes in base systems, hardware and applications, information system building has become to be critical and thus requiring extra keen while undertaking the decision making stage followed by design stage, implementation stage, testing stage integration and evolution stages…
Extract of sample
In addition it is also imperative to understand hardware platforms for deployment of developed systems such that failure of operation is avoided (Smith, 2012). In this regard requirement analysis becomes essential. Secondly, since the onset of the digital era, there has been overwhelming demand for digitizing existing and forthcoming records and consequently information system building has to solve these problems. Such demand thus calls for specific design that takes into consideration all these requirements hence the need for system specification (Johnson, 2011). When all specific system requirements have been met, it is imperative that design commences. While designing IT experts usually break down system components such that each component is developed independently of the other to avoid numerous system errors. This is also highly encouraged while using implementation of tools that are object oriented. Thus the system is separated into modules, which are independent of each other. Upon clearance of modular development, development stage begins which entails system coding whereby the real transition between human and machine interaction happens (Edwards, 2012). ...
