Extract of sample "System Development Life Cycle"

Download file to see previous pages As the prototype or demo system is further defined, feedback is elicited from users (Harbison, 1997) Thus, the domain models, reference requirements, and reference architecture are continually validated. The prototype or demonstration system development process provides further validation of these requirements and models and identifies needed refinements.
It can be problematic in the situation where the customer after viewing the prototype considers it to be the final version, satisfies and demands a few more changes without analyzing the back end development complications.
The iterative model is the actual implementation of the Waterfall model, due to which it is termed as a “mini-waterfall model”. The reason behind is simple as it implements a waterfall process in various phases or chunks.
While comparing different SDLC models with the traditional model, one can easily judge the variations followed by enhancements from time to time. The waterfall model is the oldest one, similarly, the prototype and RAD models are the extensions of the waterfall model, and finally, the user-end model, which is the latest, and is an augmentation of the RAD and prototype model.
Many factors contribute to the problems of delivering computer-based systems. The Standish Group (Johnson, 1995) reports reasons for project failure that include lack of user involvement, lack of executive management support, poorly stated or incomplete requirements, and politics. Individual developers report problems ranging from insufficient memory to cultural shock.
The primary outcome of systems investigation is a systems investigation report, which summarizes the results of a systems investigation and the process of feasibility analysis. ...Download file to see next pagesRead More

Problem Solution Development Life Cycle

... s PSDLC Applying the Six Steps of 'Problem Solution Development Life Cycle' (PSDLC) 10/9/2009 Introduction PSDLC: PSDLC is the standard technique used mostly by software engineers to create the basis outline and the blueprint of the concluding software. The process to do so is made simple through the notion of PSDLC, wherein the software engineer or the consultant shall thoroughly analyze the problem and then as a general rule of thumb, must come up with one or more solutions to the problem, after which the engineer shall create the blueprint of the software and realistically test it to check if the problem has been entirely resolved. The philosophy of PSDLC lies in the six orchestrated steps (DeGrace & Stahl, 1990, pp. 116-142): 1...
