System Operational Feasibility great deal of time and intellectual resources go into the conceptual design stage of a systems engineering process once a need is clearly defined by the end-user. However, this initial development step is a moot point if the product is not operationally feasible, which means, according to Benjamin Blanchard in his book Systems Engineering and Analysis, "that the system will perform as intended in an effective and efficient manner for as long as necessary."
In order for the systems engineer to determine operational feasibility, it is necessary to properly integrate the design-related specialties such as reliability, maintainability, human factors and supportability.
Reliability is one of the most important design elements, since it confirms or denies the long-term use of the product without major maintenance and repair. Unreliable systems do not meet the original project goals and lead to unnecessary expenditures of valuable resources. Simply stated, "reliability is the probability that a system or product will perform in a satisfactory manner for a given period of time when used under specified operating conditions." The four elements noted -- probability, performance in a satisfactory manner, time and specified operation conditions...
system development life cycle (SDLC) approach to the development of Information Systems and/or software is provided. An explanation of SDLC is offered, with different models applied in implementing SDLC delineated. Advantages and disadvantages associated with each of the models will be identified. System Development Life Cycle According to Walsham (1993), system development life cycle (SDLC) is an approach to developing an information system or software product that is characterized by a

E-Groceries Feasibility Study of E-Groceries Recent technological developments have seen different plans of action being actualized as it relates to e-Groceries retailing. However, challenges have limited the full realization of this aspect with the greatest hindrance has been logistics; more wasteful operation has often prompted resources being utilized on working expenditures. In this case, enhancements geared towards logistical effectiveness are seen as standouts amongst the most essential steps towards the implementation
In fact, an incoherent approach to it can lead to negative effects such as escalation of costs and lowering of efficiencies. It portfolio management addresses this key issue right from the conceptual stage of projects. The portfolio approach ensures that it projects are implemented with shared commitment, within the statutory framework. Some of the important measures implemented are: Collaborative decision making for key and large scale projects Stakeholder commitment and support
