Enterprise-Level Business System Assessment Several key areas should be reviewed when assessing an enterprise-level business system. It is commonly known that errors made in the early stages of the System Development Life Cycle (SDLC) can be quite costly. Therefore‚ careful planning‚ during the early stages of system development‚ is crucial. The use of information-gathering tools‚ during the analysis stage‚ is useful and recommended. Following will be a review of several of the information-gathering

System development life cycle models Waterfall Model The waterfall model is the simplest and most popular system development life cycle model for software engineering. In this model‚ each phase is organized in linear and sequential order. Once a phase is completed‚ one can then proceed to the development of the next phase. It must be noted however‚ that once a stage is completed‚ there is no turning back. The stages in the waterfall life cycle modal are as follows: • Requirements Analysis •

In other to acquire an IT application to perform a required function‚ a company will have to justify the IT investment. It is possible to acquire an IT Application by buying off-the-shell‚ leasing an application‚ using an Open-Source Software

Systems Development Life Cycle Model The Systems Development Life Cycle model was developed as a structured approach to information system development that guides all the processes involved from an initial feasibility study through to maintenance of the finished application. SDLC models take a variety of approaches to development. Some of these life cycle models include: The Waterfall Model: A classic SDLC model‚ with a linear and sequential method that has goals for each development phase. The

Expenditure of Non-staff is divided into direct and indirect expenses. Direct expenses are linked with the patients‚ such as medical and surgical supplies and drugs. Whereas‚ indirect expenses are expenses for items such as utilities‚ comprising of gas‚ electricity‚ maintenance and support functions. As a ward manager‚ it is very important to be knowledgeable about cost effectiveness. It’s a strategy that helps to maintain the equilibrium between cost and quality.

The Traditional Life Cycle Whatever methodology you selected‚ you would likely find four common threads - analysis‚ design‚ "programming"‚ and implementation. Programming here may be loosely interpreted to include packaged software and even outsourcing‚ which will be addressed shortly. It seems somewhat obvious that before you can create‚ improve‚ or replace an information system‚ you should stop to study the current system‚ whatever it might be‚ to see how it operates. This is typically an

of all intellectual functions‚ problem solving has been defined as higher-order cognitive process that requires the modulation and control of more routine or fundamental skills. Problem solving occurs when an organism or an artificial intelligence system needs to move from a given state to a desired goal state. There are many approaches to problem solving‚ depending on the nature of the problem and the people involved in the problem. The more traditional‚ rational approach is typically used and involves
