7 Stages of System Development Life Cycle:- Every computer-based system has a life cycle. Just as all living beings follow a life cycle. System Development Life Cycle (SDLC) is a well-defined process by which a system is conceived, developed and implemented. The system development life cycle consists of the following phases. Preliminary survey or Investigation. […]
CASE Tools Stand for Computer Aided Software Engineering tools. CASE Tools for System Analyst: As the name implies they are computer-based programs to increase the productivity of analyst. System analysis is used in every field where something is developed. Analysis can also be a series of components that perform organic functions together, such as system […]
Cost-Benefit Evaluation:-The primary objective of cost-benefit analysis is to find out whether it is economically worthwhile to invest in the proposed project. The common methods for Cost-Benefit Evaluation are:- Payback Method Present Value Method Net Present Method Net Benefit Method Break-Even Method Cash Flow Analysis Payback Method Payback analysis defines the time required to […]
Cost-Benefit Analysis:- The primary objective of cost-benefit analysis is to find out whether it is economically worthwhile to invest in the proposed project. Generally, a project has a high return on investment if it has a high return on investment. Cost-Benefit Analysis Steps- Identification of costs & benefits. Classification of costs & benefits. Selection of […]
Roles of System Analyst:- A systems analyst is a person who uses analysis and design techniques to solve business problems using information technology. Systems analysts may serve as change agents who identify the organizational improvements needed, design systems to implement those changes, and train and motivate others to use the systems.

What is prototyping:- Prototyping is a working model which is based on the interaction between analysts & users, built as a preliminary solution to a problem. A prototype is built, tested & then reworked as necessary until an acceptable prototype is finally achieved from which the complete system can be developed. Types of Prototypes […]
