SDLC OVERVIEW

What is the system development?

Systems development is the process of defining, designing, testing, and implementing a new software application or program. It could include the internal development of customized systems, the creation of database systems, or the acquisition of third party developed software. Basically there are three system development methods.

System Development Life Cycle-SDLC
Structured system analysis and design method-SSADM
System Prototype Method-SPM

SDLC Overview

SDLC, System Development Life Cycle is a process used by software industry to design, develop and test high quality systems. The SDLC aims to produce a high quality System that meets or exceeds customer expectations, reaches completion within times and cost estimates.

Traditionally, the systems-development life cycle consisted of five stages. That has now increased to seven or eight phases. Increasing the number of steps helped systems analysts to define clearer actions to achieve specific goals.

Preliminary Activity
- Planning the scope
- Appointed team such as basic requirement will be consider
Feasibility Study
- Technical feasibility
- Operational feasibility
- Economic feasibility
System Analysis.
- Identify the problems, barriers, Weaknesses and strong areas in current system.
- After that preparing Requirement Specification.
Detailed design and Programming.
- Planning hardware, Software and live ware, data base and procedure.
System Implementation
- Direct change over.
- Parallel running.
- Pilot operation
Maintenance and review
Project documents
- Feasibility study report
- Requirements specification
- System specification
- Programmed specification
