Software Development Life Cycle Models and Methodologies

Mohamed Sami

Introduction

The software industry includes many different processes, for example, analysis, development, maintenance and publication of software. This industry also includes software services, such as training, documentation, and consulting.

Our focus here about software development life cycle (SDLC). So, due to that different types of projects have different requirements. Therefore, it may be required to choose the SDLC phases according to the specific needs of the project. These different requirements and needs give us various software development approaches to choose from during software implementation.

Types of Software developing life cycles (SDLC)

· Waterfall Model

· V-Shaped Model

· Evolutionary Prototyping Model

· Spiral Method (SDM)

· Iterative and Incremental Method

· Extreme programming (Agile development)

Waterfall Model

Description

The waterfall Model is a linear sequential flow. In which progress is seen as flowing steadily downwards (like a waterfall) through the phases of software implementation…
