WATH IS A SDLC?

SYSTEMS DEVELOPMENT LIFE CYCLE

IS A PROCESS FOR PLANNING,

CREATING, TESTING, AND DEPLOYING

AN INFORMATION SYSTEM.

WATH IS A SDLC?

• Software Development Life

Cycle. consists of a complete plan

explaining the way to develop,

maintain and replace specific software

system

DISADVANTAGE OF SDLC

• The concept of an SDLC (System Development Life Cycle) is meant to be an advantage. It’s a common framework that makes maintenance easier and we are often blinded to the importance of maintenance. The disadvantage is that people and projects need flexibility.

SOFTWARE DEVELOPMENT LIFE

CYCLE PROCESS

• SDLC is a process which defines the various stages involved in the development of software for delivering a high-quality product.

CONTI…

• Adhering to the SDLC process leads to the development of the software in a systematic and disciplined manner.

PURPOSE:

• Purpose of SDLC is to deliver a high- quality product which is as per the customer’s requirement.

SDLC PHASES

• System Development Life Cycle Phases:
• Given below are the various phases:
• Requirement gathering and analysis
• Design
• Implementation or coding
• Testing
• Deployment
• Maintenance

1) REQUIREMENT GATHERING AND

ANALYSIS

• During this phase, all the relevant information is collected from the customer to develop a product as per their expectation.
• Any ambiguities must be resolved in this phase only.

2) DESIGN

• In this phase, the requirement gathered in the SRS document is used as an input and software architecture that is used for implementing system development is derived.

3) IMPLEMENTATION OR CODING

• Implementation/Coding starts once the developer gets the Design document. The Software design is translated into source code.
• All the components of the software are implemented in this phase.

CONTI….

• Retesting, regression testing is done until the point at which the software is as per the customer’s expectation.
• Testers refer SRS document to make sure that the software is as per the customer’s standard.

5) DEPLOYMENT

• Once the product is tested, it is deployed in the production environment or first UAT (User Acceptance testing) is done depending on the customer expectation.
