Software Development Life Cycle (SDLC)

Introduction

The SDLC, or Software Development Life Cycle, is a systematic process follow developers and organizations to design, develop, test and deploy the software, such that high-quality software Development Life Cycle, is deliver to customers in minimum possible cost and time and the development is efficient and meet user requirements. It outlines the path taken to get software from plan to completion.

Planning Phase in Software Development Life Cycle (SDLC)

The first phase of the SDLC is planning, here the project is decide, and the feasibility of the software look into, developers, managers and stake holders are meeting discussing requirements, costs, risks and deadlines. The stage is crucial as it forms the entire basis of the project, by designing the system well it can help remove bugs and increase efficiency in later stages.

Requirement Analysis in Software Development Life Cycle (SDLC)

The phase next to planning phase is requirement analysis phase. At the requirement analysis phase, all information about what a software requires from a user collect. The requirements collect from the stakeholders and documented functionally and non-functionally by an analyst. Functional requirements describe the behavior and functions of the system. Non-functional requirements are about system’s performance, such as security and usability. Accurate requirement analysis could avoid the communication gap among users while developing.

System Design in Software Development Life Cycle (SDLC)

This is where the structure or architecture of the system create in the SDLC. This involves designing the database, the user interface and the architecture of the system itself. It is very important to create design documents in the design stage to ensure the architecture of the system is successful, flexible, easy to scale up, efficient and has the features users require. It helps reduce the risk in the development stage and increase system efficiency.

Implementation Phase in Software Development Life Cycle (SDLC)

During this stage actual coding and programming work starts. Developers are responsible for coding all the required modules according to the design documents and specified programming language. Each module is design as a standalone system and then merged to form a complete system.

Testing Phase in Software Development Life Cycle (SDLC)

After its development, the software is now subject to testing. Software engineers from quality assurance department test the system to ensure that it has no errors or bugs and it functions perfectly and does not hang the system. Several tests are conduct on the software and there unit testing, integration testing and system testing.

Deployment Phase in Software Development Life Cycle (SDLC)

Once the software has passed the test stages it will be deployed to the production environment. Users will now be able to use and run the software in actual conditions. Depending on the necessity of the project, it is deployed all at once or in bits, efficient deployment will make life easier.

Maintenance Phase in Software Development Life Cycle (SDLC)

The last stage in SDLC is Maintenance stage. Once the system is implement it is kept under observation and bugs find user or developer is remove. Updates release to remove bugs. It also involves to enhancing performance or adding of features that is request by user.

Conclusion

The SDLC is very important to develop and build the effective and reliable software systems. Organizations can improve software quality, decrease risks, and make software to meet the user requirements when following some standard steps: planning, design, develop, test, deployment and maintenance.
