Introduction
- SDLC stands for Software Development Life Cycle.
Definition
- SDLC is a structured process used by software development teams to design, develop, test, deploy, and maintain software products and ensures that the software being developed meets the requirements of the customer.
- SDLC is a framework that provides a systematic approach to software development and ensures that the software being developed meets the requirements of the customer.
Characteristics
- By using the SDLC process, software development teams can reduce the risks of failure, ensure that all requirements are met, and create software that is scalable, maintainable, and easily upgradable.
- The SDLC can vary depending on the organization’s size, the complexity of the project, and the methodology used.
- Some common methodologies used in the SDLC include the Waterfall model, Agile methodology, and DevOps.
Life Cycle/Phases of SDLC
- The SDLC process consists of several phases, including planning, requirements gathering, design, implementation, testing, deployment, and maintenance.
- The phases of SDLC are typically followed in a sequential manner, although some development methodologies may utilize an iterative or agile approach.
- The phases of the SDLC typically include:
-
System Planning:
-
This is the initial phase where the team determines the project’s scope, goals, and requirements.
-
In this phase, we define the scope of the project, identify the goals and objectives, and determine the feasibility of the project are done.
-
-
System Requirements Gathering and System Analysis:
-
In this phase, we collect and analyze user requirements, business rules, and data requirements are done.
- During this phase, the team conducts an in-depth analysis of the project requirements, user needs, and the project’s feasibility.
-
-
System Design:
-
In this phase, we create the architectural design and detailed design of the software based on the requirements.
- In this phase, the team designs the software architecture, database schema, and user interface.
-
-
System Coding/Development/Implementation:
-
In this phase, we build the software using a programming language and development tools.
- This is the actual coding phase where the software development team writes the code for the application.
-
-
System Testing:
-
In this phase, we verify that the software meets the requirements and is free of defects.
- After the code is implemented, the team carries out testing to identify any bugs, defects, or issues that need to be addressed.
-
-
System Deployment:
-
In this phase, we Install the software in the production environment and make it available to end-users.
- Once the testing is completed, the software is deployed and made available to the end-users.
-
-
System Maintenance:
-
In this phase, we update and maintain the software to ensure that it continues to meet the changing needs of the organization and users.
- This is the final phase where the team provides ongoing support and maintenance to ensure that the software runs smoothly and remains up-to-date with the latest technology and user needs.
-
-
Objectives
- The main goal of SDLC is to create high-quality software that meets the needs of the end-users and stakeholders, while also ensuring that it is delivered on time and within budget.
