What is software development life cycle?

Software development lifecycle (SDLC) is a methodology utilized to design and develop all sorts of high-quality software.  

In this blog, you will get to know all about SDLC, its stages, and its uses. 

What is Software Development Life Cycle? 

Software Development Life Cycle is an approach to transform a newly generated project into an operational projectIt provides a framework for all sorts of activities to create a system that can meet the standards of the organization. 

SDLC consists of 7 steps that give a comprehensive overview of how the software can be designed, developed, and displayed.  

The seven phases provide a clear idea of where the system needs changes. It also allows you to repeat steps or rewrite a previous step. 

Phases of Software Development Cycle 

They include: 

  1. Planning 
  1. Systems analysis and requirements 
  1. System design 
  1. Development 
  1. Integration and testing 
  1. Implementation 
  1. Operations and maintenance 

Let’s discover each step in greater detail: 

Planning 

It includes the pre-work that goes on before you start. The rationale of the first step is to outline the difficulty of the problem and identify possible solutions. Time, capital, finances, benefits, and many other relevant factors are considered.  

Systems analysis and requirements 

Here, the teams consider the functional elements of the project. Critical analysis of whether the new system can meet specific requirements is done.  

The system analysis helps to map out all the requirements, the individuals responsible, and the time frame to follow for completion. 

System design 

Specifications like Hardware or software, networking features, functionalities, processing, and processes are considered at this level for the device to achieve its required objectives. 

Development 

This is where the actual work starts. The developers use their expertise and this step marks the start of the development process. 

Integration and testing 

This is the assessment of whether the developed project meets the objectives. The testing team tests the functionality, which leads to instant identification of problems and bugs. Wherever glitches are detected, they are promptly rectified. Testing is done till a high-quality system is developed. 

Implementation 

This step involves the actual implementation of the developed system. Developers code according to the requirements and the design discussed in previous stages to produce the required deliverables. 

Operations and maintenance 

After the system is deployed, the purpose of this step is to make amendments to meet the criteria of the end-users. It includes making changes to improve a system’s performance, rectify errors, or increase security. 

Wrapping Up 

The above-mentioned seven stages of the Software Development Life Cycle ensure consistency of the system produced. They provide the much-needed structure for all the operations.
