What is SDLC and what it has to do with software development?

SDLC is an abbreviation of Software Development Life Cycle. It is a framework designed to define & organize the whole process of software development. This is the process followed by the software development team of any software company to develop a software, this helps in performing tasks in a proven process for developing software. It contains a detailed plan describing how to develop and maintain software.   

  1. Its a well-defined set of principles and combined methodologies for delivering software projects
  2.  It contains every single step that is involved in the life cycle of software.
  3. Provides a common framework.

1. Planning & Analysis

Planning and analysis for software development is done on the basis of market research, customer feedback and future scope of that software solution. In this step, we identify whether there is a need for a new system or not. The company might be trying to meet expectations for it’s customers. Resources, costs, time, benefits and other items should be consider at this stage.

2. Defining & Documenting Requirements

Once the planning and analysis phase is completed we clearly define the requirements and the functions that this software is going to perform. Now we prepare a proper document where we provide functionalities and actionable of software in well-written format.

3. System Design

In this step of SDLC(Software Development Life Cycle) the architecture or the flow of operations is drafted as a design of the software. Here we use the information collected from the above steps to design the software.  This is the step for end users to discuss and determine their specific business needs for the proposed system. A design approach clearly defines all the architectural modules of the product along with its communication and data flow representation.   

4. System Development

In the development phase, the software comes in it’s actual shape. Here the code is generated according to the design and functionality of the software. 

The developers use compilers, interpreters & different programming languages such as C++, C#, Java, Bb.net etc to perform the coding of the software. According to the functionality, operation and devices on which the software will run, we choose the programming language.    

5. Testing & Approval

The testing phase is a phase of the SDLC process, where we perform the testing of the software on different factors. In this step the software testing experts  find the bugs in the software. These bugs can be design mistakes or functionality mistakes. In the testing phase the software is also tested on is this software is fulfilling the business needs or not. 

After all these testing phases the bugs are founded and fixed then only the software gets approval.

6. Maintenance

Maintenance is the last step involved in the SDLC process. After the software is delivered in the market the company provides the maintenance for that software. The updates are also provided on regular basis.
