Software Development Life Cycle - SLDC

 Do you know what software development life cycle phases is? Don’t know? Don’t worry! Here is the detailed information about it. Let’s have a look at it. Here we will be learning all aspects of the Software Development Life Cycle. There are six stages of SLDC model.

Software Development Life Cycle - SLDC

What is the software development life cycle? It is a process used by the software industry to develop, design, and test high-quality software. It aims to produce high-quality software which fulfils customer expectations and completes within given time and cost approximations.

There is a software development life cycle phases, and it contains six stages. Here are those six stages:

1. Planning and Requirement Analysis: In SDLC, requirement analysis is a vital and fundamental stage. Moreover, it is performed by the senior members of the team. Furthermore, this information is used to plan the project approach. The top team plans a meeting with end-user(who will be finally using the software) to gather requirement, neogothic on the condition and Performs analysis. At this stage, the BRD(Business Requirement Document) or FSD(Functional Specification Document)is prepared.

2. Defining Requirements: After the analysis of requirement is done, the next step is to identify and document the product requirements and gets them accepted by customer or market analysts. Moreover, it is done with the help of software requirement specification (SRS). Check if the given requirement is technically feasible.

3. Designing the Product Architecture: A design approach defines all the architectural modules of the product with all its communication and data flow representation along with the external and third-party modules.

4. Developing the Product: At this stage of the software development life cycle, the actual development begins. The programming code is created according to the Design Document Specification (DDS). If the design is completed in a detailed and planned manner, the code generation can be done without any issue.

5. Testing the Product: This is a stage where the testing of software is done. In this stage during software testing, defects are tracked, reported, fixed, and retested until the product reaches quality standards.

6. Deployment in the Market and Maintenance: Once the product testing is completed, then it is ready to be launched in the market.

Five different “Software development life cycle models” models that are widely used are given below:

1. Waterfall Model

2. Iterative Model

3. Spiral Model

4. V-Model

5. Big Bang Model

 Now, you have detailed information about all stages of the software development life cycle and different models of it. It’s very easy to understand! What do you say, friends? If you have any doubts about this topic, then please leave a comment below.
