Manual Testing training
  • The term ‘Software Development Life Cycle(SDLC)’ refers to the process of developing software. The software industry uses it to design, develop and test high-quality products. The goal of the SDLC is to make software that meets client expectations, is finished on time, and is affordable.
  • The Software development life cycle (SDLC) is a set of activities and deliverables that are used to build software. It is a way to keep track of and control projects.
  • SDLC is an organized process for building software that ensures the quality and correctness of the built software.
  • It’s a plan that explains how to make, keep, replace, change, or improve specific software.

SDLC consists of several phases. Let’s discuss in detail:

SDLC Phases

Stage 1: Planning And Requirement Analysis

  • Requirement analysis is the most important part of the SDLC.
  • The process is performed by the senior team members with input from the clients and domain experts in the industry.
  • It is used to plan the project’s approach and to do product feasibility studies in the economic, operational, and technical areas.
  • At this stage, it is also important to plan for the quality assurance requirements and identify the risks associated with the project.

Stage 2: Defining Requirements

  • The next step after the requirement analysis is to define and document the product requirements and get them approved by the client or market analysts.
  • In this phase, we need to create an SRS (Software Requirement Specification) document in order to define and document requirements.
  • The SRS is the product requirements that need to be designed and developed during the projects’ life cycle.

Stage 3: Designing The Product Architecture

  • In this phase, SRS is used to make the system and software design documents. This helps to define the whole systems’ architecture.
  • Based on the requirements in SRS, more than one design approach is usually suggested and written down in a DDS — Design Document Specification for the product architecture.
  • This DDS is looked at by all the important people like stakeholders and based on things like risk assessment, product strength, design modularity, budget, and time. This process assists in determining the most effective design approach for the product.

Stage 4: Building Or Developing The Product

  • The development phase of the software development lifecycle typically begins with the initiation of code.
  • When design is achieved in a detailed and organized manner, code generation can be achieved without much trouble.
  • Developers have to follow the coding standard set by their organization and the programming languages and tools they use.
  • In the coding phase, tasks are divided up into units or modules and given to the different developers.

Stage 5: Testing The Product

  • Once the development phase is finished. The product is deployed into a testing environment.
  • The testing team begins testing the entire pieces of software functionality. This is done to make sure the whole application works according to the client’s requirements.
  • During this phase, the quality assurance and testing team may encounter errors or defects that they communicate to the development team. The development team resolves the issue and requests a re-test from the testing team.

Stage 6: Deployment And Maintenance

  • Once the testing phase is over and the system/software doesn’t have any bugs or errors, the deployment process will start.
  • After the product’s are released and clients start using it, maintenance is needed for the existing customer base. This includes bug fixing, upgrading, and adding new features.
  • Maintenances main job is to make sure that requirements are met and that the system is working as it is supposed to.
