What is SDLC? Software Development Life Cycle Definition & Guide

These phases aid in identifying and correcting flaws early in the development process, which can assist to enhance software quality. The Software Development Life Cycle (SDLC) is a process that defines the tasks that software developers perform to plan, design, develop, test, and deploy software. It is a systematic approach to software development that aids in the creation of software to ensure that it is developed in a consistent and efficient manner. Each SDLC model offers a unique process for your team’s various project challenges.

You can specialize in cloud computing or mobile app development or become a generalist who is an expert at applying the SDLC across many types of software. SRS is a reference for software designers to come up with the best architecture for the software. Hence, with the requirements defined in SRS, multiple designs for the product architecture are present in the Design Document Specification (DDS). DevOps is a set of practices and philosophies that combines software development and IT operations. This practice takes SDLC concepts to the next level by introducing high levels of automation and focusing on smaller software releases.

Reduced costs

But by going through these steps you can reduce your time to market, ensure a better product output, save money, and increase the likelihood of product market fit. The system is developed along with quality assurance checks and testing processes at this stage. Requirements are collected and the overall objective is identified during this phase.

During the analysis phase, a programmer develops written requirements and a formal vision document via interviews with stakeholders. In this phase, developers start build the entire system by writing code using the chosen programming language. In the coding phase, tasks are divided into units or modules and assigned to the various developers. It is the longest phase of the Software Development Life Cycle process.

SDLC Best Practices

Sequential or big-design-up-front (BDUF) models, such as waterfall, focus on complete and correct planning to guide larger projects and limit risks to successful and predictable results. [6] Anamorphic development is guided by project scope and adaptive iterations. The waterfall model provides discipline to project management and gives a tangible output at the end of each phase. However, there is little room for change once a phase is considered complete, as changes can affect the software’s delivery time, cost, and quality. Therefore, the model is most suitable for small software development projects, where tasks are easy to arrange and manage and requirements can be pre-defined accurately.

  • The exact number and nature of steps depend on the business and its product goals.
  • Conceptually, the design flows from one phase down to the next, like that of a waterfall.
  • SDLC stands for Software Development Life Cycle and is also referred to as the Application Development life-cycle.
  • SDLC and SAD are cornerstones of full life cycle product and system planning.

Start building your development around a strict Software Development Life Cycle and stay a step ahead of competitors still relying on an old-school approach to product design. The agile model requires the team to work in sprints that last for 2 to 4 weeks, each with unique requirements and goals. At the end of a sprint, the product owner verifies the code and greenlights its deployment to users. The team then gathers feedback and starts preparing for the next sprint.

V-Shaped Model

Team members participate in a daily scrum (or daily standup) meeting where each person reports on their individual progress. At the end of the sprint, the team demonstrates their potentially shippable increment to stakeholders, conducts a retrospective, and determines actions for the next sprint. Learners are advised to conduct additional research to ensure that courses and other credentials pursued meet their personal, professional, and financial goals.

The project’s specifications and intended results significantly influence which model to use. For example, the waterfall model works best for projects where your team has no or limited access to customers to provide constant feedback. However, the Agile model’s flexibility is preferred for complex projects with constantly changing requirements.

Stage-6: Deployment and Maintenance of Products

Adopting an SDLC strategy also lowers your team’s technical debt since developers take little to no shortcuts during software creation. Different SDLC methodologies (or models) prioritize different aspects of product creation software development life cycle definition and measure success in unique ways. Let’s look at the most popular SDLC methodologies you can adopt at your company. He was able to allocate resources to the planning phase before he started to do anything else.

SDLC comprises a detailed description or step-by-step plan for designing, developing, testing, and maintaining the software. This stage includes the development of detailed designs that brings initial design work into a completed form of specifications. The detail design and development is responsible for producing the product, process and material specifications and may result in substantial changes to the development specification. The term “agile” describes an approach to software development that emphasizes incremental delivery, team collaboration, and continual planning and learning.

Software Deployment

SDLC strategies have been around since the 1960s, and most of its core concepts have evolved over time. The spiral model is an iterative software development approach that involves risk assessment. The spiral model’s phases are repeated several times, with each iteration enhancing the program and lowering the likelihood of faults.

Because many teams immediately test the code they write, the testing phase often runs parallel to the development phase. Once you’ve come up with some ideas, it’s time to organize them into a cohesive plan and design. This requires a lot of research and planning to ensure that your final product meets your expectations (and those of your customers). The big step is creating a detailed project plan document and work breakdown structure that outlines the requirements.

Bringing It All Together: The SDLC Approach

In this phase, Developer needs to follow certain predefined coding guidelines. They also need to use programming tools like compiler, interpreters, debugger to generate and implement the code. Stackify’s APM tools are used by thousands of .NET, Java, PHP, Node.js, Python, & Ruby developers all over the world.
