What Is SDLC? Understand the Software Development Life Cycle
Conducting a feasibility study and performing a SWOT (strengths, weaknesses, opportunities, and threats) analysis are important tools to be used in this stage. These are the approaches that can help you to deliver a specific software model with unique characteristics and features. Similarly, automated and cloud-based platforms, which simulate testing environments, take a significant amount of manual time out of this stage of the system development life cycle. Selenium, a browser testing tool, is one popular example of such a platform. There are various approaches to testing, and you will likely adopt a mix of methods during this phase.
All parties agree on the goal upfront and see a clear plan for arriving at that goal. Application performance monitoring (APM) tools can be used in a development, QA, and production environment. This keeps everyone using the same toolset across the entire development lifecycle. Becoming a software developer requires learning the key skills, programming languages, and concepts needed to build software products.
Life cycle
Business analyst and Project organizer set up a meeting with the client to gather all the data like what the customer wants to build, who will be the end user, what is the objective of the product. Before creating a product, a core understanding or knowledge of the product is very necessary. The Information System Architect is responsible for selecting the high-level tech stack and component structure of the future solution.
Again, agile’s goal is to reduce cost, increase collaboration and customer satisfaction. This stage includes the development of detailed designs that brings initial design work into a completed form of specifications. This work includes the specification of interfaces between the system and its intended environment, and a comprehensive evaluation of the systems logistical, maintenance and support requirements.

Software development life cycle (SDLC) is the term used in the software industry to describe the process for creating a new software product. Software developers use this as a guide to ensure software is produced with the lowest cost and highest possible quality in the shortest amount https://www.globalcloudteam.com/ of time. Software testing and debugging are phases that are included in the systems development life cycle. As a leading provider of application security testing solutions, Veracode makes it easy for developers and security teams to integrate security throughout the SDLC.
- The system specification represents the technical requirements that will provide overall guidance for system design.
- Each phase includes a set of major activities; exit criteria are used to determine whether the team can move on to the next phase.
- Once you’ve completed all testing phases, it’s time to deploy your new application for customers to use.
- Work that is being shaped in the current cycle may be given to designers and engineers to build in a future cycle.
- The training process should simulate actual use, and the team should not assume that users can learn on their own without assistance.

- “Full conformance to outcomes” can be claimed if all required outcomes of the declared processes are met.
An agile approach consists of early and frequent software delivery, frequent communication, continuous change, and simplicity. Agile does not necessarily mean faster, but it does mean that the customer and work teams see results quicker. The most common framework is scrum, and you will also encounter Kanban, XP (Extreme Programming), Crystal, and Lean Development.
Steps in SDLC
This is accomplished through “SRS”- Software Requirement Specification document which contains all the product requirements to be constructed and developed during the project life cycle. The development team must determine a suitable life cycle model for a particular plan and then observe to it. DevOps professionals also work side-by-side with developers and testers to help monitor the end product across its cloud infrastructure, scalability, and load. This unique role frequently moves several times throughout SDLC phases, formulating requirements for the system along the way for the next development cycle, and upholding SDLC standards.
Typically, each stage must be completed before the next one can begin, and extensive documentation is required to ensure that all tasks are completed before moving on to the next stage. This is to ensure effective communication between teams working apart at different stages. This approach implies a linear type of project phase completion, where each stage has its separate project plan and is strictly related to the previous and next steps of system development.
Advantages and disadvantages of SDLC
The Iterative model is often favored because it is adaptable, and changes are comparatively easier to accommodate. This is particularly important for large systems, which usually are more difficult to test in the debugging stage. Lack of design since changes are being put in the system might unknowingly affect other parts of the system. Some members do not like to spend time writing, leading to the additional time needed to complete a project. Too much time spent attending meetings, seeking approval, etc. which lead to additional cost and time to the schedule.
Each loop within the spiral is called a phase and they can be defined based on the needs of the project managers in terms of risks. Another interesting aspect of the spiral model is its radius which represents the costs of the project while the angular dimension sheds light on the progress being made on the project in each current phase. By having the product emulate expected behavior on a small scale and in a controlled environment, it’s easier for developers to visualize components to ensure the software solves the needs it was designed for.

Learning about major methodologies of SDLC, along with their benefits and drawbacks, enables you to set up effective system development processes that deliver the best possible outcomes. The Iterative model incorporates a series of smaller “waterfalls,” where manageable portions of code are carefully analyzed, tested, and delivered through repeating development cycles.
Waterfall Model
It is similar to the Waterfall model with the addition of comprehensive parallel testing during the early stages of the SDLC process. This phase of the system development life cycle is often split into different sub-stages, especially if a microservice or miniservice architecture, in which development is broken into separate modules, is chosen. DevOps engineers are essential for allocating self-service resources systems development life cycle process to developers to streamline the process of testing and rollout, for which CI/CD is typically employed. It’s also important to know that there is a strong focus on the testing phase. As the SDLC is a repetitive methodology, you have to ensure code quality at every cycle. Many organizations tend to spend few efforts on testing while a stronger focus on testing can save them a lot of rework, time, and money.
The term was coined in the year 2001 when the Agile Manifesto was formulated. The project manager is the overall control agent for a strong SDLC process. DevSecOps, an extension of DevOps, is a methodology that emphasizes the integration of security assessments throughout the entire SDLC. It ensures that the software is secure from initial design to final delivery and can withstand any potential threat. During DevSecOps, the team undergoes security assurance activities such as code review, architecture analysis, penetration testing, and automated detection, which are integrated into IDEs, code repositories, and build servers.
The System Development Life Cycle (SDLC)
Other steps which may appear include project initiation, functional specifications, detailed specifications, evaluation, end-of-life and other steps that can be created by splitting previous steps apart further. Fundamentally, SDLC trades flexibility for control by imposing structure. Once a system has been stabilized through testing, SDLC ensures that proper training is prepared and performed before transitioning the system to support staff and end users.
