That’s basically what any project management methodology is all about. The whole project, from start to finish, is evenly divided into phases. The software development life cycle (SDLC) is how it’s done in software development. Let’s define it, look at different models and the best way to manage SDLC. In those days, teams were small, centralized, and users were ‘less’ demanding. This type of scenario meant that there was not a true need for refined methodologies to drive the life cycle of system development.
This step builds upon the planning stage, building out the tasks you need to do in the work breakdown schedule. There are plenty of tools available, such as Adobe XD or InVision, that make this process much easier than ever before. During the Analysis stage, the focus is on gathering and understanding the requirements of the system. This includes conducting interviews, studying existing processes, and identifying stakeholders’ needs. The gathered information serves as a basis for designing a system that meets users’ expectations and addresses organizational challenges. The agile model was mainly designed to adapt to changing requests quickly.
Stage-3: Designing Architecture
The term software development lifecycle (SDLC) is frequently used in technology to refer to the entire process of technology innovation and support. Rapid development cycles help teams identify and address issues in complex projects early on and before they become significant problems. They can also engage customers and stakeholders to obtain feedback throughout the project lifecycle.
It ensures that the software is secure from initial design to final delivery and can withstand any potential threat. Developers are now responsible for more and more steps of the entire development process. It then creates the software through the stages of analysis, planning, design, development, testing, and deployment. By anticipating costly mistakes like failing to ask the end-user or client for feedback, SLDC can eliminate redundant rework and after-the-fact fixes. Today, most teams recognize that security is an integral part of the software development lifecycle.

So rather than creating a timeline for the project, agile breaks the project into individual deliverable ‘time-boxed’ pieces called sprints. This model prioritizes flexibility, adaptability, collaboration, communication, and quality while promoting early and continuous delivery. Ultimately, all this ensures that the final product meets customer needs and can quickly respond to market demands. DevSecOps, an extension of DevOps, is a methodology that emphasizes the integration of security assessments throughout the entire SDLC.
In fact, many project managers use SDLC as a guide for managing their projects. Many of these models are shared with the development of software, such as waterfall or agile. Numerous model frameworks can be adapted to fit into the development of software. Each company will have their own defined best practices for the various stages of development. For example, testing may involve a defined number of end users and use case scenarios in order to be deemed successful, and maintenance may include quarterly, mandatory system upgrades. The most flexible of the SDLC models, the spiral model is similar to the iterative model in its emphasis on repetition.
Software Testing
The System Development Life Cycle (SDLC) provides a well-structured framework that gives an idea, of how to build a system. It consists of steps as follows- Plan, Analyze, Design, Develop, Implement and Maintain. We will delve into the significance of each sdlc system development life cycle stage, emphasizing the critical role played by System Design in the overall process. The information from this analysis forms the building blocks of a basic project. Thus, in this stage, the basic project is designed with all the available information.
- Hence, the Agile SDLC model has recently become increasingly popular and in demand.
- A fully integrated end-to-end value stream management platform, and cloud-based software development platform to visualize and manage the flow of value.
- This stage involves deploying the developed system into the production environment.
- A tremendous amount of time was spent on the planning phase of the app’s development.
- SDLC consists of six steps which I have diagrammed here for your reference.
- During this phase, you need to analyze the problem in the context of the organization’s policies and objectives.
During this step, current priorities that would be affected and how they should be handled are considered. A feasibility study determines whether creating a new or improved system is appropriate. This helps to estimate costs, benefits, resource requirements, and specific user needs. 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 name of the phases might vary, but the following list summarizes the core functions of typical SDLC phases. This methodology is referred to as a waterfall because the output from one stage is the input for the next stage. The adoption of his technology is proof that SDLC, when applied and executed correctly, can lead to profound technological and business outcomes.
Process checks include review of timelines and expenses, as well as user acceptance. Once the requirement analysis is done, the next stage is to certainly represent and document the software requirements and get them accepted from the project stakeholders. The development team must determine a suitable life cycle model for a particular plan and then observe to it. SRS is a reference for software designers to come up with the best architecture for the software.
Stages of the Software Development Life Cycle Model
For example, if you strive to build software designed for hourly employees, as Zoomshift has done, or time tracking software, you would start at the “requirement analysis” stage. As technology advances, new tools like generative AI are shaking up the SDLC process, making development even faster and more exciting. So, whether you’re coding or designing, SDLC is your key to crafting software that stands out in the digital world. AI-powered language models enhance communication between stakeholders and developers by understanding and processing user queries accurately. The Spiral model combines iterative development with risk assessment, involving repeated cycles of planning, risk analysis, engineering, and evaluation.
The document sets expectations and defines common goals that aid in project planning. The team estimates costs, creates a schedule, and has a detailed plan to achieve their goals. Once you’ve got your design plans in front of you, it’s time for wireframing and mockups.
Test case development
The v-shaped model is very similar to the waterfall model, in that it also features a rigid, well-thought-out plan (this time in a v shape). However, the biggest difference between v-shaped and waterfall is that the v-shaped model has a big emphasis on testing. Testing should be completed after each phase in order to reduce errors as the team progresses through the plan. This can be done by a single developer, a larger team or even several teams depending on the scope of the work.
