7 Stages Of System Development Life Cycle Ppt


After the complete architecture and the planned functionality of the solution is built, the testing phase starts. Development team to get a clear understanding of all project goals and collect requirements. In this blog, we have discussed the most popular and widely used SDLC models, as well as different methodologies and processes. Now you know that SDLC processes are unique, and it is impossible to apply the same approach to all products.

This phase sets definite workflows and standards and encompasses a clear overall product design with the database structure. As a result, you’ll get two designs – the logical design and the physical one. Above we have already given you the answer, and now you know that the kanban method stands on the pillars of continuous iteration and testing. Thanks to the kanban project management, it is quite easy to control the workflow, understand how it operates, and give customers the answers they might need. No matter which SDLC model you choose and how perfectly you design your project, without the right software development team, success won’t be possible. It’s like having a room full of Fender guitars and hiring doctors instead of musicians to play (not that doctors can’t play, but you get the point).

Development And Building Phase

However, many software development experts suggest that the requirement collection and analysis stage is the most important aspect of SDLC. This is when the project team begins to understand what the stakeholders expect from the project.

  • The Waterfall methodology is usually broken into seven steps, which require painstaking planning using a Gantt chart.
  • The outputs from the requirements analysis stage will vary depending on the methodology you are using.
  • Then the first step for you is to understand the Software Development Life Cycle .
  • With that being said, let us have a closer look at each of the software development phases.

Hopefully, at the end of the development phase there will be testable and functional software. The SDLC starts with a requirement analysis phase in which the person in charge of the project establishes the software requirements. They analyze the aspects that are necessary to achieve the final goal. Defining and establishing requirements determines what the application will do and the resources needed to build the project.

Feasibility Or Requirements Analysis Stage

With that in mind, we are here with the guide that helps you understand the 7 phases of the System Development Life Cycle in more detail. Compliance and adherence to the SDLC are critical to ensuring the success of any project or software needed to solve a problem or meet a need. The SDLC is a series of 7 stages which define and explain the life-cycle of software development. Customers are involved early on in the process providing feedback and helping to create a software that they will use and meets their needs.

Here end-users have the ability to fine-tune the system to better suit future needs. Using a test script will automatically run a series of predetermined tests to make sure the system is in compliance with the requirements. The tester will test the new system by exploring its uses, features, and capabilities by operating the new system or software. The tester will navigate the system based on experience alone and will evaluate whether it meets requirements or not.


A security testing provider offers tools that enable developers to perform tests on applications and development and production. Veracode delivers the AppSec solutions and services today’s software-driven world requires. Meet the needs of developers, satisfy reporting and assurance requirements for the business, and create secure software. Following the success of Iterative and Incremental software development methods, other software development methods emerged to leverage more project management principles and development practices. It is one of the most popular online project management systems, which is a staple among small companies and startups. It allows teams to efficiently organize their work according to the Japanese kanban board methodology. Trello is the easiest tool to implement into your workflow without long staff adaptation.

If they find any bugs, they relay them to the developers, who then fix the bugs and send back the software for re-testing. In this stage of work, the software is operationalized to ensure there are no issues or incidents related to the deployment. This stage of work can involve reviewing, understanding, and monitoring network settings, infrastructure configurations, and performance of application services in production. This process can involve incident resolution or management in the course of any issues or changes made to impact a customer or user base. As mentioned previously, Software Development Life Cycle is a continuous process from start to finish of a software application. And even though there are specific steps, teams adopt different methodologies that have diverse approaches to build their applications. The most popular SDLC models are Waterfall, V-Shaped, Iterative, Spiral, Big Bang, Prototype, and Agile.

Software Development Life Cycle is a framework defining processes that are aimed to produce software with the lowest cost, highest quality, and in the shortest time. The Manifesto for Agile Software Development was drafted and signed by a group of software developers in 2001. Reading the manifesto, you can see clearly the contrast between Waterfall, then the de-facto standard for development methods, and Agile, the newer method. This makes it possible to quickly and accurately describe all the necessary technical points. And developers are well aware of this approach since they have the necessary knowledge and can quickly and efficiently develop systems according to the developed design.

The software development life cycle focuses exclusively on software components, such as development planning, technical architecture, software quality testing and the actual deployment of the software. Put simply, the system development life cycle is more holistic and comprehensive. With Veracode, developers can find and fix flaws at the most cost-efficient point in the Software Engineering Body of Knowledge development process and produce more secure software with every release. In software engineering, the software development life cycle – mostly known as SDLC – consists of planning, creating, testing, and launching an information system. This process allows tech teams to measure and improve the process’s development as it analyzes each one of these steps in detail.

This step puts the project into production by moving the data and components from the old system and placing them in the new system via a direct cutover. While this can be a risky move, the cutover typically happens during off-peak hours, thus minimizing the risk.

Among all system development life cycle stages, have you ever wondered which is the most important? For Bydrec, every single phase is crucial, so nothing should be left out or rushed.

System Development Life Cycle: Design

During this second phase besides establishing the requirements for the final product, each member of the team has to understand their roles and tasks. The primary purpose of SDLC is to deliver a high-quality product that meets and exceeds the client’s or company’s expectations. Additionally, it helps companies and teams reduce costs and release software faster by identifying inefficiencies and higher costs and fixing them to run smoothly. This SDLC testing model helps the team to adopt elements of one or more process models like a waterfall, incremental, waterfall, etc. In this type of SDLC model testing and the development, the phase is planned in parallel.

Following all the steps of this lifecycle, you’ll get a detailed plan on how to develop, change, maintain, and replace a software system. The Software Development Life Cycle is a terminology used to explain how software is delivered to a customer in a series if steps. To avoid this situation, first, complete one SDLC cycle, and on the next turn of the cycle, implement the new functionality. Not allocating enough time for the first stage so the customer can clearly and with great detail formulate the requirements for the system. To avoid this error, do not proceed to the following stages until the requirements are written out. During this phase, periodic technical support of the system is carried out to ensure that the system is not out of date.

Understanding this work allows teams to avoid the delivery issues by creating and owning checks and balances early on in our development and delivery life cycle. The development process is almost complete and the software cycle is about to end. When the software solution is completed, the next stage including system testing and integration starts.

At this point, you should have formed an idea of what the system should look like and what it will take to build it. You’ll know what resources are required and set a preliminary budget of time and costs. Systems development life cycle phases include planning, system analysis, system design, development, implementation, integration and testing, and operations and maintenance. Every project manager will find a different approach to these stages of software development.

The final but very important stage of the software development lifecycle is maintenance and regular updates. Development is typically the longest step of the SDLC as it’s the backbone of the whole process. Software engineers have to make sure their code meets all the requirements specifications conforms to the stakeholders’ requirements, and so on. The ready-to-use software is bound to match all the requirements sdlc phases in detail to the software project only in case the previous stages were carefully fulfilled. Actually, scrum and agile come hand in hand because this model is the most popular one. Scrum process iterations or sprints, as they are usually called, last around 2-4 weeks and involve clear scrum frameworks and planning. When the activities have been set and documented, it is almost impossible to add changes.
