What Is SDLC? Understand the Software Development Life Cycle

Thông tin chi tiết

The SDLC life cycle process is repeated, with each release adding more functionality until all requirements are met. In this method, every cycle act as the maintenance phase for the previous software release. Modification to the incremental model allows development cycles to overlap. After that subsequent cycle may begin before the previous cycle is complete. Once the requirement analysis phase is completed the next sdlc step is to define and document software needs. This process conducted with the help of ‘Software Requirement Specification’ document also known as ‘SRS’ document.

It is more commonly used for large scale projects with many developers. After training, systems engineers and developers transition the system to its production environment. This may involve training users, deploying hardware, and loading information from the prior system. Conduct with a preliminary analysis, consider alternative solutions, estimate costs and benefits, and submit a preliminary plan with recommendations.

Software Requirement

Standard and transparent processes help the management of large teams. LogRocket identifies friction points in the user experience so you can make informed decisions about product and design changes that must happen to hit your goals. With LogRocket, you can understand the scope of the issues affecting your product and prioritize the changes that need to be made. LogRocket simplifies workflows by allowing Engineering and Design teams to work from the same data as you, eliminating any confusion about what needs to be done. The engineers receive the requirements and the design from the other team members and the actual implementation work starts.

What are the 5 SDLC models

With an idea to create an intuitive melody search tool, the MindK team initially built a Proof of Concept – an app that performed great on various devices. You understand that the product is worth improving and offering to a wider audience. To make that happen, you collect a list of improvements and new features that will make the product valuable to a wider audience. We’ve already explained how to take the maximum value out of MVP in our previous article on how to do the MVP right. When the trial version is ready, you test it in the narrow circle of colleagues, partners, or those whose opinions you can trust.

What’s the Difference Between SDLC and Project Management?

The designers pass the requirements to create a very detailed prototype that covers every aspect of the user journey. The prototype should cover all possible cases, including error messages, status, and interactions. They use the SDLC alongside the engineering manager to organize their workflow. However, the SDLC is also a part of the holistic product development framework. Unit, system, and user acceptance tests are typically performed.

It has various spirals in its diagrammatic representation; the number of spirals depends upon the type of project. Each loop in the spiral structure indicates the Phases of the Spiral model. Keep fine-tuning your lean processes until you strike the right balance. Some organizations struggle to adapt to lean methodologies because it’s so different from the way business is normally conducted. The key is finding a balance between elements, such as enough documentation and too little, to properly guide software coding efforts. This includes reducing any meetings, process steps, and administrative overhead to only those absolutely necessary.


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 first step in the software development life cycle is planning. It’s when you gather the team to brainstorm, set goals, and identify system development life cycle risks. At this stage, the team will work together to devise a set of business goals, requirements, specifications, and any high-level risks that might hinder the project’s success. The software development life cycle (SDLC) is an important framework for organizations delivering software products.

  • Testing your software ensures you catch issues before exposing your end users to the product.
  • The system typically consists of several hardware and software components that work together to perform complex functions.
  • At this stage, the fundamental development of the product starts.
  • SDLC achieves these apparently divergent goals by following a plan that removes the typical pitfalls of software development projects.

There are different models, each of them having its strengths and weaknesses. In this article, we will get acquainted with the main types of SDLC models, their specifics, positive and negative sides. Looping takes place in this step, and better versions of the prototype are created. These are continuously shown to the user so that any new changes can be updated in the prototype.

Incremental Model in SDLC

This allows developers to break large systems into smaller components, building one feature at a time. The main characteristic of this model is that it allows a company or a startup to navigate the fast-changing business environment. This means you don’t need to define a complete list of requirements and create a detailed specification in advance, like in the Waterfall model.

The software development lifecycle (SDLC) is the cost-effective and time-efficient process that development teams use to design and build high-quality software. The goal of SDLC is to minimize project risks through forward planning so that software meets customer expectations during production and beyond. This methodology outlines a series of steps that divide the software development process into tasks you can assign, complete, and measure. To create high-quality software, you need a process in place that helps you manage your time and resources.

The agile model was mainly designed to adapt to changing requests quickly. The main goal of the Agile model is to facilitate quick project https://www.globalcloudteam.com/ completion. These processes have some similar characteristics but also possess certain subtle differences among themselves.

It allowed us to develop an event management module in a short timeframe. The client needed this functionality as soon as possible because of the pandemic. The event module allows to easily arrange online and offline courses, conferences, meetings, and other activities.

What Are the Benefits of Implementing an SDLC?

The use of SDLC enables programmers to work concurrently and evaluate each part of the software development process effectively. It is important to note that SDLC is a process and not a technique. The SDLC framework ensures proper planning goes into your software development process. The end result is a higher-quality product and experience for your users. Over the years, the SDLC model has included the development phases planning, analysis, design, implementation, testing, deployment, and maintenance. You might find slight variations in different places, but they all amount to the same phases.
