The process of software development services goes through a series of stages in step wise fashion that almost every developing company follows. Known as the ‘software development life cycle,’ these six steps include planning, analysis, design, development & implementation, testing & deployment and maintenance. Let’s study each of these steps to know how the perfect software is developed. Because the software development lifecycle model requires the development team to complete each phase before moving on to the next, it helps ensure problems don’t become compounded during the process.

  • The testing stage is basically helpful to ensure the quality assurance factor of the software developed for the client.
  • Among all the software development life cycle examples, the Waterfall model is the most client-facing option, giving them extensive control over the project.
  • This is because as defects or problems are found within the software or system it is noted and sent back to the development phase for a solution.
  • Coverity SAST- Analyze source code to find security vulnerabilities that make your organization’s applications susceptible to attack.
  • Once the analysis is complete, the step of designing takes over, which is basically building the architecture of the project.

This is more difficult with the SDLC framework because the team agrees early on to follow a specific development plan. With the software now live and being used by customers, the development team’s focus will shift to maintaining it. DbForge Studio comes with an advanced entity-relationship diagram design tool aimed at designing database schema diagrams and visualizing your database as an Entity Relationship Diagrams .

Then designers prepare several high and low-level design diagrams for developers. After the development stage is over, testing experts examine the solution’s consistency with the project’s Software Requirement Specification. SDLC models define phases of the software cycle and the order in which those phases are executed. The 7 phases of Software Development Life Cycle are planning, requirements, design, development, testing, deployment, and maintenance.

Whichever model you choose, we are ready to offer convenient tools that help automate each stage. Devart offers Database Compare Tools to handle database changes in the most efficient way. The model adds flexibility to the development and allows altering the plan as you go. The Agile model allows you to promptly receive up-to-date feedback from the users and adjust the development according to it. Since the end-user is involved in the task at all times, it is hard to plan and predict the development course.

SDLC is a series of steps for developing, improving, and sustaining a software system. Product lifecycle management refers to the handling of a good as it moves through five typical stages of its lifespan, from development to decline. Coca-Cola discontinued Tab in 2020, along with other products that were underperforming.

Meta may be in the maturity phase heading into decline or stability, according to various sources, including GWS Technologies. You don’t have to worry about the tedious process of hiring developers on your own. Additionally, if an issue comes up that needs to be fixed, the developers should be informed in order to provide fixes depending on their severity. The product may need a hot-fix, meaning a fix for high-priority features that should be done as soon as possible, or otherwise, just wait until the next version to apply the updates.

System Testing And Integration

DbForge Studio for MySQL provides you with the ultimate MySQL database design tool –Database Designer– which helps you handle a number of operations. In the V-shaped model, the development branch is mirrored by the testing one. These branches form two interdependent processes and allow to eliminate many risks and improve the quality of the final product. Software development life cycle steps are loop-structured and never-ending. Constant evaluation of a finished product makes the process more agile and adaptable, alive and breathing.

place the stages of the systems development life cycle in order:

The building phase takes the code requirements determined earlier and uses those to begin actually building the software. The coding phase includes system design in an integrated development environment. It also includes static code analysis and code review for multiple types of devices. This goes on until the customer is satisfied and their needs have been met.

Software Development Life Cycle Tutorial With Examples

Beyond product life cycles, finance and economics are full of other life cycles, which can often mean a series of overlapping themes. For instance, it is common to hear of a business cycle, economic cycle, or even an inventory cycle at a more micro level. A tester’s main role is to contrast the output with the requirements and identify the issues. They make sure that the software product behaves exactly as defined in the requirements. Testers can do this process by following test scripts or test cases for a more structured procedure. They may also do exploratory tests by playing with the features available.

This can save money and time when it comes to meeting deadlines and launch dates. Another advantage is the ability to stay up-to-date on current web development industry trends through the feedback of your customers. The life cycle follows the development of the software from the planning stages to operation and maintenance.

What Is The Software Development Life Cycle?

However, they can be useful in determining the needs of the customers. Effectively each segment builds on the functionality and features of the previous segment with customer input and feedback every step of the way. Because of the risk of interrupting business operations during the install, this phase will usually occur during non-peak hours. This is because of the potential for any errors with integration or transfer.

After these, the whole team will determine the best design approach for the product. Synopsys enables you to add security testing to an existing development process, thereby streamlining security throughout the SDLC. Synopsys solutions help you manage security and quality risks comprehensively, across your organization and throughout the application life cycle. After the product is release-ready, the next action in the order of software development life cycle steps is to display the finished software solution to the client.

Iterative And Incremental Model

The product becomes available to the clients during the implementation phase in SDLC. By examing the life cycle of a product or service, a company can take different actions depending on the cycle the product or service is in. In addition, profits may dip, or an owner may consider selling the business. Growth can still happen when a product hits maturity, but a more mature firm with older products may be more likely to issue dividends than firms in the other phases. Other types of cycles in business that follow a life cycle type trajectory include business, economic, and inventory cycles. The testing phase would take an additional time buffer since this phase needs to allocate time for bug fixes and issues that have been found.

An increase in competition is probable, and cash flow may be coming from profits, bank loans, and partnerships. A life cycle in business follows a product from creation to maturity and decline. This phase is also the end of the initial part of the development process before moving on to integration and testing. Managed SAST- Synopsys Managed SAST enables you to quickly and cost-effectively implement and scale static analysis to systematically find and eliminate security vulnerabilities found in source code.

What Is Software Development Life Cycle?

The team sets the entire product-development plan according to the initial requirements-gathering and analysis. However, this first phase can lead to a failed product if the team doesn’t properly assess the market’s needs. This includes compiling requirements, studying user personas, and agreeing on the product’s purpose.


The planning phase encompasses all aspects of project and product management. This typically includes resource allocation, capacity planning, project scheduling, cost estimation, and provisioning. As for other stages, both the developers and quality assurance engineers should approach their work with potential security issues in mind. Meanwhile, the deployment stage should use state-of-the art intrusion detection systems. First, the team working on the project conducts a preliminary analysis to discover the aims and issues of their client.

These could include the overall system performance, user experience, new security vulnerabilities, an analysis of bugs or errors in the system. Expectations are clearly defined during this stage as well; the team determines not only what is desired in the software, but also what is NOT. The tangible deliverables produced from this phase include project plans, estimated costs, projected schedules, and procurement needs. First, teams should identify policies and criteria that would guarantee the solution’s security at the very beginning .

While the goal is to minimize these errors, they can occur and when they occur during peak hours the company can lose out on productivity and revenue. Again, just as it sounds, this is the phase when the new system is implemented into normal business operations. The new software or system is installed requiring more code to be written as well as moving of any files or data to the new system. place the stages of the systems development life cycle in order: 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.

Origins Of The Software Development Lifecycle

Through this, testers can contribute by adding value to the analysis of requirements. Waterfallrepresents the oldest, simplest, and most structured methodology. Each phase depends on the outcome of the previous phase, and all phases run sequentially. This model provides discipline and gives a tangible output at the end of each phase. However, this model doesn’t work well when flexibility is a requirement. There is little room for change once a phase is deemed complete, as changes can affect the cost, delivery time, and quality of the software.

Managed Services- Synopsys Managed Application Security Testing offers the solution for applying AppSec testing effectively across your full application portfolio. Accelerate and scale application security testing with on-demand resources and expertise when you lack the resources or skills to achieve your risk management goals. With modern application security testing tools, it is easy to integrate security throughout the SDLC. Beyond software development life cycle examples, let’s look at arguably the most important practice in our area of interest today.

The initial concept and creation of the SDLC only addressed security activities as a separate and singular task, performed as part of the testing phase. The shortcomings of this after-the-fact approach were the inevitably high number of vulnerabilities or bugs discovered too late in the process, or in certain cases, not discovered at all. Today, it is understood that security is critical to a successful SDLC, and that integrating security activities throughout the SDLC helps create more reliable software. In practice, Waterfall Model SDLC starts after receiving the list of terms and conditions from the client, which is commonly reflected in a Customer Requirement Specification . Based on it, the analytical, financial, and technological departments summarize the project in a Software Requirement Specification .

The framework creates a structure that enables the development team to produce quality products by adhering to the definition of various tasks that need to be done. With the adoption of faster and newer development life cycles, organizations are moving away from older SDLC models . With ever-increasing demands for speed and agility in the development process, automation has played a key role.

In other words, an agile organization can successfully adapt the SDLC framework to its development model. Because SDLC is a linear model, and the organization does not advance to the next step until the current step is complete, this approach creating information silos. This means the product will be generally available for customers to buy and use.

Here end-users have the ability to fine-tune the system to better suit future needs. Once all requirements have been met by the system the tester will pass the system or software onto the next phase. Depending upon the scope and size of the problems with the system this could take anywhere from a few days to a few months to occur. There is a couple of different ways testers can test systems and software. Studying the ability of proposing alternative solutions after meeting with clients, suppliers, consultants and employees.

Here, the Waterfall model uses a Business Requirements Specification that helps teams evaluate each step. While some software development companies still offer this model of cooperation, this type of a software development life cycle is less popular than other, more flexible models on our list. After all the preparations on previous stages of software development life cycle are completed, quality assurance engineers start scouting for bugs. Testing is another crucial step among the SDLC life cycle phases as it allows for fixing critical problems before they will lead to critical loses.
