software development lifecycle

The SDLC is an imperative factor in software development. Process flaws are often to blame for poor product quality or lengthy delays. As a result, having efficient and best software development lifecycle methodologies and practical project management approaches is essential for projects. This is particularly true for significant, sophisticated enterprises.

In this article, we’ll go in-depth on the  Best Software Development Life Cycle methodologies and provide some tried-and-true advice for improving how one team can use them.

What is the Software Development Lifecycle (SDLC)?

The Software Development Life Cycle is a  method that gives development teams a defined and clear framework for software delivery that allows them to provide the highest-quality software at the most affordable price. The main objective of the software development lifecycle methodologies is to smooth running the design, development, and delivery process of software.

Phases of the Software Development Life Cycle

A few crucial steps – analysis, planning, design, testing, and deployment – are needed to create effective software. Finding the requirements of the end users, gathering the resources, planning the timeline, and developing software all involve extensive teamwork by software engineers. The basic stages of the software development life cycle that almost everyone goes through are as follows:

1. Planning:

It includes identifying the broad objectives and describing the scope and issues with current initiatives. Requirements collecting is the beginning of the SDLC’s first phase. According to project managers and other stakeholders, it is the most significant stage in the whole SDLC.

Planning provides solutions to issues like:

  • What will be the software’s purpose?
  • What information will be entered into the software?
  • What results will the program produce?
  • Who will make use of the software?

2. Analysis:

This involves creating the basic ideas for concepts and gathering all the information required for a new system. In this phase, developers often create a software requirement specification (SRS) document.

3. Designing:

In this phase, developers mainly utilize the criteria in the SRS document as a starting point to generate a comprehensive strategy they may implement throughout the design phase.

4. Development:

The developer starts this process as soon as they obtain the design specification. All software components will be put into use at this stage. On the basis of the designs produced in the previous step, developers will produce the source code.

5. Testing: 

In this phase, Before releasing software, it is carefully tested, and any defects discovered are reported to the developers for resolution.

6. Deployment:

At this stage, the additional features are put into the production phase and made accessible to end customers.

7. Maintenance:

The development team addresses problems and makes enhancements at this stage.

Benefits of Software Development Life Cycle:

  • In doing so, it generates a complete picture of the process in terms of cost, schedule, and timeline estimates.
  • In other terms, it’s a tool for monitoring and controlling ongoing projects.
  • It’s a collection of guidelines for doing things in a certain way.
  • It speeds up development while reducing risks and time lags.
  • As an outcome, all stockholders are able to take part.
  • Outlining everyone’s expected contributions and responsibilities facilitates open lines of communication.
  • Relationships with both internal and external clients are boosted as a result.
  • Without a plan, it is hard to create a successful product.
  • The presence of a plan for software development is more favorable than having no plan. Last but not least, without a set of criteria, it’s impossible to say whether or not a product delivers what’s expected.

Popular Software Development Life Cycle Methodologies:

The strategies and procedures software development teams use to effectively and complete the Software Development Life Cycle are known as software development lifecycle methodologies (SDLC).

There are several models of software development lifecycle methodologies. Each has its own set of benefits and drawbacks.

However, the strategies and methodologies vary across each model; each method aims to enable the development team to provide high-quality software cost-effectively and timely.

1. Agile Software Development Life Cycle:

The Agile development life cycle is a combination of many methodologies. It is very flexible and is built on continual connections within self-managed work teams. These teams are professionals from various fields who provide short projects after each phase. One of the core concepts of the Agile software development life cycle is a face-to-face connection with customers.


  • Decisions are made quickly as a result of continual communication.
  • Risks are reduced as a result of the quick response to and resolution of issues.
  • Simple document management.


  • Many discussions and meetings might lengthen the time necessary for the release.
  • The procedure is tough to plan since the needs are continually changing.
  • It is seldom utilized for large-scale process implementation.

2. DevOps Software Development Life Cycle:

Two developments influenced the development of the DevOps methodology. The first step is to apply Agile and Lean concepts to the operations staff. Second, there has been a broad change in business to recognize the need for collaboration between operations and development employees at all levels of the SDLC process.

DevOps is a phrase that stands for developers and operations. To launch and create highly dependable software products more quickly and creatively, the operations and development teams collaborate.

The DevOps model emphasizes discipline, process improvement, constant feedback, and automation of as many manual development procedures as feasible. The software that is currently being developed receives shorter but more frequent updates.


  • Cost and time spent on unnecessary work and bug fixes are drastically minimized.
  • Increases workers’ commitment to the company
  • When operations and development teams share information about possible roadblocks, everyone benefits from a more streamlined process.
  • quicker rates of success after failure
  • Increased trustworthiness


  • As the software development approach favors speeding up the software development process over security, there is a high risk of security issues, such as spoofing and man-in-the-middle attacks.

3. Iterative Software Development Life Cycle:

In this methodology, the software under development becomes more intelligent and better with each step. The process is repeated until the finished program is in working order.

The Rational Unified Process, sometimes known as RUP, created by IBM’s Rational Software group, is a well-known illustration of the Iterative approach.


  • Enables developers and testers to discover a design or functional faults as early as feasible. Consequently, remedial action may be taken on a tight budget.
  • The capability of simultaneous development planning
  • It is affordable to alter the criteria or scope.
  • Each repetition is simple to control.
  • Easily adjusts to the project’s and customers’ changing demands.
  • Less time is needed for documentation and more time is available for designing.


  • There is a considerable likelihood that problems with system architecture or design will arise since not all requirements are acquired at the outset of the project.
  • Requires more managerial focus
  • Each cycle is stiff.
  • Unfit for minor projects
  • Demands a disproportionately significant amount of resources
  • Highly qualified personnel are needed for skill analysis.


4. Lean Software Development Life Cycle Methodology:

Lean project teams look for opportunities to reduce waste at every stage of the SDLC process. Usually, this entails forgoing pointless meetings and minimizing paperwork.

In reality, the Lean methodology is very similar to the Agile methods, with a few exceptions.

One of the most significant differences between the two SDLC approaches is their respective emphasis on client satisfaction. The Agile methodology puts customer satisfaction at the forefront from the outset. As a result, project teams react immediately to stakeholder input throughout the SDLC process.

On the other hand, the lean approach emphasizes waste removal above everything else. This is done to increase the total value for customers.


  • Effective in integrating teams and maximizing communication across team boundaries. Therefore, it is compatible with the Agile and DevOps approaches.
  • Increases the speed at which more functionality may be delivered.
  • It is suitable as an alternative to modern SDLC approaches developed for big, complicated projects since it is easily scalable.
  • Enables the project development team to have more decision-making authority. Consequently, it raises motivation.
  • Eliminates unnecessary tasks, which saves money and time.


  • Good documentation is required, particularly with regard to business needs.
  • Failure to do so might result in inadequately or incorrectly developed regions related to incorrect documentation.
  • Vary depending on the team.
  • This implies that assembling a skilled staff with expertise is essential.
  • Focus is quite simple to stray.

5. Spiral Software Development Lifecycle Methodology:

The Spiral methodology is becoming more popular among the most adaptable SDLC models. The Spiral approach is often used for larger projects because it enables development teams to create fully customized final products.

The four stages of the spiral technique are continued until the job is finished. This opens up the possibility of continuously improving the product. The four steps are planning, risk evaluation, design, and assessment.


  • Able to incorporate modifications and other features at a later date
  • Cost assessment becomes necessary when the prototype is built in minor steps.
  • Reduced risk via modification and improvement
  • Promotes the use of client comments
  • Enhanced rate of progress and methodical inclusion of new features


  • Needs knowledge of risk management
  • High likelihood of missing budget or timeline objectives
  • Unworkable for small projects
  • Due to the intermediary steps, there is much more documentation.

6. V Software Development Life Cycle Methodology:

The verification and Validation Models are both referred to as the V models. Although it was inspired by the Waterfall model, which performs testing at the conclusion of the project, it varies from the Waterfall model in that it incorporates testing at each step of the development process.

The V model works in a similar way to the waterfall model in that each new stage doesn’t start until the preceding one is finished.


  • The capacity to stop the spread of faults.
  • An excellent match for small projects with well-defined needs
  • Greater likelihood of success
  • Provides comfort and convenience.
  • Proactive monitoring of any flaws
  • Saves a lot of time since testing-related planning and design are completed before any real coding is done.


  • The Waterfall model is much more restrictive.
  • Because the software is built during the implementation phase, no early prototype may be created.
  • If changes are made during development, the necessary requirements and test documents must be updated.

7. Waterfall Software Development Life Cycle:

In a waterfall SDLC, each stage occurs after the previous one. Achieving success in the current phase is require for advancement to the next. All project stages are one-time events.


  • The procedure is well-order and predictable.
  • Possibility of precisely forecasting deadlines and resources.
  • Throughout the system, the criteria are not change.
  • The design phase allows for investigating and managing any possible development difficulties.
  • The model is simple to maintain and monitor since each step has a clear beginning and finish.
  • Because the test cases are already describe in the functional design, the testing process is simple.
  • The needs and results are precise.
  • After the criteria are establish, provide a cost estimate with a higher level of precision.
  • There were no “surprises” at the end.
  • A crucial component of the first requirements collecting step is clear technical documentation.


  • Inflexibility and problems resulting from too severe restrictions
  • Only during the project does testing begin.
  • Before the release, it is impossible to determine the product’s strengths and weaknesses.
  • It takes much longer to complete the final delivery compared to multiple techniques like the Agile model.
  • The planning phase does not consider changes brought on by the company strategies or market impacts.
  • Lacks adaptability After the first consultation, the model cannot accommodate new developments or changes in the needs.
  • During the requirements phase, it is pretty challenging to visualize customer demands in terms of functional specifications.

8. Feature Driven SDLC:

According to the technique’s name, developers construct, design, and deploy the project and its overall model based on a set of features. This model’s software development life cycle features are not software features in the usual sense. Instead, they imitate Scrum user stories or are highly similar to them; for instance, “Finish off the registration procedure.”

  • Setting a target date for the project’s completion is difficult.
  • The success of a project heavily relies on senior programmers and developers.
  • FD approach struggles with small-scale initiatives. There is little documentation, which may sometimes lead to misunderstanding.

9. Joint Application Development:

It is a methodology in which IT experts from a Center of Excellence meet knowledgeable individuals from the sector. Together, they commence the endeavor with thorough preparation. They mould the finished software product according to the criteria and must be acquired during the planning phase. You may include clients in the design phase to help them learn about the project’s growth and development after completing the planning phase.

  • Please make sure the developers you pick for your project have strong interpreting abilities, so they can fully comprehend the project’s needs.
  • Careful preparation might sometimes lead to more incredible prices.
  • During the planning stage, the project has to improve upon the pre-established criteria. Therefore, the product cannot become scalable in the future.

10. Big Bang SDLC Methodology:

The big bang is the shortest and least time-consuming approach from software development lifecycle methodologies model since it has no set procedures and can be implemented without preparation. The time, energy, and materials necessary to create a product under client specifications are pooled in this approach. It’s possible, however, that the final result won’t live up to expectations.

The extensive bang method is often used when just one or two engineers are required to complete the development process. It’s a great way for up-and-coming programmers to hone their craft and earn practical experience. The powerful Big bang technique also saves money since it doesn’t require much extra workforce or supplies.


Selecting from one of the appropriate software development lifecycle methodologies for building any software is crucial and will depend on the project’s specific circumstances and business needs. Making the wrong decision might cause the whole process to advance incorrectly or become an unrecoverable project.

The software development lifecycle methodologies are a method for creating high-quality, inexpensive software as quickly as feasible. The main goal of the SDLC is to develop and deliver good software that surpasses all client requirements and expectations.

Suppose you want a productive and efficient SLDC. In that case, you need to be adaptable, open to recommendations from your group members, implement agile approaches, have a feedback loop from clients, stress security, and be flexible when picking the methods while concentrating on the objectives.
