Popular Software Development Methodologies in 2024

Advantages

• The Scrum can help teams to complete project deliverables in a timely and effective manner.
• The Scrum ensures that time and money are effectively used.
• The large projects are divided into manageable short bursts.
• During the sprint review, development shall be coded and tested.
• Works well for fast, ambitious development projects.

• Through scrum meetings, the team has a clear view of each other. Scrum, being

Disadvantage

• Due to the absence of a definite end date, the Scrum often leads to scope creep.
• Projects are at high risk of failing if individuals are not committed and cooperative. Adopting the Scrum framework in a big team is difficult.
• Only experienced team members can make the framework work. Some team members are frustrated at regular meetings.

• If any team member leaves during the project, it can have a huge negative impact.

Advantages

Disadvantage

• Kanban lets users make real-time updates, changes, or patches in a project’s flow.

• Scrum has a spring schedule for updating the process and is more flexible.
• The deliverables are shipped as soon as they are developed 
• As soon as the deliverables are developed, they will be sent.
• Kanban is based on the continuous delivery of project results.
• The roles and responsibilities of the project execution are not defined in any way.
• There’s no overhead for meetings or workshops to plan the sprints.
• Kanban’s got a consistent flow.
• Kanban allows you to limit the number of tasks at any given time, ensuring consistency in your workflows.
• Provides Quicker User Feedback

• There is a need for a clear explanation of the roles and responsibilities of certain projects.
• Due to the lack of a clear role, it is very difficult to manage collaboration between different team members, which may lead to unstable execution due to continuous change.
• Due to limitations in its planning, the Kanban method cannot cope with a greater number of project tasks.
• It is not suitable for projects based on timelines.
• Kanban’s difficult to define the targets of a sprint

Advantages

• Scrumban combines the structure and predictability of Scrum with the flexibility and adaptability of Kanban.
• The result is a reduction in lead times due to addressing bottlenecks.
• It forces people to work at a moderate, sustainable pace and prevents interested parties from demanding excessively.
• Increased visibility for interested parties.
• This will increase visibility and make the process more fluid, allowing teams to work at a steady pace.

Disadvantages

• The Scrumban can be more complex than the Scrum or Kanban system alone.
• Scrumban can sometimes lead to confusion of roles and responsibilities, requiring a thorough understanding of both the methodologies and careful planning.
• It may be difficult to implement Scrumban, especially if team members do not know one or both of the underlying methods.
• Additional training and investment in resources may be needed to achieve this.

Advantages

• Using only building space, equipment, supplies, and personnel is less costly.
• The key focus is on lean production. This requires removing dead or expired products and eliminating unnecessary space and human resources expenditures.
• It only meets the demands of a few special and loyal consumers on a schedule, which keeps the consumer happy and satisfied.
• It suggests that we can make progress towards the ideal. Raw materials will be bought and delivered when production requires them.

Disadvantages

• Because of the lack of flexibility, there is a high risk of missing the deadline; sometimes, even a second chance is not given.
• The labor or equipment deadlines are missed due to limited space, which may lead to delays in starting up.
• A lean approach may produce counterproductive outcomes.
• There’s very little room for error left by Lean.

Advantage

• Understanding and using this model is simple. Because of its rigidity, each phase has deliverables and a review procedure.
• Processing and completion of these model phases take place at the same time.
• The phases don’t coincide with each other.
• The waterfall model is a good fit for small projects where requirements are clearly set and well understood.

Disadvantage

• Once the application is in the test phase, it’s very difficult to change something poorly thought through in the concept phase.
• During the life cycle, no working software will be produced before late.
• There is a great deal of risk and uncertainties.
• For complicated and object-oriented projects, it’s not a good model.
• A very bad model for lengthy and ongoing projects.
• It is not suited to projects where the requirements are at a low or very high risk of change.

Advantage

• At another stage, additional functions or changes can be performed.
• As the prototype building is built up in small sections, it’s easier to estimate costs.
• Risk management can be helped by constant or repeated development.
• In spiral development, it is faster, and features are added systematically. There’s still room for customer feedback,

Disadvantage

• There is a risk of being unable to meet the schedule or budget.
• The best way to develop a spiral is by requiring expertise in risk assessment, but it’s also necessary for large projects.
• There is more documentation as it goes through a transitional stage. Spiral software development is not recommended for a small project; it could be costly.

Advantage

• In the design, this model can change.
• Errors are easy to spot. It’s easy to spot the lack of functionality.
• There’s scope for improvement, which means new requirements can be easily addressed.
• In the future, a developer can use it for more complex projects.
• This guarantees a higher level of satisfaction and comfort for customers.
• It’s ideal for the online system.
• At the development stage, it may involve users on an active basis.
• The integration requirements are well understood, and deployment options have been selected at a very rapid stage.

Disadvantage

• It’s expensive to do this model.
• Due to the constant change in customer requirements, it does not have sufficient documentation.
• The requirements can vary too much. In some cases, customers demand that the product be delivered as soon as possible.
• After seeing the initial prototype, customers may not be satisfied or interested in a product.
• There is a certain degree of certainty in determining the number of iterations.
• The analysis of problems may not be complete or inadequate. The complexity of the system may be increased.

Advantage

• Cut back on the time it takes to develop.
• It facilitates customer feedback and ensures that the final product satisfies all stakeholders.
• It allows you to integrate from the beginning.
• We’re experiencing a rapid first review.
• Improve the ability of components to be reused.
• Improves risk management for the end product.

Disadvantage

• It depends on a highly skilled team of developers and designers.
• It can only build modularized projects.
• It can’t be used for low prices because it requires a strong team and individuals to deliver.
• Only projects that require rapidity can use it.
• Due to a large number of stakeholders, this is difficult to deal with.
• Requires a strong team

Advantage

• There is a visible and accountable process in XP.
• Developers are committed to what they’re going to achieve and demonstrate progress.
• The strong side is also constant feedback.
• Listen and make the necessary changes in time.
• With regular testing at the development stage, XP helps to create software more quickly.
• allows software development companies to save costs and time required for project realization

Disadvantage

• This methodology’s lack of code quality assurance measurement is an additional disadvantage for XP.

• This may damage the initial code. If programmers are scattered geographically, XP isn’t the best option.

• Extreme programming focuses more on the code than on the design. It could be a problem because good design is very crucial to software applications

Advantage

1. Collaboration and communication make it easier for teams to communicate more effectively.
2. The rapid deployment of software is due to the simplification and automation of multiple processes by teams.
3. Due to continuous delivery, continuous improvement, and continuous development, early detection of bugs occurs in DevOps.
4. With DevOps, operational costs are reduced due to the automation of administrative tasks.
5. Collaboration with global experts will be more likely.

Disadvantage

• Toolchain complexity.
• Vulnerabilities and breaches can occur since the security team still works in silos.
• Investing in tools and training that are needed for complexity may be expensive.
• Dependency on automation can be detrimental. Implementing Role-Based Access Control (RBAC) is often not applied, so access isn’t specified.
• Periodic permission audits aren’t implemented, and deep checks are lacking on who has permission.

Advantage

• The crystal method is flexible and can adapt to project type, size of team, and requirements for projects.
• Priority shall be given to delivering the project’s critical and important parts.
• There may also be a minimum of ten team members in this project.
• This method facilitates efficient team communication and helps to foster a culture of learning between the members.

Disadvantage

• The principles applied may vary according to the size of the team and the project, making it difficult to understand.
• It requires constant communication, so projects with some working areas may not work well.
• Planning and development are not dependent on the requirement; it is difficult to shift from one approach to another in the middle of the project.

Advantage

• It will include all stakeholders’ knowledge.
• Better work prioritization.
• Greater accuracy.
• It helps to identify problems in advance.
• It makes it easier to adapt your schedule.

Disadvantage

• Complex

Advantage

• The FDD encourages collaboration between team members and breaks the development process into easier tasks.
• FDD makes it easier for teams to create new features and functionality by focusing on small improvements that make a difference in the short term.
• The structured approach of the FDD ensures that team members are fully aware of project objectives and requirements.

Disadvantage

• The FDD needs substantial upfront planning and modeling, which can take considerable time.
• Compared to other agile methodologies, FDD can be less flexible when it comes to changing requirements due to its structured approach.
• Focusing on features is generally beneficial for FDD, but adapting to changing requirements can sometimes be difficult.

Advantage

• SAFe provides the most value when cross-functional teams need to work together.
• Program Increment planning is the framework’s method of clarifying the vision of what the program needs.
• Extending agile practices to capture what is most important to the business will allow the industry to take over the process of reassessing priorities.

Disadvantage

• Initially, SAFe was intended to be used exclusively by big organizations to help them deal with complicated projects.
• The impact of adopting agile practices on businesses is often too expensive.
• With SAFe, many new terminologies will take time for teams to understand and adopt.

Advantage

• JAD gives you the ability to solve your problems more easily and produce software that is errorless.
• All risks are reduced by collaboration between the company and its clients.
• The JAD will reduce the cost and time.
• Progress has been faster because of the tight communication.
• JAD encourages the team to push each other to work faster and deliver on time

Disadvantage

• It’s hard to set goals and keep focus because of the different opinions on the team.
• JAD may require a significant commitment of time, depending on the size of the project.

Advantage

• Potential defects are identified and addressed as soon as possible.
• During the project life cycle, functional prototypes are developed at an early stage
• . It takes less time to document and more time to design. It’s easy to measure progress. The small size of the modules makes it easy to test.
• During the evolution phase, most risks can be identified and higher risks can be addressed at an early stage.
• As milestones, success iterations can be easily managed.
• An operational product is delivered with every iteration.
• Less Operational cost.

Disadvantage

• There may be a need for further resources. Each successive phase is rigid with no overlaps.
• There may be a need for more intensive project management.
• In view of the lack of a complete requirement specification for the whole system, it may be considered as a barrier to systems architecture.
• The end date of the project may be difficult to specify. Risk analysis requires the highest level of expertise.

Advantage

• Implementing the practices already used by the teams in the scrum will reduce the cost of implementation.
• One product owner with knowledge of the framework and principles bridges the gap between business and technical teams.
• Fewer people are needed to deliver a product. Adding more roles and overhead does not exponentially increase LeSS.
• Within the area of focus, it presents a complete product overview.
• Teams shall be directly in contact with the client and business stakeholders.

Disadvantage

• It’s hard to scale.
• Implementing LeSS will be more difficult if your company or team does not know how to use the Scrum gestures and goals.
• Applying the Le SS method efficiently without extensive training in your company may be much more difficult.
• If you have used other methodologies and frameworks for project management or product development over the past. They may be difficult to work with, manage and assist a wide range of teams.

Advantage

• Improves both productivity and effectiveness.
• Cost of real estate and office equipment is reduced.
• By reducing the cost of commuting, this will also help save money for workers.
• With the adoption of new technology tools, they are able to communicate and collaborate from anywhere in the world
