The software development methodology process is so complex, complicated, and multifaceted that it calls for well-thought-out planning, implementation, and management. Software development methodology is a collection of die tools, methods, and procedures for software design. These methodologies provide the projects with the belief that they can be finished well within the time limit with good quality. This article focuses on the top ten software development techniques, their benefits, and their effects on projects.

Every methodology has its peculiar way of organizing the software development process. Still, they all share a common goal: to develop successful software products that match the market’s demand. Instruction: Humanize the given sentence. By understanding the various ways and their merits and demerits, you can make the right choice for your project and ensure success.

8 Key Methodologies:

1 Waterfall Methodology:

Waterfall methodology is a linear and sequential way of software development. It consists of distinct phases: analyze the needs, design phase, execution phase, test phase, and maintenance phase. A highly structured and disciplined approach is used in every step, so one phase must be completed before moving on to the next.

Advantages:

• It is meant to provide a clear structure and definition for the development progress.
• Permit to plan a detailed scale and documentation.
• It helps to foresee and prevent risks in the initial stages of the project.

Disadvantages:

• It is a process that needs meticulous planning from the initial stages, which is often lengthy and costly.
• The redesign is not suitable for projects with changing or uncertain requirements.
• They need more flexibility and agility to switch quickly to market changes or customer needs.
• The problem is getting customer feedback and updates during the development stage. – Reference: Design Thinking in Business: Turning Spongeball to The Real Bread | INCAE Business School

2 Agile Methodology:

Agile is an incremental and collaborative methodology that gives frequent minor releases to the software so users can experience new features as soon as possible. It is thus about being adaptive and responsive and keeping the customers at the forefront. Agile methodologies are Scrum, Kanban, and XP.

Advantages:

• Enables flexibility and adaptability to update requirements that are in a changing environment.
• Provides a platform for team members to collaborate and communicate with stakeholders.
• Delivers working software regularly, in small increments.

Disadvantages:

• She demanded a high level of involvement in and collaboration from clients, which is a burden for other organizations.
• That might cause more workload for developers as the development process usually includes modification and improvement cycles.
• Scaling can be time-consuming, especially when scanning more significant projects or organizations.
• Consequently, there are, most likely, scope creep or changes in project requirements, which further affect the overall schedule and budget.

3 Scrum Methodology:

Scrum is an Agile framework where teams work together to accomplish their goals collaboratively and iteratively. It breaks the project into a time-boxed iteration of sprints, typically lasting from two to four weeks. Each Sprint is used for the team’s efforts to implement some features and produce potentially deliverable product increments.

Advantages:

• Teams up members through transparency, accountability, and teamwork.
• Leads to fast information exchange and, therefore, reactions.
• The value proposition should be the foremost thing to emphasize in this situation.

Disadvantages:

• The Scrum Master and the Product Owner are the key members needed daily; hence, this may not be possible in some organizations.
• There may be problems in implementing and scaling across larger organizations with multiple teams.
• That may lead to occupational role overlapping and disputes between team members.
• It may be challenging to stay focused and steady across the Sprint.

4 Kanban Methodology:

Kanban is another Agile methodology that uses visual boards to manage workflow. It allows teams to follow progress, detects bottlenecks, and optimizes efficiency. Kanban gains considerable momentum in ongoing projects.

Advantages:

• Serves for visual depiction of the ongoing work.
• Permits ongoing improvements and refinements.
• It does help to find out the blockages or areas for improvement.

Disadvantages:

• Demands for discipline to maintain the flow and up the issue limit.
• Overloading may occur, leading to bottlenecks if the work needs to be managed correctly.
• Scalability becomes challenging when applied to larger projects or when the numbers get bigger.
• Therefore, this only aids a student to focus or find direction if implemented correctly.

5 Lean Methodology:

Lean is a method that spans around eliminating waste and inventing values. It is an approach that calls for constant improvement, customer mindfulness, and efficient resource usage. The lean method pursues delivering quality goods quickly and should be cheap.

Advantages:

• Emphasis on the reduction of waste and the maximizing of the value.
• Emphasizes excellent performance that is customer-centered and continuous improvement.
• It cultivates an atmosphere of camaraderie and innovation.

Disadvantages:

• A cultural change within the organization is a prerequisite in that the principles of Lean are adopted.
• This implementation and sustainability are complex in practice.
• Such action may lead to resistance or obstruction by employees or stakeholders.
• Such endeavours may require a substantial amount of time and resources.

6 DevOps Methodology:

DevOps is the art of collaboration and connection among the development and operations teams. It intends to smooth and quicken the software development process, improve the number of deployments, and decrease the lead time. DevOps techniques combine development, testing, deployment, and monitoring into a single task flow.

Advantages:

• The feature simplifies the process of cooperation between dev and ops teams.
• Automates and shortens the software development cycle, leading to a shorter lead time.
• It correctly enables the increase in deployment frequency and reliability.

Disadvantages:

• Requires a mindset transition and changing current practices and pipelines.
• It is hard to implement in siloed organizations, which is what we know traditionally.
• It can be met with resistance or backlash from employees, management, or other stakeholders.
• It can be a significant investment of time and means to set up and run it.

7 Spiral Methodology:

The Spiral methodology is an iterative software development approach that combines Waterfall and Agile elements. It consists of four quadrants: planning, risk analysis, engineering, and evaluation. The Spiral methodology allows for iterative development while providing a structured risk management approach.

Advantages:

• Allows for iterative development and risk management.
• Encourages client involvement and feedback at each stage.
• It helps identify and address potential risks early in the project.

Disadvantages:

• It can be time-consuming and costly to manage.
• Requires a high level of expertise to implement and work effectively.
• It may result in delays or missed deadlines if not correctly handled.
• It could complicated to make revisions/updates during the development process.

8 Rapid Application Development (RAD) Methodology: 

RAD is an agile technique that centers on incremental development and rapid prototyping. The main objective is to solve a problem quickly and get early feedback to iterate. The most salient feature of RAD methodologies is that they are time-saving and can be used for shorter timelines or projects with changing requirements.

Advantages:

• It allows building an efficient prototype and experimenting.
• Fosters teamwork between team members and stakeholders.
• Quickly and recursively delivers what an end user can accept.

Disadvantages:

• It has to be highly participatory, consisting of client input and interaction.
• It can get tricky to handle and scale for larger projects or institutions.

Conclusion:

To finish, development methodology is an important choice, which outcome impacts a lot for the project. Every method has a set of strong and weak sides; thus, the project factors and limitations should considered when making a final decision.

The Waterfall methodology is based on a formal, structured, and disciplined approach. Nevertheless, with the problem of changing and uncertain requirements, the method needs to fit the projects. Agile tools like Scrum and Kanban use iteration to adapt and, therefore, can adjust even for changing project requirements.

In conclusion, project success is achieved by properly using the methodology selected with the project team’s commitment and collaboration. The project manager can quickly choose the right strategy to implement a software project development correctly by analyzing the pros and cons of each method.
