People nowadays have control over anything and everything at the tip of their fingers, which has aided technology’s rapid development. And all of this is made possible by the software development sector. It’s an unending field with a phenomenal rate of growth and invention. Software developers assist firms in going online and providing services through the use of customized systems. For this, the software development team use a variety of approaches, which we will learn about in this article.
We’ll study a little about software development before diving into the various software development approaches.
What is Software Development?
Software development is the process of building a computer application that assists users in performing their daily duties more efficiently. It’s known as the Software Development Life Cycle, and it has various phases that give developers a way to create a product that meets user and technical requirements. Apart from that, SDLC is a procedure that establishes an international standard that the majority of software development firms can utilize to design and upgrade computer program. By following a few procedures like designing, building, and maintaining high-quality software, software engineers have a set structure for developing some fantastic solutions.
What is Software Development Methodology?
The software development methodology is a straightforward way for creating a system that is used by software development firms. It’s essentially the same as a design and development period. It is a term used to define the software development life cycle. The software development process is essentially a system of communication that has been defined. This indicates that there are rules that a group of individuals follow to determine what work will be done and how it will be done.
Top Software Development Methodologies to Adapt in 2021
1. Waterfall Model
A waterfall is a traditional software development method. Since Dr. Winston W. Royce introduced it in 1970, it has become a classic in the IT sector. In the realm of software engineering, it’s a method based on a popular variation of the system development life cycle. The project goals are pre-defined for each software development step in this strategy. It is a linear project progression strategy in which the completion of one stage leads to the completion of the next.
Advantages of Waterfall Methodology
- It is a simple strategy with low complexity, and it requires very little knowledge to use.
- Process that saves time.
- Testing is a simple process.
- Because it has independent review processes, the waterfall is an easy-to-manage paradigm.
- It’s a good strategy to use, especially for minor jobs.
- Each stage of development has a set timeframe.
Disadvantages in Waterfall Methodology
- With waterfall, developers are unable to construct maintenance projects.
- When the criteria are well-defined, this method is applied.
- After the last step of development, the software is ready to use.
- There are no adjustments or edits allowed after the project is completed.
2. Agile Methodology
Agile is the polar opposite of waterfall development and is one of the most widely used methodologies in software engineering. Furthermore, several software development strategies based on agile approaches exist. However, there are minor differences between them. The agile methodology focuses on completing the product through collaborative efforts. Agile employs an iterative development process in which each iteration is meticulously organized. Iterations consist of tasks such as evaluating and planning requirements, adding new functionalities, designing, developing, testing, and documenting. The development team prioritizes the backlog based on the number of iterations.
Advantages of Agile Methodology
- Because minimal iterations are involved, Agile produces high-quality results.
- It is not dependent on the original documentation, and there will be no setbacks if any risks are taken as the development process progresses.
- It allows developers to improve and alter software in a creative way during the development process.
- The software development process’ costs and budgets are carefully planned with Agile.
- Clients, personnel of the production process, and software engineers all engage on a regular basis.
Disadvantages of Agile Methodology
- At the outset, the product specification does not provide a clear picture of the project.
- The documentation process is inefficient.
- When a developer uses an Agile strategy, there are no strict project deadlines.
- The most difficult aspect of Agile is estimating the resources needed for a project.
3. Rapid App Development Model
The rapid application development (RAD) technique is based on the idea of delivering high-quality software at a faster rate. It’s a process that’s complemented by active users who are involved throughout the development process. By focusing on the requirements acquired by the team, prototyping, reusing software components, user testing, informal communications, and ongoing reviews, the software solution for the client’s business is built at a faster rate.
Advantages of RAD Model
- The functions are built individually and then merged into the project under the RAD manner. The developers reduce the risks of errors by using this strategy.
- Customer feedback is critical in this strategy since it helps the development team enhance the software’s quality.
- This strategy necessitates regular testing in order to avoid major problems.
- The owner of the company has continual access to the development process.
Disadvantages of RAD Model
- For projects with a limited budget, rapid application development is not the best option.
- RAD is beneficial to projects with system architectures that can readily fit into the system’s modules.
- It requires a group of specialists with extensive experience and the ability to quickly identify and design the client’s project requirements.
4. Spiral Methodology
The Spiral model is quite sophisticated, and it focuses on detecting hazards early in a software development project. Because this is a small-scale methodology, it is surrounded by risk exploration and risk mitigation plans. The spiral model then shows whether or not the next level of iteration may commence. It’s a mechanism that allows software engineers to make changes to the code or design while it’s still being tested. As a result, it’s appropriate for a wide range of applications.
Advantages of Spiral Methodology
- A risk analysis method is used in the spiral model, which results in very low hazards.
- Even towards the end of the development process, this strategy allows the developer to add functionality and features.
- It is a successful strategy for constructing large, high-risk enterprises.
Disadvantages of Spiral Methodology
- When the risk factor in a project is modest, a spiral model should not be employed because it wastes resources.
- The danger aspect in spiral development process is that it starts off inconclusively, resulting in conclusions that aren’t conclusive.
- The risk analysis determines whether or not the project established using this method will succeed. The software can fail if there is a problem with the analysis.
5. Scrum Model
Scrum is one of the most popular Agile project management approaches. It’s a methodology that can be applied to projects with high-priority, rapidly changing requirements. The interactions in this paradigm are referred to as sprints. Furthermore, under this strategy, the development process begins with good sprint planning and continues with meetings that highlight the project’s progress. It’s a model that works effectively for projects that don’t have well-defined requirements and work based on client feedback.
Advantages of Scrum Model
- The project’s primary choices are made by the scrum development team.
- It aids developers in quickly identifying problems and allowing the team to focus on the issue after a few brief meetings.
- The daily meeting can assist the team in increasing productivity and making necessary modifications.
- Because they may provide feedback after each sprint, business owners are an essential part of the project’s production cycle.
- Scrum is a customer-driven method that is both flexible and adaptable.
Disadvantages of Scrum Model
- When the development team lacks sufficient knowledge of software development, the scrum technique is not the best option.
- For large projects, this strategy is ineffective.
- The two key factors that determine whether a project succeeds or fails are the estimated project development time and costs.
Software development techniques are an important aspect of the project creation process since they allow developers to create unique software that meets the needs of the client. All of the approaches presented in this blog are excellent at what they do, but picking one to choose for your next project is entirely dependent on the project’s type, budget, and resources. Take your time learning about different models before deciding which one is best for your software development project.
