Top 5 Software Development Methodologies in 2021
Today tech is evolving rapidly and force software development companies to compete and work in highly competitive environments. Software development methodologies are a process or series of a process that is involved in development. Development methodologies are an essential factor in the software development industry.
There are various software development methodologies available to build different types of appa. Choosing the right one is crucial to develop the project within the specific time frame with the best results. Before starting a software development journey, it is essential to understand the various development methodologies and their advantages and disadvantages. This article will compare the top software development methodologies to identify which method will be the right fit for your functional and business requirements.
What Is Application Development
Designing, developing, and Implementing software applications is known as Application Development. Companies do software development with enormous resources like coders, designers, testers, and more, Who work on multiple projects. Application development follows some mythology on the development process. Many factors are involved in application development. The software development lifecycle (SDLC) primary stages are planning, analysis, design, construction, testing, implementation, and support.
Kinds of Software Development Methodologies
To manage the project and make the project successful, the development team or project managers must choose a development methodology that works best. All the project management methods have their strengths and weaknesses. Let us look in detail at the top techniques that you can adopt for your project.
Agile Development Methodology
Agile is a more popular software methodology that concentrates on adaptive planning, evolutionary development, and continual improvement through flexible response to change. The main aim of this methodology's goal is to provide early software release with a lower chance of errors or bugs.
Agile promotes the continuous iteration of development and testing throughout the development cycle. In the agile method, development and testing are concurrent. This method minimizes the risks like bugs, cost, and more while combining new features or functionality on the application. There are numerous agile development methods like extreme programming (XP), scrum, crystal, and feature-driven development (FDD). The most widely used two agile methodologies are Scrum and Kanban.
Today Agile methodology is rapidly spreading among all types of companies. According to a Deloitte report, 80% of major IT projects are now using “Agile” or “iterative”. This method allows the programmer to build the product more timely and productively. Agile is more flexible, and it is a team-based development approach.
In this method, the development works separated into different phases, and it is known as sprints. Each sprint will last for a few weeks, and the project development team members will follow a list of deliverables for that particular sprint. At the end of the sprint, the Scrum master and the team members review the works together.
Agile Development Advantages
Agile Development Disadvantages
The waterfall model is the most traditional and commonly used development methodology. Winston W. Royce introduced the waterfall model in 1970. It is a classical cycle of application development, and the Waterfall approach is a sequential model that divides building into predefined phases. Each phase must be completed before the next step can begin with no overlap between the stages. This development approach doesn't permit us to get back to previous phases if any changes are needed.
The Phases of the Waterfall Model
The waterfall approach has 5 to 7 stages in the development cycle. The developer can't initiate the next phase until the previous step is completed.
Waterfall Model Advantages:
Waterfall Model Disadvantages:
DevOps Deployment Methodology
The term "DevOps" is a blend of the words development and IT operations. DevOps is a newer methodology, it is a succession to agile, and DevOps is not a replacement of Agile. This software development methodology aims to bring software development teams and information technology to succeed in the product. It emphasizes ongoing collaboration across all stages of development instead of dividing the roles and responsibilities. It removes the barriers between the development team and the IT operation team. DevOps methods are based on cross-functional teams association to make the project development smoother, effective, and prevent bugs. DevOps methodology creates inter-team cooperation.
The DevOps lifecycle comprises seven phases as provided below:
Drawbacks to DevOps
Rapid Application Development
The rapid application development model in which the application is developed based on prototyping without any detailed planning. RAD is a useful methodology that provides more accelerated development and higher quality results than other software development methodology. The RAD model prioritizes more on the development task, and there is less concentration on planning. This method aims to accelerate the entire development cycle (i.e., developing software in a short period. Active user participation in the development process creates goals quickly.
The RAD involves the following 4 phases.
RAD model Advantages
RAD model Disadvantage
The prototyping model is another application development methodology in which a prototype is created, tested, and revised until an agreeable prototype is accomplished. The prototype is the core for the development. This methodology works best in situations where the project requirements are not known in detail. It is a trial and error method that takes place between the client and the software programmer.
Prototyping Model Phases
The Prototyping Model has six following phases.
There are four different types of prototyping.
Cons of Prototyping Model
Feature Driven Development
Feature Driven Development (FDD) is an iterative development methodology approach. It is suitable for large teams and objective oriented technology projects. This model will be ideal for the business that wants to move from phase-based development to an iterative model.
Pros of FDD Methodology:
Cons of FDD Methodology:
The software development methodology is an improvement for any application development. The above overview and the pros and cons of each method will help you understand the development methods and identify the best way that suits your development process. For the desired result, it is essential to choose the appropriate development method initially. Don't hesitate to dedicate the time to objective planning, budget, resource planning, product development, time frame, etc. Software development methodology will help you identify which procedure will best suit you to succeed in the project development.
