Software Development Methodologies: a Comparison of Pros & Cons

What drives the choice of a software development methodology? This choice is always relative to the requirements of a project. In addition to this, project type and size, the skills of team members, financial resources and preferences are also valuable considerations.

Let’s take a look at our top list of methodologies and see why software development companies opt for these software development models.

1

Agile Methodology

Agile development is one of the most popular approaches in the IT world today. Besides that, numerous software production methodologies are based on agile principles. However, they slightly differ. Keep pace, some of them we will describe in this article.

Software Development Methodologies: Agile

By itself, the agile software development approach is mainly focused on a finished product with collaborative efforts. It involves short-term software development cycles called iterations. Each iteration is well organized and similar to a mini software project usually lasting from one to four weeks.

The iterations contain tasks such as adding new functionalities, requirements analyzing and planning, designing, coding, testing, and documenting. As the number of iterations increases, the development team reassesses the project and prioritize the backlog. It is a good practice that helps to ensure the product release and have a better version at the end of every iteration.

Scrum Methodology

Scrum is the most famous Agile software development process framework. It is empirical in nature and can be applied to any fast-changing or priority emerging requirements.

Software Development Methodologies: Scrum

In scrum iterations are named sprints. As a software development process, it kicks off with a brief planning for each sprint, followed by daily scrum meetings that highlights the project progress, and ends with a final review.

Scrum methodology is ideal for managing projects with not well defined requirements and feedback from the client. Teamwork, transparency, and regular status updates allows to speed up the progress of the project.

Feature Driven Development Methodology

This is another iterative methodology but in combination with object modelling. It is effective for large team projects. The first step in this method is reviewing the scope of the system. After the review, next is the creation of domain models in detail for every feature, and then the scope of the system is reviewed all over again.

Software Development Methodologies: Feature Driven Development

The merging of all the domain models leads to an overall single model. Software development with this method involves five processes which are: developing the complete model, making the list of features, planning, designing, and building by feature.

Lean Methodology

Software Development Methodologies: Lean Development

The Lean methodology is focused on the development of low budget software that is change-tolerant. Adapted from lean manufacturing, it maximizes resources by developing software with one-third the trio of funds, human efforts, and production time. The workflow of lean is minimal, and all forms of excesses such as meetings, documentation, and so on are cut.

Extreme Programming Methodology

Extreme Programming or XP also refers to agile methodology. The main aim of this model is to create a fully-functional product and cut the cost of software non-essentialities. It is a perfect fit for complex projects with fixed deadlines and not clearly determined requirements. Continuous planning and testing are one of the core principles here.

Software Development Methodologies: Extreme Programming

Extreme programming is most suitable for creating software in an unstable environment. This method gives the provision for developers to deliver a final product at a lower cost. At the same time, it is time-consuming with a lot of human effort due to the frequent meetings, test-driven approach, and pair programming.

Waterfall Methodology

With its introduction in 1970 by Dr. Winston W. Royce, the waterfall is the most traditional methodology in the IT industry. It is a classic approach and a very popular version of the system development life cycle in software engineering. The project goals are pre-defined for each development phase.

Software Development Methodologies: Waterfall Model

It is linear in nature with all projects progressing in stages. The completion of one stage precedes the other. This methodology is rigid because once a stage is complete, no reversible changes can be made based on new requirements.

Prototyping Methodology

The strength of prototyping methodology is that it caters for all the lapses of the software engineering process. According to this model, developers initially make a prototype of the software solution. They visualize how it will run and prove its function to investors or clients.

Software Development Methodologies: Prototype Model

The developers subsequently make all the needed modifications in readiness for developing the final application. This approach gives room for understanding the requirements of software development and conducting useful business analysis.

Rapid Application Development (RAD Model)

Rapid application development, as the name implies, delivers speedy results with high quality. This method is complemented by the participation of active users in the development process.

Software Development Methodologies: Rapid Application Development

Software product development is made faster and of great quality by using focus groups to gather requirements, prototyping, user testing, reusing software components, continuous reviews, and informal communications.

Dynamic Systems Development Model

In comparison with the rapid application development, the dynamic systems development model possesses similar features. The main principle of this model is that perfect software is achievable through a constant changing process.

Software Development Methodologies: Dynamic Systems Development

Iterative in nature, it is goal-oriented with other major characteristics like flexibility, lightness, and continuous development. With a focus on user involvement, this method aims at the development and provision of software models based on a specified budget and deadline.

Spiral Methodology

The Spiral lifecycle model seems highly sophisticated. It functions by the early identification and reduction of risks in a project. Beginning on a small scale, it encompasses risks exploration and the provision of plans to eliminate such risks.

Software Development Methodologies: Spiral Model

It then indicates if the next level of spiral iteration can begin. In contrast to the waterfall model, the spiral method enables the developer to make changes in the code or design even in the testing stage. It is suitable for most kinds of projects but requires good management.

Joint Application Development Methodology

The Joint application development methodology is most suitable for business software solutions. However, it can be effective for all kinds of development projects.

Software Development Methodologies: Joint Application Development

The development and design stages of software production involve interactive workshops. In these workshops sessions, the software system is defined by the developers and end-user or client.

With special attention on the user stories and use cases, it’s a popular methodology for automating a growing business. Due to the user precipitation in all the stages of production, it’s a favorite for high client satisfaction.

Rational Unified Process (RUP) Methodology

Based on object-oriented and web-enabled program development, the rational unified process methodology is considered as a modern approach. It functions by splitting the process flow into four different parts. These parts are namely analysis and design, business modeling, deployment, and implementation.

Software Development Methodologies: Rational Unified Process

Developers are facilitated with specific tools such as templates, guidelines, and sequential processes with examples for all the stages in the software development process. This approach constantly monitors the quality of software created and controls applied changes.

Velvetech’s Top Software Development Methodologies

Based on what we’ve covered, what are your preferred software development methodologies? We at Velvetech prefer to work with Agile, Lean, and Scrum. Those modern methodologies have come to replace good old Waterfall and RUP (Rational Unified Process) models.

Let’s see how Agile, Lean, and Waterfall fare against each other when employed for mobile and web project development.

Differences between Agile and Lean

The big secret nobody is saying out loud is that there are no differences between Agile and Lean. Both software development models focus on delivering product as fast as possible, with the best possible quality that the market justifies with growing demand.

Differences between Lean and Waterfall

The Waterfall and Lean models are as different as a mole and a gazelle. By the time the mole digs up a tunnel, gazelle has been all over the place, and there’s no market for the mole. That’s because the Waterfall methodology focuses on the result at the initiation of the project, and the Lean methodology keeps checking the market-product fit throughout the development process.

Differences between Agile and Waterfall

Agile and Waterfall are different in the same way as Lean and Waterfall because as we’ve established, there’s no real difference between Agile and Lean. And since Lean and Waterfall differ with interim steps and pace of the project — the same goes for Agile vs. Waterfall.
