Software Development Methodologies – How to Choose the Right One?

Choosing a software development methodology has increased traction over the years—no surprise there, as even small projects would fail without the right approach. It is a codified way of communication that describes the “how” of the life cycle of software. But sometimes, choosing the proper methodology to manage a project is challenging as every methodology cannot get well with all kinds of business.

For example, Cisco worked with the waterfall model for their Subscription Billing Platform (SBP). However, this approach created multiple issues for them like slower development, increased overtime, missed delivery dates, quality issues, etc. Thus, Cisco adopted the Scaled Agile Framework (SAFe) to collaborate on building and testing small features within one SaaS component.

As a result, it delivered the new release of SBP to the system integration and testing team without any overtime. Thanks to the collaboration of both these teams, Cisco’s defects were reduced by 40% and defect removal efficiency increased by 14%.

In this article, let us help you choose the best software development methodology by describing its pros, cons, and phases.

What are software development methodologies?

Software development methodologies are the combination of well-structured processes to implement while working on a development project. You can even call it a systematic approach or a defined way to describe the life cycle of every piece of software.

Other than that, software development methodologies chalk out norms for developers or development teams that say how they will work and share information, whether that is documentation, discussion, or even drawings on paper.

Detailed Outlook On Software Development Methodologies

Custom software development companies use Agile Spiral, Scrum, Extreme Programming, Rational Unified Process, Big Bang, etc., to deliver a premium product to their clients. Therefore, it’s natural for them to deploy a combination of software development methods per their team’s needs and stakeholders’ expectations. Thus, using different software development methodologies for various projects is advisable.

Here are some popular methods for software development introduced within the IT landscape to capitalize on various resources –

1. Agile

Agile methodology is an iterative way of transforming a bunch of requirements into software. Constant planning, understanding, communication, development, delivery, and updation are the crucial aspects of the Agile process. In addition, Agile software development methodologies focus on the direct engagement of teams and clients to understand goals better and give timely solutions.

VistaPrint is a marketing company for small businesses. The teams at Vistaprint took 60+ days to take a new idea to a deliverable, but the actual time consumed by developers is only 40 hours. After conducting a root cause analysis, Vistaprint suffered due to unclear decision rights and long creative lead times.

Then it switched to Agile to decrease project lead time. Vistaprint implemented team-building activities, daily stand-ups, Kanban boards, and an idea pipeline. As a result, it witnessed a decrease in Lead Time from 40 to 15 days in just five months of integrating Agile.

Apart from this, there are some other Agile frameworks as well, like Scaled Agile Framework (SAFe), Large Scale Scrum (LeSS), and Scrum of Scrums(SoS). We’ve already discussed how Cisco benefited by adopting the Scaled Agile Framework (SAFe).
