What is agile methodology, and how does it work?


Today, it appears that every technological company uses the agile process for software development, or some variation of it. They think they do, at least. Whether you’re new to agile application development or have been learning software development for decades utilising the waterfall methodology, the agile methodology has at least touched your work today.

But, what exactly is agile methodology, and how should it be used to software development? In practise, how does agile development vary from waterfall development? What is the agile SDLC, or agile software development lifecycle? What is the difference between scrum agile and Kanban and other agile models?

The waterfall approach era is over.

For those of us who have been around a while, the waterfall methodology was once the gold standard for software development. Before any coding could begin, the software development process necessitated a large amount of documentation. Someone, generally the business analyst, first drafted a business requirements document, which detailed everything the company required from the programme. These business requirement documents were lengthy, containing information such as overarching strategy, detailed functional specifications, and visual user interface designs.

Technologists generated their own technical requirements paper based on the business requirements document. The application’s architecture, data structures, object-oriented functional designs, user interfaces, and other nonfunctional needs were all established in this document.

The shift from traditional software development to agile software development

The waterfall methodology was innovative when it was first introduced in 1970. It provided discipline to software development by ensuring that there was a clear requirement to follow. It was based on Henry Ford’s 1913 assembly line innovations, which offered certainty at each step in the manufacturing process to ensure that the finished product matched what had been specified in the first place.

The Agile Methodology’s Roles

The users are always defined and a vision statement on the scope of challenges, opportunities, and values to be addressed is always documented in an agile software development process. This vision is captured by the product owner, who collaborates with a diverse team (or teams) to bring it to life. The following are the roles that each person plays in the process.


The user or client is always at the centre of agile procedures. Today, we frequently employ user personas to depict various roles in a workflow that the software supports, as well as various sorts of consumer wants and behaviours.

Owner of the product

The agile development process starts with someone who is expected to be the customer’s voice, as well as any internal stakeholders. To establish a product vision, this person distils all of the insights, ideas, and feedback. These product visions are frequently brief and basic, but they nonetheless offer a picture of who the consumer is, what values are being addressed, and how to answer them. “Let’s make it easy for anyone with internet access to find relevant websites and webpages using a simple, keyword-driven interface and an algorithm that ranks reliable sources higher in the search results,” I assume Google’s original idea was.
