Iterative Software Architecture: Need of Iteration in Your System Architecture as Your Startup Grows

Iterative Software Architecture

We all know Darwin’s theory of ‘Survival of the fittest.’ A theory that conceptualizes that we have to adapt as we learn and grow. Growing your business involves a similar cycle of ideation, designing, testing, and refining for software development. A continuous process that involves learning, iterating, and evolving to the changing business needs and technological advancements.

The current market scenario is highly competitive, with a new digital product being bombarded every day. How do you gain traction in this overcrowded market? Most start-ups look for a foolproof strategy for designing their products. But does such an approach exist? Read on to know more!

Use Iterative Design in Product Development

While laying the Foundation of your startup, you must have come across or even utilized frameworks like Scrum and Rational Unified Process (RUP). These frameworks were early versions of ‘Iterative Programming’ that came into place to fill in the limitations of the waterfall and other stage-gate methods. Later, all these frameworks were unified in the Agile Manifesto to create the most used iterative approach of today – the Agile method.

When you are ideating a product or business with an iterative design process, it means you want to remain flexible to create or refine your idea instantaneously at any phase of your design process. The first step is to ask, ‘What problem will my product solve’? To answer this question, you must research the needs and expectations of your end users.

The next step is to develop your idea into a prototype that can be tested on the market, analyzed, and refined until you meet the set expectations. However, if you want to reap the true benefit of iterative design, you must repeat this loop to match your customer expectations. It is an incessant process; one example is IBM, which began using an iterative model in computer system design in the 1970s but continues to utilize the same approach to date.
