Today more and more startups are opting for Agile development to streamline project management and highlight business value.
Agile proposes an iterative approach to software design and development. The methodology involves the constant changes that occur in development. They allow teams to break down lengthy requirements and development stages into smaller parts. Thus, the software is delivered quickly and more frequently.
The iterative model is a part of the software development life cycle (SDLC). This post covers the core process workflow that takes place during an iteration as well as the most vivid pros and cons of the iterative approach. Let’s dive in!
Iterative Development means a software development approach aiming to break the dev process into smaller elements. Each part of this breaking is called “iteration” and represents the whole development process, including planning, design, development, and testing phases.
According to the iterative approach, features are added one-by-one, increasing functionality from cycle to cycle (unlike in the Waterfall model). This model is primarily focused on a simplified implementation that gets more complex as it comes toward the final version.
The iterative model is about gradual improvement. It means that developers need to repeatedly go through planning, design, coding, testing and evaluation stages to rework the product or add extra functionality. Frequent releases help to gather feedback and improve the product to meet the requirements.
All Agile software development projects are iterative because they allow for repeating development activities and revisiting the same work products. They are also structured around the iterations of fixed calendar dates.
The history of iterative development begins at least a few years before the history of Agile.
As we’ve mentioned above, the traditional Waterfall model is focused more on the strict step-by-step development stage’ process. The iterative model contains cyclical processes.
At first, you plan. Then a small set of stages is repeated over and over. All enhancements within the model can be quickly recognized and implemented throughout every iteration that lets the next iteration to be better than the previous one.
All projects in any software development company start with the initial planning. At this stage, specification documents are mapped out, required software or hardware requirements are established, and all preparations for the upcoming stages are discussed.
After the planning phase, the team performs an analysis to choose the proper business logic, database models, and so on. Next, the design stage comes, and the team establishes tech requirements.
This stage is about the actual implementation and coding processes. All specifications and design docs should be accurately created by this phase.
Developers go through a range of testing procedures to identify any potential bugs or challenges that have appeared.
This is a time for a thorough evaluation of development. It means that the software development team and customers require examining where the project is and where it must be at the moment.
Iterative development is often hailed as the perfect solution for young ambitious projects with limited budgets, because the model provides a chance to bring software to the market quickly and gradually make improvements over time.
However, thinking about the iterative approach, you’ll definitely need a highly skilled development team able to protect the project from risks and stalling.
