Adapting to change with incremental and modular design for better outcomes
Change is inevitable. It’s a fact of life. We may not always welcome it, but it’s what keeps us on our toes, pushing us to solve new problems and challenging our thinking and approach.
How we tackle these challenges or design problems — because, in essence, every challenge is a design problem, isn’t it? — is entirely up to us. We can stick with the tried and tested methods that have served us in the past, or we can seize the opportunity to view these problems from fresh perspectives, using or creating new methodologies that better address today’s challenges. 
Consider the global issues we face, such as climate change, urbanisation, and health crises. It’s becoming increasingly clear that traditional large-scale project methodologies, like Waterfall, often fall short. While these methods may have been effective in the past, can we truly say they still help us solve today’s design problems as effectively?
One of the things I love about design is its constant evolution. As designers — whether content designers, UX designers, or designers in general — we’re always evolving our approach to solving design problems.
Incremental and modular design methodologies offer powerful alternatives that help us break down complex problems into manageable, adaptable components. However, integrating these methodologies is where we often struggle, especially when up against established systems. So, what strategies can we apply to create more effective and sustainable solutions?
What is incremental design?
Incremental design is a method that implements solutions through small, manageable steps, such as in Agile methodologies. By breaking a large project into smaller parts, teams can focus on achieving short-term goals while gradually working toward a larger objective. This approach allows for flexibility and adjustments based on real-time feedback, bringing the user closer to the design process and adapting to changing conditions.
What is modular design?
Modular design involves creating separate components or modules that can be developed independently yet function together as part of a larger system. Each module has clear inputs and outputs, allowing for easy updates or replacements without disrupting the entire system. This approach not only enhances adaptability but also supports scalability and localisation of solutions.

Advantages of incremental and modular design
Flexibility and adaptability
Both approaches allow for changes and pivots without extensive rework, which is crucial for responding to unexpected challenges or new information.Efficiency
By focusing on smaller parts of a problem, teams can achieve quick wins and maintain momentum, reducing the risk of large-scale project failures.Customisation
Modular design enables customisation and local adaptation, allowing solutions to be tailored to specific needs without overhauling the entire system.Sustainability
Incremental and modular methods can lead to more sustainable practices by reducing waste and allowing for the reuse and repurposing of modules.
Take solar-powered modular homes as an example. These homes are constructed using prefabricated modules that can be easily transported and assembled. The modularity allows for customisation based on the climate and topography of the location, while the use of solar power addresses energy sustainability.
Incremental software development is another great example. Many tech companies, like Google and Amazon, have adopted Agile methodologies, where software is developed in increments. Each part of the project is reviewed and improved upon based on user feedback, enabling continuous delivery of value to their customers.
Implementing incremental and modular design
Implementing these design approaches is not without its challenges. The biggest hurdle is often a shift in mindset. Breaking old habits and ways of working can be tough, and it can be tempting to revert to familiar methodologies. Here are a few steps that might help:
Define clear objectives
Start by clearly defining the goals and breaking the project into modules with specific, measurable objectives.Engage stakeholders early
Include input from all stakeholders early in the process to ensure that the modules meet the diverse needs and expectations of those who will use them.Prototype and iterate
Develop prototypes for individual modules, test them in real-world settings, and iterate based on feedback. This process helps refine each component before it’s integrated into the larger system.Focus on integration
While modules are developed independently, it’s crucial to ensure they integrate seamlessly. Regular integration tests can help identify and address compatibility issues early on.
Incremental and modular design are not just strategies; they are mindsets that require us to think about projects in new ways. By adopting these approaches, designers can tackle all design challenges — even global ones — more effectively, with solutions that are robust, flexible, and responsive to the dynamic needs of our world and users. As we face increasingly complex problems, the ability to adapt and iterate is more valuable than ever.
