Flexible design refers to the approach of designing systems, products, or processes that can easily adapt or accommodate changes or variations. This can include designing products with interchangeable components, systems that can be easily modified or upgraded, or processes that can be easily reconfigured. Flexible design allows for greater versatility, adaptability, and scalability, making it easier to respond to changing requirements or constraints. It can also help reduce costs and improve efficiency by minimizing the need for redesign or retooling. Overall, flexible design is important in various industries such as manufacturing, engineering, software development, architecture, and more, where the ability to quickly adapt to changing needs or opportunities is crucial for success.
