Bottom-up design

Bottom-up design is a systematic approach to software development that begins with smaller, more manageable components or modules and gradually combines them into a complete program. Unlike top-down design, which starts with an overarching structure and breaks it down into smaller parts, bottom-up design focuses on refining individual elements first. This method allows developers to address detailed functionalities and interactions at a granular level before integrating them into larger structures. By emphasizing modular development, bottom-up design promotes flexibility and scalability, making it easier to adapt and expand software systems over time. This approach is particularly effective for complex projects where precise functionality and component interactions are critical to the overall success of the software.
