The process that engineers typically follow to solve a problem involves several key steps. Among the options you've provided, the series of steps generally includes:
- Definition: Clearly defining the problem and understanding the requirements.
- Research: Gathering information, studying existing solutions, and understanding relevant technologies or methodologies.
- Development: Creating and refining solutions based on the defined problem and research findings.
- Design: Designing the solution in detail, including specifications and plans for implementation.
Therefore, the correct order can be understood as: Definition → Research → Development → Design. These steps can vary slightly depending on the specific engineering discipline and the nature of the problem, but this sequence captures the essence of the problem-solving process in engineering.
