What is the activity of collecting evidence of the thinking and problem solving involved in a designed innovation?

The activity of collecting evidence of the thinking and problem solving involved in a designed innovation is accurately identified as documenting. This process involves recording the stages of development, decisions made, and the rationales behind those decisions throughout the design process. Documentation serves as a way to capture the evolution of the innovation, providing insights into the methodologies used and the thought processes behind problem-solving efforts. It plays a critical role in not only showcasing the completed work but also in reflecting on the journey of design, allowing for future improvements and understanding.

In contrast, analyzing typically involves interpreting data or information after it has been collected; brainstorming centers on generating ideas and solutions in a collaborative manner, often without immediate judgement or evaluation; and evaluating refers to assessing the success or effectiveness of a design after it has been implemented. Each of these activities has its own distinct purpose within the design process, but none focus specifically on the thorough collection of evidence as documentation does.
