Final answer:
The research stage of creative performance is when information about the problem is gathered, involving stakeholder insights, expert consultation, and root cause analysis.
Step-by-step explanation:
Gathering information about the problem occurs in the research stage of creative performance. This stage involves activities such as gathering information from customers and other stakeholders, finding expert information through various sources, and conducting a root cause analysis to identify the underlying issues that need to be addressed. Once the research is complete, the selection of details and ideas takes place, leading to the implementation phase where the creative project truly starts to take shape. In the context of theater production, for example, this is when initial designs are turned into concrete sets, props, and costumes.
