For Market Research Analysis

I need to conduct a market research analysis for my business, which is a {type of business, e.g., a specialty coffee subscription service based in the UK}. The primary and most urgent question I need to answer with this research is: {state the specific research question, e.g., 'Is there a viable market for a premium, ethically-sourced coffee subscription among remote workers in major UK cities?'}. To begin, please act as a market research analyst and outline the three most important categories of information I need to find to answer this question, briefly explaining why each is critical for the analysis.
