Problem Statement Description
You are evaluating the annual business opportunity for a mobile calendar assistant designed for restaurant owners. The assistant could help owners manage reservations, supplier meetings, staff schedules, catering inquiries, private-event bookings, customer follow-ups, and reminders from a phone-first workflow.
Frame the opportunity as a guesstimate: define the relevant market, estimate how many restaurant owners or decision-makers could realistically use such a tool in a year, and translate that into a business opportunity. You should also connect the market estimate to lead conversion, such as how many prospects could become qualified leads, trials, paying customers, or booked sales conversations.
Your estimate should be grounded in clear assumptions rather than exact external data. Make the scope explicit, show the calculation structure, and identify which assumptions most influence the final opportunity size.
The experience should consider:
- The geographic scope and time period of the estimate, with “annual opportunity” clearly defined
- The unit of analysis, such as restaurant locations, owners, operators, or decision-makers
- Relevant restaurant segments, including independent restaurants, small chains, cafés, bars, and multi-location operators
- Mobile readiness and calendar-assistant fit based on owner workflow frequency and pain intensity
- Adoption assumptions, including awareness, willingness to try, and likelihood of recurring use
- Lead-conversion funnel stages, from reachable prospects to qualified leads and customers
- Sensitivity of the estimate to major assumptions such as market size, conversion rate, pricing, and retention
- Sanity checks to ensure the final number is directionally credible
Your goal is to produce a structured, defensible estimate of the annual opportunity and explain how that opportunity could translate into a lead-generation or sales funnel for a mobile calendar assistant serving restaurant owners.
