Restaurants
Plan purchasing with a clearer view of demand.
A 16-person restaurant plans purchasing from till data, bookings and staff experience. Daily consolidation is manual.
These cases show how we would apply our method to different professional situations. Business profiles, countries, timelines and gains are illustrative assumptions. They do not describe completed client engagements.
Illustrative audit · 4 pages · no registration
- Simulated schedule
- 6 weeks
- Support planned in the scenario
- 7 consulting days
- Simulated net time saving
- 6.7 h / month
Assumed internal commitment : 3 person-days. Consulting days are spread across the schedule and do not mean full-time attendance. Internal days are additional. Scope and a quote must be agreed for a real engagement.
01 / Proposed audit scope
Restaurant
Daily purchasing preparation and variance tracking, without automatic supplier orders.
What we would examine
Scenario dataset covering 12 weeks: sales, bookings, purchases and waste, with closures and events identified.
02 / The process, department by department
| Department | Simulated starting point | Proposed process | Human approval |
|---|---|---|---|
| Purchasing & inventory | Rebuild the list each morning | Purchasing suggestion from sales and bookings | Head chef |
| Operations & production | Observe variances without a shared history | Track waste and shortages by service | Operations manager |
| Human resources | Method dependent on one person | Documented routine and training for a backup | Manager |
The approach to compare
Compare a simple weekday forecast with a lightweight predictive model. Explain differences and propose an editable purchasing list.
What stays with the professional
The chef approves quantities and orders. Allergens, temperatures and hygiene remain governed by existing professional procedures.
03 / From audit to an independent team
6 weeks.
7 consulting days.
A simulated engagement timeline, with a decision and deliverable at every stage. Rollout depends on test results.
Week 1 · 1.5 consulting days
Observe & measure
Scenario dataset covering 12 weeks: sales, bookings, purchases and waste, with closures and events identified.
Proposed deliverable Process map, baseline measurement and issue register.
Week 2 · 1 consulting days
Scope & decide
Compare simplification, existing features and AI. Define scope, access, full costs and stop criteria before building.
Proposed deliverable Audit report, priority matrix and test protocol.
Week 3 · 2 consulting days
Prototype
Compare a simple weekday forecast with a lightweight predictive model. Explain differences and propose an editable purchasing list.
Proposed deliverable Limited prototype, test set and approval workflow.
Weeks 4–5 · 1.5 consulting days
Test & decide
Compare on weeks not used to prepare the model; track waste, shortages and correction time together.
Proposed deliverable Comparative assessment: proceed, adjust or stop.
Week 6 · 1 consulting days
Train & hand over
Train users on routine and exceptional cases. Appoint an owner and document the manual fallback. If testing fails, hand over findings and a correction plan.
Proposed deliverable Usage guide, team workshop and 30-day follow-up plan.
04 / What the scenario aims to achieve
Simulated net time saving
6.7 h / monthSpend less time consolidating figures before service. Any waste reduction must be demonstrated separately.
- Assumed monthly volume
- 26 daily planning sessions
- Baseline time per unit
- 45 min
- Target time, including human review
- 25 min
- Monthly monitoring and maintenance
- 2 h
Transparent calculation
26 × (45 − 25) ÷ 60 − 2 = 6.7 h / month
Volume × (baseline time − target time) ÷ 60 − monthly monitoring.
If only half the volume benefits from the process, with the same monthly monitoring: 2.3 h / month
This calculation is a simulation, not a client measurement. Target time includes corrections and review. Time released is not a demonstrated cash saving; it depends on actual volume and adoption.
Costs to compare with the benefit
Cost advice, data preparation, integration, licences, training and maintenance before committing. Price, return on investment and revenue effects must be established for each engagement.
How we would verify the result
Compare both methods on a set separate from preparation examples. Measure total time, corrections, critical errors and actual use. Keep difficult cases in the assessment; suspend if quality or confidentiality deteriorates.
Professional acceptance criterion : Compare on weeks not used to prepare the model; track waste, shortages and correction time together.
After the pilot
During the 30 days after an approved pilot: review metrics weekly, examine exceptions and decide whether to maintain, correct or expand the scope. This follow-up period is outside the scenario schedule and consulting days.
Before a pilot, define permitted data, access and any supplier reuse. Country-specific and professional rules must be checked for the real engagement.
