Client challenge

The chain had expanded quickly, and complaints about slow service, cold food and incorrect delivery orders were rising. Head office had operating standards but no independent measure of whether outlets met them.

Research methodology

A structured quantitative design, so results could be compared across groups, locations and time.

  1. 1Brief
  2. 2Mystery dining visits
  3. 3Delivery order audits
  4. 4Outlet scorecards
  5. 5Insight

Trained mystery diners visited outlets at lunch, dinner and late-night periods, scoring greeting, order accuracy, waiting time, food temperature, cleanliness and staff behaviour. Separate delivery orders through apps measured accuracy, packaging and arrival temperature. Each visit was photo-documented, and results were shared as outlet scorecards with regional managers.

Brief & design Sampling & set-up Fieldwork Analysis Reporting Indicative phasing.

Data quality & validation

  • Back-checks on a share of completed interviews
  • Time and location checks on field interviews
  • Supervisor accompaniment in the field
  • Photo or document evidence for audit points
  • Second-reviewer checks on scores
  • Logic and range checks on the final data
  • Work carried out under our ISO 20252 quality procedures
11

Data analysis

  • Cross-tabulation by key groups and locations
  • Significance testing on the differences that mattered
  • Interactive dashboard for ongoing tracking
12

Key findings

  • Late-night service and delivery order accuracy were the weakest areas.
Measuring delivery separately revealed problems dine-in visits would have missed.
13

Recommendations

  • The chain revised staffing for late shifts, added an order-check step before delivery handover and linked part of outlet bonuses to scorecard results.
  • Share the findings with the teams closest to customers so they can act quickly.
