Freeze the first-stage scope
Write down which locations, devices, order channels and reports are included. Move optional ideas into a later phase instead of changing the launch target every week.
Prepare exact data
Product names, prices, taxes, options and identifiers need a single approved source. Do not import multiple field names for the same concept.
Test complete journeys
Run dine-in, takeaway, refunds, shift change, printing, offline procedures and end-of-day work using real staff roles.
Train by role
Counter staff, supervisors and administrators need different training. Record who can change products, prices and operational settings.
Support the first live shifts
Plan who is available, how issues are recorded and which changes are safe during the first days of operation.
