Days 1–7 — pick a single site as the reference
Do not roll out to all sites at once. Pick one high-performing site with a proactive manager and run the whole transition there first. You'll discover which check frequencies actually work at 6am with wet gloves on, which fridge sensors need re-calibrating before they can be trusted, and which supplier deliveries land at exactly the wrong time for the receiving check. Fix all of that at one site before you scale.
Days 8–14 — codify the check list
Every check has three attributes: frequency (per shift, per delivery, per day), evidence type (temperature, photo, checkbox, free text) and escalation (who gets notified on a fail, and within what window). Write these down for every existing paper check before moving anything. Half your existing paper checks won't survive the exercise — they duplicate each other, they're not required by your HACCP plan, or they're required by an old plan that hasn't been revised in five years.
Days 15–21 — pilot with the morning team only
Roll the digital system out to the opening shift first. They set the tone for the day, they do the heaviest check load, and they're the team who most benefit from not carrying a wet clipboard. Get their sign-off on the flow before rolling to evening and weekend shifts. If the morning team hates the flow, the evening team will refuse to touch it.
Days 22–30 — full site cutover, paper as backup for one week only
Full cutover on day 22 with paper kept as backup for exactly one week. On day 30, paper is retired at that site. Don't extend the backup period — every day of overlap is a day the team runs both systems and neither is trusted. The one-week backup is the safety net; the deadline is the forcing function.
The multi-site roll-out cadence
After the reference site, roll out one new site per week for the first month, then two per week. A regional manager should shadow each site's opening morning after cutover — not to check on compliance, but to spot friction the system can't see. Multi-site roll-outs that skip this step lose 20% of the compliance benefit within the first quarter.
The 30-day transition works because it makes the reference site the source of truth, not the software vendor's demo. Ekspedite is designed around this cadence — one site at a time, with the check list you already have.
