Checklists on WhatsApp: when they work, and when to use the app

Housekeeping staff, security guards, kitchen helpers and contract workers often share phones, have little storage, or simply won't install another app for their employer. Their sites end up on paper, or on photos posted to a group chat that nobody checks.

WhatsApp is already installed and already used every day. A checklist that arrives there, at the time it's due, removes the install from the problem.

A group is a stream of messages. Photos arrive in any order, with no question attached, and finding last Tuesday's opening check means scrolling.

A WhatsApp checklist is a structured form inside the chat: the person on duty gets a message, taps Start, answers each question (a photo, a reading, yes or no) and sends it. The answers are filed against the site and the check, like any other, so head office sees them in the same place as the app's.

Works well:

• Photos of the thing being checked.
• Readings, such as a temperature.
• Yes or no, and simple choices.

Better in the app:

• Signatures, voice notes, video and location.
• Checks where a failing photo must be retaken before the person leaves. On WhatsApp, the photo is checked when it arrives, so a failure is flagged for a manager to review instead.
• Work in places without signal, where the app saves answers offline.

Send each message a set time before the check is due, only to people who can actually fill it, and skip sites that have already filed. A message that arrives when the work is due, and only then, gets answered; one that arrives every hour gets muted.

With the WhatsApp checklists add-on, ZealMint Operations AI sends a checklist on its schedule, before it's due, to the person on duty. They fill it in without leaving the chat, the answers are filed like any other, and photos are checked by AI when they arrive. A checklist with a required signature, voice note, video or location stays in the app.
