Why do field teams stop using software?
If logging a job takes longer in your app than on paper, paper wins. That's most of the problem in one sentence.
The rest is training. Rollouts usually get one session in the office, weeks before the crew needs the feature. By the time they need it, it's forgotten.
What should you fix first?
- Time the most common task on a phone, standing up. Then cut steps until it beats paper.
- Size buttons for a thumb. The W3C minimum for most controls is 24 by 24 pixels, and a gloved thumb wants far more.
- Put the task they do most on the first screen they see.
- Give help at the moment of use, inside the app, instead of in a training deck.
What does in-app help look like on a job site?
It has to work with one hand and half their attention. Reading is out. A voice that says "tap the green Complete button at the bottom" while that button lights up is about the right amount of effort.
agent247 does this in a phone's web browser. It speaks each step, highlights the button, and can tap it for them if they ask. On a loud site they can type instead.
One hard limit: it installs as a script tag on web pages, so it can't run inside a native iOS or Android app. If your field app is native, look elsewhere. A web app needs only one script tag.
How do you get the office to push it?
Give the office manager one sentence to repeat: "if you're stuck, tap the guide and ask it". That's easier to enforce than a training day.
The same ideas apply to onboarding older users and to customers who aren't tech-savvy.
