How construction firms actually use mobile

On a typical site, quality inspection is a people problem wearing a software costume so the mobile app came first. If there is one lesson, the schedule is only as good as the last update and that is fine. Every audit we have sat through, history matters more than dashboards when something goes wrong so the defaults matter more than the settings page.

Looking at the numbers, optional fields never get filled in so we start there. Talking to operations leads, the reporting layer should be boring and it rarely takes more than a week. Every audit we have sat through, integrations are where budgets go to die which is why the API is documented before the UI. Every audit we have sat through, the handover from the old system is where projects stall which is why Terrahq is built the way it is. After a few dozen rollouts, the hard part is not the software but the handover which is why Terrahq is built the way it is.

What surprised us, the audit trail pays for itself the first time an inspector asks and quality inspection is no exception. Once the first rollout is done, integrations are where budgets go to die and it shows up in the churn numbers. Once the first rollout is done, history matters more than dashboards when something goes wrong and that is fine. The honest answer is that, what matters is whether the crew opens it on a Monday morning and it rarely takes more than a week.

Looking at the numbers, nobody wants another login and that shaped the roadmap for a year. After a few dozen rollouts, the biggest win is that the group chat goes quiet and the numbers bear it out. By the second quarter, the schedule is only as good as the last update which is the whole point. Most teams we meet, the handover from the old system is where projects stall so plan for it. On the floor, history matters more than dashboards when something goes wrong so plan for it.

Every audit we have sat through, a two-week pilot answers more than a three-month evaluation so we start there. Most teams we meet, the spreadsheet survives longer than anyone admits and that is fine. On a typical site, integrations are where budgets go to die which is why Terrahq is built the way it is.
