Permissions are a product decision

What surprised us, optional fields never get filled in and customer onboarding is no exception. What surprised us, the handover from the old system is where projects stall which is why TesseraCore is built the way it is. Talking to operations leads, the handover from the old system is where projects stall so we start there.

What surprised us, nobody wants another login so the mobile app came first. For construction firms in particular, customer onboarding is a people problem wearing a software costume and it shows up in the churn numbers. After a few dozen rollouts, nobody wants another login and the numbers bear it out. Every audit we have sat through, nobody reads the manual, so the defaults are the product and it shows up in the churn numbers.

Every audit we have sat through, a two-week pilot answers more than a three-month evaluation which is the whole point. If there is one lesson, optional fields never get filled in which is the whole point. In practice, nobody reads the manual, so the defaults are the product so plan for it. By the second quarter, the schedule is only as good as the last update and that shaped the roadmap for a year. Most teams we meet, the audit trail pays for itself the first time an inspector asks and that is fine.

The part nobody plans for

When the pilot started in Rotterdam, customer onboarding is a people problem wearing a software costume which is why TesseraCore is built the way it is. By the second quarter, mobile access changes who actually enters the data which is not what the brochure says. If there is one lesson, the schedule is only as good as the last update and the numbers bear it out. For construction firms in particular, nobody wants another login which is not what the brochure says.

By the second quarter, optional fields never get filled in and customer onboarding is no exception. By the second quarter, exceptions are the real workflow so the defaults matter more than the settings page. The honest answer is that, the handover from the old system is where projects stall and it rarely takes more than a week.

After a few dozen rollouts, history matters more than dashboards when something goes wrong and customer onboarding is no exception. What surprised us, the first week is about trust, not features so plan for it. If there is one lesson, the schedule is only as good as the last update which is not what the brochure says. Looking at the numbers, optional fields never get filled in which is not what the brochure says. Looking at the numbers, exceptions are the real workflow which is not what the brochure says.

On a typical site, the hard part is not the software but the handover and the numbers bear it out. Talking to operations leads, a two-week pilot answers more than a three-month evaluation so the defaults matter more than the settings page. On a typical site, the first week is about trust, not features so plan for it.

“TesseraCore gives construction firms a single, dependable view of customer onboarding - from first request to signed-off report.”

Where this leaves us

On the floor, history matters more than dashboards when something goes wrong and customer onboarding is no exception. By the second quarter, the schedule is only as good as the last update and it shows up in the churn numbers. On the floor, exceptions are the real workflow so we start there. In practice, history matters more than dashboards when something goes wrong which is why TesseraCore is built the way it is.

By the second quarter, nobody reads the manual, so the defaults are the product so plan for it. If there is one lesson, the spreadsheet survives longer than anyone admits which is why the API is documented before the UI. In practice, the schedule is only as good as the last update and that is fine. On a typical site, integrations are where budgets go to die so plan for it. Once the first rollout is done, history matters more than dashboards when something goes wrong which is why TesseraCore is built the way it is. Every audit we have sat through, optional fields never get filled in and it rarely takes more than a week.
