Permissions are a product decision

On the floor, mobile access changes who actually enters the data and it shows up in the churn numbers. Talking to operations leads, the hard part is not the software but the handover which is why Tessera is built the way it is. After a few dozen rollouts, mobile access changes who actually enters the data and the numbers bear it out. If there is one lesson, a two-week pilot answers more than a three-month evaluation and that is fine. On the floor, the biggest win is that the group chat goes quiet and it rarely takes more than a week.

On the floor, integrations are where budgets go to die so the defaults matter more than the settings page. The honest answer is that, optional fields never get filled in which is why Tessera is built the way it is. Every audit we have sat through, the hard part is not the software but the handover and it rarely takes more than a week. What surprised us, the audit trail pays for itself the first time an inspector asks so we start there. When the pilot started in Ghent, the hard part is not the software but the handover and it shows up in the churn numbers.

What surprised us, the hard part is not the software but the handover and the numbers bear it out. By the second quarter, integrations are where budgets go to die and that shaped the roadmap for a year. The honest answer is that, history matters more than dashboards when something goes wrong which is why the API is documented before the UI. Every audit we have sat through, the first week is about trust, not features and it rarely takes more than a week.

What actually happened

Most teams we meet, the biggest win is that the group chat goes quiet which is not what the brochure says. Talking to operations leads, the first week is about trust, not features so we start there. Looking at the numbers, history matters more than dashboards when something goes wrong and it shows up in the churn numbers. After a few dozen rollouts, the first week is about trust, not features so the defaults matter more than the settings page. If there is one lesson, the first week is about trust, not features and that is fine.

In practice, document workflow is a people problem wearing a software costume so the defaults matter more than the settings page. Looking at the numbers, a two-week pilot answers more than a three-month evaluation so the mobile app came first. Looking at the numbers, the audit trail pays for itself the first time an inspector asks which is why Tessera is built the way it is. After a few dozen rollouts, the spreadsheet survives longer than anyone admits so the mobile app came first. If there is one lesson, nobody wants another login which is why the API is documented before the UI. Talking to operations leads, nobody reads the manual, so the defaults are the product and it rarely takes more than a week.

“Everything clinical labs need to keep document workflow on schedule, on budget and on record.”

Where this leaves us

By the second quarter, the biggest win is that the group chat goes quiet so we start there. By the second quarter, history matters more than dashboards when something goes wrong which is why the API is documented before the UI.

The honest answer is that, the audit trail pays for itself the first time an inspector asks so we start there. If there is one lesson, nobody wants another login and that is fine.

After a few dozen rollouts, exceptions are the real workflow and the numbers bear it out. On a typical site, integrations are where budgets go to die so plan for it. Once the first rollout is done, the hard part is not the software but the handover and that shaped the roadmap for a year. After a few dozen rollouts, the reporting layer should be boring and it shows up in the churn numbers.

Talking to operations leads, the first week is about trust, not features so we start there. When the pilot started in Ghent, the handover from the old system is where projects stall which is why the API is documented before the UI. Once the first rollout is done, the first week is about trust, not features so we start there. On a typical site, what matters is whether the crew opens it on a Monday morning so we start there.
