The situation

Preparation is where a day goes wrong quietly. A patient eats breakfast out of habit and the scan is postponed. The referral letter is at home in a drawer. The family drives to the main entrance, then discovers the imaging wing is closer to Gate 2. Each of these is small, and together they turn a two hour morning into five.

Most of this information exists already. It sits in an appointment letter, in a phone call from the front desk, and in the memory of whoever came last time.

What the guidance does

The preparation phase turns those fragments into a checklist with times attached. Fasting windows, contrast timing, and medication holds come from the department. Travel time comes from the map, so the departure time is calculated instead of guessed. The checklist carries the documents the department actually asks for, and the route from the parking area to the first counter.

What changes

A patient arrives with the right papers at the right time. The department cancels fewer slots. The front desk stops explaining fasting rules for the fourth time that morning.

Where this stands

Instructions and checklists are in the product plan, not in the pilot. The pieces that make it work are already running: the map provides walk times, and the journey view accepts steps with durations. What is missing is the authoring tool for departments, which is the reason this page is marked exploring.
