What we demonstrate
Each environment below is running software, not a slide deck. The screenshots are taken straight out of the running system.
Every one of them runs on a fictional composite estate with generated data. That is a deliberate constraint rather than a limitation: it means a demonstration can be shown to anybody, and that what you are looking at is the method rather than somebody else's numbers.
How a briefing works
A demonstration is normally a screen share, because it lets us stop on whatever you want to interrogate. Where it is useful for you to explore the environment yourself, access is issued to named people for a scheduled window.
Either way there is a written pack with the screenshots, the reasoning and the honest limitations, so there is something to circulate afterwards to people who were not in the room.
