We don't keep a site diary at all
Everyone means to. Nobody does. And the questions that need it arrive months later.
What's happening?
The site diary dies of good intentions: it is nobody's job, the day it would record is busy, and the value only shows up months later, when someone asks what was happening on site the week the account says everything went wrong. By then the diary that wasn't kept has become the evidence that doesn't exist.
What makes a diary useful is not eloquence but habit: the same fields every day - labour, plant, weather, areas worked, visitors, what stopped and why - five minutes at the same time, kept by someone named. Contemporaneous, routine records carry weight out of all proportion to the effort, precisely because they were written before anyone had a position to defend.
The template is the habit in fillable form; the capture service is the next step where the habit needs building across a site team rather than a person.
The solution
Five named minutes a day, kept before positions exist.
If you would rather it were done for you, Site Records & Progress Capture is the service that does it.
