Worth including
The environment — version, online or on-premises, roughly how old. The symptom, in whatever words you would use to a colleague. Any deadline that is real.
What happens
A reply that either says this is a job for us and what the next step is, or says it is not and — where we can — what to look at instead.
Not needed yet
An RFP, a scope document, or a budget number. Those come after we both know what the work is.
