I am yet to work on a project where environmental issues haven’t impacted my schedule to some degree. But it seems that I only start to document the outages once they start to seriously impact my schedule.
This stops now.
From now on I will document every outage (no matter how trivial) before they start to have any impact. Once the cumulative downtime reaches more than a few hours, I will include a link to the outage document as part of my weekly (or daily) status report.
Here is a template for my Environment Availability Spreadsheet.
