Production Excellence #33: June 2021
Monthly update on our strive for operational excellence.

How’d we do in our strive for operational excellence last month? Read on to find out!

Incidents

3 documented incidents. That's lower than June in the previous five years where the month saw 5-9 incidents. I've added a new panel ⭐️ to the Incident statistics tool. This one plots monthly statistics on top of previous years, to more easily compare them:

Learn more from the Incident documents on Wikitech, and remember to review and schedule Incident Follow-up in Phabricator, which are preventive measures and other action items filed after an incident.


Trends

In June, work on production errors appears to have stagnated a bit. Or more precisely, the work only resulted in relatively few tasks being resolved. 15 of the 26 new tasks are still open as of writing.

Of the tasks from previous months, only 11 were resolved, leaving most columns unchanged. See the table further down for a more detailed breakdown and links to Phabricator queries for the tasks in question.

With the 15 remaining new tasks, and the 11 tasks resolved from our backlog, this raises the chart from 150 to 154 tasks.

Take a look at the workboard and look for tasks that could use your help.

🕳 O'Neill: We've done this!
Dr Jackson: We do this every day.
O'Neill: I'm not talking about briefings in general, Daniel, I'm talking about this briefing; I'm talking about this day.
Teal'c: Col. O'Neill is correct. Events do appear to be repeating themselves.
