How’d we do in our strive for operational excellence last month? Read on to find out!
Read on Phabricator at https://phabricator.wikimedia.org/phame/post/view/228 📈 Incidents 3 documented incidents last month, [1] which is average for the time of year. [2] Learn about these incidents at Incident status <https://wikitech.wikimedia.org/wiki/Incident_status> on Wikitech, and their Preventive measures <https://phabricator.wikimedia.org/project/view/4758/> in Phabricator. For those with NDA-restricted access, there may be additional private incident reports <https://drive.google.com/drive/u/0/folders/1d2hlER4s_GPe0TWDqNfa2RQcYFuOdhOo> available. 💡 *Did you know: Our Incident reports have switched to using the ISO date format in their titles and listings, for improved readability and edit-ability (esp. when publishing on a later date). So long 202010221, and hello 2021-02-21!* ------- 📊 Trends In February we saw a continuation of the new downward trend that began this January <https://phabricator.wikimedia.org/phame/post/view/227/production_excellence_28_january_2021/>, which came after twelve months of continued rising. Let's make sure this trend sticks with us as we work our way through the debt, whilst also learning to have a healthy week-to-week iteration where we monitor and follow-up on any new developments such that they don't introduce lasting regressions. The recent tally (issues filed since we started reporting in March 2019) is down to 138 unresolved errors, from 152 last month. The old backlog (pre-2019 issues) also continued its 5-month streak and is down to 148, from 160 last month. If this progress continues we'll soon have fewer "Old" issues than "Recent" issues, and possibly by the start of 2022 we may be able to report and focus only on our rotation through recent issues as hopefully we are then balancing our work such that issues reported this month are addressed mostly in the same month or otherwise later that quarter within 2-3 months. Visually that would manifest as the colored chunks having a short life on the chart with each drawn at a sharp downwards angle – instead of dragged out where it was building up an ever-taller shortcake. I do like cake, but I prefer the kind I can eat. 🍰 Month-over-month plots based on spreadsheet data <https://docs.google.com/spreadsheets/d/e/2PACX-1vTrUCAI10hIroYDU-i5_8s7pony8M71ATXrFRiXXV7t5-tITZYrTRLGch-3iJbmeG41ZMcj1vGfzZ70/pubhtml>.
