How’d we do in our strive for operational excellence last month? Read on to find out!
📊 Month in numbers
- 11 documented incidents. ⚠️ [1]
- 39 new Wikimedia-prod-error reports. [2]
- 25 Wikimedia-prod-error reports closed. [3]
The number of incidents in June was high compared to previous years. At 11 incidents, this is higher than this year’s median (5), the 2018 median (4), and the 2017 median (5). It is also higher than any month of June in the last 4 years. – More data at CodePen.
To read more about these incidents, their investigations, and pending actionables; check Incident documentation § 2019.
There are currently 204 open Wikimedia-prod-error reports (up from 186 in April, and 201 in May). [4]
📖 [Op-ed] Integrated maintenance cost
Hereby a shoutout to the Wikidata and Core Platform teams, at WMDE and WMF respectively. They both recently established a rotating subteam that focuses on incidental work. Such as maintenance, and other work that might otherwise hinder feature development.
I expect this to improve efficiency by avoiding context switches between feature and incidental work. The rotational aspect should distribute the work more evenly among team members (avoiding burnout). And, it may increase exposure to other teams, and lesser-known areas of our code; which provide opportunities for personal growth and to retain institutional knowledge.
