Welcome to the "other interesting work" squad.
At the start of each development iteration, a lucky few are designated as the other-interesting-work squad. These guys are in reserve to work on "unplanned" items that will enter the work-stream but while there's nothing unplanned to work on, they get to do all the fun stuff, like
new platforms or frameworks the team has been wanting to investigate
competitive coding and proof-of-concept cage-matches
katas, continuing education or certification prep
codebase care-and-feeding, implementing that shiny new CI pipeline feature
The OIW-squad trades out these tasks for unplanned work as new items enter the iteration. The unplanned intake can be the priority, but why not have a little fun along the way 😉
