For a while now, teams have been categorizing their quarterly goals into Strengthen/Focus/Experiment. Will Core/Strategic replace that categorization, or will both be used?
Topic on Talk:Team Practices Group/Tracking core and strategic work
Personal opinion: I think the use of Strengthen/Focus/Experiment has been quite arbitrary. These axes were supposed to have a connection with the Call to Action, which was another new artifact established with no prior discussion. Even if still fuzzy, the Core/Strategic distinction is clearer and here we are discussing it openly. The WMF Annual Plan is being structured around these concepts. This looks indeed like a more solid foundation. I don't see the need to keep both classifications around. Good bye Strengthen/Focus/Experiment?
"Experiments" are presumably mostly "Strategic", and "Strengthen" is presumably – usually – "Core". "Focus" could be either. If both systems are used, then you'd have another 3x2 matrix.
@WMoran (WMF): Can you confirm that teams can stop tracking Strengthen/Focus/Experiment, if they are instead tracking Core/Strategic?
