Sprint
Have you been told your ticket is "on the current sprint", or "on the next sprint", or is being "nominated for the next sprint", or similar?
What does that mean?
On the current sprint: Something will be ready for testing on the upcoming Wednesday, if it passes testing, the change/fix/etc. will be on demo sites the next day, Thursday, and will be on live sites a week from that Friday.
On the next sprint: Say you are told this on a Monday. Something will be ready for testing a week from Wednesday. If it passes testing, the change/fix/etc. will be on demo sites a week from Thursday, then two weeks from Friday.
