Recently purchased jira software and learn basics from the internet. Now I'm bit confused with meeting lifecycle. Here is the list of meetings and process that I sorted out as my knowledge.
Product backlog - Created by product owner.
Backlog grooming - Before starting the sprint | product owner/scrum master/dev team | 30minutes
Sprint planning - 2 week sprint | product owner/scrum master/dev team | duration = 2hour
Sprint review - End of sprint | product owner/scrum master/dev team | duration = 2hour
Sprint retro - product owner(Optional)/scrum master/dev team | duration = 90 minutes
Am I missing something here or doing wrong?
