Scrum is an agile framework with very strict boundaries and plenty of freedom and flexibility within these boundaries. Scrum does have solutions to most team dysfunctions. Slipping from scrum should be a conscious decision taken by mature agile teams only!
Daily Scrum starting time (Daily Standup)
Scrum strongly suggests to never change the time and place of the Standup in order to reduce complexity. One of Standup’s main benefits is synchronization between team members. If a team member can not make it to the Standup, for any reason, its value obviously is less than optimal. We consciously choose to change the time of the Standup to ensure full attendance. This is easier to do in small teams, since in larger teams the effect of changing everyone’s schedule may outweigh the benefit of full participation.
Dangers when slipping: On a non mature agile team, delaying the Daily Standup occasionally, may be seen as if it’s not required to be on time. Also, delaying the standup may de-motivate and confuse people who are always on time.
Events Maximum Duration
All events in Scrum have a maximum duration, strictly set based on the Sprint duration. For 2 week Sprints, the suggested timeboxes are: 4 hours for Planning, 2 hours for Review, 1.5 hours for Retrospectives. We have multiple Scrum teams, that share many common stakeholders.
We consciously reduced the timebox of Sprint Reviews in 1 hour, and have all 8 Sprint Reviews from the Scrum Teams of the Department happening in the mornings of 2 consecutive days every 2 weeks. This way it is easier for many stakeholders to attend all sprint reviews.
We consciously have minimized the maximum feedback that we can take in a Sprint Review, while on the other hand we have maximized the minimum attendance!
Additionally, decreasing the average time a knowledge worker spends in meetings, improves her performance and mood!
Sprint Ends, Sprint Starts
Scrum suggests that the next Sprint starts immediately after the previous sprint ends. This way, there is no time for the team to be outside of the Sprint. This is, for me, one of the greatest things in Scrum, since it encourages the team to keep a steady pace.
There is one team, that chose to introduce some empty time between sprints in order to be able to start their Planning in the morning.
Note: when a team has the luxury to end their day with Sprint Review and Sprint Retrospective, and start their planning immediately the next morning, there is no excuse to break this rule.
