As an Enterprise Agile coach, I teach companies the six rules for reducing cycle time.
Limit work to capacity
Even out arrival of work
Minimize the number of Things-In-Process
Minimize the size of Things-In-Process (small user stories)
Use pull scheduling
Establish a regular cadence
What’s regular cadence? Well... if you have ten Scrum teams working on software, each team should be working on Sprints of the same length. Let's say your sprints are two weeks long.
The sprints should start and end on the same day each sprint. This way executives, developers and support know when the sprint review will be and when sprint planning happens. Teams know how to sync user stories and eliminate dependencies.
Product owners know how to schedule and release software that delights customers.
