Can the Tasks of the Sprint Backlog Be Modified Mid-Sprint?

I was asked this question in a thread at LinkedIn: Can the Tasks of the Sprint Backlog Be Modified Mid-Sprint?

The answer: "Yes, …IF…"

That's a big IF — Let's explore that.

00:20 Yes, tasks can be modified throughout the Sprint. IF...
00:45 Scenario 1
01:20 Sprint Planning
01:45 Decompose the Sprint Goal into Tasks
02:24 Mid-Sprint Adaptation of the Sprint Backlog
03:11 Discontinuous Improvement
03:38 Scenario 2: An Analogy
03:46 Product Vision
04:40 Product Goal
05:30 Sprint Goal
06:06 Product Backlog Items Selection
06:46 Sprint Backlog Tasks
07:12 The Original Question: Return
07:56 Developers change/update the tasks
08:20 Sprint Goal and PBI selection has not changed
08:49 Common pitfall! (Don't change the Sprint Goal)
09:30 Conclusion 1: Product Backlog is different than Sprint Backlog
10:23 Conclusion 2: Developers own the Sprint Backlog
10:52 Outro
