Can the tasks of the Sprint Backlog be removed?

I was asked this question in a thread at LinkedIn

The answer: “Yes, …IF…¨

• 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
