I would like to talk about issues the teams find with Scrum and how we can address them by introducing Kanban practices and philosophy
1. People working separately in platforms
2. Unmeaningful dailies
3. Horizontal burndown charts
4. Half of the user stories in progress on the first day of the sprint
5. Dragging user stories from one sprint to another

How to help mitigate those issues and increase collaboration and teamwork?

One of the options is by introducing elements of Kanban Method into Scrum. I´m far from thinking that there is a silver bullet to any problems. Each team is unique and has their own way of collaboration. But there are some practices and tools that can help at list mitigate some of the problems the teams might face with Scrum.

Some ideas from Kanban on how to deal with the problems identified above:
1. Thanks to WIP, swarming, cross-team testing
2. Walk the board
3. Dailies help focus on what to finish each day “stop starting, start finishing”
4. WIP
5. Focus on metrics and continuous improvement
