The two stages require a different kind of thinking. They build on each other, together with the other stages, to come that actions that will help the team to improve effectively.
* **Gather data** is about getting information about the problem, both facts and feelings. The team will be working towards creating a shared image of the current situation based on what they know now.
* **Generate insight** is about coming to solution on how to deal with the problems that gather data has revealed. You are looking for solutions. In that process you may need to dig deeper, hence get extra information/data. You might also see this as iterating between gather data and generate insight.
Main thing to be aware is to get a good enough understanding of what the real problems are before trying to come up with solutions. This increases the chance of coming up with effective actions that will help to solve the problem or prevent it from happening in the future.
