We are going to tell a story to a user using a dashboard.
Use a single list with several web parts that have different views -Example 1 task list
Inline editing when creating a view makes a list more user friendly by allowing users to update items from the dashboard
Tabular view allows multi-selection of items
Think about using different styles when creating views. Some of the items (inline or tabular to name two) you have checked in a view cannot be shown because of the style you’ve chosen.
Just an aside: page vs new sub site. Sometimes you just need a page to display info, not a sub site. Something to think about.
What if my data lives in multiple columns?
Use lookup columns
Then use connections
