...then you're probably already tracking Impediments properly. Or you're working 10 hour days. Or you're a machine - well done you.
If you're in the 10 hour camp, it's worth taking a step back and reading what Assaf has to say about tracking impediments. The process he puts across is simple for small Scrum teams to implement and Visual Studio Team Services (VSTS) charts and dashboards are really quick to set up and customize.
InsureTech has been using VSTS for a while now and it gives us great flexibility when managing our diverse portfolio of projects. The great thing about VSTS is how clear the charting is and how little training people need to 'get it' - even project managers understand them!
Visual Studio Team Services (or VSTS) has great tools to support Scrum teams. The product owner can use the backlog and board to track the progress of individual teams or the entire product, at the Product Backlog Item (PBI) level, at the Feature level or even the Epic level, throughout the entire lifetime of the product.
