A visual approach for scoping the most important features of a product/service. It is a drawing of multiple concentric circles, each of which represents an additional layer of details for the product/service. At the core are the generic product/service characteristics (features), followed by minimal conditions circle (must haves), an augmented product circle, a potential circle (differentiations and customer retention features) and additional circles if required.

• Opens up the product development for the whole team
• Identifies what matters and get everyone on the team to understand the design and prioritisation of features
• Provides transparency in prioritisation and strategy/vision alignment
• Helps move the focus on the important / differentiating features
• When used for existing products/services allows for uncovering options for pivoting

• This practice could be used in combination with practices as Impact Mapping, Lean Canvas, Value Proposition in order to build a vision for a product/service and translate that vision into actionable and prioritized set of features.
• The output from the practice may invoke User Research, Usability Reviews (for existing products/services)
• It can also serve as prioritisation tool for the Product Backlog
