MENTAL MODEL B
THE QUESTION
Mental Model B showing Fusion as the primary environment with Supernova embedded within the platiorm.
WHAT CHANGED
A clearer and more scalable structure
The model separated the accountant’s practice environment from the wider firm platform while maintaining connections between the two. Accountants could move between firm-level capabilities, their personal practice environment and individual client books without collapsing everything into a single product context.
Fusion as the primary environment
Accountants entered through a single firm-level platform rather than a dedicated practice product.
Supernova embedded within Fusion
Practice-management capabilities became part of the broader platform experience.
A more unified product model
The approach reduced separation between firm and practice contexts, but required accountants to operate within a broader platform structure.
Simplified view of Mental Model B showing Fusion as the primary environment with Supernova embedded within the platform.
