IAS/
MENTAL MODEL A
THE QUESTION
Mental Model A showing the relationship between the practice experience, firm structure and SMB platforms.
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.
Practice-led experience
IAS remained the accountant’s primary environment for managing practice and client work.
Firm capabilities through Fusion
Broader operational capabilities sat within Fusion and connected back into the practice experience.
Client books remained distinct
Accountants could move into individual client environments without losing the separation between practice-level and client-level work.
Simplified view of Mental Model A showing the relationship between the firm, the accountant’s practice and individual client books.
