The Role Layer Book
The Missing Intelligence in Enterprise AI Adoption
Simon MacTaggart
Publishing 2026
Every enterprise is adopting AI. But the intelligence most leaders rely on to guide that adoption (vendor benchmarks, industry surveys, analyst reports) measures the wrong thing at the wrong level.
What’s missing is not more data about AI. It’s data about the people making the decisions. How aligned are the ten executive roles responsible for committing capital, managing risk, and scaling implementation? Where do they agree? Where do they diverge? And how long will it take them to converge?
The Role Layer reveals what happens when you measure AI adoption at the level where decisions actually form. Not the enterprise. Not the sector. The individual executive role.
Drawing on original quarterly fieldwork across ten C-suite positions (CEO, CTO/CIO, COO, CFO, CMO, CRO, CDO, CISO, CHRO, and CLO), the book shows that AI adoption is not a technology problem. It is a coordination problem between roles that see the same technology from fundamentally different positions, carry different risk tolerances, require different evidence, and operate on different timelines.
The result is a pattern that repeats across every organisation and every sector: misalignment that is invisible from the top, unmeasurable by existing tools, and expensive when it compounds into premature commitment or prolonged indecision.
The book introduces six proprietary instruments developed through Quaie’s longitudinal research programme:
Role Shift Index. Tracking where each executive role sits on the adoption spectrum, and whether that position holds, advances, or reverts across quarters.
Role Lead-Lag Ranking. Mapping the temporal distance between roles as they move through adoption, showing which functions lead, which follow, and whether the gap is closing.
Organisational Adoption Gradient. Measuring the distance between the most advanced and least advanced roles within the same enterprise, quantifying the misalignment that enterprise-level averages conceal.
Consensus Formation Time. Estimating how many quarters it will take for an organisation’s leadership to reach sufficient convergence for committed action.
Role Alignment Map. Charting the degree to which leadership roles share a common interpretation of AI strategy, ownership, and organisational direction.
Role Influence Index. Identifying which leadership roles most strongly shape adoption decisions, revealing the catalysts, validators, and gatekeepers within the enterprise decision system.
The Role Layer argues that enterprise AI adoption operates on generational timescales, and that the organisations most likely to succeed are not those that move fastest, but those that build the internal alignment to move together.
Case studies include Zillow’s $421 million iBuying loss, IBM Watson Health’s $4 billion misallocation, Goldman Sachs’ deliberate sequencing under CIO Marco Argenti, and the historical precedents of ERP adoption failures at Hershey’s and FoxMeyer. Every claim is sourced from SEC filings, earnings calls, regulatory investigations, and published primary research.
The Role Layer is the foundation of Quaie’s research programme and The Role Layer Intelligence Quarterly, which tracks these dynamics across enterprises every quarter.
About the Author
Simon MacTaggart is the Founding Editor of Quaie and the creator of the Role Layer Intelligence System. He has worked across strategy, brand, and creative execution for Nike, Honda, and other global organisations, and has spent an unhealthy proportion of his career fascinated by a single question: why do some organisations successfully adopt new ideas and technologies, while others, with the same resources and intent, struggle? The answer, he concluded, is not capability. It is the gap between leadership roles, the distance between the function that has reached conviction and the function that has not yet seen the evidence that makes commitment rational. That gap is the Role Layer. This book is the argument for why it matters, and why measuring it changes what organisations can do about it. The Role Layer is his first book.
