How to choose an executive assessment firm
How to compare executive assessment firms on the axes that actually predict useful evaluation: method depth, stance discipline, mandate literacy, appraiser calibration, defensibility.
Insights
Books, canonical references, practical guides, articles, and field notes for leaders working through succession, governance, organization design, and capability. Each begins with the work itself — helping complex questions become clearer, more defensible, and more useful in action.

Mastering Competencies Across Levels of Work.
Now in its second edition, this is a working guide for leaders who need sharper judgment rather than another set of slogans. Jose J. Ruiz treats leadership as work that runs a continuous cycle — Design, Organize, Execute, Sustain — the DOES model that shows how strong organizations turn complexity into coherent choice, coordinated action, disciplined delivery, and long-term renewal. This edition adds a tighter architecture: the Triad of Direction, which keeps Management, Leadership, and Stewardship distinct instead of blurring them into one vague notion, and Levels of Work as the lens on every competency — the same discipline that looks procedural in one role becomes coordinating in another, architectural in another, and organization-shaping at the highest levels as time horizon, complexity, and consequence expand.

Building an Organization Complexity Can't Break.
In The Capability Advantage, Jose J. Ruiz shows why growth turns brittle when organizations confuse three different things: Ability (skill you can execute now), Capability (judgment that holds complexity across time), and Capacity (the scope and scale at which Ability and Capability can be applied without losing coherence). When those distinctions collapse, leaders reach for the wrong lever — training, pressure, headcount, more approvals — and the organization pays in rework, bottlenecks, and quiet exhaustion. The book reframes Organizational Capability as system-level coherence: how decision rights, structures, and culture turn diverse perspectives into a shared sense over time. You'll learn to read Flow Collapse not as a motivation problem, but as the system telling the truth — early evidence of misfit in scope, borders, time horizon, or cultural pressure.
Long-form
Developed arguments about leadership, capability, organizations, and consequential decisions — written to examine a question in depth and arrive at a defensible point of view.

How the board reads DG succession readiness in Mexican companies: the mandate the seat will hold, the judgment the candidate carries, and the calendar that makes the reading defensible.
A board effectiveness assessment reads the board as a governance instrument, not a satisfaction survey. What it measures, what it doesn't, when to run it, and how it becomes a decision.
From the practice
Anonymized executive learning briefs from real engagements — how the work was defined, what the appreciation surfaced, and what the client now operates deliberately.
A board evaluation at a family-controlled industrial manufacturer revealed a high-performing board supervising a plan whose assumptions the world had already moved past — and traced the gap to a mandate that had never been put on the table.
More than twenty HR executives and managers across five countries trained to deploy the Levels of Work methodology inside the group's own talent system — work described before the person is judged, and talent reviews that run on a common language across every business.
Core criteria for family board members designed before any evaluation, individual assessments of third-generation members across capability, ability, and capacity, and seat assignment on evidence — with ongoing evaluations and personal development plans that turn a succession dispute into a development system.
Field notes
Short observations from live work: a distinction worth making, a pattern worth noticing, or a question that changes how a decision is framed.
Jobs-to-be-done → key questions → evidence-based answers → storyline. The throughline that turns insight into decision.
Leaders over-control, over-escalate or improvise when the moment turns. Decision quality degrades exactly when it is needed most.
Most competency models are a category error. Here is what the underlying architecture actually looks like.
