What 100,000 Leaders Taught Us About Cross-Functional Decision Making

Ask a senior leader where their strategy broke down and you rarely hear that they picked the wrong plan. You hear that the plan was sound and the organization could not act on it as one.

Our new ebook, The Cross-Functional Playbook: 5 Skills Leaders Need to Get Things Done Across Functions, explores why this keeps happening, drawing on what we’ve seen across the 100,000+ leaders who have come through our programs. Three themes from the report:

Authority Is No Longer the Operating System

Flatter organizations mean fewer decisions come with authority attached, and matrixed reporting means the people you need most are the people you cannot direct. AI is raising the stakes further by arming every function with its own analysis and its own version of the truth.

Individual speed, however, is not organizational speed. AI can make every person faster and still leave the company slower, because the friction moves to the seams between functions: the buy-in, the approvals, and the shared understanding that keeps everyone working from the same page.

The Gap Is Rarely the Decision Itself

Most cross-functional decisions do not fail because the choice was wrong. They fail because the process was accidental, or because the decision never got shared in a way that made anyone accountable for moving it. In our 2026 Leadership Development Effectiveness Survey, 38% of L&D leaders pointed to low participation or competing priorities and 31% to weak manager follow-through as the reasons initiatives break down after launch. Both are communication failures in disguise.

The playbook breaks the work into five skills that track the life of a single decision, from how a leader frames the tradeoff to how the decision gets handed off. The report spans the spectrum from enterprise thinking to cross-functional communication, exploring what strong leaders actually do at each stage.

These Skills Are Built, Not Briefed

None of the five is learned from content alone. They are built the way any real skill is built, by practicing the actual moment under realistic pressure, with feedback, and then doing it agaiIn most word processing programs, like Microsoft Word or Google Docs, you can adjust text size easily. Just highlight the word and change the font size to Heading 3 (which is usually around 16-18 pt). Click on the font size dropdown menu, choose your size, and voilà!n. The playbook walks through what that looks like for each skill, including the specific practices strong leaders rely on, the results behind them, and how the five map to development from rising leaders through senior teams.
