The "Bob" Problem 👀

I was coaching a Design Director this week—let’s call him Bob. He’s brilliant, his team is elite, and their work is impeccable. Yet, he was feeling a very modern kind of anxiety.

In the current "economic efficiency" climate, Bob felt his department's value was being sidelined. He told me:

"I feel like there’s a silent code in the office: Product and Engineering own the 'Why' and the 'What,' and my team is just here to make the AI look good."

If you feel like your department is the first on the chopping block, it’s usually a translation error. You are speaking the language of "User Delight," while the CFO is speaking the language of "Business Impact."

📐 The Angle: The Business of Design

Coming from my time at Apple and Meta, I saw that the most successful leaders don't try to prove that a specific hex code increased the stock price. That’s a losing battle. Instead, they use Behavioral Proxies. A behavioral proxy is a "clue"—a specific, countable action that tells you something big is about to happen before it shows up in the bank account.

☕ The Coffee Shop Analogy:

Imagine you own a coffee shop. You want to know if people love your brand.

  • The Fluff: A customer says, "I love this place!" (Nice, but unquantifiable).

  • The Proxy: The customer brought a friend. If you see more people bringing friends, you can be 90% sure your sales will be up next month.

Lagging vs. Leading: The Boardroom Gap

Most businesses track Lagging Indicators (total profit, yearly revenue). The problem? By the time you see those numbers, you can’t change them.

Smart leaders track Leading Indicators (Behavioral Proxies)—actions customers take right now that predict future money.

The High-Level Goal

The Behavioral Proxy (The "Leading" Clue)

The Logic

High Subscription Renewals

Did the customer log in 4+ times this week?

If they aren't using it (behavior), they won't pay for it next year (outcome).

Lower Support Costs

Did the user find the "Self-Help" toggle in < 3 clicks?

If they solve it themselves, you just saved £50 on a support call.

🏆 How Bob Used This to Win

Bob realized he couldn't just say a "cleaner layout" made the company £1 million. He had to connect Pixels to NRR (Net Revenue Retention). To make his case, Bob’s chosen behavior (Feature Adoption Depth) had to meet three criteria:

  1. Observable: He can see in the data exactly who is clicking the AI tools.

  2. Correlated: Users who try 3+ features almost never cancel. There is a direct link between "usage" and "staying."

  3. Influencable: Bob’s team can’t force a customer to pay, but they can make those features easier to find and faster to use. Design owns the influence.

The Transformation: "Fixer" vs. "Strategic Leader"

The Old Way (The "Fixer" Voice):

"We’re redesigning the dashboard to make it look modern and reduce friction."

  • What the Board hears: "We’re spending money on decorations."

🆕 The New Way (The "Leader" Voice):

"Our data shows users who adopt three AI features are 60% less likely to churn. We are redesigning the interface specifically to increase Feature Adoption Depth to protect our NRR."

  • What the Board hears: "Bob is a genius who is securing our revenue."

🚀 The Short of It

Executive sponsorship isn’t a gift; it’s the ROI of proving you understand the business. The moment you stop being the person who "fixes the colors" and become the one who "de-risks the roadmap," everything changes. When you own the behavior, you own the "Why."

Ready to bridge the gap?

If you’re struggling to convert your team's design craft into business terms the Board respects, I can help. I have two 1:1 coaching spots opening this month for leaders ready to level up.

That’s it for this week.
