Welcome to the first edition of The Behavior Brief presented by 1st90!
Every organization has a strategy. Far fewer see it translate into consistent action, sustained momentum, and measurable results. At 1st90, we’ve learned that transformation doesn’t fail because leaders lack vision—it fails because behavior change is treated as an afterthought. This newsletter exists to change that. Each week, we’ll break down the small, observable behaviors that actually move performance, demonstrate how they show up inside real work, and share one practical action you can apply immediately to accelerate change—without adding meetings, tools, or noise. So without further ado, let’s get into it.
Strategy Isn’t the Problem…
Behavior Is
Most transformations don’t fail because the strategy is wrong.
They fail because Monday morning shows up—and people keep working the old way.
Leaders can describe the future-state with impressive clarity: a new operating model, a sharper customer promise, faster decision cycles, a more empowered frontline, a modern data platform. The “What” is often solid. The slide deck is coherent. The business case is rational.
And then… adoption stalls. Momentum fades. Execution fragments by function. The initiative becomes a program name instead of a new way of working.
McKinsey has pointed out for years that a large share of transformations don’t achieve their intended outcomes—often cited around the “70%” range—despite heavy investment in planning, governance, and communications. McKinsey & Company BCG’s recent work similarly notes that only about a quarter of transformations successfully create value—meaning most efforts burn real calories without converting them into sustained performance (BCG+1).
That gap isn’t a strategy gap. It’s a behavior gap.
Behavioral Truth
Transformation is not a decision. It’s a repeated action.
Organizations love to treat change like a launch: announce it, train it, roll it out. But transformation is closer to habit formation at scale. It requires thousands of small choices—how leaders run meetings, how teams escalate decisions, how managers coach, how priorities get traded off under pressure.
And under pressure, people don’t rise to the level of the strategy. They fall to the level of their defaults.
That’s why change efforts so often “make sense” and still don’t stick. Because sense-making isn’t the same as behavior-making.
McKinsey’s Influence Model is a helpful lens here: transformations succeed when they focus on changing mindsets and behaviors through four levers—role modeling, fostering understanding and conviction, reinforcing mechanisms, and skills. McKinsey & Company Notice what’s missing: more decks. More slogans. More workshops. The levers are behavioral and environmental - what people see, do, get rewarded for, and practice repeatedly.
And as behavior researchers like BJ Fogg remind us, behavior changes when people have sufficient motivation, ability, and prompts - especially in the moments that matter. If the new behaviors are hard, unclear, or un-cued in the flow of work, they won’t happen consistently - even if everyone agrees they should.
Proof / Practice
Why “great programs” still fade. Most organizations run transformation support like this:
Define the strategy
Create a capability program
Train the leaders
Publish the playbooks
Hope the organization “adopts”
But hope is not a mechanism.
At 1st90, we name the real problem plainly: “Most transformations fail not because of strategy, but because behavior doesn’t change day to day.”
That shows up in a pattern partners recognize immediately: a leadership offsite creates alignment and energy; a rollout creates short-term motion; and then the organization returns to familiar rhythms - calendar pressure, old incentives, legacy ways of escalating decisions. The initiative becomes something people support, not something they do.
The difference between “we’re transforming” and “we transformed” is whether the organization can answer one question:
What will people do differently this week, and how will we reinforce it next week?
Application / Lesson
Treat behavior as the unit of transformation. If you want transformation to stick, stop treating behavior change as a downstream effect of the strategy. Treat it as the work.
A practical shift:
Instead of “launching a new operating model,” define 3–5 observable behaviors that make the operating model real.
Instead of “training leaders,” embed micro-actions that leaders practice inside real meetings, 1:1s, decision reviews, and frontline routines.
Instead of “measuring sentiment,” measure behavior adoption: frequency, consistency, and where it breaks under pressure.
That’s why 1st90 is built as an execution layer - not content-first, not an LMS, not another survey tool. It operationalizes behavior change through a simple loop: target behaviors → daily micro-actions → in-the-flow reinforcement → measurement → adjustment.
When behavior becomes visible and reinforced, transformation stops being a campaign and becomes an operating rhythm.
Closing Signal
Strategy sets direction. Behavior determines arrival.
If your transformation is stalling, don’t rewrite the strategy deck.
Rewrite the default behaviors—and make the new ones easier to do on Monday morning.
