A strategy is a decision. Delivering it is a different kind of work, and it's where the value goes missing. Five phases take an organization from a defined problem to a result it can prove held.
A strategy is a decision. Delivering it takes a different kind of work: owners, sequencing, structures that let people act, and a way to tell whether the change held once the outside help left. The gap between the two is where value disappears.
McKinsey's research on transformations puts a number on it. Even companies that judged their transformations successful reported capturing about two-thirds of the potential financial benefit, and 55 percent of the value lost slipped away during and after implementation. Planning isn't where the money goes missing. Delivery is.
The Eighty Group Method is built around that finding. It has five phases, and each one ends with something a leadership team can see, test and use.
1. Define: agree on the problem and what it's worth
Programs stall when a team agrees on a solution before it agrees on the problem. Define produces a short problem statement and an estimate of the value at stake: what improves, for whom, and roughly what it's worth. That figure sets the ambition for the work and becomes the test for each recommendation that follows. If an idea doesn't move it, the idea waits.
2. Diagnose: score the breakdown before recommending anything
In a stalled program, every leader has a theory. Diagnose replaces theories with a scored view. Each of the four pillars has its own diagnostic: the Execution Gap Diagnostic for strategic implementation, the Decision Rights Diagnostic™ for organization design, the Process Debt Index™ and CORES™ for operations, and the Integrated Experience Index™ for service across customers, employees and channels. Each one shows which part of the organization is failing and by how much, and ranks the breakdowns by impact. A leader leaves this phase knowing where to act first and, just as useful, where not to spend effort.
3. Design: build the future state with the people who will run it
A design handed down from outside doesn't survive contact with the work. Design builds the future state and the roadmap with client teams in the room: the operating model, the decision rights, the redesigned workflows, the service model. Through the Gap-to-Action Playbook™, each low score becomes a tiered action with a named owner. The roadmap that comes out has one owner per initiative and a sequence the organization can carry, not a list of every fix that would be nice to have.
4. Implement: deliver in 90-day waves
Long programs lose momentum because results arrive too late to keep people committed. Implementation runs on the 90-Day Execution Cadence™: three visible waves of work, each re-scored at its checkpoint. Leadership watches the diagnostic scores and business measures move in a live Performance Scorecard at each 90-day review. When a wave doesn't move the score, the team finds out in weeks and adjusts, instead of learning at year end that the plan didn't land.
5. Sustain: hand over, then check whether it held
Sustain exists for the value that slips away after implementation. It closes with a handoff package that lets the client team run the work without outside support: owners, routines, measures, and the governance rhythm that keeps them honest. The Sustainment Index™ runs on every engagement and runs again after handover, to test whether the change is holding or quietly reverting. If it's reverting, the re-score shows where.
Planning isn't where the money goes missing. Delivery is.
What a leader gets
Across the five phases, a leadership team gets three things a roadmap alone can't provide: a measured starting point, a named owner for each action, and proof, at each checkpoint and after handover, that the change is real. The method stays the same whichever pillar the work sits in. What changes is the diagnostic that opens it.
Where to start
If you know execution is breaking down but not where, start with the diagnostic for the pillar closest to the pain. The How We Work page lays out the pillars and the diagnostic behind each one.
