Scaling Excellence to stay the world’s finest food hall

La Grande Épicerie de Paris intends to stay at the top of France’s premium food-retail market. Its 2025-2028 strategy sets that ambition, and GEP Excellence, one of its pillars, is the engine that executes it: making excellence repeatable and deployable at scale, for the future. And excellence starts with the head. With OpenDecide, GEP Excellence began at the top of the company.

Staying at the top is not a one-off push. After a century as a benchmark of French gastronomy, and with the momentum of a landmark Olympic summer behind it, the task for a 550-person business is to make excellence repeatable: an operating standard every team can carry forward, not a program that fades after launch. That is the job of GEP Excellence.

The logic of GEP Excellence is simple: excellence starts with the head of the company. So the first deployment was the 15-person leadership team, the CODIR, mandated to steer the whole company. Set the standard where the strategy is decided, then scale it from there.

“Excellence starts at the top. If the team that sets the strategy doesn’t work to that standard, nothing below it will.”

Giles Roderick, Director, La Grande Épicerie de Paris

How it works

The CODIR began with an OpenDecide scan, a shared, evidence-based read of how the team actually operated. It surfaced two root causes: misaligned objectives and unclear accountabilities. The team validated them together, then used the platform to run its own workshops, redesign its objectives and clarify who owns what. Seven months later, the team launched a new improvement cycle, and the progress it had made was revealed.

Over two cycles, the leadership team’s effectiveness rose from a standing start to nearly 80%, and the impact showed up where the business is measured.

Scaling Excellence for the future

With the leadership team as the proof point, OpenDecide is now being deployed across other teams.

For a maison that has stayed at the top for a hundred years, staying there next rests on an organization that can scale excellence, one team at a time.
