The Center Test: A Practical Way to Decide What Your Product Team Keeps, Kills, or Retests

Every founder eventually hits the same wall: too many signals, too little certainty, and a backlog full of ideas that all sound plausible. The instinct is to ask “what should we build next?” But there’s a sharper question hiding underneath it — one that Columbia Business School strategist Rita McGrath puts to CEOs before they touch a roadmap at all: what is this company actually centered on?

The Silence Before the Bad Decision

A founder runs a two-week test on a new onboarding flow. The numbers come back mixed — engagement up slightly, but a handful of users seem confused. In the debrief, one product manager wants to ship it. Another has doubts but says nothing, because the last time she pushed back, the conversation got tense and nothing changed anyway. The team ships. Three months later, they’re trying to figure out why adoption stalled — and nobody remembers that someone already saw it coming.

But sometimes the thing holding a company back isn’t a process at all. It’s a belief the founder is quietly protecting, dressed up as a sensible decision.
