We are embarking on our first 90 days of EOS® with an implementer. What are the non-negotiable behavioral milestones our leadership team must hit during this initial period to prove we are actually adopting the system?

The first 90 days are not about achieving perfection. They are about establishing new operational muscle memory. During this initial phase, your success is measured by three non-negotiable behavioral milestones. First, your leadership team must run a weekly Level 10 Meeting™ at the same day and time every week, starting and ending on time, without exception. This establishes the organizational heartbeat. Second, you must have a functioning weekly Scorecard with at least five to fifteen high-level activity metrics that are updated before the meeting begins. Third, every leader must own at least one individual Rock and report on its status weekly with a simple on track or off track. If your team is still rescheduling meetings, showing up with an unpopulated Scorecard, or giving lengthy explanations instead of binary updates by day 90, you have not actually begun implementing the system. You are just talking about it. The primary goal of the first 90 days is to build the discipline of accountability. It requires letting go of old, chaotic habits and submitting to the structure of the tools. Do not worry about whether your metrics are perfect or if your Rocks are scoped flawlessly. Focus entirely on the consistency of the habits. Once the rhythm is locked in, the data and results will follow naturally.
