Leadership operating rhythm based on EOS® experience

A simple management system that gets things done

Many leadership teams lose time to unclear priorities, long meeting minutes and to-do lists spread across different tools. Greenstone Consulting helps leadership teams put a simple, structured management system in place, with clear direction, focused priorities and real accountability.

Clear direction

A shared vision and plan, from long-term goals down to the next 90 days, so everyone knows where the company is going.

Accountability

A clear owner for every role, priority and key number, so it is always clear who is responsible for what.

Management focus

A small number of quarterly priorities keeps leadership attention on what matters most.

Everything in one place

One plan, one scorecard and one issues list replace long minutes and scattered to-do lists.

How an engagement runs

  1. Leadership workshop

    Align the leadership team on vision, goals and the plan for the year and the quarter.

  2. Blueprint and tools

    Practical templates for the plan, scorecard, priorities and meeting agenda, ready to use.

  3. Quarterly priorities (Rocks)

    Set and agree the Rocks for the next 90 days, each with a clear owner.

  4. Weekly leadership meeting

    A short, structured weekly meeting, with Greenstone taking part in the first meetings.

  5. Quarterly reviews

    Facilitation of the first quarterly sessions to review results and set the next priorities.

Built on hands-on experience of running EOS® as part of a leadership team. Suited to startups, growth companies, state lotteries and gaming operators that want a simpler way to manage and get things done.
