Quarterly Rocks: How to Set Priorities That Actually Get Done

In EOS®, "Rocks" are your most important priorities for the quarter — the few things that have to get done. The name comes from the classic "big rocks first" metaphor. The concept isn't unique to EOS, though; every well-run company needs a short list of quarterly priorities. Here's how to set ones that actually get finished.

Fewer than you think

The most common mistake is too many. If everything is a priority, nothing is. Aim for 3–7 company Rocks per quarter, and only a handful per person. A long list guarantees a busy quarter and a disappointing one.

Make them specific and measurable

"Improve marketing" isn't a Rock. "Launch the new website and publish 6 articles by Sept 30" is. Each Rock needs a single owner, a clear definition of done, and a due date.

Connect them to the bigger picture

Rocks should ladder up to your annual goals and long-term vision. If a Rock doesn't move you toward where you said you're going, ask why it's on the list.

Review them weekly

Set Rocks quarterly, but check them in your weekly leadership meeting — on track or off track, no in-between. That cadence is what turns intentions into outcomes. (See our piece on the Level 10 Meeting.)

When priorities keep slipping

If Rocks consistently don't get done, the problem usually isn't discipline — it's too many priorities, fuzzy ownership, or priorities that don't connect to a clear plan. That's often where an outside guide earns their keep: helping you choose the right few and hold the line.

Whatever system you run, the principle holds: a few clear, owned, measurable priorities beat a long wish list every time. Want help building a rhythm that sticks? Schedule a discovery call.
