Lead vs Lag Indicators

Two kinds of numbers

Every measurable in your plan is one of two kinds. Lag indicators are outputs: they tell you whether you got the result, and they arrive too late to change anything — by the time MRR is on the dashboard, the quarter that produced it is spent. Lead indicators are inputs: they measure behavior that is predictive of the result and directly within your influence, and they're available immediately.

The distinction isn't exotic — it appears in The 4 Disciplines of Execution as 'lead and lag measures' and runs through the 12-week methodology under the same names. What the 12-week system adds is an insistence on where each belongs: lag measures on goals, lead measures on the weekly scorecard.

Why you can only act on lead measures

You cannot decide to have more revenue this week. You can decide to make ten outreach touches today. That asymmetry — results are influenced, actions are controlled — is the entire case for lead measures. Managing to the lag measure feels rigorous but is operationally empty: staring at an outcome gives you no Tuesday-morning instruction.

Lead measures also fail gracefully. If you execute your lead measures at a high level and the lag measure still doesn't move, you've learned something precise: the tactics are wrong, not the effort. Without lead measurement you can't distinguish a strategy problem from an execution problem — which is why so many teams argue about results they never instrumented the causes of.

• Sales — lag: new MRR closed. Lead: outreach touches sent, discovery calls held.
• Fitness — lag: body weight, 5k time. Lead: workouts completed, meals logged.
• Content — lag: organic signups. Lead: articles published, pages updated.
• Fundraising — lag: round closed. Lead: investor meetings booked per week.
• Hiring — lag: role filled. Lead: candidates sourced and screens held per week.

Tactics are your lead measures

In a 12-week plan the mapping is exact: the lag measure lives on the goal ('$30k MRR by week 12'), and every well-written tactic is a lead measure ('10 outreach touches daily'). This is why the Friday test matters so much — a tactic that can't be counted can't function as a lead indicator, and the causal chain from weekly behavior to quarterly result breaks.

It's also why the weekly execution score is computed from tactics rather than results. Scoring lead measures weekly gives you a fast, controllable feedback loop; the lag measures get checked along the way, but they render a verdict only at week 12. Chapter 6 shows how that weekly scorecard works mechanically.

Keeping both honest

Lead measures have one failure mode worth guarding: proxy drift. If 'articles published' stops correlating with signups, publishing more is motion without progress. The safeguard is the weekly review — glance at the lag measure's trajectory each week, and if several weeks of strong lead execution haven't budged it, change the tactics, not the goal.

Held together, the two indicator types give you the full loop: leads tell you what to do today, lags tell you whether the theory behind the plan is true. A 12-week cycle is short enough to run that loop four or more times a year, which is where the compounding comes from.
