Run well an LBE gives leadership a current, accurate read on performance and a clear basis for decisions. Run poorly, it becomes a mechanism for resetting expectations downward while performance gaps quietly widen.

Drawing on the expertise of J+D Forecasting, this article examines the Latest Best Estimate process: how to run one that drives real decision-making through the year, and the discipline failures that undermine even well-structured processes.

The article covers:

  • How to maintain a continuously evolving base case that a fixed reference point
  • How to set the right LBE cadence, and when to change it
  • Why variance analysis only feeds forward when teams treat it as learning, not accountability
  • What makes a risks and opportunities register useful to decision-makers
  • How to stop the LBE becoming a vehicle for expectation management

Frequently Asked Questions

An LBE is an in-year forecast that tracks commercial performance against the Annual Operating Plan baseline. It is updated on a regular cadence, monthly or quarterly in most markets, and weekly in high-scrutiny markets like the US, recalibrating assumptions as new actuals arrive. The AOP remains the fixed baseline, and the LBE measures performance against it.

The AOP sets the strategic and financial baseline for the year: agreed targets, assumptions, and accountability structure. The LBE is the in-year mechanism that tracks how the year is actually landing against that baseline. A common and costly mistake is allowing the LBE to absorb the bad news and effectively replace the AOP as the primary reference point, which removes the ability to hold performance accountable against the original commitment.

Cadence depends on the brand’s lifecycle stage and market dynamics. Monthly is well-suited to newly launched or fast-growing brands where commercial activity is at its highest and a surprise late in the quarter is expensive to correct. Quarterly works for more established brands in stable markets. In the US, where data availability is high and commercial scrutiny is intense, weekly cycles with daily data inputs are common. The right frequency gives decision-makers current enough information to act without absorbing more analyst time than the output justifies.

Two things matter. The original AOP must be structurally locked and version-controlled separately from the LBE working file, so it cannot be quietly overwritten as results deteriorate. And governance needs to make the gap between the LBE and AOP visible at every review, not just the LBE in isolation. Visibility of that gap is what creates accountability. Where it is hidden, expectation management happens without anyone explicitly choosing to let it.
