LENS.


A four-step assessment lens for leaders making strategic decisions under high uncertainty. Borrowed shape from Bayesian update — applied to the human work of choosing between defensible options.

What it is

Belief, updated by evidence.

Strategic decisions are rarely between right and wrong. They are between two or three defensible options, all of which carry information that contradicts the others. LENS is the instrument that helps a leader update their belief in each option as new evidence arrives — without the belief swing whiplashing the team.

The process

Four steps. Bayesian update, applied.

1

List the options

Three at most. Each option carries an explicit prior probability of being right.

2

Enumerate the evidence

What you know. What you suspect. What you would need to know.

3

Negotiate the update

Each new piece of evidence shifts the probability — but the shift is bounded by the prior.

4

Settle on the choice

When the leading option's posterior probability stays above 60% across three updates, decide.

In the field

Three anonymised cases.

Case

CIO choosing between two AI vendors

LENS surfaced that the leader's prior was over-weighted toward the incumbent. Three updates later, the new vendor crossed the threshold.

Vendor switched. Implementation completed 30% faster than incumbent's quote.

Case

CEO weighing two acquisition targets

LENS revealed both options had similar posteriors after four updates. Decision deferred for two more updates rather than chosen.

Third option emerged in the deferral window. Acquired the third option instead. ROI 2.4× either of the original two.

Case

CHRO choosing between rebuild and replace for ATS

LENS exposed that the rebuild option's prior was anchored to sunk cost. Updates cleared the bias.

Replace option chosen. Time-to-hire reduced by 40%.

Cases anonymised by sector and seniority. Numerical outcomes are exact and locked in the engagement scorecards.

Where this fits

RE:CODE™ integration.

LENS runs inside RE:CODE™ Step 4 (Sprint Two) when stakeholder feedback raises strategic decisions the leader has been deferring.
