01 / EXECUTIVE SUMMARY

The outcome is only the beginning.

Consumer opposition led to the return of the original formula as Coca-Cola classic. [1]

THE PRINCIPLE TO CARRY FORWARD

Test the proposed market action, including loss of the existing option, rather than a narrower attribute preference.

02 / THE PROMISE

What the system was trying to do.

Re-energize a major beverage brand by changing its formula.

Museum interpretation

The assumption beneath the promise

Museum hypothesis to examine: Preference for one attribute predicts response to the complete market decision. This is an analytical proposition to test against the record, not an attributed statement by the organization.

Success should be assessed against the intended service and its safety, reliability, or integrity constraints. A headline outcome cannot tell us whether those constraints were visible, tested, or owned before the event.

03 / WHAT HAPPENED

A sequence, not a single moment.

The intended system

Re-energize a major beverage brand by changing its formula.

Source-backed synopsis

The event or review

Consumer opposition led to the return of the original formula as Coca-Cola classic. [1]

The documented aftermath

The company reintroduced the original formula. [1]

Source-backed synopsis
Timeline of documented milestones. Gaps are not evidence that nothing happened. Sources: [1]
04 / WARNING SIGNS

What could be seen at the time?

Documented in cited record

Taste preference alone did not capture the meaning customers attached to the existing product. [1]

Who could see it?

See the cited investigation for named teams and the information they held. The synopsis does not infer awareness by every stakeholder.

Why was it not enough?

Signals need interpretation, authority, and a route to action. This is an analytical question, not proof that a warning was deliberately ignored.

05 / KEY DECISIONS

Choices made within constraints.

Museum analysis: Replacing a familiar product was a different decision from offering a preferred taste in isolation.

Available alternatives

Pause, test, narrow the operating envelope, seek independent review, or build a recovery option. These are proposed analytical alternatives; feasibility at the time is not established.

Information available

Taste preference alone did not capture the meaning customers attached to the existing product. [1]

Incentives & constraints

Delivery pressure, cost, authority, and incomplete knowledge may shape a decision. Their specific weight is not established by this synopsis.

Risk accepted

Ask whether the relevant risk was recognized, who had authority to accept it, and whether affected people understood its implications.

06 / SYSTEM MAP

How conditions connected.

Select a node to inspect its evidence. Links show a proposed analytical relationship, not a measured causal effect.

Triggering event

Legend: numbered nodes = analytical categories; dashed arrows = proposed influence or propagation. Museum interpretation informed by the sources below. Feedback and omitted influences require further investigation.
07 / CONSEQUENCES

Beyond the immediate event.

The launch created consumer anger and disrupted the brand’s relationship with its customers. [1]

Categories identify documented or relevant consequences. Financial, human, and environmental totals are not estimated here when the source base does not support them.

08 / WHAT THE MODELS EXPLAIN

More than one lens.

Analytical lens

Goodhart’s Law

Examine how targeting a measure can weaken its relationship to the intended outcome.

In this case, use the lens to examine research mismatch. This application is museum interpretation, not a finding of the original investigation.

Limit: Introductory guide. This lens generates questions; it does not establish causation or replace case-specific evidence.

Analytical lens

Principal-agent problem

Study conflicts between delegated decision-makers and those affected by their choices.

In this case, use the lens to examine research mismatch. This application is museum interpretation, not a finding of the original investigation.

Limit: Introductory guide. This lens generates questions; it does not establish causation or replace case-specific evidence.

Analytical lens

Scenario planning

Explore multiple plausible futures to test assumptions and responses.

In this case, use the lens to examine research mismatch. This application is museum interpretation, not a finding of the original investigation.

Limit: Introductory guide. This lens generates questions; it does not establish causation or replace case-specific evidence.

09 / COUNTERFACTUALS

What could have changed the outcome?

Counterfactuals are hypotheses. They identify possible intervention points without claiming that a different choice would certainly have prevented the event.

INTERVENTION 2 / During early testing

Test the operating envelope

Exercise realistic boundary conditions and shared dependencies rather than validating components only in isolation.

Cost & feasibility

Requires time and independent review before commitment.

Likely effectiveness

May reduce exposure or consequences. Not quantified; feasibility and effect must be assessed against evidence available at the time.

10 / LESSONS

From hindsight to a usable practice.

FOR FOUNDERS

Test the proposed market action, including loss of the existing option, rather than a narrower attribute preference.

Before accelerating hiring or spending, name the assumptions that remain untested and set evidence thresholds for the next commitment.

11 / AFTERWARD

Recovery is another investigation.

The company reintroduced the original formula. [1]

A corrective action is evidence of a response; it is not, by itself, evidence that the wider pattern has disappeared.

12 / SOURCES & EVIDENCE

Follow the record.

Documented claims are linked to sources. Analytical applications, lessons, and intervention proposals are museum interpretation. This draft does not establish motives or a single complete causal explanation.
