Promised Value vs. Proven Value: The Shared Value Plan

Most value selling stops the moment the deal closes. The business case that won the deal goes in a drawer, and a year later nobody can say whether the value was real. Promised value and proven value are two different things, and the gap between them is where renewals quietly die.
The promise outlives its proof
In the sales cycle, value is everywhere: the ROI model, the business case, the number that justified the purchase. Then the deal closes and the value story goes quiet. The team moves to the next deal, the customer moves to implementation, and the promise that closed the deal is never measured against what actually happened.
That is a problem, because the promise was a forecast and the renewal depends on the result. When the renewal conversation arrives and someone asks what the customer actually got, a confident answer is rare, because nobody set up the measurement when the deal was won.

What a shared value plan is
A shared value plan is the artifact that carries value from promise to proof. It is not a slide; it is a living agreement with four parts.
A signed, dated baseline
Where the customer stands today, agreed by both sides before anything changes. Without a baseline, improvement is unprovable, because there is nothing to measure against.
Outcome metrics tied to their objectives
Three to five measures that matter to the customer, not vanity numbers, each with a defined source and a named owner. These are the terms on which value will be judged.
A cadence, not a QBR
A regular value review that checks progress against the baseline, replacing the status-update QBR with a conversation about whether the promised value is showing up.

Metrics | Vanity or generic | The customer's objectives |

Make value a living record, not a document
The reason value plans fail is capacity: keeping a baseline, metrics, owners, and a cadence current across every account is more than a value team can do by hand, so it does not happen. This is where the work has to scale. Spotlight treats the value case as a living record grounded in the evidence, carrying the baseline and outcomes forward from the deal into the relationship, so proving value becomes something the system maintains rather than something a person reconstructs before a renewal.
Promised value wins the deal. Proven value wins the renewal and the expansion. The shared value plan is what connects them, and keeping it alive is what separates a value story from a value result.
Treat the promise as a forecast. The renewal depends on the result.
Set a signed, dated baseline. Improvement is unprovable without one.
Tie metrics to their objectives. Not vanity numbers, with named owners.
Replace the QBR with a value review. Check the promise against reality.
Keep the plan alive. A living record, not a document in a drawer.
FAQs About Shared Value Plans
What is a shared value plan?
A shared value plan is a living agreement that carries value from promise to proof. It has a signed, dated baseline, three to five outcome metrics tied to the customer's objectives with named owners and sources, and a regular value review that checks progress rather than a status-update QBR.
What is the difference between promised value and proven value?
Promised value is the business case that wins the deal, a forecast of the outcome. Proven value is what the customer actually got, measured against a baseline. The gap between them is where renewals weaken, because the promise is rarely measured after signature.
Why does value selling stop at the close?
Because the sales motion is built to win the deal, and once it is won the team moves on. Without a baseline and metrics set up at close, there is nothing in place to measure, so the promise is never checked against reality.
Why replace QBRs with value reviews?
A status-update QBR reports activity. A value review checks the promised outcomes against the signed baseline, keeping the conversation on whether the value the customer bought is actually showing up, which is what the renewal will turn on.
How do you keep a value plan alive across every account?
By capacity, which is why most fail by hand. Spotlight treats the value case as a living record grounded in evidence, carrying the baseline and outcomes from the deal into the relationship so proof is maintained by the system rather than reconstructed before a renewal.
