Preserve the value hypothesis
A business case connects the customer current state, expected improvement, investment and risks. Post-sale value realization begins by preserving those elements, assigning owners and replacing assumptions with customer evidence as implementation progresses. This creates continuity between the buying decision and later value reviews.
What should carry forward from the sale
A handoff built around notes and product requirements loses much of the economic context behind the decision. The post-sale team needs the parts of the case that explain what the customer expects to change and how that change will be recognized.
Current-state baseline
Keep the starting performance, reporting period, data source and customer owner for every measure used in the case.
Value drivers and formulas
Retain the logic that connects operational change with financial or strategic impact.
Agreed assumptions
Record the improvement rate, adoption level, timing and dependencies that shaped the expected outcome.
Stakeholder commitments
Capture who approved the case, who supplies evidence and who will use the result in later decisions.
Turn each value driver into a measurement plan
Every material value driver needs an observable signal. The measurement can combine customer data, product data and documented evidence. The plan should state how often the measure changes and when the customer expects to review it.
| Business-case element | Post-sale treatment | Example evidence |
|---|---|---|
| Baseline | Validate before or during implementation | Prior-period operating report or customer-approved estimate |
| Improvement assumption | Translate into an operational target | Cycle-time target, conversion target or risk reduction |
| Adoption dependency | Track as a leading indicator | Usage, workflow completion, coverage or trained users |
| Financial impact | Recalculate with observed results | Hours released, revenue added, loss avoided or cost removed |
| Timing | Connect to milestones and review dates | Go-live, adoption checkpoint, QBR and renewal |
Handoff example: the approved request-processing case
Illustrative handoff dated January 1, 2027. This continues the hypothetical business-case brief. For this stage of the example, assume the sponsor has approved version 1 after finance validated the baseline and costs. All approvals, roles and USD amounts are fictional; named receiving owners would be required in a real record.
The plan covers January-December 2027. Implementation occupies January-March; go-live is April 1. The first outcome review is April 30, followed by a June 30 QBR. Expected benefits remain estimates until evidence becomes available.
| Approved assumption | Receiving owner | Post-sale measure | Evidence still missing | First review |
|---|---|---|---|---|
| 10,000 requests/month; 6 minutes per request | Operations lead and process analyst | Monthly volume and matched handling-time samples | Post-launch sample using the same task definition | April 30, 2027 |
| 75% adoption; 2 minutes saved on adopted requests | Operations lead | Adopted requests / eligible requests; handling time on adopted work | Workflow logs and a representative time study | April 30, 2027 |
| 40% of released hours removes paid support at $40/hour | Finance partner | Purchased support falls from 400 to 300 hours/month | Approved post-launch invoice and confirmation of unchanged rate and scope | April 30, 2027 |
| $30,000 investment; $36,000 first-year cash benefit; 20% simple ROI | Customer sponsor and finance partner | Cumulative cash benefit against actual investment | Actual implementation costs and monthly benefit evidence | June 30, 2027 |
Build continuity into the customer journey
The strongest handoff is a continuation of the same customer conversation. The account team can update the case as delivery changes the facts and as the customer contributes better evidence.
Review the approved case
Bring Sales, implementation, Customer Success and the customer sponsor together around the final assumptions and expected outcomes.
Attach actions to value drivers
Connect milestones and adoption activities with the specific result they are expected to influence.
Replace estimates with facts
Update the model as customer data becomes available and keep the source and date visible.
Prepare the next decision
Use the current evidence to support executive reviews, renewal, expansion and the next value hypothesis.
Preserve the approved baseline when the forecast changes
Keep version 1 of the approved case with its approval date and evidence. Add actual results as dated observations. A new adoption forecast or revised target belongs in a separate revision with the reason, owner and customer decision recorded.
In the example, the June review finds 60% adoption and 4.5-minute handling time. Preserve the original 75% adoption and four-minute targets so reviewers can see the shortfall. Record a recovery plan and any revised forecast alongside them. A revised forecast should not overwrite the starting six-minute baseline.
