Customer Success Operations — the glossary

All 125 terms from the book’s appendix, defined exactly as the volume uses them. Published in full.

Accepted intake: An intake result in which required evidence is complete for the selected onboarding path.
Activation: The dated decision that accepted evidence supports the first primary outcome under the published rubric, with reviewer, provenance, confidence, and exceptions preserved.
Activation Rate by Horizon: Accounts activated by a declared horizon divided by eligible accounts with enough observation time to reach that horizon, with open observations, pre-activation exits, exclusions, and missing evidence reported separately.
Activation Timing: The point at which activation is recorded, measured from the published start event. Use closed-won only when the company has explicitly selected and defined it as that start event.
Activity: A supplier or customer action that may enable an outcome but does not by itself demonstrate the intended customer change.
Adoption: Repeated evidence of intended use or an outcome across a declared period. State whether customer operation, supplier service, or both produce the evidence.
Adoption breadth: The distribution of intended use or outcome evidence across the users, roles, teams, locations, or workflows relevant to the offer. Whether greater breadth lowers risk is an offer-level hypothesis.
Adoption Cadence: The expected frequency with which the primary outcome should occur, defined at the offer level.
Adoption decay: A decline in outcome or intended-use evidence relative to the expected cadence. Treat it as a candidate risk signal and investigate alternatives such as seasonality, role change, service design, customer choice, or measurement error.
Adoption persistence: Repeated achievement of the intended-use or outcome threshold across declared windows.
Adoption signal: Product, service, customer, or reviewer evidence used to infer that intended use or an outcome recurred, with source and confidence preserved.
Adoption window: A bounded time interval during which the outcome is expected to occur at least once.
Assisted adoption: Outcome recurrence that depends on repeated supplier intervention. This may be expected in a managed service; compare it with the offer design, customer expectations, service cost, and evidence plan before labeling it fragile.
Auditability: The ability to trace reported metrics and states back to underlying evidence and timestamps.
Calibration: Comparison of prior predicted probabilities with observed outcome frequencies in comparable cases.
Capacity Limit: A documented point at which the current scope, access, or functionality is hypothesized to constrain additional value. It is one possible expansion input, not a universal gate.
Capacity-led expansion: Added scope intended to relieve a documented seat, volume, access, or functionality limit.
Censored TTV observation: An eligible account whose activation endpoint is not observed by the declared as-of date. Report elapsed time through that censor date without treating it as a completed TTV.
Churn: The termination of a contract at renewal or earlier.
Churn event: Contract termination at renewal or earlier under the published cohort rule.
Churn Reason: A provisional classification used to group evidence and hypotheses about why a contract did not continue. It is not proof of causation and should allow secondary codes, conflicting evidence, and “unknown.”
Classification: A coarse label used to select a response owner and route without claiming a diagnosis.
Closed-won: The terminal opportunity status recorded after a binding agreement or policy-approved order satisfies the counsel-approved execution-evidence gate. It does not establish admission to the management bookings report under the written policy, recognition as accounting revenue, billing, cash, delivery completion, or handoff acceptance.
Closed-Won Intake: The gated process that validates execution readiness after a deal enters closed-won.
Cohort: A group of contracts aligned by start period, offer, or execution context for comparative analysis.
Completed TTV observation: A time-to-value record whose first-outcome evidence has been accepted under the published activation rule.
Complexity Class: A categorization reflecting execution difficulty due to integrations, data migration, scale, or regulatory constraints.
Conditionally accepted intake: An intake result permitting bounded work while an approved exception or owned open item remains.
Consolidation expansion: Added scope intended to replace another vendor, simplify procurement, or standardize operations.
Constraints: The dependencies, customer responsibilities, and known risks that bound execution.
Contraction: A reduction in contract value without termination.
Controlled experiment: A bounded pilot or add-on with a declared population, term, spend, support, acceptance criteria, and exit.
Customer lifetime value (CLV): An estimate of the discounted present value of future customer contribution after variable costs under locally stated assumptions.
Customer relationship management (CRM): Software that stores selected customer-facing records; it does not determine the truth of a contract, outcome, or accounting conclusion.
Customer-facing trust: The customer's reasonable ability to understand the supplier's promise, evidence, uncertainty, responsible owner, and correction path. It is operated through transparent records and responses, not inferred from a health color.
Decision rights: The recorded authority to approve, reject, or change a decision.
Dependency Concentration: The degree to which value realization depends on a narrow set of individuals, workflows, or manual effort.
Diagnosis: The current cause hypothesis guiding a recovery test; it is not a proven mechanism.
Direct signal: Evidence that closely represents the intended outcome rather than a related activity.
Escalation: The controlled transfer of responsibility or authority when risk exceeds defined thresholds.
Escalation Window: The maximum duration a risk may remain unresolved at a given response level before further authority is required.
Evidence: An inspectable source used to support or challenge a state or outcome claim, including telemetry, service records, work records, customer attestation, and reviewer judgment under a written rubric.
Expanded contracted value: An increase from an existing customer supported by a documented incremental-value and economics case.
Expansion: An increase in contracted value from an existing customer, supported by a documented expansion pathway and incremental value hypothesis.
Expansion eligibility: The review state in which the incremental outcome, pathway, customer capability, economics, unresolved risk, approvals, and evidence plan have been documented.
Expected path: The versioned, dated sequence implied by the offer, accepted intake conditions, onboarding plan, time-to-value window, and adoption cadence.
Expected Path / Expected Trajectory: A published reference process or set of expected state conditions for an offer and assumption set. It supports comparison but does not require every customer to follow one sequence.
Expected Time Window: The normal range within which a state transition should occur under defined conditions.
Expected TTV window: The internal planning range for time-to-value for a declared offer and material complexity class.
Expected window: The planning range for a milestone under declared conditions, used as a review trigger rather than a customer promise.
Explainable churn: A non-continuation record with enough preserved facts, statements, alternatives, and decision history to support investigation without claiming cause.
Exposure window: The interval from the published start event to accepted first-value evidence. It is an operating measure, not proof that no value existed earlier and not an accounting definition of revenue.
False activation: An activation decision recorded without evidence sufficient under the published rule.
Feedback Loop: A route by which observed post-sale results reach an authorized owner who records a change, no change, bounded test, or request for better evidence.
First value: The first instance in which the primary outcome occurs under real operating conditions.
Forecast Resolution: The comparison of a prior risk estimate or scenario with the later discrete renewal outcome. The outcome supports calibration but does not reveal causation, and a score is not a probability unless calibrated.
Graceful exit: A documented decision to stop recovery while preserving communication, transition obligations, and learning.
Gross revenue retention: The percentage of starting recurring contracted value that continues into the next period before accounting for expansion.
Handoff record: The structured, persistent record of what was sold, the relevant agreement source, assumptions, open questions, customer confirmations, owners, and intake decisions.
Health model: The declared signals, transformations, weights or tier rules, thresholds, review cadence, limitations, and owner judgment used to estimate a named customer or commercial outcome.
Health Score: A reproducible summary of selected renewal-risk signals. Call it a probability only when calibrated against comparable observed outcomes.
Health Trend: The direction and rate of change of the health score over time.
Implementation assumptions: The integrations, migration, access, and other operating conditions assumed for execution.
Intervention: A deliberate response intended to change an observed risk condition under a stated evidence and review plan.
Issue: A discrete problem requiring resolution, often surfaced explicitly by the customer.
Milestone: A verified state transition within onboarding indicating progress toward activation.
Net revenue retention (NRR): (Starting recurring contracted value - churned value - contraction + expansion) / starting recurring contracted value, calculated for a declared cohort, period, currency, amount basis, and effective-date rule.
New-use-case expansion: Added scope for a different requirement with its own users, outcome, prerequisites, and evidence.
Offer: The bounded commercial unit being sold, defining scope, outcomes, pricing, and constraints.
Onboarding architecture: The reusable execution path that sets how customers move from contract start to activation, including dependencies, evidence, expected windows, owners, and permitted variation.
Onboarding completion: The state in which onboarding milestones are complete, distinct from activation.
Onboarding cycle time: Elapsed time from onboarding initiation to onboarding completion under published event rules.
Operational Definition: A definition that specifies how a signal or state is generated, observed, and classified, including a rubric and provenance when judgment is required.
Outcome: An observable customer change treated as evidence of value from an offer, with the plausible contribution, alternatives, evidence, and judgment limits stated.
Outcome definition: The customer change sold as the reason for purchase and the evidence intended to test it.
Outcome hierarchy: A dependency graph of outcomes and prerequisites. It can contain ordered paths, parallel branches, and join conditions.
Outcome saturation: A documented hypothesis that current scope or capacity constrains additional outcome improvement. It is one possible expansion input, not a universal readiness gate.
Period: A bounded time interval aligned to renewal, billing, or evaluation.
Pricing definition: The amount, billing cadence, and discount structure carried from the approved agreement.
Primary outcome: The customer change currently treated as the offer's main value hypothesis. It is an input to economic review, not proof that continuation is justified or unjustified by itself.
Proxy: A signal expected to relate to an outcome and therefore requiring validation before it substitutes for direct evidence.
Reach expansion: Extension of an existing use case to a new team, geography, business unit, or population.
Recoverable risk: A dated estimate that value can plausibly be restored within the remaining term and approved economics.
Recovery window: The bounded period during which a save motion may attempt to restore value persistence.
Recurring contracted value: The amount admitted under the company's written management rule for recurring contractual scope, with term, currency, inclusions, exclusions, and change treatment declared.
Renewal: The contractual decision event in which a contract continues, changes, or terminates.
Renewal forecast accuracy: The difference between forecast renewal outcomes and later actual renewal outcomes under the same rules.
Renewal mechanics: The dates, evidence checks, authority, and commercial steps used to prepare and execute a renewal decision.
Renewal readiness: A dated evidence snapshot used to prepare the continuation decision, including known gaps and conflicting evidence. It is not a certification that continuation is predetermined or economically correct.
Renewal window: The time period during which renewal decisions become procedurally and economically actionable.
Repetition threshold: The required number of observation windows containing evidence under the published adoption rule.
Retained contracted value: Starting recurring contracted value that continues into the next term without reduction.
Retention: The continuation of recurring contracted value into the next period under the published cohort rule.
Return on investment (ROI): A comparison of a defined gain with a defined investment under locally stated assumptions.
Returned intake: An intake result in which a material condition blocks the proposed work and returns a reason and next action to the source owner.
Revenue Decay: This book's operating hypothesis that expected future contracted value may weaken over time. Product fit, customer capability and incentives, budget, leadership, competition, market change, commercial terms, and measurement error are credible alternatives to a value-realization explanation.
Revenue Design: The work of deciding what an offer promises, to whom, and under which constraints and economics.
Revenue Durability: An evidence-bounded assessment of whether contracted value continues across declared periods, interpreted with the offer's expected service level, intervention cost, concessions, customer conditions, and uncertainty.
Revenue Durability Evidence: The cohort records used to assess whether contracted value continues across declared evaluation periods, with expected and exceptional intervention, concessions, cost, concentration, and limitations visible. This is an operating construct, not recognized revenue.
Risk: An observed condition or deviation hypothesized to affect non-renewal, contraction, concession, customer value, cost, or another declared outcome.
Risk Classification: The assignment of detected risk to a finite category that determines response routing.
Risk Detection: The method for identifying deviation before outcomes resolve through automated or human evidence with provenance.
Risk prevalence: The percentage of an eligible account population occupying declared risk states.
Risk register: The persistent record of detected risks, classifications, owners, and status.
Risk Threshold: A predefined boundary beyond which deviation becomes actionable.
Rubric: A written set of criteria a reviewer applies when evidence requires judgment.
Sales Operations: The function that maintains the sales-stage records, rules, and approvals carrying an opportunity through closed-won.
Save motion: A predefined, bounded intervention sequence attempting to restore value persistence.
Scope definition: The included and excluded product or service scope carried into post-sale work.
Secondary Outcome: An outcome that increases value but is not required to justify baseline continuation.
Service levels: Published service-response or performance targets owned by the responsible service function.
Signal: An observable event, statement, work record, or documented judgment used to inform a state or risk estimate, with source and confidence preserved.
Sponsor: The customer-side person responsible for supporting the change and resolving internal barriers.
Stakeholder map: A record of who must participate for value realization and what each person can decide.
State: An observable condition within one declared state dimension. An account can hold concurrent onboarding, risk, commercial, and renewal states.
State Transition: A recorded change within one declared state dimension, supported by accepted evidence and, where needed, reviewer judgment.
Success criteria: The published evidence or rubric that will be treated as value realized.
Term definition: The agreement start date, end date, and renewal structure relevant to post-sale decisions.
Terminal risk: A condition indicating that recovery is improbable or uneconomic under current constraints.
Threshold: A published score, probability, or evidence boundary that triggers a specific response.
Time-to-value (TTV): The elapsed time from a published start event to activation; the start-event definition must be named with the metric.
Unassisted adoption: Outcome recurrence without supplier work beyond the contracted operating model.
Value persistence: The continued occurrence of outcomes across successive periods.
Verification: The review decision that determines whether available evidence meets the published outcome rule.
Weight: The declared strength with which a signal changes a rule-based score or statistical estimate.
