Documenting a Digital Service Model from Sales to Operation

What must a service model capture from the sales phase to ongoing operation?

The model must document the target state, prerequisites, modules, pricing rules, handovers, acceptance, and ongoing responsibility. Each order version references a valid version so that sales and operations interpret the same commitment.

Common definition

• Complete value chain Sales, onboarding, delivery, acceptance, and operations each specify input, output, and owner.

Complete value chain

• Order deviations resulting from conflicting service definitions.

• Product changes without a clear assignment to affected offers and existing orders.

Demarcation case: "Sales-Operations Gap"

Sales selects a product version from which offers and operational tasks are generated. If a price or acceptance rule changes later, the existing order remains at the agreed-upon version, while new offers use the released version.

Versioned scope

1. All visible commitments and internal delivery rules are assigned to a common result tree.

2. Modules, prices, handovers, and acceptances are assigned owners and have binding versioning.

3. An order is reconstructed from the initial inquiry to operation based on the documentation and checked for gaps.

Sales Operations Gap

• Sales Operations Gap – A sold feature has no deliverable process or responsible role.

• Version without order – After a product change, it is no longer possible to determine which version applies to an ongoing contract.

• Document without effect – Teams continue to maintain their own lists, even though a central definition exists.

Conclusion: End-to-end documentation of service models

A digital service model connects promises and delivery capabilities across the entire lifecycle. Versioning prevents product changes from retrospectively creating conflicting expectations.
