SYSE.8:2 - Problem

A plausible technical product concept can coexist with an impossible provider concept. Recurring mismatches include promising availability without observing the relevant state, retaining ownership without financing or maintenance capability, automating access while transferring exception Work to users, and depending on partner Systems whose responsibilities and interfaces are not engineered.

Four failures recur in engineering descriptions: a business model omits bearer and interface constraints; a technical architecture description omits obligations and continuing Work; an SLA omits the actual provider arrangement; and a service blueprint is treated as evidence that provision will work. Use the descriptions needed for the bounded decision, with their claims and omissions explicit.
