1 Document Scope
This document describes in engineering developm ent terms the definition of Bishop. This document will
define the engineering platform with enough detai l to meet the initial product concept while n ot
constraining the execution team on specif ic i ntricate design details.
This document is also a description of the functional behavior with sufficient detail in order to achi eve an
accurate quotation, begin writing user guides and to begin developing test methods.
1.1 Definition of Terms
Shall – Term indicates a required element, e.g., "the uni t shall play MP3 files".
Should – Term indicates a suggestion or preference, e.g., "the unit should attempt to read ID3V1 tags".
