Direct Incorporation
Inclusion of the exact text of one document into another, placing the content under the unilateral Configuration Control of the latter – that is, creating a stream of future changes applicable to the new document that is independent from the stream of future changes in the original reference. This represents a fork in the road... read more
Incorporation by Reference
Inclusion of a “pointer” in one document to specific information in another document, without inserting the actual content (see value). This admits to the possibility that changes to the former document may, at some future time, be relevant to the development or sustainment of the CI that is the subject of the former. Contrast with... read more
Interface Requirements Specification (IRS)
A type of specification unique to Software Systems Engineering, where the “interface” was originally a component (e.g., a Graphical User Interface), but that has been generalized to combine the concepts of ICD and Specification which were, in the hardware legacy, two completely different things.
Master Verification Plan (MVP)
The intent of an MVP is to describe the broad outlines of how verification is approached on a complicated program. The benefit of having a technically competent MVP is that it can provide context for the approach, showing how the major activities relate to each other. However, MVP’s can attempt to control too much detail,... read more
Multi-lateral ICD
A type of ICD having addressing characteristics jointly held by more than a single CI. Contrast with unilateral ICD.
Operational Requirements Document (ORD)
A legacy-practice collection of operational requirements, typically addressing the entirety of all developmental spirals and increments in a single document. Contrast with CRD.
Software Version Description (SVD)
A document (not a drawing) that describes a particular release of software, along with the instructions for installing it and adapting it to some specific locale or usage.
Standard
A set of processes and practices to accomplish some repeated non-project-specific type of task to some level of quality. Contrast with Specification.
Unilateral ICD
An ICD that establishes one side of an interface, where the other sides have no input (but must necessarily comply). Contrast with multi-lateral ICD.
