GPR-006 — Implementation Assumptions and Context

Go to Annex C: Requirements

The Submission SHALL identify the assumptions and provide the contextual information necessary to implement the specification.

Mandatory

Unstated assumptions can cause independent implementers to interpret the same specification differently. Missing contextual information can also make otherwise precise requirements difficult to apply.

Explicit assumptions and context establish the environmental, organizational, architectural, operational, security, and technical conditions under which the specification is intended to be interpreted and implemented.

A conforming Submission demonstrates that:

1. Assumptions affecting interpretation or implementation are explicitly identified
2. Architectural context needed to understand the specification is provided
3. Environmental assumptions are described
4. Organizational or jurisdictional assumptions are identified
5. Operational assumptions are stated
6. Security assumptions affecting architectural behavior are identified
7. Dependencies on external specifications, services, models, or infrastructures are identified
8. Preconditions affecting the applicability of requirements are stated
9. Limitations resulting from an assumption can be determined
10. Assumptions are distinguishable from normative requirements
11. The supplied context is sufficient for independent implementation
12. Unstated implementation choices are not required to interpret normative behavior

An assumption does not override or weaken a mandatory requirement. If an assumption limits the applicability of a requirement, the relationship and justification must be stated explicitly.

Context should explain the conditions needed to interpret and implement the specification without prescribing implementation details that the RFP requires to remain technology neutral.
