Requirements Quick Notes, William L. Honig, Shingo Takada

William L Honig

A short introduction to requirements and their role in system development. Includes industry definition of requirements, overview of basic requirements process including numbering of requirements, ties to testing, and traceability. An introduction to requirements quality attributes (correct, unambiguous, etc.) Includes references to requirements process, numbering, and quality papers.

Requirements Metrics - Definitions Of A Working List Of Possible Metrics For Requirements Quality, William L. Honig Oct 2017

Requirements Metrics - Definitions Of A Working List Of Possible Metrics For Requirements Quality, William L. Honig

William L Honig

A work in progress to define a metrics set for requirements. Metrics are defined that apply to either the entire requirements set (requirements document as a whole) or individual atomic (or singular, individual) requirements statements. Requirements are identified with standard names and a identification scheme and include both subjective and objective measures. An example metric for the full set of requirements: Rd2 - Requirements Consistency, Is the set of atomic requirements internally consistent, with no contradictions, no duplication between individual requirements? An example of a metric for a single requirement: Ra4 - Requirement Verifiability, How adequately can this requirement be …

Atomic Requirements Quick Notes, William L. Honig, Shingo Takada Oct 2017

Atomic Requirements Quick Notes, William L. Honig, Shingo Takada

William L Honig

Working paper on atomic requirements for systems development and the importance of singular, cohesive, individual requirements statements. Covers possible definitions of atomic requirements, and their characteristics. Atomic requirements improve many parts of the development process from requirements to testing and contracting.

Applicability Of General Scenarios To The Architecture Tradeoff Analysis Method, Len Bass, Mark H. Klein, Gabriel A. Moreno Sep 2001

Applicability Of General Scenarios To The Architecture Tradeoff Analysis Method, Len Bass, Mark H. Klein, Gabriel A. Moreno

Gabriel A. Moreno

The SEI has been developing a list of scenarios to characterize quality attributes. The SEI has also been conducting Architecture Tradeoff Analysis Method (ATAM) evaluations. One output of an ATAM evaluation is a collection of scenarios that relate to quality attribute requirements for the specific system being evaluated. In this report, we compare the scenarios elicited from five ATAM evaluations with the scenarios used to characterize the quality attributes. This effort was designed to validate the coverage of the existing set of general scenarios and to analyze trends in the risks uncovered in ATAM reports.
