Examples
For example (1), Scale-Qualifiers (*381) are one example of Generic terms: this could be a Generic-Standard (*150) – a template for a “User Reaction” definition.
User Reaction:
Scale: Probability that defined [People] will report defined [Faults]
within defined [Time Limits].
Then somewhere, just here locally, or in a more global Project Glossary, we define the Generic Terms
For example (2): ( and these could also be either Generic-Standards, or specific to the project. “….” Indicates a “list of more detail”, which we choose not to show here.
People: Defined: The Class of customer, {Customers (Default), Trial
Users, …}.
Faults: Defined: The Class of Faults, {Show Stoppers, Help Problems, … }.
Time Limits: Defined: Time from Fault occurred until report received and
logged by us. {n Hours, N Days, Same Day}.
• In the example (1) “defined [People]” and two other similar qualifiers in the Scale Specification, are Generic Terms. That Means, they need further definition.
• They are defined in example (2), and a set of known values for each is listed in the {Set Parenthesis}. Even this definition (2) is a Generic Term, because it needs further definition to pick the exact Class or time.
• One People Class (2), (“Customers (Default)” ) is identified as the “Default Value” (*447).
The use of these terms is illustrated by the example (3): using Scale Variables (*446)
User Reaction:
Scale: Probability that defined [People, Default: Customers] will report
defined [Faults] within defined [Time Limits].
Tolerable [Customers, Show Stoppers, 24-Hours] 90%
Goal [ People = Trial Users, Faults = Help, Time Limits = 1 hour] 99%
Wish [ Faults = Show Stoppers, Same Day] 95%
Notes
Note [Illustration 3].
• We have illustrated defining the Specific Terms by simply using Defined-Term Classes (“{Show Stoppers, Help Problems}”), and even doing so (3, Fail) in the same sequence (“People (Faults (Time Limits”)) in which the Generic Terms were specified, in the Scale specification (1 above).
• We also illustrated (3, Wish & Goal) the use of Explicit Parameters (example “Faults =“) for defining Specific Terms (example “Help”).
Reliability:
Type: Product-Value-Requirement.
Scale: Mean Time Between Failure from defined [Event Beginning] to
defined [Event Ending] for defined [System] under defined
[Circumstances].
Meter: defined [Test Circumstances {Development, Acceptance Test, Operation}] <specify or refer to test Procedure or protocol or
Standard>
Goal [<when, where, which circumstances>] <a Level such as
30,000 hours> ( <Source.>
Authority: <which Levels of management, or customer contract,
determine the Level?>
