Detailing

The designer uses a set of such design Goals, including Budget-Targets, as well as Constraint information, to decide if they have found good enough Design-Ideas to satisfy the Performance-Requirements, within the Constraints specified.

Type

Requirement Level, Target


Examples

Tolerable [End Next Year] 30. “a Design-Constraint”
Goal [Within 6 Months After Launch] 60. “a Design-Target”

''The target is not merely the “60” but includes the [Qualifier] information.

In addition, the Tolerable and Goal specification both give critical information about the Priority of the target (design survival point (Fail) and success point (Goal)).''

Usage 2. It is normal Engineering practice for a designer to apply a Performance-Target Level with a built in Safety-Factor, as the Level they try to design for; for example two times the nominal specified Level might be applied as the Safety-Factor target. The Value-Decision Process makes use of this Safety-Factor Concept.

Usage 3. A Design-Target may be specified using one of the target specification Parameters {Goal, Stretch, Wish}. This applies to performance and Budget-Targets.

Example:
Stretch [Next Release] 66.5 hours.
