Descriptions (what I know)
Str#58. "Describe Attributes with a Template" Strategy
- Describe each attribute, using a template as your
guide.
-
- description
- legal values (range; limit; enumeration of
values)
- unit of measure
- data type
- tolerance
- required (yes or no)
- get/set constraints
- how to get a default value from another source, in
the event a custom value is not known
- applicable states (for state-dependent
attributes)
- traceability codes (to a requesting document, if
any).
Str#59. "Describe Real-Time Attributes" Strategy
- For real-time, categorize each attribute as: state,
state-dependent, or state-independent.
- Examples:
-
- state attributes: status, operational state
- state-dependent attributes: value, reading
- state-independent attributes: name, serial
number.
