Rigor enhances understandability, improves reliability, facilitates assessment, and controls cost

Engineering = sequence of well-defined, precisely-stated, sound steps, which follow method or apply technique based on some combination of
- theoretical results derived from formal model
- empirical adjustments for unmodeled phenomenon
- rules of thumb based on experience
