Matrix

H1: Multiple examples H2: Only software eng H3: Common, varies

Diagnosticity Analysis

Most Diagnostic Evidence

Evidence ID Why Diagnostic
SRC02-E01 Civil engineering predating formal schools by centuries discriminates between H2 (software only) and H1/H3 (multiple examples).

Least Diagnostic Evidence

Evidence ID Why Non-Diagnostic
SRC01-E01 As the known example from the query, it does not discriminate between hypotheses.

Outcome

Hypothesis supported: H1 — Multiple disciplines went through this phase, well-documented.

Hypotheses eliminated: H2 — Software engineering is not unique; civil engineering and knowledge engineering demonstrate the pattern.

Hypotheses inconclusive: H3 — Partially supported as refinement of H1; the varying formalization outcomes are relevant.
