R0021/2026-03-25/Q005 — ACH Matrix¶
Matrix¶
| H1: Multiple examples | H2: Only software eng | H3: Common, varies | |
|---|---|---|---|
| SRC01-E01: NATO "need not reality" | ++ | N/A | ++ |
| SRC02-E01: Civil engineering pre-formal schools | ++ | -- | ++ |
| SRC03-E01: Knowledge engineering "little formal process" | ++ | -- | ++ |
Legend: ++ Strongly supports · + Supports · -- Strongly contradicts · - Contradicts · N/A Not applicable
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.
