Closes #1264

Resolved three leftover TODO comments in introduction.tex:

  • Added examples of formal definitions of functional quality (defect density, code coverage).
  • Added a reference to ISO/IEC 25010:2023 to support the claim about maintainability quantification.
  • Added a reference to Leveson (2011) regarding safety-critical domains.

PDF builds successfully locally without LaTeX errors.

Summary by CodeRabbit

  • Documentation
    • Expanded the introduction with clearer explanations of measurable functional-quality metrics (e.g., defect density and test coverage).
    • Refined the discussion contrasting functional quality with maintainability.
    • Added bibliography entries for ISO/IEC 25010:2023 and Engineering a Safer World.

Qualify these metrics as indicators, not measures of correctness.

Defect density and code coverage are quantifiable, but neither directly establishes functional correctness. Please describe them as indicators of functional quality and add supporting citations for the metric claims.

Proposed wording
- metrics such as defect density measured per 
- thousand lines of code (KLOC), code coverage percentages, or pass/fail rates 
- of functional test suites provide clear, quantifiable measures of functional correctness. 
+ metrics such as defect density per thousand lines of code (KLOC), code coverage,

Use a source that supports the quantification claim
ISO/IEC 25010 defines the product quality model, but it doesn’t substantiate the comparison that maintainability is “less straightforward to formally specify or quantify.” Narrow the sentence to what the standard states, or add a source that explicitly contrasts maintainability with more directly measurable qualities.

Also, in certain applications it appears less important than
functional correctness, although in the business domain it is recognized as an
essential property.

Change “business domain” to “safety-critical systems”
Leveson’s book is about engineering safer systems and safety-critical applications, so the current wording overstates what the citation supports. Reword this sentence to match that context, or cite a source that discusses maintainability in the business domain.
