Function average_maturity_level 

pub fn average_maturity_level(scores: &[u8]) -> Option<f64>

The arithmetic mean across a set of per-dimension maturity levels — the more flattering composite the chapter explicitly warns against using as the overall score. Kept here so callers can compute it alongside minimum_maturity_level and see the gap between the two.

Arguments

• scores — one maturity level per dimension assessed.

Returns

The mean level as an f64, or None if scores is empty.

Examples

use software_engineering::maturity_model::average_maturity_level;

let average = average_maturity_level(&[4, 4, 4, 1, 4]).unwrap();
assert!((average - 3.4).abs() < 1e-9);
assert_eq!(average_maturity_level(&[]), None);
