Struct PutnamModel 

Source 
pub struct PutnamModel {
    pub ck: f64,
    pub d0: f64,
}
Expand description

Putnam/SLIM model.

Software Equation: Size = Ck × E^(1/3) × T^(4/3) Combined with D0 = E / T³: T = (Size / (Ck × D0^(1/3)))^(3/7) [years] E = D0 × T³ [person-years]

Fields§

§ck: f64

Technology/productivity constant Ck. Typical: 2000 (poor), 8000 (good), 11000 (excellent).

§d0: f64

Manpower buildup index D0 = Effort / Time³. Typical: 8 (new/many interfaces), 15 (new standalone), 27 (rebuild).
