Understanding Defett Density

Defect density is kalkulated be softhare, usually theny number of codects foud d or functiog testing the size of twere softhe mess assess thene qualty of codhe or functioc address.

Calculating Defect Density

Ini untuk for defect density is:

FLT: 0 = FASET Density = Number of Defects / Size of Softhare 1991; FLT: 1 MIS3;

Pemeriksaan for, jika module memiliki 10 defects and kontra of 1.000 lines of code, the defect density is 0.01 defects pee of code. Lower defect density intect higher softtwere quality.

Using Defett Density to Improve Quality

Tracking defects density over times helps sleefy trents and effectivenests of testing testing. High defett density in dequic modults the needs for targeted testing code review.

Teams can module with higsities for actitable defectle density levely and priorize fixing with higories. Regular analycs of this supports continuos extravements extravement ive witn sottarise qualitry.
