Extract

Sackman et al. found: ratio of initial coding time between best and worst programmers was about 20:1; debugging times over 25:1; program size 5:1; program execution speed about 10:1. No relationship between experience and code quality or productivity was found.

Relevance to Hypotheses

Hypothesis	Relationship	Strength
H1	Supports	Confirms the Sackman portion of the claim
H2	Supports	Confirms the Sackman portion
H3	Contradicts	Large variation is confirmed

Context

The study's original purpose was comparing online vs. offline programming. The individual variation finding was a secondary but more impactful result.
