Lanka Harness Company (Pvt) Ltd, founded by Rohan Pallewatte, makes impact sensors for airbags, where virtually no fault is tolerated and with defects set at one part per million (1 ppm) in theory.
Under the Six Sigma process 99.99966 percent of the output is expected to defect free or 3.4 defects are tolerated per million opportunities.
"But here is a situation where even zero defects are not tolerated," he told senior business executives at Sri Lanka's LBR-LBO CEO forum in Colombo.
"Just 1 ppm. At the impact the airbag must come out. It cannot fail."
