This document describes a quality improvement project to reduce the time users take to exit the Faculty of Engineering's motorcycle parking area. The team first defined and measured the problem, finding 86% defects and high variability. Analysis showed the main causes were forgetting locations and lack of a standardized route. The team improved the area by classifying parking spots with numbers and letters and creating a clear flow direction. After implementing these changes, defects reduced to 13% with much lower variability. User satisfaction increased from 33% to 84%.

the defects
Normal Time = 77 s
Allowances (Talking, Preparing
things, etc.) = 12.99%
Standard Time = Normal Time +
(Normal Time x Allowance) = 77 + (77 x
12.99%) = 87 s
Data which is higher than 87 s
= DEFECTS!

DPMO = total defects/ total opportunities x
