## Abstract

In this paper, we propose a control charting procedure based on robust Hotelling’s T2. For that purpose, a new stopping rule will be introduced to improve the computational efficieny of data concentration process used in Phase I operation. A simu lation study will show the advantage of that robust approach compared to the classical one. A case study in spike production process in a Malaysian company will be reported.
