However, very few studies highlight the prevalence of such practices in the restaurant industry. The purpose of this study is to highlight lean and green programs' implementation observed within smaller organizations in the restaurant industry of Northeastern Pennsylvania. Why small businesses? an excellent opportunity to conduct system-wide research large numbers of homogenous firms (Rigg & Bracker, 1986) Hold a relatively small share of the market, Fewer than 500 employees Small businesses report 20-30% cost savings by making energy saving moves….
