“…In recent decades, lean system is gaining a momentum across different industrial sectors. It has been originally started as Toyota production system which describes the manufacturing philosophy of Toyota Motor Corporation (Dombrowski & Malorny, 2014;Holweg, 2007;Womack & Jones, 2003). This lean system has been successfully extended to service industries, such as maintenance service, retail banking, airlines, restaurants, public sector, education, food, and hospitals (Burgess & Radnor, 2013;George, 2003;Pedersen & Huniche, 2011;Resta, Powell, Gaiardelli, & Dotti, 2015;Smith & Hawkins, 2004;Thirkell & Ashman, 2014;Zarei, Fakhrzad, & Jamali Paghaleh, 2011).…”
