Identification of the Barriers in Implementation of Lean Principles in Iranian SMEs: Case Study Approach

摘要

The manufacturing sector is considered to be a cornerstone in the global economy through its influence on areas such as mining and construction in upstream and warehousing and transportation in downstream.

This paper aims to identify the main barriers in implementation of lean manufacturing principles in Iranian SMEs. In order to do so, case study approach was selected and 9 in-depth interviews were conducted in various industrial sectors such as electrical equipment, industrial machinery and automotive part supplier. As a result the main barriers were classified into four categories namely, lack of top management support, financial capability, lack of employee’s skill and expertise and organizational culture.
