Fuzzy Developed Tool For Assessing Risk of Failure of Lean Implementation
This paper introduces a new tool to measure the risk of lean implementation failure inside enterprises. The tool is designed based on a proposed model that manipulated fuzzy logic to measure the risk of lean failure and is called LIFRAT (Lean Implementation Failure Risk Assessment Tool). LIFRAT takes input from users in the form of multiple indicators that measure different aspect of lean inside the enterprise. The indicators are categorized into four main categories: Managerial indicators, Functional indicators, Human factors indicators and External indicators. A sensitivity analysis was carried out to investigate different relations between the four main categories of lean indicators and the associated risk of failure. The developed tool was further demonstrated using four hypothetical cases of enterprises at four different stages of business life cycle. Results showed the ability to quantify the risk of lean implementation failure. In addition, they showed that the risk of failure to implement lean system depends on the life cycle stage of the enterprise as well as the different weights allocated for the previous mentioned indicators. This research is an extra step to help managers in successful migration/implementation of lean concepts and tools via reducing the risk of failure of such process.
