| Summary: | This study is about the development of decision support instrument for selecting lean
tools and techniques based on the contingency factors to help Malaysian organizations
to select the right lean tools and techniques based on their context. Most of the prior
studies were found focusing on the selection lean tools but did not assess the critical
contingency factors that may influence the selection of lean tools and techniques.
Adding to that, there were no similar studies on the selection of lean tools and
techniques within the Malaysian context. The right tools and techniques to be used
may vary depending on several factors, therefore to keep away from unnecessary waste
and dissatisfaction, it would be better for organization to choose the right lean tools
and techniques that will fit with organization’s situation and give benefits to the
organization. A mixed-methods study exclusively focused on the development,
evaluation, and refinement of a decision support instrument or specifically known as
“Decision Aid for Lean Tools and Techniques Selection” (DEALS) was used. The
developed decision support instrument, which incorporates 10 most widely used lean
tools and techniques was emphasises the use of holistic processes which start from
diagnose their current state of waste until the guidance of selecting the appropriate lean
tools and techniques. Additionally, contingency factors were employed to include
multifaceted viewpoints and contexts in the development of DEALS, such as the
adeptness to acquire the commitment and support from the top management and the
advantages of implementing lean tools and techniques. The developed decision
support instrument includes two selection methods, namely (1) simple additive
weighting (SAW) for basic selection and (2) analytic hierarchy process (AHP) for
more advanced selection. Based on the evaluation results, all respondents (100%)
agreed on the usability, accuracy, and novelty of DEALS as well as the relevance and
validity of the selection and the clarity of the purpose of DEALS. The final results of validation testing also shows less than 5% errors when comparing final results of
DEALS with two established software which are Expert Choice 11 software and Super
Decision Software. By having this DEALS, it expected significantly benefit to
managers, practitioners, consultants, researchers, and academicians as a guidance
instrument in the selection of lean tools and techniques and generally to organization
to have knowledge workers. |
