Combining lean tools application in kaizen: a field study on the printing industry

Abstract

PurposeThe purpose of this paper is to highlight the lessons learned from two kaizen events for productivity improvement in a printing company. The paper suggests how to organize lean tools to improve productivity through the use of organized kaizen events in the printing industry to meet defined targets.Design/methodology/approachThis paper is based on a field study involving participant observations. The relationships among the three specific tools, line balancing, standardized work and standardized layout that are used in a kaizen event of a printing factory, are examined.FindingsApplication of a mix of lean tools resulted in significant productivity improvements of 10-30 percent in the assembly area of the printing company. Based on the outcomes of the lean tools that are applied in various work areas, the best combinations of lean tools are identified and several key considerations are discussed.Practical implicationsThis paper shows that a combined set of lean tools such as line balancing, standardized work and standardized layout can be applied to improve productivity in the printing operations, which is identifiable with a mix of processes that are both labor intensive and equipment flexible.Originality/valueThe paper fills the literature gap on the use of specific lean tools: line balancing, standardized work and standardized layout in the printing industry. The findings from this research can be applied to other assembly systems that are similar to the printing industry.
