“…The delays in starting the first case in the baseline period was 49 of 182 opportunities, and after improvements were made, the delays declined to 10 of 182 opportunities. The cancellations in the baseline period were 92 of 341 opportunities, and after the improvements were made, the cancellations declined to 12 of 421 opportunities 11 . Another study using Six Sigma techniques made multiple suggestions to improve operating room efficiency and LOS for surgical patients 2 .…”

“…5 Six Sigma and Lean Six Sigma can be excellent ways to solve many large-scale complex problems, give greater value and satisfaction to patients and other customers, and increase the productivity and the morale of the employees without destructive cost cutting or decreasing quality. 11,16 Six Sigma does not necessarily have to be the only quality improvement methodology in a hospital, but there can be several complementary systems used in an institution to solve different issues. 8,17 The following are examples of the use of Six Sigma and Lean Six Sigma to improve hospital operations.…”

“…The considerable amount of training and the time for many Six Sigma projects are additional problems 10 . Furthermore, the overall quality of most hospital operations is not at the level of Six Sigma, which is the goal of many manufacturing operations, but according to a 2011 article, they are at 3 to 4 Sigma 11 . A 2005 article indicated that there was “a sigma level of 1.0 in the use of beta blockers to treat high blood pressure and other cardiac problems, a sigma level of 2.0 in treating depression, a sigma level of 4.0 in treating injuries, and a sigma level of 3.0 in antibiotic use.” 9 Such low levels are not confined to health care.…”

For existing goods or services, Six Sigma uses the steps of DMAIC and the statistical analysis of data to decrease variation and errors, improve the value of an organization's outputs to the customers, and increase the profitability of the organization. In health care, in view of the training required and other issues, Six Sigma is best used for large complex problems, although it has also been applied successfully to smaller issues. Many examples of the use of Six Sigma and Lean Six Sigma in health care are reviewed.

“…In the context of the service industry, DMAIC methodology can be utilized to manage customers' dissatisfaction within the business process as certain issues are identified, variables affecting process are quantified, sources of the problems are analyzed, improvement is de-signed and implemented, variables are monitored until the expected sigma level is attained, and customer satisfaction is optimized (Abdul and Purwatmini, 2018). Implementation of this method in a healthcare service company was reported to generate significant cost savings and improvement at the sigma level (Rohini and Mallikarjun, 2011). Large numbers of successful Six Sigma projects in the hospitality industry were reported that demonstrated improvement in productivity, menu redesign, resort concierge, e-mail marketing, waiting for time, billing error, occupancy rate, and sales (Chakraborty and Tan, 2012).…”

The DMAIC (Define, Measurement Analyze, Improve, Control) methodology of Six Sigma has been widely recognized as a breakthrough process improvement strategy for application among human resources that offers an impressive reduction in defects or errors in many business processes. Even though Six Sigma’s DMAIC was predominantly applied in the manufacturing industry, recent studies have revealed that it has been implemented effectively in the service industry as well. This article aims to explore the benefits and the fundamental challenges of DMAIC implementation as a student’s course project in five Indonesian service companies. An exploratory study was conducted to provide a clear understanding of DMAIC method implementation in service companies. A similar challenge, the lack of openness of the company, was found across cases. Several enhancements in company performance were identified, including improved customer satisfaction, reduction in delivery errors, and shorter waiting time. This research also highlighted the usage of some non-statistical tools and techniques that effectively contribute to each phase of the DMAIC method. Lastly, all five companies reported that these improvement projects offer positive benefits, including increased revenue and cost reduction.
