The Impact

Each year our Clinical and Translational Science Award pilot projects program awards approximately $500,000 in translational pilot funding to advance health in South Texas. We identified needs to improve the timeliness, transparency, and efficiency of the review process by surveying applicants. Lean six sigma methodologies, following a “Define, Measure, Analyze, Improve, Control” approach, were used to streamline the pilot project application and review by identifying and removing bottlenecks from process flows. We evaluated the impact of our reorganized review process by surveying applicants and reviewers. Process mapping identified pilot project review as the main source of delay, leading to the implementation of a study section-style review mechanism. After one cycle, 90.3% of pilot applicants and 100% of reviewers were highly satisfied with the new processes and time to award notice was reduced by 2 months. All reviewers familiar with both review processes preferred the study section. We demonstrated how lean six sigma, a methodology not commonly applied in research administration, can be used to evaluate processes in translational science in academic health centers. Through our efforts, we were able to improve timeliness, transparency, and efficiency of the review process.

Purpose The purpose of this paper is to compare the impact of lean six sigma (LSS) implementation carried out in a pharmaceutical unit on the profitability of outpatient and inpatient care before and during the Covid-19 pandemic. Design/method/approach The data were analyzed descriptively to see the development patterns in four periods: before implementation, during the implementation before the pandemic, during the pandemic and during the enforcement of new normal, in general, and by the length of stay (LOS). Findings The inventory purchase in the pharmaceutical unit dramatically decreased after implementation even during the pandemic and new normal wherein the pre-pandemic it decreased by 27%, during the pandemic 29% and in the new normal 37% compared to pre-LSS. The hospital deficit decreased after implementation before the pandemic by 26% and during the pandemic by 10% from the pre-LSS time. However, during the new normal, the deficit increased by 29%, indicating a diminished effect of LSS on the hospital profits. Research limitations/implications This research raised the possible implication that the implementation of LSS needed to be carried out in the entire hospital to have a large effect, especially on the inpatient care and long-term care installations. Originality/value This research provided empirical evidence regarding the effect of the Covid-19 pandemic on the ability of LSS at the unit level to provide efficiency at the unit level and the entire hospital at various levels of LOS.

Purpose This paper aims to contribute to a developing literature on continuous improvement (CI), enabled by Lean Six Sigma (LSS), in higher education institutions (HEIs). It reports on the key learning points arising from the initial steps taken by an Irish university on its CI journey. Design/methodology/approach A case study strategy was adopted following a participatory research approach. This approach supports reflexivity and also provides access to all relevant documentation and staff within the case university. Thematic analysis was supported by data reduction and display techniques. Findings The introduction of a LSS approach rather than a reliance on lean alone introduced a structured methodology (DMAIC) that supported simplification of a number of administrative processes. A number of specific improvements were achieved including: Cycle time and cost reduction; customer or employee satisfaction; and rework and error reduction. The findings support the importance of the Readiness Factors as identified by Antony (2014), with particular insight into the role of senior and middle management, the impact of training and deployment of expertise. Research limitations/implications This paper is based on an ongoing, longitudinal, empirical study of a single case study in Ireland. Originality/value This paper tracks the development of CI in a HEI in a longitudinal manner and adds to the emerging the literature in this area. The paper evaluates the role of management at various levels, analyses the use of LSS tools and techniques and evaluated the role of training and capacity building. Implications for Management are shared including: design and role of training programmes, role of champions at various organisational levels, including key functional areas and sustaining momentum.

Purpose The purpose of this paper is to use a practical case study approach to demonstrate the power to use lean Six Sigma (LSS) to improve service process in a higher education institution (HEI). The paper also illustrated the barriers and challenges met and lessons learnt for the LSS adoption in this HEI. Design/methodology/approach Prior to the study, extensive literature review was conducted to understand various aspects of LSS in HE industry. The authors use a single descriptive case study as methodology to explain how DMAIC was applied within a HEI environment. Findings In this LSS case study, the team found HEI service process contains a large human behavior component, which dramatically increases the unpredictability of the entire service delivery process and increases the complexity of the process and the ability of the improvement team to identify the root cause. This case study demonstrates the numerous challenges will occur in working with the intangible factors that are both hard to recognize, quantify and rarely tracked by organization. Practical implications During the research, the pre-award service process was studied, data were recorded and various statistical tool and techniques were used to discover and resolve the root cause. The lessons learnt of the LSS adoption in this service process in HEI and the problems encountered were all recorded in this study, which will be helpful for future research in HEI industry. Originality/value From the literature review, LSS has been widely adopted in manufacturing industry, increased adoption in service, but there has been limited academic research about the implementation in nonprofit, service sectors, particular to higher education industry. The major benefit of implementation LSS in both manufacturing and service is considerable improvement to the bottom line. However, in this HEI case study, it has opened up the direction to implement LSS to better serve your customer as ultimate mission instead of financial gains.
