Control charts for monitoring process with time trend

2025-04-17T11:39:14-03:00

Purpose: Statistical process monitoring has been a relevant practice incorporated into quality management systems. In a controlled process, the variabilities of statistical parameter estimates are expected to fluctuate within a pattern over time. Whenever this pattern is not identified, the root causes must be identified, and the necessary actions should be taken. However, there are situations where special causes are present but not practically significant. Recent studies on profile monitoring have tailored solutions for efficiently detecting trends and seasonality in high-capability processes. This paper proposes using profile curves and statistical modelling based on the location control chart approach.

Design/methodology/approach: Our research was carried out using decision-prescriptive models and the Design Science Research approach to identify solutions for real and complex problems. Additionally, the modeling and simulation method was utilized to assist in developing, analyzing, and testing the model, which was classified as an artifact.

Findings: The modeling results clearly demonstrate that utilizing location control charts and modified graphs is essential in defining equipment adjustments. This approach guarantees the minimum acceptable capacity and maximizes the use of productive resources.

Originality: This study provides novel opportunities for developing and implementing control charts in systems that do not conform to the principles of randomness but rather display intricate temporal patterns. This is particularly relevant in the context of Quality 4.0, where real-time data collection is pervasive.

Enhancing firm performance with supply chain risk management and supply chain resilience

2025-04-09T21:07:21-03:00

Goal: This study aims to investigate how supply chain risk management (SCRM) impacts firm performance (FP) in Karawo MSMEs, while also considering the mediating role of supply chain resilience (SCR) and the moderating influence of supply chain digitalization (SCD).

Design/Methodology/Approach: This study develops a theoretical framework to analyze the influence of supply chain risk management on financial performance, based on resource-based theory (RBT). The analysis involved data collected from 195 micro, small, and medium enterprises in Gorontalo province, utilizing Partial Least Squares Structural Equation Modeling (PLS-SEM) to assess the theoretical hypothesis.

Results: The findings indicate that demand risk management (DRM) and regulatory risk management (RRM) substantially enhance FP and systemic capital requirements (SCR). Furthermore, SCR serves as an intermediary in the relationship between SCRM and FP. This study also determined that SCD does not exert a beneficial moderating influence on the connection between SCRM and SCR.

Practical implications: This study assists MSMEs in enhancing performance via supply chain resilience. This study further on prior research in the SCM field by establishing a theoretical framework that connects DRM and RRM to risk management.

Originality/Value: This research elucidates the impacts of DRM and RRM that influence SCR, grounded in RBT. Secondly, SCR is presented as an intermediary phase connecting SCRM and FP, elucidating the internal mechanism linking the two. This study further examines the role of the SCD component in the link between SCRM and SCR.

Remote work management

2025-06-22T11:10:10-03:00

Goal: The study took research dealing with remote work management and how it is solved, taking into account efficiency of leadership, communication strategies, use of technological tools, and their impact on team performance and work-life balance.

Design/methodology/approach: The research followed a quantitative design and comprised including survey tools on questionnaire, and Structural Equation Modelling (SEM).

Results: The results show that presence of effective leadership leads to a doubling of virtual team performance with a cross-path (path coefficient = 0.45, P<0.001). Remote work tools alone could enhance productivity (path coefficient = 0.40, P<0.001), while proper communication is another way to solve some of remote work challenges (path coefficient = -0.35, P<0.001). The main result of present study was that flexible work arrangements lead to a better work-life balance (path coefficient = 0.50, P<0.001) and employee engagement is a mediator between leadership and productivity (path coefficient = 0.55, P<0.001).

Limitations of the investigation: Representativeness of sample may be limited and there may be differences in remote work management practices in different industries and companies.

Practical implications: The findings discussed may be a tool for organization to review their methods and bring remote teamwork to a more successful stage through improved leadership, use of technology, and communication strategies for better productivity and well-being of employees.

Originality/value: This research aids managers in coping with off-site work. That is done by employing theories and then checking them empirically which are then used in discussion for remote work management moments and employee satisfaction issues.
