SUSTAINING DAILY MANAGEMENT WITH GEMBA WALKS: A SCHEDULING MODEL

At an academic tertiary care medical center, there are 110 Operational Excellence teams across 4 campuses. Every weekday, 10 GEMBA walks occur with the 11^th on Wednesdays. The expanding program has made daily leadership visits to all KPIs challenging. As a result, consideration of reduced gemba walks to departments who have met specific maturity/performance criteria.

The scope of the eight-week pilot consisted of 13 pre-identified teams that have weekly workflows. The teams must have met a baseline level of performance. Performance was scored for 9 variables measuring engagement, PDSA, use …

Discrete Information Object Analysis Of Primary Flight Display Clutter, Kenneth Ward

National Training Aircraft Symposium (NTAS)

Modern aircraft utilize digital display screens to provide critical flight and system status information to pilots. As computing power has increased, the number of data sources and information presented has also increased, with the goal of increasing situational awareness. However, the display can become cluttered with extraneous or irrelevant information, to the detriment of pilot cognitive workload. Pilot perceptions of clutter vary with flight experience, introducing unique considerations in the flight training environment, given the experience difference between instructors and students. Researchers have studied the problem, identifying both the number of visual objects and information density as predictors of perception …

Metamorphic Testing Of Navigation Software: A Pilot Study With Google Maps, Joshua Brown, Zhiquan Zhou, Yang-Wai Chow

Faculty of Engineering and Information Sciences - Papers: Part B

Millions of people use navigation software every day to commute and travel. In addition, many systems rely upon the correctness of navigation software to function, ranging from directions applications to self-driving machinery. Navigation software is difficult to test because it is hard or very expensive to evaluate its output. This difficulty is generally known as the oracle problem, a fundamental challenge in software testing. In this study, we propose a metamorphic testing strategy to alleviate the oracle problem in testing navigation software, and conduct a case study by testing the Google Maps mobile app, its web service API, and its …
