BACKGROUND The demand for cataract surgery is rising, calling for pathways that have good access and are cost-effective. Lean thinking is a management strategy, aimed at improving quality while reducing costs. Lean production processes are designed to identify gaps between expected and actual performance. AIM To analyse the efficacy and efficiency of a lean cataract pathway. METHODS Lean ca...

This article compares the techniques developed for lean construction with those developed for lean manufacturing. Lean manufacturing and lean construction techniques share many common elements despite the obvious differences in their assembly environments and processes. Manufacturing plants and construction sites are different in many ways that might explain why lean production theories and pra...

In this paper we introduce the notion of a suitable semantics which is very similar to the notion of a well behaved semantics. While well-behaved semantics ask for the relevance property, suitable semantics ask for ratio-nality. We argue that suitable semantics can be more appropiated than well-behaved semantics in some cases. We also introduce CSC, which is a suitable semantics deened via a co...

disconnects and defects in care – such as duplication, poor integration between services or avoidable adverse events – are costly to the health system and potentially harmful to patients and families. for patients living with multiple chronic conditions, such disconnects can be particularly detrimental. lean is an approach to optimizing value by reducing waste (eg, duplication and defects) and ...

A subset S of a topological group G is said to be a suitable set if (a) it has the discrete topology, (b) it is a closed subset of G \ {l}, and (c) the subgroup generated by S is dense in G. K.H. Hoffmann and S.A. Morris proved that every locally compact group has a suitable set. In this paper it is proved that every metrizable topological group and every countable Hausdorff topological group h...

Lean practices and principles build on a half-century of successive initiatives aimed at transforming social and technical systems in organizations. While they are seen as central to the revitalization of the U.S. aerospace industry, there is great variation in the degree to which lean initiatives emphasize just technical/manufacturing systems versus additional social and enterprise dimensions....

S ystems engineering is regarded as an established sound practice but not always delivered effectively. Sixty-two recent successful space launches indicate that mission assurance can be practiced well. At the same time, recent U.S. Government Accountability Office (GAO) and NASA studies of space systems [1, 2, 3, 4] document notorious major budget and schedule overruns, some exceeding 100 perce...

Unsustainable increases in health care costs mandate efforts at cost reduction. Such efforts necessitate enhanced productivity, especially given the specter of an aging population afflicted by a burgeoning chronic disease burden. Productivity is less a choice than an imperative forced upon hospitals and health systems as they attempt to address the competing requirements of diminished resources...
