The survival of any organization depends upon its competitive edge. Even though Lean is one of the most powerful quality improvement methodologies, nearly two-thirds of the Lean implementations results in failures and less than one-fifth of those implemented have sustained results. One of the most significant tasks of top management is to identify, understand and deploy the significant Lean pra...

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....

To the editor: We read with interest the article by White et al., “Using Lean-Based Systems Engineering to Increase Capacity in the Emergency Department,” in which the authors conclude that Lean could improve emergency department (ED) throughput and capacity. A number of other studies have also suggested that Lean is beneficial in addressing the problem of ED wait times. As in White et al., the...

In the last few decades, lean techniques have been developed for removing with waste in manufacturing. More recently, lean is used outside the manufacturing context as well. This article focuses on using lean thinking for reducing waste in administrative services, i.e., business services with information as input and output. This article delivers three innovations in this field: 1) a lean appro...

in this study, production, reproduction, managerial, and economic parameters obtained from data recorded for lori-bakhtiari flock of sheep (500 heads of breeding ewe) stationed at the sheep's breeding station, were employed to determine the relative economic values of and breeding objectives for an annual cycle of production, in village system in this breed of sheep. economic value for a t...

Successes in lean manufacture have led researchers and practitioners to consider extending ‘lean’ to different parts of the engineering enterprise, including product and process development (PPD). Lean product development (PD) has been understood to mean lean manufacture applied to PD, while the roots of lean PD – just like lean manufacture go back to Toyota. This paper presents the methodology...
