Background: Many organizations have adopted Lean tools to improve healthcare, but few studies adequately evaluate the effectiveness of Lean tools, such as Rapid Process Improvement Workshops (RPIWs).Objective: To evaluate the effectiveness of RPIWs conducted in surgical services at two hospital sites from economic and statistical perspectives.Methods: Retrospective data over three years from the two interventions sites were used for a cost-benefit analysis in the form of Return on Investment (ROI). The Interrupted Time Series (ITS) method was used to analyze the trends of selected process measures such as surgical volumes, overtime, and sick time hours during intervention and post-intervention periods at the two sites. Also, comparable data from two control sites were used to statistically compare the trends of some of the process measures between the intervention and control sites.Results: The cumulative effects of the six RPIWs performed at each site were examined. The results did not produce any evidence to indicate that the outcomes justify the investments. The ITS analysis revealed no indication of systematic and sustained change in the pattern of process measures at the intervention sites as a result of RPIWs. Nor did they provide significant or conclusive evidence when comparing the process measures between the intervention and control sites.Conclusions: This study identifies some of the difficulties of empirically calculating the ROI of RPIWs, and provides evidence that any realized benefits due to RPIWs implemented in two hospitals were not worth the investment. Such a result may lead us to challenge any unfounded claims of high monetary benefits from Lean tools or similar quality improvement initiatives.

This article is derived from a qualitative multicase study with two settings that explored the way decisions are made in two IT organizations regarding process improvement initiatives by using face-to-face semi-structured interviews with 20 IT process owners and managers. The two participating organizations are a healthcare insurance company and a manufacturer of electronic interconnects. The study sought to uncover (a) how IT process improvements are prioritized and how approvals are attained, (b) how senior leadership is involved in decision making, (c) how security and risk are considered, (d) if and how formal process improvement methodologies are used, (e) if and how estimated and actual cost benefit analysis are conducted associated with decisions, and (f) how alignment with organizational goals is attained. The topic of IT governance was narrowed to explore the perspective of IT process owners and process managers, and their approaches and methodologies used with IT process improvement initiatives. The study found that pre-decision stages take place in IT investment decision making, and that process owners and process managers, participants other than senior leadership, and executive level decision makers are involved in these pre-decision stages and may be involved in the final decision stages.

Decision making concerning the allocation of and distribution of funds in highly automated or computerized offices is often biased by the orientation of the decision maker, and the previous cost benefit analysis of the “system” implementation study. In such an environment, costs are often allocated to hardware or software enhancements, without regard to other factors potentially influencing worker productivity or efficiency. The present study addressed the problem of developing a methodology that would allow for the most expansive listing of factors influencing worker productivity or efficiency. The method used allowed for the greatest amount of input from subject matter experts as well as from system users. The data gathering method is described that facilitated the development of a questionnaire method implemented in a work environment of a major inventory and control system office. The data analysis indicates the functionality of the method, and its usability in a vast number of environments.

AbstractThis paper raises two main questions. The first concerns the current idea that punishment – conceived as the loss of liberty – has an effect in preventing unlawful behaviour. It can in fact be shown that, in general, sanctions have a poor individual preventive effect. As to general prevention, punishment may be expected to have a deterrent effect when the unlawful behaviour is the result of a rational decision, that is, a decision based on a cost–benefit analysis. However, a wide variety of factors, from group support to situational and systemic factors, may very well counteract the threatening effect of the sanction. The second question concerns the feasibility of non-stigmatizing ways to cope with crime. The few examples borrowed from legal anthropology seem to indicate that viable alternatives exist. But the transfer of a non-Western, indigenous problem-solving process to culturally different contexts is problematic and should be carried out with extreme caution.

Research Analysis

The administration of an inventory implies saying how much material is needed and when to place orders, receive, store and keep the record, since the main objective is to keep costs low and keep enough finished products for sales. The inventory represents one of the most important investments of the companies in relation to the rest of their assets, since they are fundamental for the sales and indispensable for the optimization of the utilities. The research "Analysis of inventory control in the Muelles Melecio microenterprise" is intended to analyze the management of inventories in the Mulles Melecio microenterprise. To know the procedures used by the organization, the application of the instrument is carried out, consisting of questions related to inventory management and comprehensive cost-benefit analysis. and finally the descriptive analysis of inventory control in the microenterprise. The type of research that follows this project is non-experimental and descriptive. The design that will be used corresponds to the transectional, consisting of collecting data in a single moment, in a single time. Its purpose is to obtain an analysis of the management and control of the inventory at the Muelles Melecio microenterprise.

An inspection of the time-plot of monthly Prime Motor Spirit (PMS) distribution in Nigeria from 2009 to 2015 reveals an abrupt jump in January 2013 with the series continuing at that level till 2015. Clearly the trend of the series was interrupted in January 2013 and it is believed that this perturbation was due to the deregulation of the downstream sector of the crude oil industry.  A t-test comparison of the pre- and the post-intervention means is highly significant (p < 0.0001) indicating the impact of the intervention. A model of the ARIMA family was to be fitted to the pre-intervention data which were observed to have a downward trend and be non-stationary. Differencing once rendered it stationary. An adequate ARIMA(2,1,0) model was fitted to the original pre-intervention series. Post-intervention forecasts were obtained on the basis of this model. These forecasts were subtracted from their respective post-intervention counterpart observations. These differences were modelled to obtain the transfer function of the intervention. The resultant intervention model closely fits the post-intervention data and may be used to explain and control the situation.

We investigate game-theory based decisions on vaccination uptake and its effects on the spread of an epidemic with nonlinear incidence rate. It is assumed that each individual’s decision approximates his/her best response (called smoothed best response) in that this person chooses to take the vaccine based on its cost-benefit analysis. The basic reproduction number of the resultant epidemic model is calculated and used to characterize the existence and stability of the disease-free and endemic equilibria of the model. The effects on the spread and control of the epidemic are revealed in terms of the sensitivity of the response to changes in costs and benefits, in the “cost” of the vaccination, and in the proportion of susceptible individuals who are faced with the decision of whether or not to be vaccinated per unit time. The effects of the best response decision rule are also analyzed and compared to those of the smoothed best response. Our study shows that, when there is a perceived cost to take the vaccine, the smoothed best response is more effective in controlling the epidemic. However, when this cost is 0, the best response is the more efficient control.
