Ambulatory cancer centers face fluctuating patient demand and deploy specialized personnel who have variable availability. This undermines operational stability through misalignment of re-sources to patient needs, resulting in overscheduled clinics, high rebooking rates, budget deficits, and wait times exceeding provincial targets. We describe how deploying a Learning Health System framework led to operational improvements within the entire ambulatory center. Known methods of value stream mapping, operations research and statistical process control were applied to achieve organizational high performance that is data-informed, agile and adaptive. Caseload management by disease site emerged as an essential construct that incorporates disease site teams into adaptive, reliable care units, clinically and operationally. This supported clus-tering interdisciplinary teams around groups of patients with similar attributes, while allowing for quarterly recalibration. Systematic efforts were made in the negotiation required to im-plement changes that impacted physicians, nurses, clerks, and administrators. Feedback mecha-nisms were created with learnings curated and disseminated by a core team. The change aligned financial expenditures to the regional demand for specialized services and smoothed clinical operations across 5 weekdays and 2 centers. The impact was predictable, optimized expenditures, increased efficiencies across human and physical resource deployment and improved disease site collaboration in patient care.

Like many other countries, the presence of wasteful activities is very common in Kazakhstan’s construction industry. This severely affects the productivity of construction processes. Lean methodology maximizes the value of a process by minimizing wasteful or non-value adding (NVA) activities. This study aims to explore and quantify the impact NVA items on construction productivity. Several observations were made for construction processes in Astana, Kazakhstan to investigate and quantify various types of wasteful activities. Moreover, a survey was conducted to examine the general understanding of wasteful activities and Lean methods within the construction industry in Kazakhstan. In terms of wasteful activities, a similarity was found between the observed construction processes and survey results. Furthermore, apart from the commonly found seven types of wasteful activities, some other sources of waste, such as “preparation” and “break”, were found from the observations. Finally, wasteful activities were mapped with commonly used Lean tools, as found in the literature, so that productivity can be improved by minimizing NVA activities. From the mapping and the survey results, value stream mapping (VSM) was found to be the most effective Lean tool, since it facilitates increased visualization.

Purpose Value stream mapping (VSM) is very common in the manufacturing industry to enhance transparency and support improvements within the production process. The purpose of this paper is to evaluate the current status of the method from the user’s point of view and addresses its future sustainability in the context of the ongoing digitalization. Design/methodology/approach An empirical survey with 170 participants from different branches was conducted. The web-based questionnaire covers the topics Lean Management, respectively, VSM, Industry 4.0, the integration of both approaches as well as a possible need for action to modify the VSM. Results are analyzed in a quantitative way. Findings Benefits and shortcomings of VSM are already confirmed by previous publications. The serious challenge is the lack of flexibility of the method. In general users appreciate a combination of Lean methods and solutions of Industry 4.0. Moreover 92 percent of the participating experts request further development of the VSM using digitalization to compensate weaknesses. Research limitations/implications The findings are based only on Lean expert’s opinion. Over 95 percent of the participants are from Europe however most of them are from Germany. Although the results are adequate an international expansion of the survey would be advisable in order to distinguish local differences and similarities. In future work researchers need to further develop VSM to overcome the identified gaps. Practical implications Results of the study indicate the viewpoint of experts within different branches. This enables users to undertake a self-assessment regarding their own VSM-estimation. Originality/value This paper provides a current evaluation of the VSM from an exploratory perspective. The impact of global trends and new opportunities facilitated by digitalization are considered. Shortcomings and fields of actions become clear. Based on that necessity further research activities can be designed.

RESUMO: O Mapeamento de Fluxo de Valor (MFV) resgata a transparência dos processos à gerência de produção, possibilitando a eliminação das atividades que não agregam valor e otimiza a conversão. O artigo aplica o MFV ao processo de execução de alvenaria de vedação e identifica quais são as perdas e falhas no processo. A pesquisa realizada em uma empresa construtora goiana é classificada como estudo de caso, com abordagens qualitativas e quantitativas. Foram caracterizadas as atividades de fluxo e elaborou-se um MFV atual e futuro do processo produtivo de alvenaria convencional utilizando blocos de concreto sem função estrutural em um edifício residencial. Como resultado foi possível caracterizar as atividades e quantificar o impacto das atividades improdutivas e auxiliares do processo. Como principal contribuição foi possível identificar quais são as perdas e falhas no processo, propondo melhorias, a fim de reduzir a parcela de atividades improdutivas, otimizar as atividades auxiliares e aumentar a parcela das atividades produtivas. ABSTRACT: The Value Stream Mapping (VSM) rescues the transparency of processes to manage production, enabling the elimination of activities that do not add value and optimize conversion. This paper applies the MFV to seal masonry process and identifies what are the losses and failures in the process. The research carried out in construction company of the city of Goiânia is classified as a case study, with qualitative and quantitative approaches. The flow of activities were characterized and elaborated a MFV current and future production of conventional masonry process using non-structural concrete blocks in a residential building. As results, it was possible to characterize the activities and quantify the impact of unproductive activities and process aids. The main contribution was to identify the losses and failures in the process, proposing improvements in order to reduce the number of unproductive activities, optimize auxiliary activities and increase the share of productive activities.

In this paper, we consider the application of Green Value Stream Mapping for greening the information technology functional area of organizations. We advocate the use of Information Technology Infrastructure Library (ITIL) processes to consider value stream maps for both the manufacturing side of the IT department as well as its service delivery arm. In addition, we present steps to be taken by the IT department to eliminate waste in each of seven green waste areas and consider the impact of new technologies for greening the IT department.

Currently, the topic of introducing lean production is becoming more and more relevant, which is confirmed by the number of enterprises involved in this process, as well as widespread coverage in the media and popular science publications. The economic component of these projects plays a special role in the implementation of lean production, since with the correct calculation of the economy at the start, the rate of implementation is much higher, and the percentage of adoption of the implemented tools is higher. Today there are many ways to calculate the economic effect, but most of them are general in nature and do not fully demonstrate the specific results of changing processes. In addition, natural rather than financial indicators are often used, which complicates the overall assessment of the efficiency of the applied solutions. The purpose of this article is to assess the impact of value stream mapping, as a key tool of lean production, on eliminating losses and improving the productivity of the enterprise as a whole. The practical basis of the research was the experience of implementing lean manufacturing in more than 2 thousand commercial enterprises of various industries, with revenue from 100 million to 25 billion and an average number of 10 to 10 000 people.

SummaryCase reports cited in Medline or Biological Abstracts (1966-1996) were reviewed to evaluate the impact of vitamin K1 dietary intake on the stability of anticoagulant control in patients using coumarin derivatives. Reported nutrient-drug interactions cannot always be explained by the vitamin K1 content of the food items. However, metabolic data indicate that a consistent dietary intake of vitamin K is important to attain a daily equilibrium in vitamin K status. We report a diet that provides a stable intake of vitamin K1, equivalent to the current U.S. Recommended Dietary Allowance, using food composition data derived from high-performance liquid chromatography. Inconsistencies in the published literature indicate that prospective clinical studies should be undertaken to clarify the putative dietary vitamin K1-coumarin interaction. The dietary guidelines reported here may be used in such studies.
