This paper aims to express the maturity and dynamism of welding in industry. It follows the direct observation of international construction standards and rules, here described as an introduction to the most relevant themes in the area of welding processes. Quality management in welded construction involves well-regulated procedures which are, however, so vast that they are of great complexity. In fact, there are hundreds of rules to apply to each specific case. This makes it imperative to have a welding coordinator, at least in cases of greater responsibility. In fact, the application of the rules presents yet another difficulty: along with the breadth of the rules, each country may adopt certain special requirements in their own case. Thus, it is essential to know the necessary path for the proper development of responsible work. First, one must know the various welding processes, their advantages and limitations; then one must identify the regulations applicable to the work concerned; and finally, one must know what tests and qualifications are required, including the expected defects and acceptance criteria. One purpose of this work is to show the necessary path for the implementation of a welding quality management system in metal construction, as well as to present the numerous applicable norms, both for the welder and the welding coordinator, but also for the process and the product. This paper also presents an analysis of how to obtain the CE marking (Conformité Européene) for a welded metal construction and which normative ramifications apply.

ABSTRACT Quality standards as part of an effective quality management system (QMS) are the cornerstone for generating high-quality test results. Next-generation sequencing (NGS) has the potential to improve both clinical diagnostics and public health surveillance efforts in multiple areas, including infectious diseases. However, the laboratories adopting NGS methods face significant challenges due to the complex and modular process design. This document summarizes the first phase of quality system guidance developed by the Centers for Disease Control and Prevention (CDC) NGS Quality Workgroup. The quality system essentials of personnel, equipment, and process management (quality control and validation) were prioritized based on a risk assessment using information gathered from participating CDC laboratories. Here, we present a prioritized QMS framework, including procedures and documentation tools, to assist laboratory implementation and maintenance of quality practices for NGS workflows.

The current global trend in healthcare is standardization and quality management issues. Tomsk region is one of the pilot regions in this matter. The article reflects the aspects of implementing a quality management system in healthcare. The issue of the implementation of the “Lean Polyclinic” project, as a QMS tool, is revealed. It was noted that in most organizations this project is far from being completed. The author identifies the main errors during the implementation of the project, and focuses on the process approach as the foundation of a quality management system. A properly built model of process interaction allows you to quickly and efficiently implement QMS in healthcare organizations. The author spelled out the steps for implementing the process approach, and also proposed a model of process management using the example of a medical organization.

In recent years, most universities are facing with the problem of quality management in higher-education systems and institutions. The Countries that have signed the Bologna Declaration are enforced to implement an internal system for quality assurance. One of the key element of a quality management system is the process modelling with delineation of responsibility, authority, procedures and plans. This chapter describes the use of the Business Process Management to support the higher Education Management System at University of Basilicata. The case study developed concerns the following steps: visualizing, measuring, analysing by a simulation environment, and improving the management system. The original contribution of the research concerns the development of a simulation environment using BIZAGI modeller based on BPMN notation in order to analyse and improve the performance of the case study investigated. Moreover, the use of a software based on BPMN can improve quality (error rate reduction), efficiency (saving of time) and agility (implementation of processes of changes).

Bharti Airtel Limited was a leading private sector provider of telecommunication services in India, with a customer base of 8.73 million as of July 2004. The company had two branch companies — Bharti Infotel (that dealt with fixed line, long distance, and enterprise services) and Bharti Cellular (that dealt with mobile telephone services). This case is about the six sigma implementation at Bharti Infotel. The case briefly discusses the business imperatives in the fast changing Indian telecommunications industry. The industry was a monopoly for over half a century after independence and had recently been deregulated with the private players competing with the state-owned BSNL. The industry had exploded in the recent years with increasing number of players, falling tariffs, and improving technology. Stiff competition in the industry meant that any competitive action by a company was immediately imitated by others. Therefore the only sources of competitive advantage in the industry were “quality of service” and “speed”. This case discusses the various steps in the implementation of six sigma quality management system in the company. The company had already implemented Business Process Management Systems (BPMS) and had begun monitoring their performance on the Non-Financial Parameters (NFPs). The six sigma initiative was expected to leverage on these initiatives. Following the six sigma initiative was the Knowledge Management (KM) initiative that was intended to help share the best practices and learning from the six sigma projects across the entire organization. This case highlights the contribution of the six sigma quality management initiative to the company's business strategy, and helps students analyze the process of implementing and institutionalizing the six sigma initiative. The case enables the readers to appreciate the business benefits of six sigma implementation and how it fosters innovation.

Process oriented approach in quality management system has been introduced with ISO9001:2000. The international standard promotes the adoption of a process approach when developing, implementing and improving the effectiveness of a QMS to enhance customer satisfaction by meeting customer requirement. The advantage of process approach is to link all parties in scope of business of the organization from suppliers, internal departments of organization to gather to make B2B communication and integration. In this paper, the process approach is defined based on QMS requirement. Supply department was proposed for implementation of process. Purchasing process was designed as a linkage between supplier and internal company departments. Performance indicators were developed and measured accordingly. It shows that process management can improve delivery capability, quality and monitor price of supplied parts by suppliers.

The article is devoted to solving an important scientific problem - the formation of a management system for strategic performance and adaptation of enterprises implementing construction projects to change. Theoretical approaches to the classification of strategic performance of enterprises are studied and systematized, which allowed to highlight the need to take into account the foreseeable and unpredictable opportunities for change in the enterprise, focusing on external and internal environmental factors that affect the formation of quality management system. Theoretical and methodological approach to the formation of the quality management system is based on the formation and implementation of basic elements and components (organizational, economic, legal, technological and social) using methods and techniques of a mixed approach (managerial, functional and process). The concept of the tool base for modeling strategic performance as a model for managing the adaptation of the enterprise to change is proposed, which has a number of advantages in practical use by enterprises: it is based on the vision, mission and main development objectives formed by the enterprise; takes into account the factors of cyclicality, which are a reflection of existing trends in the economy of the world and the country and directly affect the development of the enterprise; provides opportunities to conduct a comprehensive assessment of the external and internal environment of the enterprise, to calculate and predict the psychological and qualification level of staff and the level of perception of change by these employees; is based on the theoretical foundations of the process approach in the development of mechanisms for managing individual components based on business process management; is developed in accordance with the main functions of management, which provides an opportunity to take into account the sequence of actions and the formation of regulations for the management of enterprises. In turn, the main components of the management system of adaptation of enterprises to change take into account the need for systematization and management of ancillary processes: infrastructure and information; the need for feedback, adjustment of the developed measures of the regulations of strategic performance management as a result of monitoring and control over the consequences of its implementation.
