Learning Objectives
To enable the student to understand the multifaceted aspects of the concept of quality in the context of production and services, developing the knowledge and understanding of the principles and methods for total quality management (TQM) and of the quantitative methodologies to support it, such as statistical process control and acceptance quality control (cc6).
To strengthen, in the application of these tools, the transversal skills of technical communication in written form, enriched with graphics and tables, supported by appropriate arguments (ct1, ct3, ct4).
To develop the knowledge of the most up-to-date technical standards in terms of quality management systems, their principles, the processes they describe and support (cc6, ct5).
To extend the knowledge and skills of quality management to the environmental management systems (cc6).
To provide students with the necessary knowledge to be able to participate in a company quality certification according to ISO 9000 standards, choosing and implementing quality control, defining appropriate procedures in compliance with the system certification standards and those required by regulation (ca4, ca5, ct5).
Provide students with the knowledge necessary to participate in an ISO 14000 environmental management system certification, performing an initial environmental analysis(ct5).
In pursuing the specific educational objectives of this teaching, the understanding of the systemic nature of the company organization and production systems will be strengthened with a view to problem solving (cc7), knowing the merits and limits of the methodologies learned (cc9) and their implications not only of technical-economic nature(cc10). The goal is to develop the ability to understand the constraints related to the product to be made and the technologies that can be used (ca6) to be able to choose and use the most appropriate methods for production and the most appropriate control tools (ca7) considering also the constraints not merely technical-economic (ca8).
At the end the course the student will be able to:
- Analyze the quality gap in product manufacturing and service providing.
- Establish sampling plans based on attributes or on variables. Design and use control charts.
- Roughly design a quality or environmental management system, assessing the compliance with the ISO 9001 or ISO 14001 standards
- Perform a preliminary environmental analysis

Type of Assessment
Written examination in the morning on the same day of the oral examination (ct1, ct3, ct4), based on one composite exercise of one of two main problems: 1) Statistical Process Control (control charts) with connection to process capability and 2) Acceptance Quality Control, with the economic impact on process and products.
The written examination allows to assess knowledge and understanding of quantitative methodologies supporting quality management (cc6) and, above all, the skill to integrate knowledge and capabilities, developed along the degree courses, with those specific of this matter, by choosing and correctly implementing quality control (ca4 and ca5) in order to solve production engineering problems. The student can get the sufficient mark from this written examination, by solving at least the main problems above usually consisting in the first question, and this mark accounts for 50% of the whole final mark. The student can increase the mark, reaching the top score, by answering to the additional questions that require a deeper preparation and more skills.
Students that get a sufficient mark in the written examination are orally examined in the afternoon of the same day in which they will discuss the solution of the exercises of the written examination and they will be assessed on the knowledge and understanding of principles and methodologies for Total Management of Quality (TQM), the knowledge of up-to-date technical standards, their principles, concerning quality, environment and safety (cc6).
In presenting the main elements of such approaches and the related standards, the student must demonstrate the understanding of the systemic nature of the company organization and of the production processes inside a problem solving view (cc7), taking into account product and technologies constraints (ca6), considering also the not merely technical-economic constraints.
Final mark will be based on the written examination mark, eventually corrected with the discussion during oral part, and on the ability to master technical and analytical methods and tools, on a broad vision about quality management, and on the capacity to establish links among the topics studied, as well as with those approached in other courses.
