The course (which is compulsory for the Bachelor of Science in “Ingegneria della Produzione Industriale”) focuses on the major methodologies, good practices and tools for achieving Quality within industrial environments. Course objectives are: • Stimulating student awareness of the concepts of Quality of a product/service and competition-oriented design. • Describing the main techniques of Process Control and Acceptance Monitoring in the acquisition phase of semi-processed/raw-materials and during the introduction on the market of end-products/services. • Stimulating capabilities of design and verification of the entire supply chain, starting from the market demand analysis, up to the policies of outsourcing/insourcing of facilities and support structures. Real evidences of Quality practitioners and case studies will complement the course.

Knowledge of the major techniques for implementing Quality Management Systems, according to existing standards. Mastery of tools and techniques to achieve Quality within industrial environments: FMECA (Failure Mode, Effects and Criticality Analysis), QFD (Quality Function Deployment), SPC (Statistical Process Control), etc.. At the end of the course, students will be able to operate in industrial environments in which Quality Management and SPC techniques are implemented.

Essentials of Mathematical Analysis, Statistics and Production Technologies.

1. Preliminary concepts Terms and definitions. Introduction of Quality Management techniques in industry. The importance of Quality in design and production. Basic notions on Statistics. 2. Quality in design Offered, expected and perceived Quality. Quality Function Deployment (QFD). Customer Requirements, Technical Characteristics and Relationship Matrix. Prioritization of the Technical Characteristics. FMECA (Failure Mode, Effects and Criticality Analysis). Quality Costs. 3. Statistical Process Control (SPC) Introduction to statistical methods for Quality control. Variability and natural tolerance of the process. Variability propagation and the Delta method. Control charts for variables and attributes. Operating Characteristic (OC) curves relating to control charts. Design and construction of control charts. Process Capability Ratios (PCRs). Theory of inspection and acceptance sampling plans. Sampling plans for attributes. OC curves relating to sampling plans. Design of sampling plans for attributes

The central topics of the course will be illustrated through a number of complementary activities that will take place in the classroom and/or laboratory, including an optional group-project about the application of QFD and FMECA. Other activities will cover: • analysis of case studies and real-life testimonials from company managers; • application of QFD and benchmarking techniques; • construction and use of control charts and sampling plans.

... The course materials will be taught through a series of lectures, in which classroom participation is strongly encouraged. The exam will be based on a written test, of about two hours, containing: (i) exercises concerning SPC techniques; (ii) theoretical open questions concerning the totality of the topics covered. Exercises and theoretical questions will be "balanced" in order to ascertain the achievement of the learning outcomes, expected from the course. Students will use the material indicated by the professor – i.e., specific statistical tables and a free-formula sheet; lecture notes, books, manuals, laptops, tablets or smartphones will be strictly forbidden. During the course, students will also be involved in an optional teamwork project. In the case of positive evaluation, team members will gain 1 or 2 extra points. The maximum possible grade for the exam will be 30L, including the said extra points. Even though the standard exam is written, the professor reserves the right to perform a supplemental oral exam. On the other hand, requests for oral examination by students will not be accepted.

Gli studenti e le studentesse con disabilità o con Disturbi Specifici di Apprendimento (DSA), oltre alla segnalazione tramite procedura informatizzata, sono invitati a comunicare anche direttamente al/la docente titolare dell'insegnamento, con un preavviso non inferiore ad una settimana dall'avvio della sessione d'esame, gli strumenti compensativi concordati con l'Unità Special Needs, al fine di permettere al/la docente la declinazione più idonea in riferimento alla specifica tipologia di esame.

Modalità di esame: Prova scritta tramite PC con l'utilizzo della piattaforma di ateneo; Elaborato progettuale in gruppo;

It is not necessary to change the usual method of preparation with respect to the classical exam. The exam will be organized in the form of a “quiz”, with a variety of problems and questions (roughly, between 5 and 10), trying to reproduce the classical configuration illustrated in class. Also, the typical topics are the same ones illustrated in class, i.e.: a. Statistical Process Control; a.0 Probability calculation and hypothesis testing; a.1 Delta method; a.2 Control charts; a.3 Sampling plans; b. Quality in design; b.1 General notions; b.2 Quality Function Deployment (QFD); b.3 Failure Mode, Effects, and Criticality Analysis (FMECA). The exam mainly consists of problems involving calculations, with the addition of some multiple-choice theoretical questions. In case of wrong answers to multiple-choice questions, penalties may be applied (e.g., -0.5 point); therefore, it is advisable to omit the answer in case of doubt, avoiding “random guessing”. Problems involving calculations are not “sequential”, just to avoid that calculation errors on the initial answers lead to a sort of “error propagation” on the subsequent answers. Questions/problems are fully “customized”, both (1) in terms of numerical data for problems involving calculations and (2) in terms of order/combination for multiple-choice questions. As in any normal exam, you can use paper, pen, tables, formulary and calculator. A technical difficulty of the examination method is to fill in the answer boxes. Since any typing or rounding error may affect the correct outcome of your test, it is recommended to be very careful. In any case, appropriate "tolerance ranges" will be considered around the correct results, to take into account possible rounding errors. For numerical answers, the platform accepts both “.” and “,” as decimal separator. Also, students must report the probabilities as numbers between 0 and 1 and not in percentage form (e.g., a probability of 2.5% should be reported as “0.025”, not “2.5%”). For each problem/question, a score will be reported. The total mark will obviously be 30 (plus the 2-point bonus related to the project work). Even though the standard exam is an online quiz, the professor reserves the right to perform a supplemental oral exam. On the other hand, requests for oral examination by students will not be accepted. For students who wish to do so, it will be possible to interact with the teacher during the exam through an optional Virtual Classroom, which can be activated after the beginning of the exam, pressing a dedicated button in the top-left corner of the quiz window, below the countdown. After the publication of the result of the exam on the Teaching Portal, students are allowed to reject their positive mark by sending an e-mail to the teacher, before the mark-registration date (which will be announced later). Finally, students are invited to carefully consider the rector's guidelines for online exams and the FAQs available on the course material.
