Subject fundamentals
The course aims to present the methodologies used in the processes of innovation and improvement of products and processes. In particular will be dealt with the methodologies used to design and manage production specification in the engineering of innovative products, time compression techniques and statistical based methodologies to asses the quality and reliability of products, improve the quality of products and processes, for the introduction and evaluation of innovative products and processes.
Expected learning outcomes
Knowledge of the techniques of time compression for the product / process development;
Knowledge-of statistical-based methodologies to asses the quality and reliability of products and to improve the quality of products and processes; knowledge-of statistical-based methodologies for the introduction and evaluation of innovative products and processes (robust design, six sigma etc.).
Ability to adapt production to functional specification of product and to evaluate their acceptance, especially in the phases of introduction of products / processes.
Ability to provide statistical methodological support to specialists involved in the activities of R & D, and to coordinate the evaluation activities.

Basic ideas on six sigma methodology

Manufacturing operations.
Operations and processes
Processes improvement and innovation.
Process design:
- Positioning
- Process performance objective
- Process mapping
- Process task and capacity
- Process variability
Methodology for diagnostic and improvements of manufacturing system
- Absolute benchmarking and value stream mapping.
- Integration of value stream mapping and discrete events simulation (descriptive analysis data , queuing theory)
- Measures of Manufacturing performance
Lean innovation
- Push and pull production systems
- Lean synchronisation
Delivery modes
Practical examples will be provided to the students in the course web page (didactical portal) ; these examples will be discussed during the tutorials.

During the course the students will attend lectures and practical exercise in classroom and Informatic labs. Groups of students which regularly attend theoretical and practical lectures can work on a case study and produce a technical report that can be evaluated in the final examination.
Texts, readings, handouts and other learning resources
Lecture notes in the course website will be provided.

Assessment and grading criteria
The exam consists of two parts, an written test of "Process innovation" and a subsequent oral of "Product innovation".
The written test of Process innovation assesses the knowledge and skills acquired through exercises and theoretical questions. The written test may be partially replaced, only by students who have attended at least 70% of lectures and tutorials, with the presentation and discussion of the technical report carried out as part of the course (maximum score 16/30). The technical report must be submitted by the date set by the teacher (approximately 10 days before the first exam session); if this deadline is not met, the student will have to take the entire written test.
The oral part of the Product Innovation assesses the knowledge of statistical tools for assessing the quality and reliability of products and for the improvement of products and processes. To sit for the oral of Product Innovation is necessary to have passed (min. 18/30) the part of Process Innovation
The final score will be the mean of the two parts.
If one part is failed the student must repeat the total exam (written and oral)
The students can conserve the vote of Process Innovation only during the ongoing examination session. In case the student does not succeed in the exam of Product Innovation within the same session, he will have to repeat both exams in the next exam session.
