GESTIONE DEI SISTEMI DI QUALITA'

Academic Year 2026/2027 - Teacher: GIOVANNI CELANO

Expected Learning Outcomes

The course provides students with content related to quantitative concepts and methods used to implement a quality management system. Particular emphasis is placed on quality systems management according to the ISO 9001 standard, as well as its application within civil engineering. The principles of managing improvement projects according to the Six Sigma approach are also described. Furthermore, the course aims to provide students with basic statistical skills for quality control in business processes. In particular, case studies for data analysis in the field of quality are presented and solved using Microsoft Excel and Minitab® software.

Course Structure

Direct Teaching:

Activities focus on the delivery of theoretical knowledge and reference regulatory frameworks through:

  • Presentation, analysis, and discussion of theoretical and methodological content.
  • Critical review and guided commentary on reference standards and technical regulations (ISO 9000 and industry-specific standards).
  • Weekly guided tutorials dedicated to solving quantitative problems and applying statistical formulas and models.

Interactive Learning:

Activities are designed to stimulate active learning, analytical skills, and teamwork through:

  • Resolution and discussion of real-world scenarios applied to civil engineering, utilizing Microsoft Excel and Minitab® software.
  • Collaborative group activities (composed of 2–3 students) to complete in-class practical exercises. This format is structured to enhance process-oriented problem-solving skills and develop soft skills in teamwork.

If the course is delivered in blended or remote mode, appropriate adjustments may be made to the above, in order to ensure consistency with the syllabus.

Learning Assessment

Learning Assessment Procedures

Student assessment is based exclusively on a written exam, which consists of multiple-choice questions, open-ended questions, and quantitative exercises.

The multiple-choice and open-ended questions account for 50% of the final exam grade. These questions primarily cover the content presented in modules 1, 2, and 5 of the course schedule. The exam is administered through the online platform exam.net. The objective is to assess students' knowledge of the quality management topics discussed in class, with particular reference to standards and regulations. The open-ended questions aim to verify the student's ability to describe key concepts of quality management clearly and with a proper command of the terminology.

The quantitative exercises account for the remaining 50% of the final exam grade. Solving these exercises requires the implementation of basic statistical methods for quality control in the construction sector and acceptance sampling for concrete. The exercises primarily cover the content presented in modules 3, 4, and 5 of the course schedule. The exercises are designed to present students with scenarios similar to real-world cases, where they must apply the skills they have acquired by choosing the correct tool to solve the problem.

During the teaching period, exclusively for students attending the course, two mid-term exams will be held (mid-semester and at the end of the semester) using the same format as the final exam. Passing both mid-term exams entitles the student to pass the course; the final grade will be the sum of the scores obtained in each test.

Learning assessment may also be carried out on-line, should the conditions require it.

To ensure equal opportunities and in compliance with current laws, interested students may request a personal interview in order to plan any compensatory and/or dispensatory measures based on educational objectives and specific needs. Students can also contact the CInAP (Centro per l’Integrazione Attiva e Partecipata — Servizi per le Disabilità e/o i DSA) referring teacher within their department (https://www.cinap.unict.it/content/referenti).
