Learning objectives

A first educational objective of the course is to provide the student, through the lectures of the course, with the knowledge necessary to describe Information Systems and the ability to understand how they fit into the organizational structures of the company to support the business. The student will learn a series of concepts essential for the understanding of information systems related in particular to:- the nature and main characteristics of business processes;- the main aspects and methods related to project management;- management and improvement of business processes through IT, with particular reference to a number of types of information systems- the role of the Internet in business processes.- the structure and technology of computer systems oriented to organizations;- the basic principles of information system security.A second objective is to provide the student, also through some practical exercises, with a first set of methodologies, conceptual tools and technical tools to be able to autonomously frame the salient aspects of planning, analysis and design of Information Systems, evaluating and identifying the strategies of acquisition which are more appropriate to the context under consideration.The course is designed to ensure that the student acquires the skills to apply the knowledge and understanding listed above in order to be able to:- analyze business processes and their needs and identify the IT and network solutions for Business Support Information Systems;- analyze project graphs to determine timing and critical activities;- analyze and describe the architecture of the company's computing infrastructure;- evaluate the main security features (logical and physical) of the IT systems appropriate for the characteristics and business purposes of companies.Making judgments: Students must be able to understand and critically evaluate the main types of information systems and to correlate them to the needs and functions of the company.Communication skills: Through lectures and the interaction with the teacher, the student will be able to acquire the specific vocabulary of the problems, methods and solutions related to the Information Systems, to be verified also through the oral evaluation.Learning skills: The student who has attended the course will be able to deepen their knowledge in Information Systems through the independent consultation of books, scientific papers or technical magazines, even beyond the topics covered in class, to be able to enter effectively into a labour market which is increasingly digital or to undertake further training.

Teaching methods

During the lectures, topics related to the business information systems will be presented as indicated in the course program.During the course a number of application cases will also be presented. They will be analyzed and tackled for design in a highly interactive way with students. The course will also include a number of lab exercises regards selected topics of the theoretical part.

Assessment methods and criteria

The summative evaluation of learning happens in two moments:

1) a written test (conducted either in the only midterm examination or in the normal exam sessions) regarding exercises and/or questions on planning, analysis and design of the information system. The written exam aims at assessing acquired knowledge and skills in the area of Information Systems planning, analysis and design. The duration of the written test is 3 hours and student are not allowed to use notes or books. The written exam is rated in a 0-30 scale. The date of the midterm examination will be communicated to students at least one month ahead.

2) an oral examination consisting of two questions related to the theoretical topics of the course which are not part of the written exam. It mainly aims at assessing general and descriptive acquired knowledge on Information Systems. The oral test is evaluated on a scale of 0-30.The final grading (0-30 scale) is derived as the arithmetic mean of the grades of the written and oral tests.The grading of the written test is communicated within two weeks following the test, and it will be published on the Elly web platform.The grading of the oral test is communicated immediately at the end of the test. Note that online registration for the examinations is mandatory both in the case of the written test and in the case of the oral examination.N.B During the lectures, the teacher will present and administer partial training tests, useful to monitor the achievement of learning objectives and provide ongoing feedback to students, ahead of the midterm and the regular examinations.
