Studio & Interdisciplinary Courses

Becoming a Leader in the Digital World

TECH 5000 1.00

In each class, students focus on building skills needed for effective entrepreneurial leadership in a digital world and build on understanding how to maximize the positive economic, social, and cultural impact of digital businesses and products.

Business Fundamentals

NBAY 5500 1.00

This course is an introduction to fundamental concepts in business management – strategy, finance and financial accounting, marketing, organizational design, operations management, and negotiations – that are crucial knowledge for any entrepreneur and/or product manager. The course will help you learn the ‘language of business,’ and prepare you to take business electives in the near term and to run your own firm or product unit in the not-too-distant future, after you graduate from Cornell Tech. Business Fundamentals is not just economics, psychology, sociology, or mathematics, but draws from all of these disciplines. As a result, some of the concepts may sound familiar to some of you, but we will focus on understanding how they are applied to real-world business problems. In order to do so, we will use business cases and exercises in addition to lectures. Analyzing a case study and the resulting deductive learning will help you think in a different way, and will teach you to be comfortable with ambiguity, uncertainty, and contingencies, which are inevitable realities of business life. The general structure of the course is to introduce core concepts in each business area – strategy, finance/accounting, marketing, organizational design, operations management, and negotiations – through a lecture and a reading and then to apply those concepts in analyzing a custom-written case that draws from current business news.

Design Thinking

NBAY 5180 1.00

This hands-on course will prepare you to be future innovators by teaching you Design Thinking, the human-centered design methodology pioneered by IDEO and Stanford founder, David Kelley. You will work on a team with peers from other disciplines so as to experience the importance of “radical collaboration.” All teams will work on the same challenge, and you will be asked to design an innovative solution to this complex problem.

Disruptive Technologies

NBAY 6120 1.00

Begins by presenting historical technological advances that created major paradigm shifts for communications. Presents advances in computer technology emphasizing the fundamentals behind the increases in processing power, video and computer graphics capabilities, and network transmission. The second half of the course covers the effect of these scientific advances on many discipline-specific areas including photography, the film industry, the entertainment and animation industry, television broadcasting, publishing, and the computer industry itself. Sessions are devoted to the social and legal issues arising from the rapid advances in electronic communication. In attempting to predict the disruptive changes of the future, it is best to understand the technologies themselves. The course is especially tailored to a business school and industrial concerns and has interactive live demonstrations at the state-of-the-art laboratory of the Program of Computer Graphics. No prior knowledge of computer science is required.

Product Management

CS 5093 1.00

This studio-based course helps students learn about and develop product management (PM) skills by putting those abilities immediately to use on their Startup Studio projects. In each session, students learn about a different aspect of product management, product design, or technology development, then practice applying it to their Startup Studio projects, working in the Studio with their project teams and with the help and critique of the practitioner instructors and sometimes visiting practitioners. By the end of the semester, students will have developed and practiced many of the fundamental product management skills required to develop new technology products, and their Startup Studio projects will have greatly benefited from the practice.

Product Studio

TECH 5900 3.00

Product Studio is the foundational studio course for product development at Cornell Tech. Students form semester-long teams and select a “How Might We” question posed by a company. During the semester students learn the basics of product development so they can apply the knowledge and skills from their degree program: identifying impactful problems to solve, product ideation and design, development process, and constructing a meaningful product narrative and complete product loop. Students present their working product, narrative, and thought process four times during the semester, after completing each of three 24-hour “studio sprints” where they will focus on developing their product and a final product presentation at the end of the semester.

Startup & Product Ideas

TECH 5100 1.00

This studio-based course helps students develop their ability to imagine, recognize, develop and improve startup ideas. In each class, students learn a different approach to product ideation or product critique, then practice that approach, working in many different teams — often with the advice of visiting entrepreneurs, VCs, domain experts, and other practitioners. Students invent and explore hundreds of startup ideas, and help each other evaluate and improve those ideas. By the end of the course, students self-organize into co-founding teams around specific startup ideas that they will pursue in Startup Studio the following semester.

Startup Studio

TECH 5910 3.00

In Startup Studio you and a team of your classmates will develop your own new product or startup idea. You’ll experience the entire process, from developing your idea, to prototyping and testing, to pitching to investors. You can even apply for a Startup Award that will provide funding and other support to help you turn your Startup Studio project to a real business.
