INTRODUCTION FOR HEATING, VENTILATION & AIR-CONDITIONING (HVAC)

This course is industry designed, to provide a broad understanding of the improvement methodology, concepts, and process. The methodology is presented with case studies and examples drawn from service, business process and industrial applications. With a heavy practice orientation, as much as a third of your time will be spent working through interactive practical exercises and assessments.

COURSE OBJECTIVES

This training program is designed to provide an understanding of engineering related problems related to industry globally and a clear sense of what is required to effectively structure, establish measurements and solve problems. Participants will learn the goals and deliverables behind the solutions. Methodology as well as the most commonly used tools within each phase will be discussed. Participants will also learn how to support a problem solving initiative within their organization.
