THE TECHNOLOGICAL WORLD SPECIFICATIONS
SPECIFICATIONS • Requirements and needs (technical, financial and other obligation) necessary for the project to be carried out.
CONSTRAINTS The physical constraints The technical constraints The economic constraints The industrial constraints The human constraints The environmental constraints
THE PHYSICAL CONSTRAINTS • Concerns all the natural elements ( air, water, dirt, etc) • Example : • Exposed to rain = rust This Photo by Unknown Author is licensed under CC BY-SA
THE TECHNICAL CONSTRAINTS • Factors that affect the operation of the object • Example : • Maximum speed of the bicycle • How long the batterie last
