How to construct specifications? A set of engineering targets that a product has to satisfy. Specifications are measurable criteria,goals for the design team. Specification consists of a metric and a Value metric:total weight,torque,speed,... Value:between 5-7 Ibs.,100 in-lb min.,.. Target specifications are set before conceptual design. Specifications are refined after product concept has been selected. Specifications are frequently revisited and modified during the design process

How to construct specifications? Different Forms of Value A particular number-load capacity,2000 lbs. A range -weight between 10-20 Ibs. An inequality-speed less the 10 ft/sec.Or speed more than 5 ft/sec. "It is desired to make the product as light as possible" is a wish requirement not an engineering specification
Different Forms of Value A particular number – load capacity, 2000 lbs. A range – weight between 10-20 lbs. An inequality – speed less the 10 ft/sec. Or speed more than 5 ft/sec. “It is desired to make the product as light as possible” is a wish requirement not an engineering specification. How to construct specifications?
