7.Set target figures to be achieved for the engineering characteristics.
lThese information are obtained from the comparison with competitor products or from trials with customers. These can be set comparative to competitors.
6.Identify relevant interactions between engineering characteristics,
lThe roof matrix provides the check and gives an opportunity to recognise strong connections
5.Identify the relationship between engineering characteristics and product attributes,
lThe strength of the relationship can be expressed by numbers or symbols.
4.Draw a matrix of product attributes against engineering characteristics,
lAll engineering characteristics that influence any of product attributes should be included and expressed in terms of measurable units.
