A method of design and manufacture of an assembly of components including selecting KCs of the type, Product KCs, Assembly KCs or Manufacturing KCs is provided. The method includes the steps of identifying potential KCs and carrying out a risk assessment for variation of the potential KCs based upon four values, namely probability of failure or variation; the severity of the variation; the detectability of the variation, and the repairability of the variation. Scores attributed to each said value may then be multiplied together to produce the risk assessment. Once the KCs have been selected, a process of feature identification and classification for the KC may be carried out, followed by establishment of assembly precedence of features for the KC.
