According to van Echtelt andWynstra (2001), the input to the model can be divided into
driving and enabling factors. Driving factors are defined as antecedent conditions in a
company’s internal and external environment that drive towards a specific form and
extent of integrated product development. Examples of driving factors are: market
uncertainty, R&D dependence, supplier dependence, company size as well as customer and
supplier market competition. Enabling factors are defined as a set of factors or conditions
whose presence help a company organise the required integrated product development
including factors such as: internal organisation of purchasing and development team,
exchange of information, compatibility of culture as well as trust and social climate.
Wynstra et al. (2000) investigated driving and enabling factors in the context of purchasing
involvement in product development and used a straightforward definition of the two.
Driving factors were defined as driving the need for purchasing involvement while
enabling factors were defined as enabling the involvement of purchasing.
