Nonetheless, exchanges should not be written off completely. They are gaining ground in sectors in which commodities can be separated from other parts of the business. The major obstacle appears to be codification of difficult-to-estimate parameters (e. g., quality of customer service). Exchanges flounder when custom-ers discover they need something unexpected: emergency or rush service, design know-how, and so forth. Furthermore, just establishing a reliable relationship is costly. Expertise, credit worthiness, and general qualification to bid must be fac-tored in, none of which is easy to do.

if interdependence implies a two-way dependence, and if each partner is equally dependent on the other for success, then there is an equal commitment to the making the partnership successful. the advantage is sustainability of the relationship, the disadvantage is that decisions are "democratic" and therefore may take longer to reach and more likely to be a compromise (which is not always the best solution). as the interdependence moves away from equality, the decisions become more influenced by the more independent partner. in the extreme the relationship becomes more dictatorial and more like "master-slave". generally the relationship has less commitment in both directions and is more likely to be temporary.

if one generalizes (and one shouldn't), equity partnerships, which is probably what is implied by interdependence, can be slow to progress or change but durable. the extreme alternative, independent-dependent partnerships tend to be efficient but more fragile.

hope this but you will have to site your own evidence. : )
