operation it results from, whereas a good can be described independently from<br />

the upstream process that generates it. Once this issue accepted, one can call<br />

“quality of a service” the degree of adequacy of the actually provided service<br />

with the scheduled (theoretical) program it is supposed to fulfill.<br />

In this respect, the usual measure units of freight transport are poor<br />

(whether one uses tons or ton-kilometers does not make much difference), as<br />

they do not include transport key characteristics such as speed, safety, punctuality,<br />

flexibility, etc. The appraisal of this quality belongs both to the carrier and to<br />

the shipper, involved in the bilateral relationship of transport production and<br />

consumption.<br />

The measurement of quality can rely on the assessment of the process, according<br />

to its technical content: one can check the proper condition of vehicles,<br />

measure the lead-time, the frequency of transport, the punctuality of picking<br />

up, etc. Or it can rely on the assessment of the result, considering integrity of<br />

consignments, reliability concerning delivery address or punctuality of delivery,<br />

completeness of consignment (no missing parcel in a range of expected deliveries,<br />

e. g. when several spare parts are necessary to repair a machine), accuracy<br />

of documents (bill of lading, invoice, etc.) and finally flexibility (both for short<br />

range response to unexpected events and for long range innovation).<br />

Quality is of course specific to each transport operation, its definition has to<br />

be determined according to criterions and their weightings have to be set by the<br />

shipper and depending on his products. Some of these criterions are measurable<br />

and others more subjective. They correspond to an expected level of performance,<br />

and the comparison of actual adequacy with theoretical “quality” sets the<br />

rate of success or of failure, at least when the operation is recurrent and enables<br />

a statistics measurement.<br />

Total quality does not exist (or it would have an infinite cost), a tolerable rate<br />

of failure is set, implicit or explicit, according to an economic appraisal. Optimum<br />

quality is not maximum quality, a trade-off is set between logistics requirements<br />

and utility one the one hand, corresponding costs on the other hand, according<br />

to different levels of quality (see Fig. 51).<br />
