customer, so that he underst<strong>and</strong>s that we will only make a sketchy<br />
model. If he wants us to calculate the dimensions more precisely, he<br />
will need a new more ref<strong>in</strong>ed model.’<br />
Hans asks Liz what he is responsible <strong>for</strong>: ‘You are responsible <strong>for</strong> the<br />
strength calculations, I only calculate the stiffnesses?’<br />
Liz: ‘I th<strong>in</strong>k that this is really a part of report<strong>in</strong>g to the customer.'<br />
When the eng<strong>in</strong>eers were work<strong>in</strong>g together <strong>and</strong> try<strong>in</strong>g to decide what to do<br />
<strong>and</strong> what option would “work” a number of different ways were used to reach a<br />
decision. Liz <strong>and</strong> Hans <strong>and</strong> the other eng<strong>in</strong>eers that were sometimes <strong>in</strong>volved<br />
tried to conv<strong>in</strong>ce each other. They tried to reach a k<strong>in</strong>d of consensus, although<br />
they did not always do this explicitly. Sometimes there was no separate step of<br />
conv<strong>in</strong>c<strong>in</strong>g the other(s) because the scenario was sketched as a team. This<br />
occurred, <strong>for</strong> example when Liz <strong>and</strong> Hans were look<strong>in</strong>g at the f<strong>in</strong>ite element<br />
model <strong>and</strong> were th<strong>in</strong>k<strong>in</strong>g about chang<strong>in</strong>g the thickness of some materials <strong>and</strong><br />
what the <strong>in</strong>fluence would be on the total de<strong>for</strong>mation of the trailer under a<br />
certa<strong>in</strong> load. There were also situations <strong>in</strong> which one of the eng<strong>in</strong>eers had<br />
already made a scenario or had an idea about what to do. Usually this eng<strong>in</strong>eer<br />
tried to conv<strong>in</strong>ce the other(s) that his or her idea was sound. The other eng<strong>in</strong>eers<br />
could be conv<strong>in</strong>ced or they could disagree. If agreement was reached discussion<br />
on the topic was only started aga<strong>in</strong> when new <strong>in</strong><strong>for</strong>mation made this necessary.<br />
If there was still disagreement then the one responsible <strong>for</strong> the decision decided<br />
what was to be done, <strong>in</strong> this case Liz. The other eng<strong>in</strong>eer(s) could then close the<br />
discussion with words like “We will see what happens”. The discussion on the<br />
topic was not closed if disagreement rema<strong>in</strong>ed even though a decision had been<br />
made. The discussion could be started aga<strong>in</strong> at any time.<br />
In another project per<strong>for</strong>med simultaneously with this trailer <strong>design</strong> process<br />
at the eng<strong>in</strong>eer<strong>in</strong>g company, I observed that there was another way of mak<strong>in</strong>g<br />
decisions if tasks were divided <strong>in</strong> a way that every eng<strong>in</strong>eer was responsible <strong>for</strong><br />
certa<strong>in</strong> parts of the <strong>design</strong>. The one who was responsible <strong>for</strong> <strong>design</strong><strong>in</strong>g a part<br />
decided. This could make discussion on the contents of decisions superfluous,<br />
but was not necessarily so. The eng<strong>in</strong>eers liked to test their ideas aga<strong>in</strong>st<br />
colleagues, so an eng<strong>in</strong>eer might start a discussion on a topic he or she was<br />
responsible <strong>for</strong>.<br />
When there was a meet<strong>in</strong>g between the eng<strong>in</strong>eer<strong>in</strong>g company <strong>and</strong> the<br />
customer, they chose to sit on opposite sites of the table, eng<strong>in</strong>eers from the<br />
eng<strong>in</strong>eer<strong>in</strong>g company on one side <strong>and</strong> the customer <strong>and</strong> his advis<strong>in</strong>g eng<strong>in</strong>eer<br />
on the other side. In such meet<strong>in</strong>gs the CLC eng<strong>in</strong>eers all seemed to defend one<br />
idea, there seemed to be no disagreement among the CLC eng<strong>in</strong>eers. Dur<strong>in</strong>g
