Conclusions of the empirical study<br />

to ask advice from a certify<strong>in</strong>g organisation. Thus <strong>in</strong> normal <strong>design</strong>s there were<br />

fewer operationalisations made from scratch. The availability of a regulative<br />

framework did not mean that all of the ethical <strong>issues</strong> could be decided on us<strong>in</strong>g<br />

such a framework. Some subjects were not covered by the regulative framework.<br />

For example, <strong>in</strong> the bridge case the prevention of misuse of the bridge was not<br />

part of the regulative framework, while <strong>in</strong> the pip<strong>in</strong>g <strong>and</strong> equipment case the<br />

regulative framework did not provide rules <strong>for</strong> establish<strong>in</strong>g load <strong>and</strong> accident<br />

scenarios. The Notified Body could give advice on load <strong>and</strong> accident scenarios<br />

but it was not allowed to check accident scenarios. When a regulative framework<br />

did not give guidance <strong>and</strong> rules on a subject the eng<strong>in</strong>eers fell back to rely<strong>in</strong>g on<br />

company rules, their own <strong>design</strong> experience or seek<strong>in</strong>g advice from an<br />

organization that had a lot of experience with the subject. So <strong>in</strong> the presented<br />

cases the regulative framework was complemented with comply<strong>in</strong>g to company<br />

rules, us<strong>in</strong>g <strong>design</strong> experience <strong>and</strong> seek<strong>in</strong>g expert advice.<br />

Only a few references were made to regulative frameworks or ideas from the<br />

regulative framework were rejected <strong>in</strong> the radical <strong>design</strong> cases. In these cases the<br />

approaches <strong>for</strong> deal<strong>in</strong>g with ethical <strong>issues</strong> were to rely on personal or <strong>design</strong><br />

experience <strong>and</strong>/or to discuss such <strong>issues</strong> with the customer.<br />

The regulative framework perta<strong>in</strong><strong>in</strong>g to car safety was rejected <strong>in</strong> the<br />

DutchEVO lightweight car case <strong>and</strong> <strong>in</strong> the trailer case the regulative framework<br />

concern<strong>in</strong>g trucks <strong>and</strong> trailers was only used to obta<strong>in</strong> maximum dimensions,<br />

mass <strong>and</strong> pneumatic spr<strong>in</strong>gs. Operationalisations of ethical <strong>issues</strong> were made<br />

based on <strong>in</strong>ternal norms exist<strong>in</strong>g <strong>in</strong> the company <strong>design</strong><strong>in</strong>g the trailer. These<br />

<strong>in</strong>ternal norms were also of help <strong>in</strong> decid<strong>in</strong>g what trade-offs were deemed<br />

acceptable by the <strong>design</strong> team. The <strong>in</strong>ternal norms consisted of ideas, rules <strong>and</strong><br />

guidel<strong>in</strong>es as to what a good <strong>design</strong> is <strong>and</strong> how a <strong>design</strong> should be made. Such<br />

<strong>in</strong>ternal norms are shared by a <strong>design</strong> team, but can also be shared by (the<br />

department of) an organisation <strong>in</strong> which the <strong>design</strong> team works. In the radical<br />

<strong>design</strong> cases, <strong>in</strong>ternal norms were developed based on <strong>design</strong> experience,<br />

educational background <strong>and</strong> personal experience. In addition to these <strong>in</strong>ternal<br />

norms, customer norms can be used <strong>in</strong> operationalisations <strong>and</strong> <strong>in</strong> the mak<strong>in</strong>g of<br />

trade-offs.<br />

In the trailer case, a lot of discussions was devoted to what load scenarios<br />

should be used to test the reliability of the trailer. These load scenarios were part<br />

of the operationalisation of the reliability of the trailer, <strong>and</strong> as <strong>in</strong>dicated <strong>in</strong><br />

chapter 7, safety was equated with reliability. The department of the eng<strong>in</strong>eer<strong>in</strong>g<br />

company <strong>in</strong> which the eng<strong>in</strong>eers worked specialised <strong>in</strong> lightweight composite<br />

<strong>design</strong>. Internal norms <strong>and</strong> ideas on good <strong>design</strong> practice existed with<strong>in</strong> the<br />

department <strong>and</strong> were based upon the department’s <strong>design</strong> experience with<br />
