<p style="margin-bottom: 0.0001pt; background-image: initial; background-attachment: initial; background-size: initial; background-origin: initial; background-clip: initial; background-position: initial; background-repeat: initial;"><span style="font-size: 8.5pt; font-family: Verdana, sans-serif;">As the Notice of Violation from the United States Environmental Protection Agency (EPA) explains, the software in Volkswagen’s EA189 diesel engines detected the precise conditions that indicated when a government emissions test was being run. Then, and only then, did the control software fully enable the anti-pollution devices fitted to the vehicle.

<span style="font-size: 8.5pt; font-family: Verdana, sans-serif;">Fudging the benchmark

<p style="margin-bottom: 0.0001pt; background-image: initial; background-attachment: initial; background-size: initial; background-origin: initial; background-clip: initial; background-position: initial; background-repeat: initial;"><span style="font-family: Verdana, sans-serif; font-size: 8.5pt;">Attempts to mislead testers are unfortunately all too common in the IT industry. Benchmarks are standardised ways of measuring the performance of IT systems, but they are regularly gamed by manufacturers seeking a marketing edge.
<span style="font-family: Verdana, sans-serif; font-size: 8.5pt;"> 

<p style="margin-bottom: 0.0001pt; background-image: initial; background-attachment: initial; background-size: initial; background-origin: initial; background-clip: initial; background-position: initial; background-repeat: initial;"><span style="font-size: 8.5pt; font-family: Verdana, sans-serif;">In 2013, the technology enthusiast website AnandTech reported that many major smartphone manufacturers had written firmware that compared the name of the app currently running with a list of known benchmarks. Normally, a smartphone’s Central Processing Unit (CPU) is heavily self-monitored. It only runs at full speed for short bursts to avoid damage from overheating and to increase battery life.

<p style="margin-bottom: 0.0001pt; background-image: initial; background-attachment: initial; background-size: initial; background-origin: initial; background-clip: initial; background-position: initial; background-repeat: initial;"><span style="font-size: 8.5pt; font-family: Verdana, sans-serif;">But if a benchmark was detected, the CPU ran at full speed continuously. This slightly improved benchmark scores, but in a way that would result in flat batteries and burned pockets were it to be replicated for everything a smartphone does.

<span style="font-size: 8.5pt; font-family: Verdana, sans-serif;"><o:p></o:p>

<p style="margin-bottom: 0.0001pt; background-image: initial; background-attachment: initial; background-size: initial; background-origin: initial; background-clip: initial; background-position: initial; background-repeat: initial;"><span style="font-size: 8.5pt; font-family: Verdana, sans-serif;">Volkswagen’s public statements to date have not attributed blame to specific individuals. Bernd Osterloh, chairperson of Volkswagen’s work council and a member of the executive committee, said. “A small group has done damage to our company. We need a climate where mistakes are not hidden.”

<p style="margin-bottom: 0.0001pt; background-image: initial; background-attachment: initial; background-size: initial; background-origin: initial; background-clip: initial; background-position: initial; background-repeat: initial;"><span style="font-size: 8.5pt; font-family: Verdana, sans-serif;">The idea that a small group of relatively junior engineers would have done this on their own is not consistent with how engineers build complex, safety-critical systems.

<p style="margin-bottom: 0.0001pt; background-image: initial; background-attachment: initial; background-size: initial; background-origin: initial; background-clip: initial; background-position: initial; background-repeat: initial;"><span style="font-size: 8.5pt; font-family: Verdana, sans-serif;">The basic engine management software was written by component supplier Bosch. The responsibility for configuring the software for the EA189 engine would have involved a substantial, multi-disciplinary team of engineers at Volkswagen, working with engineers at the supplier Bosch. Before the engines could have gone into production, those engineers and their managers would have reviewed and approved the design and calibration of the engine management systems. They would have also agreed upon, and employed, a systematic testing schedule. This would have involved testing on an engine-only rig, road testing on private grounds as well as testing on public roads.

<p style="margin-bottom: 0.0001pt; background-image: initial; background-attachment: initial; background-size: initial; background-origin: initial; background-clip: initial; background-position: initial; background-repeat: initial;"><span style="font-size: 8.5pt; font-family: Verdana, sans-serif;">The anti-pollution engineers would have handled ensuring that the engine management system was sending appropriate commands to their components and that their hardware was responding appropriately. This kind of exhaustive testing is one of the reasons why developing new vehicle models costs billions of dollars and takes several years.

<p style="margin-bottom: 0.0001pt; background-image: initial; background-attachment: initial; background-size: initial; background-origin: initial; background-clip: initial; background-position: initial; background-repeat: initial;"><span style="font-size: 8.5pt; font-family: Verdana, sans-serif;">One possibility is that a large group of Volkswagen engineers conspired to falsify the written records of this testing.

<p style="margin-bottom: 0.0001pt; background-image: initial; background-attachment: initial; background-size: initial; background-origin: initial; background-clip: initial; background-position: initial; background-repeat: initial;"><span style="font-size: 8.5pt; font-family: Verdana, sans-serif;">An alternative scenario is that accurate written testing records were made, showing that the pollution controls were inoperative in normal driving. These accurate records were reported through normal channels, and the engines went into production anyhow. It is very hard to imagine how either event could have occurred without the influence of senior managers. German newspaper reports indicate Bosch may have informed Volkswagen about the illegality of its plans in 2007, and that senior management were informed about the issue in 2011.

<p style="margin-bottom: 0.0001pt; background-image: initial; background-attachment: initial; background-size: initial; background-origin: initial; background-clip: initial; background-position: initial; background-repeat: initial;"><span style="font-size: 8.5pt; font-family: Verdana, sans-serif;">Rare is the whistleblower

<p style="margin-bottom: 0.0001pt; background-image: initial; background-attachment: initial; background-size: initial; background-origin: initial; background-clip: initial; background-position: initial; background-repeat: initial;"><span style="font-family: Verdana, sans-serif; font-size: 8.5pt;">The responsibility for the decision to deceive the emissions testers will ultimately rest some way up Volkswagen’s management chain. But as well as the senior decision-makers, there is very likely to have been a much larger group of engineers who knew of the illegal deception, understood the consequences and chose not to reveal it to authorities or the media. The lack of whistleblowers from this larger group is striking.

<p style="margin-bottom: 0.0001pt; background-image: initial; background-attachment: initial; background-size: initial; background-origin: initial; background-clip: initial; background-position: initial; background-repeat: initial;"><span style="font-size: 8.5pt; font-family: Verdana, sans-serif;">The ethical duties of software engineers in these circumstances are, theoretically, quite clear. The Software Engineering Code of Ethics, agreed jointly by the Association for Computing Machinery (ACM) Institute of Electrical and Electronics Engineers (IEEE), states that a software engineer <g data-gr-id="1081">should:</g>

<p style="margin-bottom: 0.0001pt; background-image: initial; background-attachment: initial; background-size: initial; background-origin: initial; background-clip: initial; background-position: initial; background-repeat: initial;"><span style="font-size: 8.5pt; font-family: Verdana, sans-serif;"><g data-gr-id="1081">Disclose</g> to appropriate persons or authorities any actual or potential danger to the user, the public, or the environment that they reasonably believe to be associated with software or related documents. While the code also addresses responsibilities to employers, including confidentiality, it makes clear the primacy of the public interest in cases where these ethical duties conflict:

<p style="margin-bottom: 0.0001pt; background-image: initial; background-attachment: initial; background-size: initial; background-origin: initial; background-clip: initial; background-position: initial; background-repeat: initial;"><span style="font-size: 8.5pt; font-family: Verdana, sans-serif;">[…] in all these judgments concern for the health, safety and welfare of the public are primary; that is, “Public Interest” is central to this Code.

<p style="margin-bottom: 0.0001pt; background-image: initial; background-attachment: initial; background-size: initial; background-origin: initial; background-clip: initial; background-position: initial; background-repeat: initial;"><span style="font-size: 8.5pt; font-family: Verdana, sans-serif;">Acting on this professional obligation, when it involves revealing an employer’s unethical practices to regulators or the media, usually imposes a tremendous personal cost. As a consequence, examples of engineers blowing the whistle are very rare.

<p style="margin-bottom: 0.0001pt; background-image: initial; background-attachment: initial; background-size: initial; background-origin: initial; background-clip: initial; background-position: initial; background-repeat: initial;"><span style="font-size: 8.5pt; font-family: Verdana, sans-serif;">Engineer Salvador Castro informed the US Food and Drug Administration (FDA) about a potentially life-threatening flaw in his employer’s infant incubators after his employer did not fix the issue. He was fired and was unable to regain regular employment, despite the flaw being confirmed and a recall notice issued by the FDA.

<p style="margin-bottom: 0.0001pt; background-image: initial; background-attachment: initial; background-size: initial; background-origin: initial; background-clip: initial; background-position: initial; background-repeat: initial;"><span style="font-size: 8.5pt; font-family: Verdana, sans-serif;">As this example illustrates, the incentives for working engineers was keeping quiet, not speaking out.

<p style="margin-bottom: 0.0001pt; background-image: initial; background-attachment: initial; background-size: initial; background-origin: initial; background-clip: initial; background-position: initial; background-repeat: initial;"><span style="font-size: 8.5pt; font-family: Verdana, sans-serif;">Holding individuals accountable

<p style="margin-bottom: 0.0001pt; background-image: initial; background-attachment: initial; background-size: initial; background-origin: initial; background-clip: initial; background-position: initial; background-repeat: initial;"><span style="font-family: Verdana, sans-serif; font-size: 8.5pt;">As time goes on, there will be much interest in whether the most senior decision-makers responsible for the deception at Volkswagen are punished appropriately, given the consequences of their actions. But to concentrate only on decision-makers lets the much larger group who knew something and did nothing off the hook. It’s time to look at the incentives for all engineers to disclose flawed systems that put the public at severe risk to the appropriate authorities (or the media). Firstly, we need to find better ways to protect those whistleblowers that do come forward. But we should go further. We should seriously consider whether those who could, but do not, disclose dangerously flawed systems should, in some circumstances, face some form of sanction.
