VW a lesson in marketing versus regulations

By now you will be very aware of the VW diesel scandal where the software on the car detected when the car was being tested and controlled exhaust emissions to past the test.

Anyone that works in gathering requirements can easily see the problem here. There were two competing requirements Marketing and Regulatory and in the end the marketing side won out.

Big business is a game of cat and mouse. Laws are in place for a lot of things but for business the viewpoint of laws is the risk / cost of being caught and the benefit of not following the law. If the law is not enforced 100%, business will start to think of it as an optional law. There are numerous cases of settlements between car companies and the US government or consumers. The Titanic is a classic example of the law being met but the intent of the law being missed which was to have enough life rafts to save lives – the law had not been written in such a way as to force the life rafts to be enough to meet the number of passengers.

When gathering requirements for a solution, care must be taken to understand the implications of giving one set of requirements higher priority over another. Risk analysis is supposed to be done to ensure the VW, Titanic situation never occurs today. However profit is a powerful master and it will make people blind to that which is obvious.

Double check those requirements that fly in the face of morals to make sure you are not ignoring something that will later make you a headline.


When software kills due to incomplete requirements

If you are lucky, your software has not been responsible for the death of anyone to date. If you are unlucky then you know it.

When a analyst gathers requirements for a piece of software there is a tendency to focus on the happy path and ignore the surrounding paths that can lead to disaster. Unfortunately events can lead up to the identification of the missing requirements and sometimes death is a result.

To be fair, we humans can still kill ourselves without software such as with the mechanical loaded gun or the speeding car taking a bend too fast. However software seems to give people in some cases a false sense of security that does not exist. In other cases it can give them power to do something that should not have been possible if they were directly engaged with the physical which leads to disaster.

The article below refers to two cases where software enabled a pilot to do something they should not have been allowed to do with death being the end result.

Lessons from spaceship two’s crash

In the above article, the situation was different from my previous article about lack of tactile feedback. In both cases the pilots knew what they were doing, they just did it at the wrong time or too frequently for the specific vehicle to survive.

As an analyst, be it a system’s analyst or business analyst, it is not enough to think of just the happy path. Whenever you are gathering requirements you need to also think of what will keep us on the happy path. Whenever there is an interaction or a key data point, ask yourself if the event that causes this can be triggered at the wrong time or occur too many times.

Look for the ways that one can step off of the path and see if you can build either a metaphorical wall to keep us on the path or ways to get us back on the path before any damage is done.
