Careers in software engineering

Choosing software engineering is a smart thing to do if you want to get a well-paid job. A recent survey suggests that 3 out of 4 new science and engineering jobs in the US will be in computing related areas and that 27% of these new jobs will be in software engineering, compared to 16% in all other engineering disciplines put together.

What this means is that, as software engineers, we will have an increasing influence on engineering in general. We therefore have to be prepared to think about systems and not just software and throw off both the blinkered ‘geek in a cubicle’ and the ‘anal process tyrant’ image that is all too often the stereotype for software engineers.

SEMAT and the definition of software engineering

Tom Gilb proposed a definition of software engineering as “Software engineering is the discipline of making software systems deliver the required value to all stakeholders.” This is a seductive definition but when we start to unpick it, we run into problems.

1. Organisations are incredibly diverse. There will inevitably be conflicts and you probably won’t discover most of them until you deliver a system. Furthermore, organisations change – the ‘value’ of a system is not the same on deployment as when it was initially proposed.

2. Many systems are deliberately disruptive. Management want to change ways of working and do so by introducing new software (often ERP systems). The idea is not to deliver value to all stakeholders but to deliver value to the ‘organisation as a whole’ – whatever that is.

3. In some organisations, stakeholders work in a state of creative tension – e.g. doctors and managers in a hospital. As a matter of principle, they will not agree on value.

4. In my experience, getting key stakeholders to engage in discussions about new systems is really hard – they are far too busy doing their jobs. On the other hand, they complain a lot when a system doesn’t do what they want.

Tom’s definition is good because it recognises that simplistic notions of ‘success’ don’t or shouldn’t apply to complex software. But culture and politics  and normal human cussedness mean that it’s really hard to make it work.
