If you read my blog entry on Language Specialization you might have concluded that I prefer generalists. If, in our industry, generalists were what the definition describes, then I would prefer generalists. Unfortunately, business software developers seem to have created their own definition of generalist.
generalist: a person competent in several different fields or activities
business software developing generalist: I know how to do the simplest tasks with many different languages/tools, but I can not be considered competent with any of them.I blame Scott Ambler. To me anyway, it seems like the daft generalist movement started when Scott wrote Generalizing Specialists.
Our industry has always been saturated by bad programmers. I'm on record stating that at least 50% of the people writing business software should find a new profession. The problem with bad developers is that they take good ideas and turn them in to monstrosities.
I remember reading Generalizing Specialists and being inspired. I thought Scott gave fantastic and relevant advice. Unfortunately, many bad or junior developers heard: Don't bother to deeply understand anything, instead, you're agile if you know a little about everything. Suddenly, when I started interviewing developers I ran into situations like this.
- me: So, I see you have Erlang on your resume, how do you like the language?
- candidate: I like it's concurrency handling, but I'm a bit weary of it's syntax.
- me: (thinking - okay, do you have any original thoughts on Erlang?) I can understand those points of view, what problem were you trying to solve with Erlang and why did you think it was the right tool?
- candidate: Oh, I really only got through the 2 minute tutorial, you know, hello world basically. But if you guys have Erlang projects you want me to work on I'm happy to, I'm a generalist, I like all languages.
- me: Okay, so what language would you say you know the most about?
- candidate: I don't bother to specialize, I do a little bit with each language, you know, hello world or whatever, so I can use the right tool for the job. That's the best part of being a generalist.
- me: (thinking - this interview is already over) Okay, so tell me about the languages/tools you've had to use at your different jobs?
The truth is, these generalists have little in the way of valuable knowledge. They provide their projects with little more knowledge than a Google search can bestow in 30 minutes. In short, they're worthless, if not destructive.
I don't actually blame Scott Ambler. In my opinion he was right then, and he's right now. Become a Generalizing Specialist is still the advice that I currently give developers.
Becoming a Generalizing Specialist takes time, but the first step is becoming a Specialist. Once you deeply understand one language/tool, you can move on to the next relevant language/tool. How do you know when it's time to move on? When you start having answers to questions that people aren't asking. If you're constantly looking up answers to common questions, you aren't a specialist. However, if you start providing more (relevant) detail in your answers than people are looking for, you're on your way to possessing the deep understanding that a Specialist should have. At that point, it's probably time to start looking deeply into something else.
Eventually, you become competent with several different tools and languages. You've become a Generalizing Specialist and as such you are significantly more valuable to your team.
