In most companies, that's what IT is: doing the necessary stuffs to support business. On the other hand, it's their decision to specialize in such technology. Perhaps they have the necessary business knowledge and they just need to compliment that with enough IT skills. Please don't act like a jerk by calling them one-trick pony. There are reasons before one came to make a decision, be it quality time with family, or piece of mind, or just to get by in life and do other things outside work. I met tons of super-ego developers who always try to keep up with the latest greatest ORM tools in different languages praising the latest technology as the "best one out there" every 2 years. They did this for their on satisfaction, not for delivering any meaningful values. I also met "one-language per year" developers who don't know low-level OS, or how computer networks work. I met developers who know how to write code but don't know how to perform capacity planning, security audit, or heck, even write proper unit-testing, integration-testing, and acceptance testing. I met developers who write code according to his/her "raw talent" (you know them developers, they're smart, but they can't work well with other people. Don't even bother touching their complex code). People come in various experience and background. Don't make generalize judgement. Some people decided to improve their skills once every 2 years, be it learning a new programming languages or a new web-me-too-framework. To others, that's like a rat-race. By the time these developers reached 40 years old, they have learned 20 different programming languages yet they don't understand the business inside-out. They deliver great architecture yet it's not what the business need. What's that called? one-trick pony?
