When your company lacks experience in tools and techniques that can make it more productive, your company has knowledge debt.
Companies tend to operate in ways that exacerbate their knowledge debt problem. Consider this fairly typical job ad:
Initech is seeking an experienced Software Engineer to join
the engineering team.
* Design core, back-end software components
* Analyze and improve efficiency, scalability, and stability
of various system resources
* M.S. Computer Science or related field preferred
* 2+ years of Java experience
* Expert in relational data modeling and query
optimization using MySQL
I would posit a guess that this company uses Java for the majority of its work and uses MySQL on the back-end. Naturally, the company wants to recruit people who share that skill set and can "jump right in" and contribute.
This mindset is fundamentally flawed. A company should be hiring for problem solving skills, programming ability, and cultural fit, not for any specific skill set.
If anything, a company should prefer candidates who are experienced in a different set of technologies. Any worthwhile programmer will be able to pick up the technologies necessary to work with the existing code base. Hiring people with different skill sets gives the team instant experience in a new set of tools for solving problems.
