We all know that companies tend to specialize. You want a really good submarine sandwich you go to Subway. You want great chicken you go to Church's Chicken etc.
When it comes to business to business, we tend to hire our suppliers the same way. A company that has the word "production" in its' title, or "radio" in its' title specializes in those areas.
