Startups can be crazy, exciting places to work. While it can often feel like there are more balls in the air than hands to catch them, somehow everything ends up getting done. This is because, many times in startups, people from one department jump into another department to tackle the tasks at hand.
The collaborative, hands-on nature of startups is a great example of cross-functionality at work. Cross-functional teams combine the strengths and talents of different individuals to reach a common goal. Applied to customer service, cross-functional support means uniting individuals from several different departments (marketing, sales, operations, etc.) to figure out how to provide the best service possible to customers.
