A large number of companies nowadays use matrix-style organizational structures. Organizational structure has a huge impact on the performance of a company, so choosing this style is not a matter of convenience, but rather the fact that matrix organizations have been shown many times to be effective. Although I have not ever been a corporate employee, it stands to reason that most companies will choose methods that have been tested and proven to work, which is why the matrix structure is so popular.

Personally, however, I would prefer to work in a functional organization. This is largely because I would rather have a singular boss, and use my own initiative to work with and learn from employees of different teams if need be. Of course, this is purely a matter of personal preference- different personalities will doubtlessly prefer certain organizational structures. Because, as mentioned previously, many functional managers do not have technical expertise in the area the team is working in, a number of people (including possibly myself in the future) may well dislike this structure.
