No matter how good anyone is at what they do, an inability to communicate effectively can hamper the success of any endeavor or undertaking. There are different personality types and some work well together than others at reaching an end goal. In an office environment, it is essential that everyone communicates well enough so that there are less mistakes occurring in accomplishing what needs to be done to achieve successful results. Effective communication doesn't just apply inter-office. It is essential that there is a good communication flow with people outside the company as well which includes correspondence with clients, vendors, suppliers, and any others in the business network.
