Why is effective communication important in business?

Answer

Effective communication is important to maintain coordination between central office and satellite offices. That's why modern phone system like the Virtual PBX is equipped with features necessary for on time delivery of products and services and unifying all the communication devices of the business.
Without effective communication none of the businesses departments, customers, or indeed Employers, would be able to get the answers they need in the form they need it. Take for example a phone - great for arranging things, clarifying them, but not great for conducting actual interviews.

Effective communication ensures things run smoothly. You wouldn't run all the way home just to tell whoever happens to be there at the time that you've forgotten your lunch and could they please put it in the fridge. You would phone, or send an email.
