Which is important to become successful in job?

In all honesty I must say a good communicator stands a better chance of being successful on the job.

No doubt knowledge helps but knowledge alone does not help. Communication is essential.

Think about this: A fresher is chosen for a job typically in the first 3 minutes of an interview... it's not the knowledge that is tested in 3 minutes, but overall 'ability' to communicate. Also, you might be the best student of the Univeristy, but if you cannot communicate how you bridge your existing learning to the Corporate world... you'll not end up getting the best job, for sure!

We can always communicate that we don't know and therefore by asking the right questions, come to know!

i think both r equally important

Honestly, both.

Communication in the way of self promotion

To be successful, knowledge is a must but unless one has communication skill, people can not recognise the availability of knowledge. It is quite important how one expresses his/her knowledge to the people who matters say customers, superior etc. Thus communication skill is also equally important.

It is often said that teachers learn from their students ; when you try to explain a subject to anotherperson , you find that things which you yourself had taken for granted , are not so self-explanatory , and it requires a lot of thinking on your part to explain everything so that it is clear to the other person.

Thus , the act of communication , makes you more enlightened.

Thus , there have been several physicists of Nobel prize winning repute , but there have been very few who have been able to explain modern physics in a clear , understandable manner. One such is Richard Feynman. A popular author of science , especially physics is Isaac Asimov.

On the job , one of the greatest abilities a person can have is the ability to convince others ; almost all of this can be attributed to communication skills.

In fact in the days of the ancient Greeks , one of the ways to knowledge was by engaging people in dialogue ; discussing things with others , brought in new ideas or helped clarify unclear ones. The most famous exponent of this was Socrates , from whom we have the Socratic dialogues.

There are various barriers exist at the workplace. Predominant are language barrier, cultural barriers , communication barriers etc. Adequate knowledge that a person possesses, needs to be translated into action through communication. Once an effective communication is established whatsoever, the difficult task may be assigned. Its always seen performed/completed. To be successful in job, you need to be a performer. To be a good performer you need to communicate the goal,aim & action etc clearly so that the executor carry out the task completely.
