Communication skills
The ability to give and receive information - both verbally and in writing - that is clear, well-structured and targeted to the intended audience.
Communication skills also include listening and questioning skills as well as non-verbal communication, such as eye-contact, body language and pace and tone of voice.
Interpersonal skills
The ability to relate to and get along with others, build trust, empathise and see things from different perspectives.
Interpersonal skills refer to the broader set of skills of which communication is key but also include social and emotional skills.
Effective communication and interpersonal skills underpin everything, whether in the workplace or elsewhere. Poor communication in a work environment can lead to misunderstandings, time being wasted or mistakes being made, all of which have the potential to be very costly to an organisation.
In any working environment, you will work or liaise with others to at least some degree, whether these people are internal or external to your organisation. The ability to get along with others, put them at ease and win their trust and confidence is vital for the success of the organisation you are representing.
