Action Verbs are descriptive verbs that are used to express skills, experience, accomplishments and job functions.

Action verbs such as 'managed', 'sell' and 'programmed' are preferred over non-descriptive action verbs.

It's always a good idea to begin each section of a CV or resume with a strong action verb, for example:

Managing the office stationary requirements was an integral part of my role within the company

An important part of my role was to manage the office stationary requirements.

The Action Verb means the job function, and is a description of the job, "managing".
