what is system skill?

Answer 1

From Wikipedia:

Skills Management is the practice of understanding, developing and deploying people and their skills. Well-implemented skills management should identify the skills that job roles require, the skills of individual employees, and any gap between the two.

The skills involved can be defined by the organization concerned, or by third party institutions. They are usually defined in terms of a skills framework, also known as a competency framework or skills matrix. This consists of a list of skills, and a grading system, with a definition of what it means to be at particular level for a given skill. (For an example of a mature skills framework, see the Skills Framework for the Information Age, [1], a technical IT skills framework owned by a British not-for-profit organization.)

To be most useful, skills management needs to be conducted as an ongoing process, with individuals assessing and updating their recorded skill sets regularly. These updates should occur at least as frequently as employees' regular line manager reviews, and certainly when their skill sets have changed.

Skills management systems record the results of this process in a database, and allow analysis of the data.

Good Luck....
