Judith possess Competence . It is the quality or state of having sufficient knowledge, judgment, skill, or strength (as for a particular duty or in a particular respect)

Competence is the collection of observable traits and abilities that support and enhance a job's effectiveness or performance. The word "competence" initially surfaced as a notion for performance motivation in a 1959 article written by R.W. White. The phrase gained popularity after David McClelland published a groundbreaking paper in 1973 titled "Testing for Competence Rather Than for Intelligence." All the relevant knowledge, skills, abilities, and traits that go into a person's work are included in their set of competencies. This group of context-specific traits is associated with greater job performance and can be used as a benchmark for measuring job performance as well as for employee development, recruitment, and hiring. Strategic strength is a key competency of an organisation. Employees are better able to know what they need to be effective when skills inside the organisation are established.
