Competency defined is the ability to do something successfully or efficiently. It has to do with skill, knowledge and ability. To be competent means to be equipped and made adequate to fulfill God’s calling.
Even as competency is important, competency does not operate in a vacuum. A person may be highly skilled but if he/she is not a man or woman of integrity. It matters little how competent a person is for their lack of integrity will sabotage them and their team. A person may have great skills and knowledge but if they also need to be competent or "skilled" with interpersonal relationships or they can easily shipwreck the team.
Competency is essential but if the competent person does not communicate, cooperate and is not committed to the team the team experiences a slow death.
Grow your competencies to complement your integrity and as a team player. Use your competency to strengthen your team and train them in the 5Cs.(Christ, Community, Character, Calling, Competency) (inspired by Robert E. Quinn, Deep Change - Discovering the Leader Within, chapter 13)
