Great to have such a member in your project team. Competina is used to work autonomously and makes the decisions concerning her area of competence on her own.
When she promises to do a task you can consider it done, without the shadow of a doubt. She is extremely efficient and can tackle an enormous workload.
She is friendly but very straightforward and doesn’t beat about the bush. Not everybody likes her direct and rather undiplomatic approach, but as she remains friendly and focused on the task at hand, the colleagues do not hold a grudge against her.
What Competina dislikes most is being told how to do things. She will tell such colleagues in a friendly but quite clearly manner, that they’d better mind their own business.
In case you let her do her work and show that you have confidence, she feels you respect her work and will be the best team member you ever had.
