As a project manager, you've noticed that one of your team members, Sarah, consistently makes sound decisions and delivers high-quality work. You're considering giving her more decision-making authority within her area of expertise. What is the best approach to take in this situation?
Increase Sarah's decision-making authority only after she has completed additional training
Do not increase Sarah's decision-making authority to avoid potential conflicts with other team members
Give Sarah complete autonomy in her decision-making within her area of expertise immediately
Gradually increase Sarah's decision-making authority within her area of expertise while providing guidance and support
