After you set clear expectations, there are a few steps you can actively take to effectively communicate and manage them.

• Be very clear on the objectives
• Allow time for the employees to ask questions
• Discuss the tools necessary to accomplish each task.

Team expectations refer to the behaviors that occur while working together on tasks. 

• Respect and courtesy to everyone.
• Be accountable for your work.
• Be reasonably flexible about task assignments.
• Be willing to lend a helping hand.

Performance expectations should be measured by the company and communicated by management in order to move toward a specific company goal. 

For each new person joining, set specific and clear employee and performance expectations to encourage accountability.
