We can work on the efficient way after justifying with proper reason to the experienced associate.
Step-by-step explanation:
Though the question is incomplete, I can understand what is actually expected and then providing solution from my point of view.
When you feel that your idea is better,
- Calm down yourself to prepare for conversation
 - Place a request to the experienced associate to hear your view
 
- Justify how your way is better than the view of experienced associate
 - Make sure that you do not dominate and give respect to his / her age
 - Be prepared for the cross question raised by the associate
 - Convey about the outcome achieved clearly
 - Use the right vocabulary
 - Be strong in what you want to convey and the same should not lead to conflict
