text: Getting multiple opinion also helps make progress. For example, if a company is making a new phone for the elders, they could ask the elders to use their new product and hear what is a good option or a good option to add and what is a option that they don't need. When I made a small car, I asked my parents to see it and tell me things that I have to fix or add more. After hearing all the opinions I made changes to make the car look better.
