They’re not always taken in to production. I recently had a part nearly get all the way and get cancelled because it wasn’t quite the right time to be doing it. But your ideas always get treated seriously and you get a chance to explain them and convince people they are good ideas.
I think my ideas are always considered – they might not always be accepted if there is an aspect that there is another way that is more appropriate / better to use. Myself and my colleagues work as part of a team and so a lot of ideas are discussed before going forward with one.
