This post might apply more to city style environments.
i live in a town of 1000 people
Walker and work in a place that has 30 or so employees. Now while working on projects, we also have what the client wants, but there is always instances where there are different ways to do it. We have the chance to suggest ideas doing meetings about the projects, and our company is always taking suggestions about work env. etc
..
But the easiest thing to do, is just talk to your supervisor, "Hey, i have an idea about this
...". also, if you want to back it up, its always better to have some good research about what you want. Ive always found that if you want to push something, you have to push it your self, the boss isn't going to help if hes not ready to implement. So information on the subject, maybe a presentation ready, some good resources, and then prepare a speech for what you want.
like any good sales person, you should be able to sell a ketchup Popsicle to a lady in white gloves.
And just remember that they might shoot you down, but I'm sure your opinion will be more valuable the more they find that you always have something worthwhile to investigate.
