Why do successful innovation requires input from all departments within a firm , not just the reserch and development department?

I think that when we go from company to company, it is essential to ask the fist starter questions like who you are and what brought you here. As an on-line interprenuer, I am also learning and discovering that no what where I opt in to apply or just check it out. The first thing they want to know is your demographics. Because we are dealing with public and private companies that are into the network of on-line marketing. I think for safety measures this protects us. However some have personal and private sites that sure don't need public awareness! I am affiliated with Social Networking sites and that is just one leverage gain to my advatantage. " I THINK" In knowing who what we are looking for and who are audience targets are. This is what I do to cover myself. Always ask Questions. There is a lot of regualtions to follow, but a woman like me needs it just simple, precise and right to the point. Because of many scammers and hijackers out there. By logging into your group discussions, you will learn that there are people out there to do a crime that it not fair to those who equally pay their share for services and results. To me, I am just learning but as it is for some new or in the game way before us new folks. I make the attempt to ask them first. It's better to know now that to regret later on. Don't you think?
