Questions on Resume

Hi Folks, I heard the the show on resume some time recently. (I am new bee to Manager Tools). I have the following questions regarding resume writing. I have faced a number of situations like the following. I work in a team with 2 or 3 members. I have come up with some very good ideas. But there when final product that comes out is not exactly similar to the initial idea proposed. It undergoes a series of changes (thanks to the opinion/ corrections from other members of the team). I really value the suggestion of the team members, but the problem is that there are times when final product comes out it will have a so much of other persons ideas that it will look like his idea completely.I acknowledge others contribution but how do I put it my resume that the product is actually my idea (or I started the product idea) Extending this to the implementation phase(I am software engineer). I would have implemented a particular system for the project, but the system might be ultimately discarded when the final product is out. How do I mention these in my resume. I am also on the other side of the road many times. Like, I have given suggestions to a project and it finally succeed. How do I take credit for the same without taking too much off the person who came up the initial idea. Thanks Sundar Rajan G S
