Before implementing a big change, ask others for feedback. People who will be directly affected by your proposal will have serious concerns. Take their opinions seriously. With a few minor adjustments, you could hit upon a compromise that satisfies everyone. Although you don't like the idea of going back to the drawing board, you should do so anyway. Clinging stubbornly to your way will cause anger and resentment. It's better to bend than to break, especially where colleagues are concerned.
