If you are an inside consultant or you are a member of the system at the same level of functioning, there may be people who would resent or resist if you state it as your proposal. So you have to frame it appropriately. It's not a proposal coming
I would like to point out that discussions where antagonistic positions are being presented are the life blood of any organization if they are done in a particular context. That context is that you establish a frame around the whole process of argument, so that the disputes, the discussions of antagonistic proposals, are simply different ways of achieving the same outcome that all members agree upon.
Let me give a content example. George and Harry are co-owners of a corporation; each owns fifty percent of the stock. I've been brought in as a corporate consultant. Harry says the following: "We've got to expand. You grow or you die. And specifically we've got to open offices in Atlanta, Chattanooga, and Miami this year." And George over here says "Look, you know as well as I do, Harry, that last year when we opened the Chicago and Milwaukee offices, we opened them on a shoestring. And as a matter of fact, they still are not yet self-sufficient. They are still not stabilized to the point that they are turning over the amount of business that gives me the confidence to know that we can go ahead and expand into these other offices. Now how many times do we have to go through this?"
So there's a content difference between these two human beings about the next thing they should do as a corporate entity. One strategy that always works effectively in this situation is to reframe the two responses that they are offering as alternative ways of getting an outcome that they both agree is desirable. So first you have to find the common goal—establish a frame. Then you instruct them in how to dispute each other's proposals effectively, because now both proposals are examples of how to achieve the same outcome that they both have agreed upon.
So I would do something like the following: "Look, let me interrupt you for a moment. I just want to make sure that I understand you both. Harry, you want to expand because you want the corporation to grow and realize more income, right?" I then turn to George and say "My understanding is that your objection to the expansion at the moment, and your focusing on the fact that the Milwaukee and Chicago offices are not quite self-sufficient yet, is your way of being sure that the quality of the services that you offer as a corporation are of a certain level. You are offering a quality product and you want to maintain that quality, because otherwise the whole thing won't work anyway." And he'll say "Of course. Why do you ask these things?" And then I say "OK, I think I understand now. Both of you agree that what you want to do is expand at a rate congruent with maintaining the high quality of services your corporation offers." And they'll both say "Of course." You've now achieved the agreement that you need; you've now got the frame. You say "Good. Since we agree on the outcome that we're all working toward, let's find the most effective, efficient way to get that outcome. Now you, George, make a specific, detailed proposal about how you will know when the Chicago and Milwaukee offices are stabilized at a quality of operation that allows you to feel comfortable about turning resources elsewhere to continue expanding. Harry, I want you to come up with the specific evidence that you can use to know when it is appropriate to open new branches. What will you see or hear that's going to allow you to know that it is now appropriate to open a new office in Chattanooga, and still maintain the quality of the services you're going to offer?"
