Now imagine you’re on the receiving end.

We’ve been talking (well, posting and commenting) about how to prepare for and conduct conversations, both those that are difficult and those that should be easy.

Easy or difficult, if you’re on the giving end you have one clear advantage: You get to prepare. If you’re on the receiving end your ability to prepare is limited, even if the deliverer has scheduled the conversation and stated the subject clearly.

Mostly, it’s as if the other person is doing stand-up while you’re performing involuntary improv. How can you prepare when you aren’t in a position to prepare?

Answer: Start preparing right now. No, you can’t prepare for the specifics. Yes, you can be prepared with broad strategies you’ve spent time mentally rehearsing.

Start with the broadest strategy of all. That’s your so-called “personal brand” — your image and how you project it.

My own personal brand (no secrets here!) is “relaxed and confident.” If I’m caught off-guard, that’s what I retreat to … not as well and reliably as I’d like, but it’s what I shoot for.

Your brand might very well be different: Young and brash, smooth and suave, quietly competent, bold and intimidating … the specifics matter less than making how you want to come across in all situations a conscious decision.

This means more than recognizing the advantages to be gained from those around you perceiving you this way. It also means accepting that the image you project might not always be advantageous, but that’s how you have to present yourself anyway.

Because you don’t get to be situational about this. Sure, you’re allowed moods. But being a completely different person depending on who you’re talking to and about what is more likely to make you come across as a complete phony (or victim of dissociative identity disorder) than anything else.

And in case you think planning at this level is the hallmark of a complete phony, I disagree. There’s no reason the image you project should be a one-to-one reflection of your self-image. But there’s every reason you should do everything you can to make your projected image real — for your self-image to become your projected one, so that you make yourself into who you want to be.

Know who you want to be. That’s how you should behave no matter the situation you’re faced with.

Start with the easiest: Your manager compliments you publicly for a job well done. Hey, it could happen! It happens all the time.

How do you handle public compliments? No, don’t tell me. Ask yourself the best way to handle them. Pay attention to how other people handle them, both those who are awkward and those who are graceful. If you know in advance how you’d like to behave in this situation you’ll be graceful about it.

How about the other extreme. Say your manager sits you down for a corrective action talk when you’ve been thinking your performance has been just fine and dandy.

It’s out of the blue and entirely unexpected. You say … what, and in what tone of voice?

A primal scream is out of the question. So is bursting into tears, as neither one is likely to fit your personal brand.

What’s the right answer? Quick — you have no more than three seconds before your silence will be your response.

The right answer is to buy time. As Relaxed-and-Confident Guy, I might ask, calmly, for some of the specifics that have created my manager’s perception.

Young-and-Brash woman might, with a level of animation that doesn’t cross over into hostility, say something like, “I’m not entirely surprised this has become an issue, but I am surprised they (whoever they are) decided to involve you. Tell me what you heard.”

Beyond this I’ll give you one guideline that will stand you in good stead no matter what difficult conversation you’re on the receiving end of. That’s to choose phrasing that makes you and the other person “we,” in a situation the two of you will have to collaborate to resolve.

It can make the difference between you being perceived as argumentative and defensive and the other person wondering why this conversation needed to happen.

Even better, it will invalidate the other person’s plan, which puts you on a more even footing.

Now, you’re both doing improv.

The usual guides to difficult conversations (like this one from HBR) all provide useful tips. What they don’t do is help you figure out what matters most in preparing for them.

What I mean: The usual guides to difficult conversations are all about subject matter, style, knowing your goals, and planning. Most of the guides I’ve run across are intended to help managers communicate better with the people who report to them.

Which isn’t a bad thing, but they’re missing three of the four points of the management compass: your peers, your service recipients (not “internal customers”), and, most important of all, those who sit above you in the corporate hierarchy.

Because they’re focused solely on those you have power over while ignoring those who have power over you, these field guides to management miss two of the most critical differentiators between utter failure and all of the other possible outcomes.

The first is to know your interlocutor.

If you’ll be talking with someone who sweats the details, be prepared to dive in deep. If you’ll be talking with someone who doesn’t sweat the details but does appreciate their importance, focus more on the big picture while preparing to expose just enough of the details to reassure your audience that you have the details covered.

In either case, whatever the difficult subject is you need to cover, plan the conversation so you transition from problem to solution as quickly as you can without creating the impression you’re trying to avoid discussing the problem. You want to make sure the other party understands the problem well enough that your proposed solution is a logical response.

And if you’ll be dealing with someone who sees only the big picture, having neither interest in the details nor an appreciation of their importance? Figure out a big-picture view of the problem and your solution, and stick to them just as well as you can.

Unless, that is, you’re in a negotiation, at which point the details are what justify your estimate of the cost.

Which brings us to another dimension of knowing the person you’ll be talking with: their temperament. You can’t plan a difficult conversation without having a pretty good bead on the other person’s disposition.

If you’re talking with a big-picture executive who is nonetheless patient, you can get away with one of my favorite threats: “You can either trust me on this, or I can explain it to you.”

If, on the other, more common hand, you’re dealing with someone who prefers the view from 100,000 feet and is known for volatility besides, prepare yourself for a blow-up, and know exactly how you’ll handle it when it happens.

How you’ll handle it is first and foremost to be unsurprised. When the person you’re talking with loses his or her cool, if you’re caught off guard nothing good will come of it. If, instead, you’re expecting it you’ll know that now is the time to stay calm and to project calm. In a confrontation between volatile and calm, calm wins every time unless projectile weapons are involved, and if they are, calm is still your best choice.

How you’ll also handle it is to not interrupt. Instead, take notes ostentatiously, making the point with your non-verbals that you’re taking your counterpart’s shouting points at face value; also that you’re entirely unaffected by such an emotive display.

And, if and when your volcanic colleague runs out of steam, summarize. “Here’s what I understand your concerns to be,” you might begin before bulleting them out. “At some point, in order to resolve the situation, we are going to have to dive into the details. Would you like me to schedule another meeting so we can do this?”

This isn’t, I want to emphasize, the only way to deal with a hothead. While a bit riskier you might also choose to hold up your hand (a useful alternative to interrupting) and, when you have the floor, to suggest that when the other person is ready for a more businesslike conversation he/she should contact you and you’ll be happy to pick up where you left off.

The point here isn’t what the right preparation is. It’s to emphasize the importance of being prepared.

Which brings up one more aspect of preparing for a difficult interaction — to have an exit strategy. The more you expect the conversation to turn into a confrontation and the confrontation to become explosive, the more important it is to have a pre-planned way to cut the interaction short.

This doesn’t have to be anything more than having a “hard stop” because of another meeting you have to attend.

And you thought meetings have no business value.
