In most professional lives, the pinnacle of ones career comes with acknowledging exceptional work. Awards were created to help perpetuate that rationale. They are an effective method of immortalizing a person in the business world. Whether this professional achievement stays on the mantle at home, or in the company's main foyer, it's important to be prepared.
What's more important than being prepared? Being sincere. Thanking people in a monotone is not winning you any points on the professionalism scale, especially when awards are presented in front of your peers. If you hate your place of employment, consider your awards acceptance speech an audition to other company's of your poise and professionalism.
Thank the people who nominated you. In the cutthroat world of business, awards and accolades don't grow on trees. In most cases, someone (or some people) probably had to "pitch" an idea, in the form of a letter or nomination ballot as to why you deserve the victory. Don't leave these people out in the cold. It makes for an unpleasant work atmosphere if you do so.
Think of any type of positive influences you may have had along the way, and thank them too. It could be family, encouraging friends, peers, a significant other or even a mentor who wasn't afraid to tell you when you screwed up. These types of bonding relationships are often one-sided, and while the learning is invaluable, sometimes the best payoff for the mentors is knowing they've had a hand in your success.
A little modesty goes a long way. Winning a prestigious award is certainly just cause for celebration. Yes, you may be elated to hear your name called. Yes, that major account ruined your life for six-months, but there's no need to stand on the table screaming, "I'm the King of the World!" Of course you may feel that way on the inside, but think of all the potential clients/trade professionals that may be watching.
The company/organization throwing the show deserves a thank-you. Try to refrain from stating everything you know about the company; " and then I turned 5." Instead, go for a gracious sentiment such as "I'd like to thank (name of company/organization) for their generosity."
Add a little humor. If the mood is right, there's certainly nothing wrong with adding a funny anecdote to your acceptance speech. If your speech is part of a series of speeches a la awards banquet, then it's a great idea to make yourself stand out lighten up the tone.
Time is of the essence. If your award is presented as part of a long evening, keep your speech at a two-minute maximum. Generally, two minutes is enough time to thank everyone and mention some key points. If you're the guest of honor, or accepting a lifetime achievement award, then time frame no longer becomes a factor. You have carte blanche to speak as long as you like you deserve it!
Enjoy it. Much effort is put forth in what to say, how to say it, which is great, but what's better? Stopping to smell the roses. Enjoy the event, and let the nerves go to someone whose ill prepared.
