To be the best...

What are the top 3 traits or skills every technical writer must have to excel?

Can you suggest any tips or insights to develop your technical writer expertise?

Interesting question. For me it's:
1. You have to have an avid interest in all aspects of technical writing: the formatting, the attention to detail, knowing your audience, and English (or whatever language in which you are writing).
2. An ability to interview subject matter experts. Not just sending them an e-mail message asking for facts and figures, but going out and meeting them face to face and getting the information and finding out what they do.
3. An ability to get things done on time. The deadlines baby, the deadlines! In this racket, deadlines are everything. If you can't meet them without all sorts of all-nighters and other ass busting, you are in the wrong game and will soon learn to hate it. To do it, you have to be able to work under some stress.

Art,
Your 1 & 3 answers are great and most technical people would easily see them, but, I'll admit I was a little surprised to see your #2. I don't typically think of Technical Writers as being good at face to face interactions. I suppose it could be a really beneficial skill, though, couldn't it?

Sorry to barge in... But I agree with Art.

At least, it was this skill that allowed me to sell my rates which were typically around 30% higher than average... It is an absolute advantage in the more technical areas. I have once written a book on radar testing equipment for a major player in European market, and interfacing with their engineering department was the most challenging, yet rewarding, part of that job.

I'd say that answers 1 and 3 are what every technical writer ought to have, and answer 2 is a nice bonus which will have a substantial impact on rates.

Being a team player is the most important. Attitude, attitude, attitude! Let me say it again.... ATTITUDE! Attitude makes up for inexperience. Technical skills can be learned, but attitude is ingrained.

I agree with all of the above,
but the top requirement should be good writing skills!!!

I agree with Art. The ability to interview your subject matter experts and to get along with them is essential.

Actually, it is often quite critical. Your ability to manage interviews extends from the initial job interview to researching the needs of the project and the user. Good skills in this case get you the job and help you produce the best documentation possible.

I would add that an ability to write is critical. It's not just having the correct grammar, sentence structure, and punctuation. To be an effective writer, you must be able to choose the right words and arrange them so that your writing is clear, concise, and easy to understand.
The documents you produce must also be clear, concise, and easy to understand. A good understanding of the principles of information mapping helps with this.

Art is right on all three counts if you want to be a well rounded writer. However, Ed hits the bullseye with the primary skill. I have worked with Tech Writers who considered themselves to be "very good" . . . and have had to redo their work!
