Swimming through the ambiguity

I've just completed my first month of employment at my new job. So far my initial impressions are mixed. There are alot of good and mediocre things about this company. First, I very much enjoy the entreprenuerial culture that exists here. This is a small and growing company and opportunities abound. But at the same time there is a drag in efficiency and a potential lack of direction. We are, for example, very good at launching innovative new products. But, however, we don't do a good job of managing them once they are in the market. So instead of milking product X for all of its profit potential it languishes in uncertainty because the attention has been turned to the next thing.
Anyways, back to me. From the get go my job was very ambiguous. I was told that I would be the sales/marketing analyst. Beyond that, my job description was anyones guess. This is the first such position at Xyron so there is no precedent or procedure. So my first month has been spent, not only trying to become familar with the company and its culture, it has also been spent trying to create goals and provide structure to my position. I am starting to get a good grasp on the business, the next few weeks will tell if I will be able to truly structure my position to the point where I can really add value to the company.
But in the end it all comes down to me and how proactive I am. Excelling at these qualities, I have found, seperates the wheat from the chaff.
