If you do a great job analyzing numbers but nobody realizes it, are you really doing a great job? Let's face it; a good analysis is good, regardless of how it came about. That said, every analyst has a dual-objective: to create great analyses and to make sure people know you're responsible for the analyses.
I realize there's no "I" in "team," but you deserve credit for the great work that you do. I wrote recently about how difficult it is for most people in the organization to even explain what makes their Business Systems Analysts (BSA) so valuable--so if often goes overlooked. However, even if you've cultivated the ability to actually articulate the value that you bring to the organization, you should never miss an opportunity to market your value.
The concept is so important, I came up with a term for it--analytic magniloquence. I raised this topic in "Super Analysts: A New Generation of Competitive Distinction (see http://dellworld.com/liveonline/#!resources-asset-whitepaper-super-analysts-new-generation-competitive-distinction-041913) because the hallmark of remarkable analysts is their ability to unabashedly tout their own talents. Magniloquence is often associated with bombastic behavior--a very overt and over-the-top approach. Although it usually carries a negative connotation, for most analysts, it's a good direction traverse. Analysts tend to be reserved--it's part of their nature. Most of their daily dialog happens inside their own head. There's nothing inherently wrong with that--you don't want everything in your head coming out of your mouth. However, you must do and say enough to be recognized for your great work. If you shoot for magniloquence you'll probably end up where you need to be. Even if you over-correct, it's not necessarily a bad thing.
Talking to Strangers
There are overt and subtle ways to brag about your talents. Openly taking credit for all your good deeds can be uncomfortable, and if not handled properly, it can backfire on you. However, subtly announcing your skills is always effective. You should practice taking credit without feeling bad, at every chance you get.
Remember, your name is more than a legal way to identify yourself--it's your brand. When people say your name, what image comes to mind? Are you just some person in IT or are you that great analyst they can always depend on? Try to attach your name to anything that's significant and widely recognized. For instance, if you've created a dashboard that everyone uses, try to get your name associated with it. When I helped Pacific Gas and Electric upgrade their Geographic Information System (GIS), I noticed that the GIS homepage (which is constantly seen by almost everyone in the company) clearly listed two names to contact for assistance. It came as no surprise, when I surveyed all the users for who they thought were the GIS experts--these two names came way up on top.
Also, get comfortable with presenting. Even if you're presenting someone else's work, the audience will associate you as the authority on the topic of the presentation. The advantage for analysts, who don't have a problem presenting--or even public speaking--in front of an audience, is they usually get more credit than their peers. Be careful though. Presenting, even if it's for a small intimate group of friends, carries some risk. A poorly-executed presentation can do more harm than good to your personal brand, so make sure you polish your skills before jumping out there. You might even join a group like Toastmasters; it's a great place for beginners to practice before it counts.
Understanding and explaining your value is a great first step; however, if you don't make the right impression on others, it won't matter much. Be diligent about your analytic magniloquence. Never miss an opportunity to associate your name with a great piece of work, and get out there and talk to people. Whether it's an informal conversation in the break room or a town hall filled with people, never shy away from the opportunity to tell people what you've done and what the result was. I can guarantee you, if you don't take credit for your own great work--someone else will.
