After you've answered your guiding question and come up with your own conclusions, you have to share what you've learned with others. How you do this can make the difference between getting a promotion and getting fired. Ok, that's maybe a little extreme (unless you yell at your boss that he's targeting the wrong audience and he sucks), but you get the point. Effective communication skills can really help others to see things from your point of view.
So, if your research is good, from reliable sources and draws strong conclusions AND you present these conclusions in a clear and effective way, then you are more likely to receive praise and respect from your coworkers, and maybe even that promotion from your boss!
