I sometimes get requests to create a vector graphic that can be easily used by anyone without having to resort to special skills or software. You can use a vector eps in common programs like MS Word but to actually manipulate a vector file (e.g. change colors, change text, etc) you need to use vector editing software in order to maintain the vector data. Vector software is not commonly used in your average office. There are many vector editing programs including free and open source editors and free online (browser) vector editors you can use.
Vector files can also be exported and saved as common formats like jpg, png, gif, and more, which can be used in common office applications. Jpgs, pngs and gifs are not vector.
