If you write a strong foundational resume that shines the spotlight on your accomplishments, leadership style and the solutions you bring to the table then you should only need one resume that you can edit and tweak.  When you have a strong foundational resume, you shouldn't need various iterations. You may need to tweak a well-written resume here and there, but that should be the extent of editing it needs.  Additionally, it is important every resume tweak you do is in alignment with your LinkedIn profile, which is a static document.  Multiple versions of your resume means some won't be in alignment with your LinkedIn profile, and we don't want that for you.
