Resume writing can be considered more art than science, because its primary function is to create a positive impression on an individual with subjective views; meaning, there are no rules to follow per se, but rather all writing should simply be designed to solicit a positive reaction in the narrowly construed set of individuals that may be reviewing resumes for a given position.
People are most successful when writing a resume when they develop a very clear idea of audience. What would a hiring manager or recruiter for that particular job most desire in a candidate? How can you make your job function and accomplishments align exactly to the position to which you are applying? When distributing your resume, you should feel more like an archer than a mailman: deliver exactly what a very specific audience wants, don't blindly send out your resume to a number of jobs and expect a positive response.
A properly written resume, targeted to a specific job function and group of individuals, is your most powerful tool in job search. Because your resume is so important, it may be advisable to solicit the advice of a trusted and tenured professional in your desired industry or to consult with a professional resume writer.
