Fill your resume with "PAR" statements. PAR stands for Problem-Action-Results; in other words, first you state the problem that existed in your workplace, then you describe what you did about it, and finally you point out the beneficial results。 (来源:http://www.dianziku.com)
Here's an example: "Transformed a disorganized, inefficient warehouse into a smooth-running operation by totally redesigning the layout; this saved the company thousands of dollars in recovered stock."
Another example: "Improved an engineering company's obsolete filing system by developing a simple but sophisticated functional-coding system. This saved time and money by recovering valuable, previously lost, project records."
