Your CV shouldn't read like a job description, it should outline your key achievements for each job/position you held, starting your sentences with words like Sucessfully, Improved, Increased, managed etc. If you think of your achievements in terms of:

Problem/Situation
Action (the action you took)
Result (what was the result of the action you took, for example: "...preventing delays to X"). If you can quantify it, then thats even better.

Also, if your not applying through an agency, and your not already doing so, tailor your CV to the job your applying to. Sometimes I try to use the wording in their job description in my CV (in case they are looking for buzz words) with an example from my own work experience.

Hope that helps!

Good luck
