I've recently received questions from a few clients about whether or not they should include recommendations from colleagues on their resume. I understand the thinking behind the idea; it seems like it would be really effective to include positive quotes and brief recommendations on your resume. In practice, including quotes and recommendations on your resume is not a very effective approach.
The main reason this doesn't work as well as it seems it should is that these quotes and recommendations are unverifiable. There is no way to quickly verify that the quotes and recommendations you include on your resume are real. In contrast, a letter of recommendation is generally written on an organization's letterhead. Recommendations on LinkedIn are put in by the person who is recommending you and directly linked to their profile.
The best way to share this kind of information with a potential employer is through your letter of recommendation and your LinkedIn profile.
