In the Integration management chapter of PMBOK 6, reverse shadowing term is mentioned under manage project knowledge but it is not defined . I searched on google . I found that on URL like knowledgemaverick.com , it is mentioned that when a junior employee trains the senior employees about the new trends or the systems. In wikipedia, it is mentioned as reverse mentoring & its definition almost matches. However, I was informed that reverse shadowing means when junior employee is watched & guided by senior employee while carrying out the tasks which is opposite of work shadowing. Please share your inputs.
