Until a replacement is found, Chang’s responsibilities will be split between the two current general managers in Taiwan: Bannie Tsai and George Shen.
Tsai, who arrived at OMD in April, is in charge of all buying affairs and quality control, and handling key accounts including McDonald’s, Johnson & Johnson, Reckitt Benckiser, Visa, Fedex Express and Watson’s.
Shen, meanwhile, oversees the administrative side of the operation.
Chang is expected to take a break from the industry before assessing his next move.
