For Marjorie Yang, Dee Poon is a daughter, a co-worker - and one very successful corporate experiment.
Esquel Group Chairman Yang brought in Poon as chief brand officer of clothing label PYE in 2009. Her remit: refresh PYE, which at the time was an ailing part of Hong Kong-based apparel maker Esquel's business.
Esquel specializes in making shirts wholesale for global retail brands including Ralph Lauren and Brooks Brothers, while PYE offers the company's shirt-making expertise direct to retail customers at its own high-end stores.
Poon tells CNBC's Bernard Lo that Yang asked her to join PYE as an "experiment."
"We have a business that isn't making any money and you can't screw up worse than anyone else and you will learn a lot," she recalls of her mother's thoughts at the time.
