a real world point of view
Prior to her work on Doctor Who, she had been the 3rd AD throughout the first, 2006 series of the Nickelodeon sitcom, Genie in the House. She moved to Doctor Who during its third series, where she took a nominal demotion to become a runner. Over the course of David Tennant's final two series, she was credited as all three kinds of runner used by BBC Wales: simple runner, production runner and floor runner. By The Next Doctor, she had been promoted to 3rd assistant director, but was not credited in any of the other 2009 Specials. During 2009 she was instead the 3rd AD on Lark Rise to Candleford with Sarah Lancashire and Julia Sawalha. She then returned to the position of 3rd AD at the beginning of Matt Smith's first series.
Her name is a cause for some confusion as it has been variously hyphenated throughout her career. The most correct version is apparently the one given in her chyron on Confidential: Heddi-Joy Taylor-Welch. However, Doctor Who never offered her any sort of hyphenation, either before or after her marriage, until Victory of the Daleks. She has, however, been consistently styled as "Heddi-Joy" on other productions.
