Basically, are you into Quality Assurance or Productivity & Quality Department its not clear.Besides, i can give little bit light on quality assurance . If you are into Quality Assurance means you have to take training into IMS (Intergrated Management Systems) which related to your organisation product and services. The trainings are ISO 9001:2008 (QMS), ISO 14001:2004 (EMS) and ISO 18001:2007 (OSHAS) and with additional of Six sigma BlackBelt. Cheers.
