PUreGMS is a product environmental quality assurance system implemented by Pegatron Corporation; it is a part of the quality system of the whole company to diminish or eliminate hazardous substances listed in RoHS, WEEE and other applicable standards or legislation regulated by each country. Pegatron Corporation implements”Hazardous Substances Free (HSF) Assurance Program” for its products, and thus, every employee must understand HSF related requirements before implementing HSF tasks in daily operations. In order to let every employee understand HSF requirements, new employees are required to complete a basic course and pass a quiz via our e-learning system within one month after joining the company. An Intermediate course and quiz must be completed and passed within three months after joining, and for every one who has been assigned HSF related tasks. This is to ensure that employees who are responsible for part approval tasks fully understand how to complete the survey form and check details and further understand the concept and function of the e-Green platform, so that they can complete parts approval tasks appropriately. The participants have to complete and pass the intermediate and advanced course and quiz within three months after joining, or if they are newly- assigned for part approval tasks.
