Supply management is cross-functional,meaning it involves purchasing, engineering, supplier quality assurance, thesupplier, and other related functions working together as one team, early on,to further mutual goals.

請教各位老師：to further mutual goals目的狀語，early on時間狀語，那樣working together as one team在句中干什么成分？是做involves的賓語補語嗎？

我的理解：other related functions working together as one team, early on, to further mutual goals. 整體是involves 的賓語，和and前面的幾個賓語并列。working together as one team，early on, to further mutual goals 整體又是other related functions的后置定語，等于定語從句有哪些用途。
