本課程針對企業採購責任者設計，亦適合供應端銷售相對的責任者，聚焦於兩者互動如何運作。因採購面對供應端的業務，專業採購工程師面對供應端的技術族群，自然產生許多互動中的難題，因此有必要由此專業領域的高人，來指點工作疑惑/盲區和困難，藉此提升雙方責任者工作成效，於互利中如何各取所需，此為本課的設計方向和目的。

因此課程設計七大方向，先談「商務交易核心價值」，從買賣雙方互利交易角度開始，再談「影響買賣的各種商務變數分析」及「價值及價格和成本分析」，雙方有必要認識交易互動的量化基礎為何，四談「雙方合約」內容，目的希能提醒和解決所有商務合約的問題，五談「商務談判的執行技巧」，從議價/選定/跟催/售服之四大方向，解說執行面運用技巧，並搭配分組案例演練，目的希望學員能活用相關技巧；六談「雙方經常面臨例行工作層面的互動問題」，如供商調查評估/料件承認及管制/料件驗收/評比因應/供商策略/關係拿捏等，目的解讀如何提升工作成效；最後談「國際專業採購(IPO)的運作」，其內容具兩大意義，其一使中大型供應端業務責任者，知悉如何和國際買方大咖互動，其二如何取得訂單/如何滿足客戶要求等。
本課講師曾任職買方 IBMT-IPO十餘年，長期因應「採購與供應之商務互動」，亦曾服務製造供應方等，故其為本課講師最為適當者，學員將受益無窮。

本數位課程，聚焦於第5章到第7章，稱「下部」。
