過去顧客對產品與服務品質的滿意與否,總被認為是成正比關係的線性思維。然而,研究證實有一些服務品質與顧客的滿意是非線性的,有些服務項目只能增加一點點顧客滿意度,而有些服務項目雖只是在效能上稍做改進,卻能大幅度地提昇顧客滿意度。有別於傳統評量產品或服務品質的模式。本研究的目的在於辨識餐飲服務中具有績效或不具績效的服務項目並提出改善方向。 本研究從新設計原本用於評量銀行服務品質的SQ-Need 量表,取其具有「知識」與「審美」的特徵構面。引用狩野紀昭(Kano Noriaki)的二維品質要素歸類,用以區分各種服務品質的要素歸類。再由Matzler & Hinterhuber的品質改善指標積分,估算其可能增加的滿意度和減少的不滿意度的積分排序。 從某法式餐廳的研究結果發現由300位消費者對28項品質屬性的知覺資料,歸類出三種服務項目的績效:魅力品質等9項、線性品質等8項及無差異品質等11 項。利用品質改善指標積分排序取前十項,可以從增加滿意度指標提昇會增進顧客滿意的服務項目,由減少不滿意度指標則可即刻消彌顧客不滿意的服務項目。意圖從研究結論的管理意涵發展出一套提昇餐飲服務品質的策略,提供餐飲業者在實務上作為改善餐廳產品與服務品質的建議。
