對於臺灣，服務業佔生產毛額GDP比重已經達到七成的狀況下，由於製造業設備自動化的技術不斷提升，服務業必然持續承受就業結構調整後新增的人力資源，服務業的創新在近幾年由於科技發展所賜，出現如人力銀行、線上遊戲、網路購物...等以往不曾出現的商業模式，而被認定服務業標準代表的餐旅產業也藉著這股創新風潮，開拓更多不同的經營模式，在連鎖式餐飲業發展初期追求是單一品牌的規模極大化，隨著國際市場的開放逐漸達成全球化目標，卻發現單一品牌會逐漸受到市場需求極大化的影響而讓營收成長幅度受限，餐飲經營者開始思考改變現況的方法，因此利用併購或自行創新成為多品牌餐飲集團就逐步成為風潮。
多品牌的餐飲經營使得管理模型變得更加複雜化，以往只需要控制的少量變數突然增多出來，例如進料種類的多樣性、烹調設備的複雜化、服務人員的標準流程差異...都使得單純的經營策略不再具有一貫性的暢通優勢，以麥當勞為例，以往用迪士尼贈品來吸引年齡層較低的顧客拖引父母來消費的模式，在轉投資的墨西哥大王玉米餅Chipotle Mexican Grill是完全無效的策略，因為客層年齡的區別，這兩間同集團的餐飲品牌便要創新出各自適用的內部生產與外部服務模組，對於集團而言能將不同年齡層的客源都成為營收的貢獻者，是提昇總體營收幅度的最佳辦法，但對於管理者而言必須面對不同的經營模式分別作出差異的創新策略，卻是更加困難的挑戰。
多品牌餐飲在臺灣已經是被廣為接受的經營模式，餐廳的高階經營者必須面對不同消費價位與偏好的族群，必須訂定不同的操作方式以滿足不同階層客戶的滿足感知，為達成此目標，新興的服務科學可以成為有效的工具，其中的服務創新可以提供各種不同價位與型態的餐廳永續經營的生存力量，來避免破壞者的傷害。在此篇論文中，我們將以台北的新上享餐飲集團作為研究的個案，利用內部與外部的服務創新因子分析來歸納其調整與改善的途徑，並且作為營運中心與各分店服務創新的參考。

In Taiwan,the service Indutry almost has covered 70% in GDP,the manufacturing will increase more auto-condition equipment to substitute as labors.More human resource enter the service industry and creat new business model by iternet technology,like job bank, on-line game,virtual store…and the hospitality field also take this trend to development new business more.Before,in business economy,the C.E.O. will expand their enterprise as big as the world in one company brand.But they find one brand will lose some market share and is really hard to cover higher market ratio.Multi-Brand business model is useful for market expanding strategy,even hospitality owners chang the direct to vreat or merge more restaurant brand in their group.
Multi-Brand business in hospitality is a new challenge for most executor,they have to control more varience in different material,equipment,receiption….,factor is not so simple as one brand business, the executor must change or modify the policys for each brand.As Mcdonald usually offer some free gift for the kids,then more children client will be attracted by this operation, but it is not useful in Chipotle Mexican Grill.Each brand in the same group have to set the effective marketing criterion for independent brand from same person in central administration system.It is difficult for managers to make the decesion to help the different layer of price store.
Multi-Brand hospitality is accepted by most of Taiwan hospitality group now, in this case, the executors will need more kinds of operation to increase every brand customers` satisfaction perception.Due to this target, service science is a good tool to modify any kind of restaurant performance, in sevice science, the service innovation bring forever power to avoid the strong competitors` elimination.In this thesis, newenjoy restaurant goup will be cast study example,we use inside and outside innovation factor to compare a better service innovation path and conduct modify analysis for headquator and branch stores.
