長久以來，企業核心競爭能力早已被公認是企業獲利以及維繫的驅動者，對於服務業當然也不例外。為了有效生存於現今惡劣的商業環境，服務業必須維護其服務能力之成熟度，以使用者為服務的核心，並以消費者的需求為服務的出發點。唯有以客戶為本，才能使企業永續經營，故台灣服務業若要加入國際市場營運，企業服務能力將扮演一個相當重要的角色。 隨著人類壽命的延長、以及關心個人健康的中產階級崛起，健康檢查已逐漸成為新全民運動。由於市場龐大與需求旺盛，為了服務有健康意識且經濟條件佳的客群，全台醫院和專業診所紛紛設立健康管理中心，提供燈光美、氣氛佳、餐點好、服務親切的健檢環境，其中不少醫院更是砸下重金，重新改造內部裝潢與購買最新式的檢查儀器。因此，高階健檢產業如雨後春筍般的蓬勃成長。 本研究認為，為了實現更高的服務品質，高階健康檢查事業應適當的進行商業流程再造。藉由不斷地改善流程，企業得以回應並滿足顧客的需求，增加企業服務顧客的能力，持續提升服務品質。因此，本研究引用服務企業流程模式的架構，以高階健康檢查事業為研究對象，主要的研究問題分為三大部分：一為適用高階健康檢查事業的服務能力評量模式發展，其二為編輯符合實務用詞的流程領域描述說明，其三為提供高階健康檢查事業品質成長的參考軌跡。 本研究之結果，定義了高階健康檢查事業服務能力等級與成熟等級之表述方式，主動性的給予被評鑑機構一個品質提升的建議與參考的軌跡。本研究設計一套『高階健康檢查事業服務能力成熟度之自我評鑑與改善建議系統』，協助高階健康檢查事業自我評量服務成熟等級，並提供透過資訊科技應用來提升等級的建議。透過階段性的資訊科技應用採納，可妥善配置資訊科技採納進程並編製預算執行順序，來強化醫療照護服務的能力成熟度等級。 / Core competitiveness of enterprise has long been recognized as the driver of profits and sustainability of a business. Service industry is certainly in no exception. In order to effectively survive in today's harsh business environment, services business must maintain its maturity of service capabilities, treat consumer as the core of the services and serve the consumer need as the basic of services. Such consumer-oriented strategy is the key to ensure the long term prosperity of business. It is also essential to Taiwan's service industry for her successful operations in international market. With the extended human lifespan, as well as the rise of the middle class with concern about personal health, health checkup service has become a new national sport. In order to serve customers, who have health-conscious mind and favorable financial affordability, hospitals in Taiwan provide specialized clinics and health management centers. They offer soothing lights and good atmosphere as well as healthy meals and friendly services. Such reformation in health checkup business has seen vigorous market growth and received significant investment on both medical equipment and interior remodeling of examination facility. This study suggests that in order to achieve a higher quality of advanced health checkup service, adequate business process reengineering should be carried out as per need. With constantly improving processes, the service unit would be able to respond and fulfill the customer needs, increase the customer service capacity of the enterprise, and continue to improve service quality. Therefore, this study adapts service business process model as research framework and chooses advanced health checkup business as the research subject. The main research questions are divided into three parts: first is developing a service capability evaluation model for advanced health checkup business; second is editing descriptions of process areas in line with practical terms; third is providing a roadmap of advanced health checkup business to improve their service quality. Results of this study helps to define the capability level representations and maturity level representations for advanced health checkup business. It could proactively provide suggestions to and also be adopted as a reference roadmap for service quality improvement by the evaluated companies. This study also implements a “self-evaluation and improvement recommendation system for advanced health checkup service capability maturity level”, which assists advanced health checkup business to self-assess the maturity level of service capability, and provide recommendations to enhance the level through IT applications. Through the stage-wise IT application adoption, it could properly arrange IT adoption schedule, prepare budget execution order and strengthen the maturity level of health care services capability.

Abstract Software process assessment and improvement came under the spotlight in the discussion of software engineering when the Software Engineering Institute published the maturity model for software process capability determination in 1987. Since then, several new approaches and standards have been developed. This thesis introduces a European software process assessment and improvement methodology called BOOTSTRAP, which was initially developed in an ESPRIT project starting from lean and kaizen philosophy. The focus is on the evolution of methodology and how it was developed, using an experimental research approach. The work covers also enhancements to the methodology investigated in the SPICE, PROFES and TAPISTRY projects. The enhancements expand the original methodology into new specific application areas, keep it compliant with new quality standards and certification, improve the efficiency of the assessment method, enhance the focus from process to product and strengthen improvement monitoring and support. To address these areas, the new BOOTSTRAP methodology releases offer tailored and enhanced assessment reference models and enhanced assessment and improvement methods. The new features also facilitate more frequent and even continuous assessments with software measurement-based indicators. The thesis explains the origin and features of BOOTSTRAP software process assessment and improvement methodology and how it was developed for professional use. The discussion starts with the evolution of the methodology. Then the new trends and demands are introduced and new features of the BOOTSTRAP methodology described. The conclusion discusses how the methodology developed to be able successfully to support professional software process assessment, to align it with the evolution of software engineering, to adopt the features and requirements of the underlying standards in order to conform to the requirements set by ISO 15504 standard and to become validated in practice. / Tiivistelmä Ohjelmistoprosessin arvioinnista ja parantamisesta tuli ohjelmistotekniikan keskeinen kiinnostuksen kohde kun Carnegie-Mellon yliopiston ohjelmistotekniikan instituutti SEI julkaisi kypsyysmallinsa ohjelmistoprosessin kyvykkyyden arviointiin vuonna 1987. Siitä lähtien maailmalla on syntynyt lukuisa määrä uusia malleja ja standardeja tälle alueelle. Tässä väitöskirjassa esitellään eurooppalainen ohjelmistoprosessin arviointi- ja parantamismenetelmä BOOTSTRAP, joka kehitettiin alun perin Euroopan unionin ESPRIT tutkimusohjelman rahoittamassa projektissa lähtien japanilaisesta ohut-ajattelusta (Lean) ja sen jatkuvan parantamisen periaatteesta (Kaizen). Esitys keskittyy menetelmän kehittymiseen ja siihen miten menetelmä käytännössä kehitettiin käyttäen kokeellista tutkimustapaa teollisessa ympäristössä. Työ kattaa myös alkuperäiseen menetelmään tehdyt laajennukset, jotka syntyivät yhteistyössä SPICE, PROFES ja TAPISTRY projekteissa tehdyn tutkimuksen tuloksena. Tehdyt laajennukset mahdollistavat menetelmän käytön uusilla sovellusalueilla, takaavat menetelmän yhteensopivuuden alan laatu- ja sertifiointistandardien kanssa, parantavat menetelmän tehokkuutta, laajentavat menetelmän käyttöaluetta prosessin arvioinnista sisältämään myös tuotteen kehittämisen arvioinnin ja vahvistavat parantamisen seurantaa ja tukemista. Toteuttaakseen näiden uusien ominaisuuksien vaatimukset uudet BOOTSTRAP menetelmän julkistukset tarjoavat räätälöityjä ja laajennettuja mallikuvauksia arviointien tekemiseksi sekä entistä täydellisempiä lähestymistapoja arviointien suorittamiselle ja parantamiselle. Menetelmän uudet ominaisuudet mahdollistavat myös usein toistuvien arviointien suorittamisen ja jopa jatkuvan arvioinnin ohjelmisto-mittauksia hyödyntäen. Väitöskirjassa kuvataan yksityiskohtaisesti BOOTSTRAP menetelmän lähtö-kohdat ja ominaisuudet ja se kuinka menetelmä onnistuttiin kehittämään ammattimaiseen ohjelmistoprosessin arviointiin ja parantamiseen sopivaksi. Ensin kuvataan menetelmän kehittyminen ja sitten edetään alan uusien kehitystrendien ja vaatimusten esittelyyn siihen kuinka BOOTSTRAP menetelmä uudet ominaisuudet vastaavat näihin vaatimuksiin. Yhteenvedossa osoitetaan kuinka kehittämisessä onnistuttiin saamaan aikaan uusi menetelmä, joka sopii ammattimaiseen ohjelmistoprosessin arviointiin, vastaa kaikilta osin alan kehittymisen vaatimuksia, sisältää alan standardien vaatimukset täyttävät käytännössä koestetut ominaisuudet, jotka takaavat menetelmän vastaavuuden ISO 15504 standardin vaatimuksiin.
