The rapid changes in the global economy have imposed high pressure on small and medium-sized enterprises (SMEs) and their operations. Many SMEs have realized how important it is to integrate all units in the business by introducing Enterprise Resource Planning systems (ERP systems).    The adoption decision phase in ERP systems is an early phase and is often confused with implementation, which is a major cause of failure. This confusion can especially hit hard on small and medium-sized companies that may lack sufficient resources. The adoption decision phase can be particularly crucial in such case. The purpose of this study is to investigate which driving forces that influence the adoption decision phase of ERP systems within SMEs. The Technology-Organization-Environment (TOE) theoretical framework was used to create a theoretical foundation for finding drivers from previous research.   Semi-structured interviews were then conducted with six ERP consultants. Respondents' responses were analyzed thematically, and 12 themes were identified as driving forces. These could then be compared with previous research. The driving forces identified were management and decision makers, benefits and efficiency, functionality, regulations and security, competition and the future, industry type and complexity, education and competence, finance and resources, supplier and solutions, integration with existing systems, maintenance and support, and challenges and uncertainty. The driving forces that were identified but could not be linked to previous research were functionality, and challenges and uncertainty.   Keywords: Adoption decision, driving forces, Enterprise Resource Planning systems (ERP system), small and medium-sized enterprises (SME), Technology-Organization-Environment (TOE).

現今的時代，面對全球化的競爭態勢、新興市場崛起、能源危機與金融風暴等因素，台灣的企業在大環境不斷變化之下，掌握市場發展動態，即時回應客戶需求，不斷創新產品與服務，是企業維持競爭優勢不二法門。 ERP隨著軟體技術突破和產業生態蛻變的歷程，其系統面貌也隨之轉換，因此ERP不再只是企業功能的資訊化與經營化，更是科技創新的礎石。許多企業將ERP系統當作企業電子化的基礎，更進一步整合其他的資訊系統，如電子商務(EC)、供應鏈管理(SCM)系統、客戶關係管理(CRM)系統、知識管理系統(KMS)、商業智慧(BI)等。 在現今2010年的後金融海嘯時代，當金融海嘯衝擊以後, 各項國內外經濟評估報告均指出經濟已開始復甦，此刻正是企業重整旗鼓逆勢成長的最佳時刻。對於企業來說，企業資源整合管理的落實不僅是其永續經營的成功關鍵，甚至是其生存的命脈。這也是為什麼在經濟不景氣的環境下，仍有許多企業決心導入ERP系統，以及許多國內外調查報告預測ERP系統的需求與產值仍然會持續成長的主要原因。 本研究的動機之一，即是希望企業在經歷產業變化、策略變動與業務規模的改變之下，如果重新評估ERP系統的適用性，不論是ERP系統需做重新建置或階段性轉換，皆可從不同角度重新探討ERP系統開發與導入過 程的重要策略，而能建置一套對企業真正有效益的ERP系統。 許多企業在發展ERP系統的過程中，都以工程與技術的角度去規劃ERP系統的導入，常會遇到預想不到的結果。對於ERP所涉及的企業流程，利害關係人，導入方法，及對業務流程與關係人的影響，企業導入ERP的策略等，需要做仔細的思考及規劃。 本研究發現在個案公司開發及導入ERP系統的過程中，遇到許多的瓶頸，也面臨了很多問題，導入過程中對企業組織產生了很多影響，改變了原有的作業流程，導入實施後增加許多效益，但某些部份仍需持續改進，ERP系統應確保做到系統整合，需重視細部流程整合方面的分析與資料整合方面的分析。找出ERP系統資料與流程之Gap，並應做到變革管理。 / Nowadays, Facing the globalized competition situation, the emerging markets rise, the energy crisis and the financial storm, Taiwan's enterprises is now under the changing and unceasing environment, the only way to hold on the competitive advantage of Taiwan’s enterprises continuously is to find out the market development tendency, and to response to customer demand immediately, and to innovate product and service unceasingly. The ERP system’s appearance had transformed along with the software technology breakthrough and industrial ecology change. Therefore ERP system is no longer only the enterprise computerize and management tools, ERP is even more the basis of the scientific technology innovation. Many company treat the ERP system as the basis of enterprise’s computerize, furthermore to integrate the ERP system with EC, SCM, CRM, KMS, BI……. In the Late-2010s financial crisis time, after the financial crisis, each domestic and foreign economic appraisal report pointed out that the economy started to recover, It’s the best time to restart and grow up at this moment. The realization of the Enterprise resources integration is not only the key successful factor but also the survival life artery. This is why so many enterprises were still determined to implement the ERP System under the economical depression time, and as well as many domestic and foreign invested report forecast that ERP system's demand and the output value will still continue to grow up. One of this research's motivation, is hopes to re-estimate the important strategy of the ERP implementation from the different point of view, hopes to establish the beneficial ERP system. To review the suitability of the ERP System when the enterprises under the industry change, strategy change and business scale changes, no matter to build a new ERP System or ERP system phase transforming, Many enterprises plan the ERP project by the engineering and technical view, It will always occur the unexpected result. It needs to make the careful considering and plans to all the ERP involves, include the business flows, the stake holders, the implemented methodology, the influence, and the implemented strategy…. This research discovery that while the case company developed and implemented ERP system has meets many bottlenecks, and also has faced many problems. It has had many influences to the enterprise organize while implement the ERP system, It has changed the original business flow, and increases many benefits, But still need to continued improved, The ERP system should assured to realize the system integrated, to pay more attention to the analysis of micro process integration and data integration, find out the gap and do the changing management well.

Customer Relationship Management (CRM) har fått ökad uppmärksamhetunder de senaste decennierna. Sökningar i vetenskapligaartiklar och litteratur visar att det finns behov av kunskap om CRM ochdess funktionalitet. Företaget som studeras i detta arbete är ett friståendeIT‐ och managementföretag som bland annat erbjuder CRMochERP‐system (Enterprise Resource planning) till kunder i olikabranscher. Företaget upplever att kunderna har olika behov och uppfattningarom funktionaliteten inom CRM‐system och även kring CRMfunktionalitetsom kan finnas i andra system såsom ERP‐system. Detfinns funktionalitet inom kundernas ERP‐/ekonomisystem som kanöverlappa funktioner i CRM‐system. Syftet med denna studie är attskapa en ökad förståelse för CRM‐systemens roll och dess funktioner.Resultatet baseras på ett slumpmässigt urval av åtta företag inom olikabranscher som hör till både små och medelstora företag. Undersökningenhar genomförts med hjälp av intervjuer med personer som är insatta iföretagens kundhantering. Information om företagens nuvarande CRMsystem,behov av CRM‐funktioner och egenskaper inom ERP‐/ekonomisystemen som svarar mot de önskade CRM‐funktionernainsamlades. Resultatet visar att företagens behov av nya system kanrealiseras genom utveckling av befintliga system istället för nya system.Det visar också att företagens ERP‐/ekonomisystem enbart används förekonomiärenden och inte för någon CRM‐funktionalitet. Små ochmedelstora företag löser sina CRM‐ärenden med separata IT‐lösningar. / During recent decades, Customer Relationship Management (CRM) hasbeen receiving increased attention. Searches within scientific articles andliteratures show that there is a need for increased knowledge in CRMand its functionality. The company studied in this work is an independentIT and management company that provides CRM and ERP systemsto customers in various industries. According to the companyʹs experience,their customers have different requirements and expectations ofthe functionality within CRM systems and also of the CRM functionalitythat can be found in other systems, such as ERP systems. There isfunctionality within the customersʹ ERP‐/financial systems which mayoverlap functions in the CRM system. The purpose of this study is tocreate a greater understanding of CRM systemsʹ role and its functions.The results are based on a random sample of eight companies in Sweden,within various industries, which are both small and medium sized.The survey was conducted by means of interview sessions with respondentswho are familiar with the company‐customer relationshipmanagement. Interview opportunities concern the collection of informationregarding the CRM functions and features within the ERP‐/financial systems of a current CRM system, which correspond to thedesired CRM functionality. The result shows that the business needs ofnew systems can be realized through the development of existingsystems rather than new systems. It also shows that the companiesʹ ERP‐/financial systems are used purely for financial matters and not for CRMfunctionality. Small and medium‐sized enterprises solve their CRMissues and financial matters by means of separate IT solutions.
