Subjective perceptions of value : A qualitative case study using informal evaluation to measure the value of an Information System

Loggert, Josefin, Åhlin, Mairon January 2015 (has links)
The debate on how to measure the value of IT is an ongoing debate within the IT evaluation research. Research about the value of IT tends to focus on formal aspects and ignore informal aspects such as the subjective perceptions of individuals and researchers acknowledge a lack of informal evaluation methods used in practice. This study aims to answer two research questions: How can informal value of IS be evaluated? and What are the benefits and drawbacks of relying on informal value when assessing IS? To answer these questions a qualitative case study have been conducted using the DeLone & McLean IS Success Model as a theoretical framework. The results show that using the model was successful however we argue that important aspects were missing in the model. The benefits of relying on informal value showed to be the possibilities of discovering aspects of value that are not visible in formal evaluation. The drawbacks of performing an informal evaluation are that they are complicated and time-consuming and do not promise useful results.

The role of system administrators in information systems success

Edlund, Sara, Lövquist, Andreas January 2012 (has links)
Limited research has been conducted on how system administrators actually can affect information systems (IS) after they have been implemented; hence, this study examines how system administrators can affect IS success in an implemented IS. The study identified a system administrator´s affect on the three IS quality dimensions in the DeLone and McLean IS success model. The empirical findings was based on a single case study where the data was collected through interviews with the system administrator and the system assistants, but also through a questionnaire answered by the users of the IS. The empirical findings suggested that the system administrator can affect IS success through the IS quality dimensions both directly and indirectly. The system administrator´s affect on IS success proved to be highly dependent on the external system vendor and the structure of the internal support unit.

The information system’s impact on the user’s readiness for change : A study of DeLone and McLean IS success model’s impact on the user’s readiness for change

Leifland, Gustav, Selelyo, Sandor January 2019 (has links)
Information system is a crucial topic in today’s business world. Without a proper information system, it is very difficult to compete on the market. The purpose of the study was to analyze the impact an information system has on the users work and how those factors are assessing the users’ readiness to change to e.g. switch from an existing information system to a new more advanced one. The study was based on the DeLone and McLean IS success model and a single case study was conducted with an inductive research approach. The empirical data has been gathered through semi-structured interviews and the findings show that reliability, response time and IT service of the IS system are the factors with the most influence on the user’s perceived readiness to change. Moreover, the users are not ready to change the current information system that is running within the company for a more advanced one. Position, technical skills and top management are all impacting the user’s readiness to change. Organizationscan use these findings to analyze the users’ satisfaction, their behavior and readiness to face the future changes.

Släpp kontrollbehovet och låt automatiken göra jobbet : En kvalitativ studie om hur ett gränssnitt kan effektivisera publiceringsprocessen

Frithiof, Jessica, Liljeblad, Josefine January 2018 (has links)
Denna studie och uppsats har behandlat samt fokuserat på att synliggöra användarproblem och bearbeta dessa genom bakomliggande teorier kring olika systemegenskaper. Studien utgår från det aktuella administrationsverktyget Everyware. Verktyget Everyware används idag av tidningar och mediehus för att bygga upp och underhålla webbtidningar. En ständig ökning av digital nyhetspublicering bidrar till en konkurrens inom tidnings- och mediebranschen. Detta betyder i sin tur att branschen vill publicera sina nyheter så snabbt och smidigt som möjligt. Detta har varit en bidragande faktor till studiens syfte. Syftet med studien har varit att ta fram ett nytänkande gränssnittsförslag som utifrån användaren ska upplevas som lätthanterligt, smidigt och responsivt. Det teoretiska ramverk som står till grund för studien är baserat på teorin IS Success Model. Med denna teori har studien undersökt vilka framgångsfaktorer ett informationssystem, enligt användarna, bör tillhandahålla. Som komplement till teorin har studien även använt sig av vetenskapliga områden som användarupplevelse, användbarhet och användarnytta. Genom både kedje- och ändamålsenligt urval har åtta potentiella användare av aktuellt verktyg involverats. Det empiriska materialet har samlats in genom individuella semistrukturerade intervjuer samt en gruppintervju. Utifrån det empiriska material som samlades in har sedan tydliga mönster tagits fram för att senare vidareutvecklas och bearbetas vidare i arbetsprocessen. En kategorisering utifrån olika upplevelser kring användandet av det aktuella verktyget, har tagit studien vidare mot gränssnittsarbetet. För att kunna skapa gränssnittsförslag krävdes en analys av det resultat som framkommit. En innehållsanalys och ett affinitetsdiagram skapades för att ta reda på primära önskemål hos användarna gällande administrationsverktygets egenskaper. Utifrån analysen kunde slutligen ett förslag på ett nytänkande gränssnitt för administrationsverktyget Everyware tas fram. Resultatet av denna studie har visat att användare av ett administrationsverktyg, för skapande av webbtidningar, är beroende av att verktyget tillhandahåller särskilda system, information och serviceegenskaper. Dessa egenskaper kan i sin tur leda till förmåner för användare av administrationsverktyget, tidningsbranschen samt läsarna. / This study has addressed and focused on visualizing user problems and processing them through underlying theories about different system properties. The study is based on the current administration tool Everyware. The tool is today used by newspapers and media houses to build and maintain web magazines. An ongoing increase in digital news publishing contributes to competition in the newspaper and media industry. This in turn means that the industry wants to publish news as quickly and smoothly as possible, which has been a contributing factor to the purpose of the study. The purpose of the study has been to develop a new-minded interface proposal which, according to the users, should be experienced as easy to use, smooth and responsively. The theoretical framework for the study is based on the theory IS Success Model. With this theory, the study has investigated what success factors an information system, according to users, should provide. As a complement to the theory, the study has also used scientific areas such as user experience, usability and utility. Through different methods has eight potential users of the current tool been involved. The empirical material has been collected through individual semi structured interviews and a group interview. Based on the collected data, patterns have been developed for further development and adaption in the work process. A categorization based on different experiences regarding the use of the current tool took the study further towards the interface proposal. In order to create interface proposals, an analysis of the result that was obtained was required. A content analysis and an affinity diagram were created to determine primary requirements of users regarding a management tool properties. Based on the analysis, a proposal of a new interface for the Everyware administration tool could finally be made. The result of this study has shown that users of administration tools are dependent on that the tool are providing specific system, information and service characteristics. These characteristics can in turn lead to net benefits for users of the administration tool but also the newspaper industry and the readers.

電子採購影響評估因果模型之建構與驗證 / A causal model of e-procurement impact assessment: theoretical development and empirical application

李洛維, Li, Luo Wei Unknown Date (has links)
目前各國為了提升政府運作效能與國家競爭力,均將電子化政府視為重點發展策略。電子化政府的發展,從早期推動國家資訊基礎建設,到進一步運用資訊通訊科技提供各類政府服務,再到強調行政服務的效率與整合、網路公民參與等,目前已在世界各國形成風潮。電子化政府的普及應用,對於促成公民社會的發展、公義社會的追求及優質網路社會的建構,都帶來相當的影響,也因此當前電子化政府的最新發展為「電子治理」概念的提出。 在電子治理的概念下,電子化政府的評估方式應該從以往的投入-產出之效率評估轉向強調公共目標實現與否的影響評估。然而當前在電子治理影響評估的研究方面仍十分缺乏,雖然目前的電子治理評估研究已經開始重視從使用者的角度進行評估,但評估的焦點還停留在使用者對電子化政府服務的感受,而非電子化政府服務實際對使用者產生何種影響,且尚未以因果模型的方式建構一個完整的電子治理影響評估架構,以找出造成公共目標實現的關鍵因素。 本研究透過國際電子化政府評估研究、電子化政府評估架構、網路服務品質評估研究、電子治理影響評估四類文獻的整理,結合DeLone & McLean的資訊系統成功模型與Heeks的電子化政府價值鏈模型,提出了電子治理影響評估因果模型以及評估指標,同時介紹我國重要的電子化政府服務:「電子採購系統」的發展現況以及相關評估研究,並透過次級資料分析,針對我國電子採購系統進行因果模型的驗證。研究結果證實本研究所提出的電子採購因果評估模型確實具有一定的解釋能力,同時本研究也透過模型實證的結果針對電子採購的政策以及後續研究提出了相關建議。 / eGovernment, as a popular government activity, has adopted by many countries in order to maximize the competitive advantage of nations. As eGovernment activity grows over time, the main issues of e-government change from e-infrastructure to e-service and to e-participation, and this change brings the concern about the impact of eGovernment. Therefore, the latest development of eGovernment is “eGovernance”. Under the concepts of eGovernance, the focus of eGovernment evaluation should change form program evaluation to impact assessment. However, most of literature concerning eGovernance has focused on the supply side, which is the perspective of the government. Little has focused on the evaluation of actual use and its impact in e-government service. This research reviews literatures and related reports, based on Heeks’ eGovernment Value Chain Model and DeLone and McLean’s Information System Success Model, proposes a causal model for the empirical examination of impacts of the e-Procurement System in Taiwan, this model is strongly supported by the empirical data. This research also makes some suggestions for the improvement of e-Procurement policy in Taiwan, and for futher researches.
