The diploma thesis is focused on successful and unsuccessful IT projects with critical success factors detail. The purpose of the diploma thesis is obtaining a list of critical success factors in the theoretical part. The list could be interesting for success in IT projects. The list of critical success factors will be subject of examination in the practical part. Firstly I will compile a questionnaire which will contain all critical success factors from the theory. In the next step, I will meet with IT project managers who have got a lots of experiences in the branch. After that I will have completed questionnaires by IT project managers and I will evaluate critical success factors. These critical success factors will be compare with the theory. Finally I will create table with the most important critical success factors according to IT project managers.

The purposes of this dissertation were to define enterprise resource planning (ERP) systems, assess the varying performance benefits flowing from different ERP system implementation statuses, and investigate the impact of critical success factors (CSFs) on the ERP system deployment process. A conceptual model was developed and a survey instrument constructed to gather data for testing the hypothesized model relationships. Data were collected through a cross-sectional field study of Indian production firms considered pioneers in understanding and implementing ERP systems. The sample data were drawn from a target population of 900 firms belonging to the Confederation of Indian Industry (CII). The production firms in the CII member directory represent a well-balanced mix of firms of different sizes, production processes, and industries. The conceptual model was tested using factor analysis, multiple linear regression analysis and univariate Anova. The results indicate that the contributions of different ERP system modules vary with different measures of changes in performance and that a holistic ERP system contributes to performance changes. The results further indicate that the contributions of CSFs vary with different measures of changes in performance and that CSFs and the holistic ERP system influences the success achieved from deployments. Also, firms that emphasize CSFs throughout the ERP implementation process achieve greater performance benefits as compared to those that focus on CSFs during the initial ERP system deployment. Overall, the results of the study support the relationships hypothesized in the conceptual model.

Purpose: This research reviews the Project Implementation Profile (PIP) and explores its relevance to Upgrading Informal Settlements Programme (UISP) type projects in Cape Town. The research aims to: • Identify the most common PIP Critical Success Factors (CSF) for UISP projects, • Compare the common PIP Critical Success Factors (CSF) for UISP projects to the Construction Sector CSF • Evaluate if the PIP tool is applicable to UISP projects. • Determine if there any other critical success factors that need to be added to the CSF list that is critical to the UISP Project success Approach: A literature review was conducted to assist in identifying the common CSF in the Constructions Sector. A survey questionnaire was sent out to relevant UISP Project Managers. The survey questionnaire was based on the PIP questionnaire with additional questions regarding to the effectiveness of the PIP tool on UISP projects. The intent of the survey questionnaire is firstly to establish the common CSF for UISP projects and then evaluate the PIP effectiveness on UISP projects. Findings: Based on the research results, it was found that the high scoring CSF for UISP projects were Project Mission, Client Consultation, Technical Tasks, Monitoring and Feedback, Personal. When the high scoring CSF was compared to the Literature Based Construction Sector CSF, the following common CSF was established: Monitoring and Feedback, Client Consultation and Technical Tasks. Practical Implications: This research will give an indication of the high and low scoring CSF relevant to UISP projects, which project managers and Managers in the Human Settlements industry can use to evaluate their UISP or Breaking New Ground (BNG) housing projects. Furthermore, the PIP tool may be utilised more frequently as a project quality success assurance tool in the organisation. The PIP tool has been tested and verified in a number of different industries in previous studies but never in its application to UISP or BNG projects.

Today's organizations are characterized by digitization, development and growth. A wellimplemented ERP-system that match the processes of an organization can lead to a number of benefits. ERP-implementations and critical success factors are a well-researched area. Nevertheless, a great number of ERP-implementations are still considered as failures, which makes further research around the area considered relevant. This study aims to investigate what is critically related to important success factors in implementing ERP-systems. The study began with a literature study in which 15 scientific articles were reviewed, of which 69 success factors were identified. Of those, the six most common were selected as the basis for this study. In order to answer the purpose of this study, interviews were conducted with project managers who had a lot of experience from ERP-implementations. Using the results from these, as well as the collected theory, comparisons have been made between them. This, in turn, has resulted in a finding that communication is a key part of the entire ERP implementation and in all the critical success factors investigated in this study. Hence, the interaction between supplier and customer is seen as critical in ERP implementations, so they understand each other, have shared expectations and a realistic commitment to ERP implementation.

Syftet med denna kandidatuppsats i informatik är att ge fallföretaget underlag att använda föratt kunna förbereda sina medarbetare inför ett systembyte och därmed undvika vanligafallgropar. Uddeholm AB är studiens fallföretag och syftet har formulerats utifrån ettkunskapsbehov företaget upplever. Litteraturstudier har använts för att precisera studiensfrågeställningar och som underlag för en intervjuguide som användes i intervjuer medanvändare och systemexperter.Undersökningsfrågorna handlar om vilka åtgärder som behöver vidtas för att förberedaanvändare inför det kommande affärssystemsbytet, samt hur dessa åtgärder ska utföras. Dessafrågor har besvarats från både ett användarperspektiv och perspektiv från systemexperter.Slutsatserna ur ett användarperspektiv var att användarinvolvering var viktigast. Detta menaranvändarna kan göras genom att de får vara delaktiga i att identifiera brister i det nuvarandesystemet och därmed bidra med hur de anser att det kommande systemet ska anpassas. Andraslutsatser var att key users kunde användas till att motivera medarbetarna, att få tid tillutbildning innehållande introduktion, testning i verklig miljö, ta del av nya funktioner menäven att jämföra nya affärsprocesser med nuvarande som användarna inte ville skulle ändras.Manualer ansåg användarna vara oväsentliga medan däremot lathundar, chattfunktioner ochhjälpbubblor hade varit bättre. Aktiva ledningsstöd ansåg användarna vara viktigt och det kangöras genom att de delar med sig av lättillgänglig information, har en kontaktperson blandanvändarna och att användarna får delta i möten och avstämningar.Systemexperterna anser att användarinvolvering är oerhört viktigt och menar att workshopskan användas för detta men berättar inte i vilket syfte. Utbildning i det nya systemet ärmycket väsentligt anser de också. Deras uppfattningar om utbildningens innehållöverensstämmer med användarnas med avseende på introduktion och ta del av nya funktioner.De nämner interaktiva filmer som en del av användarutbildningen vilket inte användarnanämner men deras förslag med testning i verklig miljö kan vara jämförbart. Systemexperternaanser att det kan vara en nödvändighet att användarna ändrar sina arbetsprocesser. Dettaskiljer sig ifrån användarnas önskemål. Systemexperterna anser också att ledningens aktivastöd inte är viktigt vilket också skiljer sig från användarnas uppfattning som menar attledningens stöd är väsentlig.

Syftet med denna uppsats var att utveckla kunskap kring vilka faktorer som påverkar implementeringen och upprätthållandet av Lean i tandvård. För att belysa detta syfte användes en kvalitativ ansats där det genomfördes fem intervjuer med nyckelpersoner i två fall, som sedan kompletterades med tre intervjuer av respondenter som inte var kopplade till något av fallen. I tillägg till dessa intervjuer gjordes en dokumentstudie relaterad till fallen där sju dokument analyserades. Intervjuerna transkriberades och en innehållsanalys gjordes genom kodning. Resultatet av studien genererade ett antal framgångsfaktorer och korresponderande hinder för implementeringen och upprätthållandet av Lean. De kritiska framgångsfaktorerna som identifierades var ledarskap som har intresse för Lean, ledarskap som driver Lean-konceptet kontinuerligt, informationsdelning och utbildning och anpassning av Lean till den egna organisationen. Det största hindret var motstånd från personalen, ett hinder som användandet av informationsdelning hjälpte att reducera. / The purpose of this thesis was to develop knowledge about which factors affect the implementation and maintenance of Lean in dental care. To study this, a qualitative method was used where five interviews were conducted with key persons in two cases, which were then supplemented with three interviews with persons that were not connected to the two cases. In addition to this, a document study was made related to the cases where seven documents were analyzed. The interviews were transcribed, and a content analysis was done through coding. The results generated several critical success factors and corresponding barriers to the implementation and maintenance of Lean. The critical success factors that were identified were leadership that has an interest in Lean, leadership that drives the Lean concept continuously, information sharing and education of employees and adaptation of Lean to the individual organization. The biggest barrier was resistance from staff, however, the use of information sharing helped to reduce it.
