The objective of the thesis is to structure and model the factors that contribute to and can be used in evaluating project success. The purpose of this thesis is to enhance the understanding of three research topics. The goal setting process, success evaluation and decision-making process are studied in the context of a project, business unitand its business environment. To achieve the objective three research questionsare posed. These are 1) how to set measurable project goals, 2) how to evaluateproject success and 3) how to affect project success with managerial decisions.The main theoretical contribution comes from deriving a synthesis of these research topics which have mostly been discussed apart from each other in prior research. The research strategy of the study has features from at least the constructive, nomothetical, and decision-oriented research approaches. This strategy guides the theoretical and empirical part of the study. Relevant concepts and a framework are composed on the basis of the prior research contributions within the problem area. A literature review is used to derive constructs of factors withinthe framework. They are related to project goal setting, success evaluation, and decision making. On the basis of this, the case study method is applied to complement the framework. The empirical data includes one product development program, three construction projects, as well as one organization development, hardware/software, and marketing project in their contexts. In two of the case studiesthe analytic hierarchy process is used to formulate a hierarchical model that returns a numerical evaluation of the degree of project success. It has its origin in the solution idea which in turn has its foundation in the notion of projectsuccess. The achieved results are condensed in the form of a process model thatintegrates project goal setting, success evaluation and decision making. The process of project goal setting is analysed as a part of an open system that includes a project, the business unit and its competitive environment. Four main constructs of factors are suggested. First, the project characteristics and requirements are clarified. The second and the third construct comprise the components of client/market segment attractiveness and sources of competitive advantage. Together they determine the competitive position of a business unit. Fourth, the relevant goals and the situation of a business unit are clarified to stress their contribution to the project goals. Empirical evidence is gained on the exploitation of increased knowledge and on the reaction to changes in the business environment during a project to ensure project success. The relevance of a successful project to a company or a business unit tends to increase the higher the reference level of project goals is set. However, normal performance or sometimes performance below this normal level is intentionally accepted. Success measures make project success quantifiable. There are result-oriented, process-oriented and resource-oriented success measures. The study also links result measurements to enablers that portray the key processes. The success measures can be classified into success domains determining the areas on which success is assessed. Empiricalevidence is gained on six success domains: strategy, project implementation, product, stakeholder relationships, learning situation and company functions. However, some project goals, like safety, can be assessed using success measures that belong to two success domains. For example a safety index is used for assessing occupational safety during a project, which is related to project implementation. Product safety requirements, in turn, are connected to the product characteristics and thus to the product-related success domain. Strategic success measures can be used to weave the project phases together. Empirical evidence on their static nature is gained. In order-oriented projects the project phases are oftencontractually divided into different suppliers or contractors. A project from the supplier's perspective can represent only a part of the ¿whole project¿ viewed from the client's perspective. Therefore static success measures are mostly used within the contractually agreed project scope and duration. Proof is also acquired on the dynamic use of operational success measures. They help to focus on the key issues during each project phase. Furthermore, it is shown that the original success domains and success measures, their weights and target values can change dynamically. New success measures can replace the old ones to correspond better with the emphasis of the particular project phase. This adjustment concentrates on the key decision milestones. As a conclusion, the study suggests a combination of static and dynamic success measures. Their linkage to an incentive system can make the project management proactive, enable fast feedback and enhancethe motivation of the personnel. It is argued that the sequence of effective decisions is closely linked to the dynamic control of project success. According to the used definition, effective decisions aim at adequate decision quality and decision implementation. The findings support that project managers construct and use a chain of key decision milestones to evaluate and affect success during aproject. These milestones can be seen as a part of the business processes. Different managers prioritise the key decision milestones to a varying degree. Divergent managerial perspectives, power, responsibilities and involvement during a project offer some explanation for this. Finally, the study introduces the use ofHard Gate and Soft Gate decision milestones. The managers may use the former milestones to provide decision support on result measurements and ad hoc critical conditions. In the latter milestones they may make intermediate success evaluation also on the basis of other types of success measures, like process and resource measures.

The implementation of Metalib in UOC's Library was framed within a project centred on the end user. For the adaptation of Metalib to the users' needs and search behaviour, we carried out three tests: - One with students, conducted by a consulting company; - A second one with teachers, carried out by the Library; - The third, with teachers and staff, also was carried out by the Library, after having made some changes resulting from the first and second tests. The tests, made with the software Morae, underlined a number of difficulties to understand the concepts related to metasearching. The tests also showed difficulties in navigating and in managing search results. All the information gathered was used to improve navigation through the interface. The presentation tells about the tests' methodology, the conclusions reached through this experience, and the decisions finally taken by the Library to improve the Metalib interface.

This paper presents a reflection on the need for libraries to think about how to facilitate access to the documentary sources they manage.As the number of resources available in electronic form increases, libraries are in the need to provide a simple and usable search tool that allows integrating the contents of the various information management systems they give access to.To define user expectations to the search interface, some of the features that they are accustomed to use in their requests for information on the Internet have been included.The technologies that allow the discovery layer implementation as a search tool that integrates the various information systems of the library are presented next. And below are some examples of implementations that work in line with the integration of various information sources into a single search engine, as models to consider for implementing a system of this kind.The purpose of it all is to present a state of the art of some cases of operational deployments as a starting point for any organization interested in improving access it offers to its resources on the basis of references study.

This work presents new, efficient Markov chain Monte Carlo (MCMC) simulation methods for statistical analysis in various modelling applications. When using MCMC methods, the model is simulated repeatedly to explore the probability distribution describing the uncertainties in model parameters and predictions. In adaptive MCMC methods based on the Metropolis-Hastings algorithm, the proposal distribution needed by the algorithm learns from the target distribution as the simulation proceeds. Adaptive MCMC methods have been subject of intensive research lately, as they open a way for essentially easier use of the methodology. The lack of user-friendly computer programs has been a main obstacle for wider acceptance of the methods. This work provides two new adaptive MCMC methods: DRAM and AARJ. The DRAM method has been built especially to work in high dimensional and non-linear problems. The AARJ method is an extension to DRAM for model selection problems, where the mathematical formulation of the model is uncertain and we want simultaneously to fit several different models to the same observations. The methods were developed while keeping in mind the needs of modelling applications typical in environmental sciences. The development work has been pursued while working with several application projects. The applications presented in this work are: a winter time oxygen concentration model for Lake Tuusulanjärvi and adaptive control of the aerator; a nutrition model for Lake Pyhäjärvi and lake management planning; validation of the algorithms of the GOMOS ozone remote sensing instrument on board the Envisat satellite of European Space Agency and the study of the effects of aerosol model selection on the GOMOS algorithm.

This article reflects the analysis of personal and social competences through the study and analysis of creative tensión in engineering students, using a computer application called Cycloid. The main objective was to compare the students' creative tensión by asigning them the task of being the project leader of a given project: their own university major. The process consisted of evaluating, through special surveys, a group of students to know the current situation of competences, using fuzzy logic analysis. From this self-knowledge, provided by the survey, students can know their strong and weak characteristics regarding their study habits. Results showed that tolerance to stress and to language courses are the weaker points. This application is useful for the design of study strategies that students themselves can do to better face their courses

The purpose of the Master’s Thesis is to study the best practices to virtual project management from the project manager’ point of view. The best practices are divided according to a five-phase virtual project life cycle model. Each phase include concrete suggestions for actions. Research’s theoretical background is wide because of the broad subject matter. In the theoretical part topics such as virtual working, virtual project management challenges are examined and some concrete actions to tackle these challenges are introduced. Thesis’ approach is constructive, where a known problem is solved piece by piece after creating a pre-understanding of the topic. Existing research work is utilized when creating a model for virtual project team management. The basis of the model comes from various best practices read from literature and from the interviews conducted on experienced virtual project managers in the case organization. As a result the model combines both previous research and the organizations empirical experience. As an output of the thesis a model for virtual project team management is developed, which can be used as a guideline by the virtual project managers in their work. The model includes actions and practices what can be used to overcome the challenges of virtual project management.

The application of information technology (IT) in customer relationship management (CRM) is growing rapidly as many companies implement CRM systems to support their numerous customer facing activities. However, failure rates of CRM projects remain notably high as they deliver scant solutions and poor user acceptance. As a consequence, it is justified to study previously researched CRM success factors and apply them to CRM system implementation. The aim of this master’s thesis was to get acquainted with relevant academic theories, frameworks and practices concerning CRM and agile development, and use them to generate a modified CRM project strategy to support the successful execution of the case company’s, Process Vision Oy, CRM implementation project. The empirical CRM system implementation project was conducted simultaneously with writing this thesis. Its theoretical findings could be transferred into practice through active participation in the CRM system development and deployment work. The project’s main goal was to produce and take into use a functioning CRM system. The goal was met, since at the time of printing this thesis the first system release was successfully published to its users at Process Vision’s marketing and sales departments. The key success elements in the CRM project were cyclic, iterative system development, customer oriented approach, user inclusion and flexible project management. Implying agile development practices ensured being able to quickly respond to changes arising during the progress of the CRM project. Throughout modelling of the core sales process formed a strong basis, on which the CRM system’s operational and analytical functionalities were built. End users were included in the initial specification of system requirements and they provided feedback on the system’s usage. To conclude, the chosen theoretical CRM roadmaps and agile development practices proved as beneficial in the successful planning and execution of the agile CRM system implementation project at Process Vision.

Tässä diplomityössä käydään läpi lähestymistapoja sovellusintegraatioon ja niiden käyttöä yritysmaailmassa. Sovellusintegraatiolla tarkoitetaan prosessia jolla yhdistetään toimintoja tai tietoa kahdesta tai useammasta sovelluksesta ja luodaan yhtenäinen kokonaisuus toiminnallisuuksia tai tietoa. Sovellusintegraation toteuttamiseksi on olemassa erilaisia lähestymistapoja ja menetelmiä. Näillä prosesseilla pyritään linkittämään kaksi tai useampia sovelluksia toisiinsa. Sovellusintegraation avulla saadaan jo olemassa olevista järjestelmistä tietoa, pystytään hyödyntämään elektronista kaupankäyntiä, saadaan integroituja toimitusketjuja, ja saadaan jaettua tarpeelliset prosessit. Sovellusintegraatio on strateginen lähestymistapa monen tietojärjestelmän yhteensitomiseksi. Tietojen vaihto ja reaaliaikainen toiminta on tärkeää. Sovellusintegraation tuloksena käytettävissä oleva informaatio ja prosessit sisäisten- ja ulkoisten systeemien välillä tuottavat selkeää strategista etua. Työssä toteutettiin kohdeyritykselle järjestelmä jonka avulla voidaan siirtää työtunnit projektinhallintajärjestelmästä taloushallinnon järjestelmään.
