Free and open source software development is an alternative to traditional software engineering as an approach to the development of complex software systems. It is a way of developing software based on geographically distributed teams of volunteers without apparent central plan or traditional mechanisms of coordination. The purpose of this thesis is to summarize the current knowledge about free and open source software development and explore the ways on which further understanding on it could be gained. The results of research on the field as well as the research methods are introduced and discussed. Also adapting software process metrics to the context of free and open source software development is illustrated and the possibilities to utilize them as tools to validate other research are discussed.

The history of software development in a somewhat systematical way has been performed for half a century. Despite this time period, serious failures in software development projects still occur. The pertinent mission of software project management is to continuously achieve more and more successful projects. The application of agile software methods and more recently the integration of Lean practices contribute to this trend of continuous improvement in the software industry. One such area warranting proper empirical evidence is the operational efficiency of projects. In the field of software development, Kanban as a process management method has gained momentum recently, mostly due to its linkages to Lean thinking. However, only a few empirical studies investigate the impacts of Kanban on projects in that particular area. The aim of this doctoral thesis is to improve the understanding of how Kanban impacts on software projects. The research is carried out in the area of Lean thinking, which contains a variety of concepts including Kanban. This article-type thesis conducts a set of case studies expanded with the research strategy of quasi-controlled experiment. The data-gathering techniques of interviews, questionnaires, and different types of observations are used to study the case projects, and thereby to understand the impacts of Kanban on software development projects. The research papers of the thesis are refereed, international journal and conference publications. The results highlight new findings regarding the application of Kanban in the software context. The key findings of the thesis suggest that Kanban is applicable to software development. Despite its several benefits reported in this thesis, the empirical evidence implies that Kanban is not all-encompassing but requires additional practices to keep development projects performing appropriately. Implications for research are given, as well. In addition to these findings, the thesis contributes in the area of plan-driven software development by suggesting implications both for research and practitioners. As a conclusion, Kanban can benefit software development projects but additional practices would increase its potential for the projects.

Although previous research has recognised adaptation as a central aspect in relationships, the adaptation of the sales process to the buying process has not been studied. Furthermore, the linking of relationship orientation as mindset with adaptation as a strategy and forming the means has not been elaborated upon in previous research. Adaptation in the context of relationships has mostly been studied in relationship marketing. In sales and sales management research, adaptation has been studied with reference to personal selling. This study focuses on adaptation of the sales process to strategically match it to the buyer’s mindset and buying process. The purpose of this study is to develop a framework for strategic adaptation of the seller’s sales process to match the buyer’s buying process in a business-to-business context to make sales processes more relationship oriented. In order to arrive at a holistic view of adaptation of the sales process during relationship initiation, both the seller and buyer are included in an extensive case analysed in the study. However, the selected perspective is primarily that of the seller, and the level focused on is that of the sales process. The epistemological perspective adopted is constructivism. The study is a qualitative one applying a retrospective case study, where the main sources of information are in-depth semi-structured interviews with key informants representing the counterparts at the seller and the buyer in the software development and telecommunications industries. The main theoretical contributions of this research involve targeting a new area in the crossroads of relationship marketing, sales and sales management, and buying and purchasing by studying adaptation in a business-to-business context from a new perspective. Primarily, this study contributes to research in sales and sales management with reference to relationship orientation and strategic sales process adaptation. This research fills three research gaps. Firstly, linking the relationship orientation mindset with adaptation as strategy. Secondly, extending adaptation in sales from adaptation in selling to strategic adaptation of the sales process. Thirdly, extending adaptation to include facilitation of adaptation. The approach applied in the study, systematic combining, is characterised by continuously moving back and forth between theory and empirical data. The framework that emerges, in which linking mindset with strategy with mindset and means forms a central aspect, includes three layers: purchasing portfolio, seller-buyer relationship orientation, and strategic sales process adaptation. Linking the three layers enables an analysis of where sales process adaptation can make a contribution. Furthermore, implications for managerial use are demonstrated, for example how sellers can avoid the ‘trap’ of ad-hoc adaptation. This includes involving the company, embracing the buyer’s purchasing portfolio, understanding the current position that the seller has in this portfolio, and possibly educating the buyer about advantages of adopting a relationship-oriented approach.

Poor pharmacokinetics is one of the reasons for the withdrawal of drug candidates from clinical trials. There is an urgent need for investigating in vitro ADME (absorption, distribution, metabolism and excretion) properties and recognising unsuitable drug candidates as early as possible in the drug development process. Current throughput of in vitro ADME profiling is insufficient because effective new synthesis techniques, such as drug design in silico and combinatorial synthesis, have vastly increased the number of drug candidates. Assay technologies for larger sets of compounds than are currently feasible are critically needed. The first part of this work focused on the evaluation of cocktail strategy in studies of drug permeability and metabolic stability. N-in-one liquid chromatography-tandem mass spectrometry (LC/MS/MS) methods were developed and validated for the multiple component analysis of samples in cocktail experiments. Together, cocktail dosing and LC/MS/MS were found to form an effective tool for increasing throughput. First, cocktail dosing, i.e. the use of a mixture of many test compounds, was applied in permeability experiments with Caco-2 cell culture, which is a widely used in vitro model for small intestinal absorption. A cocktail of 7-10 reference compounds was successfully evaluated for standardization and routine testing of the performance of Caco-2 cell cultures. Secondly, cocktail strategy was used in metabolic stability studies of drugs with UGT isoenzymes, which are one of the most important phase II drug metabolizing enzymes. The study confirmed that the determination of intrinsic clearance (Clint) as a cocktail of seven substrates is possible. The LC/MS/MS methods that were developed were fast and reliable for the quantitative analysis of a heterogenous set of drugs from Caco-2 permeability experiments and the set of glucuronides from in vitro stability experiments. The performance of a new ionization technique, atmospheric pressure photoionization (APPI), was evaluated through comparison with electrospray ionization (ESI), where both techniques were used for the analysis of Caco-2 samples. Like ESI, also APPI proved to be a reliable technique for the analysis of Caco-2 samples and even more flexible than ESI because of the wider dynamic linear range. The second part of the experimental study focused on metabolite profiling. Different mass spectrometric instruments and commercially available software tools were investigated for profiling metabolites in urine and hepatocyte samples. All the instruments tested (triple quadrupole, quadrupole time-of-flight, ion trap) exhibited some good and some bad features in searching for and identifying of expected and non-expected metabolites. Although, current profiling software is helpful, it is still insufficient. Thus a time-consuming largely manual approach is still required for metabolite profiling from complex biological matrices.

Requirements engineering is an important phase in software development where customer's needs and expectations are transformed into a software requirements specification. The requirements specification can be considered as an agreement between the customer and the developer where both parties agree on the expected system features and behaviour. However, requirements engineers must deal with a variety of issues that complicate the requirements process. The communication gap between the customer and the developers is among typical reasons for unsatisfactory requirements. In this thesis we study how the use case technique could be used in requirements engineering in bridging the communication gap between the customer and development team. We also discuss how a use case description can be use cases can be used as a basis for acceptance test cases.

For the past twenty years, several indicator sets have been produced on international, national and regional levels. Most of the work has concentrated on the selection of the indicators and on collection of the pertinent data, but less attention has been given to the actual users and their needs. This dissertation focuses on the use of sustainable development indicator sets. The dissertation explores the reasons that have deterred the use of the indicators, discusses the role of sustainable development indicators in a policy-cycle and broadens the view of use by recognising three different types of use. The work presents two indicator development processes: The Finnish national sustainable development indicators and the socio-cultural indicators supporting the measurement of eco-efficiency in the Kymenlaakso Region. The sets are compared by using a framework created in this work to describe indicator process quality. It includes five principles supported by more specific criteria. The principles are high policy relevance, sound indicator quality, efficient participation, effective dissemination and long-term institutionalisation. The framework provided a way to identify the key obstacles for use. The two immediate problems with current indicator sets are that the users are unaware of them and the indicators are often unsuitable to their needs. The reasons for these major flaws are irrelevance of the indicators to the policy needs, technical shortcomings in the context and presentation, failure to engage the users in the development process, non-existent dissemination strategies and lack of institutionalisation to promote and update the indicators. The importance of the different obstacles differs among the users and use types. In addition to the indicator projects, materials used in the dissertation include 38 interviews of high-level policy-makers or civil servants close to them, statistics of the national indicator Internet-page downloads, citations of the national indicator publication, and the media coverage of both indicator sets. According to the results, the most likely use for a sustainable development indicator set by policy-makers is to learn about the concept. Very little evidence of direct use to support decision-making was available. Conceptual use is also common for other user groups, namely the media, civil servants, researchers, students and teachers. Decision-makers themselves consider the most obvious use for the indicators to be the promotion of their own views which is a form of legitimising use. The sustainable development indicators have different types of use in the policy cycle and most commonly expected instrumental use is not very likely or even desirable at all stages. Stages of persuading the public and the decision-makers about new problems as well as in formulating new policies employ legitimising use. Learning by conceptual use is also inherent to policy-making as people involved learn about the new situation. Instrumental use is most likely in policy formulation, implementation and evaluation. The dissertation is an article dissertation, including five papers that are published in scientific journals and an extensive introductory chapter that discusses and weaves together the papers.

The driving force behind this study is the gap between the reality of the firms engaged in project business and the available studies covering project management and business process development. Previous studies show that project-based organizations were ‘immature’ in terms of the project-management ‘maturity model’, as few firms were found to be optimizing processes. Even within those, very little attention was paid to combine inter-organizational and intra-organizational perspectives. In this study an effort is made to elaborate some thoughts and views on project management, which interrelate firms’ external and internal activities. In line with the integration, the dissertation uses an approach to the management of project-business interdependencies in the networks of actors, activities and resources. Firstly, the study develops an understanding for inter-organizational perspectives by exploring the complementarities of process activities in the basic development of project business. It presents a framework that is elaborated on the basis of the reciprocal interactions of activities within and outside the organization—thus providing a coherent basis for continuous business-process improvement. In addition, the study presents new tools that can be used to develop project-business processes in each of its functional areas. The research demonstrates how project-business activities can be optimized using the right resources at the right time with the right actors and the right actions. The selected five articles included in this dissertation explain the basic framework for the development of project business. Each paper covers various aspects of inter-organizational and intra-organizational perspectives for project management. The study develops a valuable and procedural model for business-process improvement using the Delphi method that can be used not only in academia but also as a guide for practitioners that takes them through a series of well-defined steps when making informed, consistent and efficient changes to their business processes.

The present study concentrates on a small – but important – area of marketing: offering development within the service sector, more exactly the restaurant sector. The empirical part of the study has been carried out in the Helsinki metropolitan area using six successful restaurants. First, a conceptual offering development model is developed based on how the management perceives the offering development processes. Second, customer perceptions of offerings and management beliefs about how the customers perceive the offerings are analysed. Finally, an extended offering development model is created based on the management perceptions (the first model) as well as on observed gaps between customer perceptions of offerings and management beliefs about the customer perceptions. The study reveals that customer perceptions and management beliefs are rather similar but also that some differences exist. These differences are taken into account in the extended offering development model (the second model). The empirical data was collected through interviews and surveys. All together 393 customers and 14 managers participated in the study. The study suggests that successful offering development has to be closely connected with the general strategy of the company. A shared vision within the company in combination with a systematic strategic offering development process create a sound basis for the practical development work. The main contribution of the study is the extended offering development model forming a framework for further studies within the area.

Service researchers have repeatedly claimed that firms should acquire customer information in order to develop services that fit customer needs. Despite this, studies that would concentrate on the actual use of customer information in service development are lacking. The present study fulfils this research gap by investigating information use during a service development process. It demonstrates that use is not a straightforward task that automatically follows the acquisition of customer information. In fact, out of the six identified types of use, four represent non usage of customer information. Hence, the study demonstrates that the acquisition of customer information does not guarantee that the information will actually be used in development. The current study used an ethnographic approach. Consequently, the study was conducted in the field in real time over an extensive period of 13 months. Participant observation allowed direct access to the investigated phenomenon, i.e. the different types of use by the observed development project members were captured while they emerged. In addition, interviews, informal discussions and internal documents were used to gather data. A development process of a bank’s website constituted the empirical context of the investigation. This ethnography brings novel insights to both academia and practice. It critically questions the traditional focus on the firm’s acquisition of customer information and suggests that this focus ought to be expanded to the actual use of customer information. What is the point in acquiring costly customer information if it is not used in the development? Based on the findings of this study, a holistic view on customer information, “information in use” is generated. This view extends the traditional view of customer information in three ways: the source, timing and form of data collection. First, the study showed that the customer information can come explicitly from the customer, from speculation among the developers or it can already exist implicitly. Prior research has mainly focused on the customer as the information provider and the explicit source to turn to for information. Second, the study identified that the used and non-used customer information was acquired both previously, and currently within the time frame of the focal development process, as well as potentially in the future. Prior research has primarily focused on the currently acquired customer information, i.e. within the timeframe of the development process. Third, the used and non-used customer information was both formally and informally acquired. In prior research a large number of sophisticated formal methods have been suggested for the acquisition of customer information to be used in development. By focusing on “information in use”, new knowledge on types of customer information that are actually used was generated. For example, the findings show that the formal customer information acquired during the development process is used less than customer information already existent within the firm. With this knowledge at hand, better methods to capture this more usable customer information can be developed. Moreover, the thesis suggests that by focusing stronger on use of customer information, service development processes can be restructured in order to facilitate the information that is actually used.

In the context of health care, information technology (IT) has an important role in the operational infrastructure, ranging from business management to patient care. An essential part of the system is medication management in inpatient and outpatient care. Community pharmacists strategy has been to extend practice responsibilities beyond dispensing towards patient care services. Few studies have evaluated the strategic development of IT systems to support this vision. The objectives of this study were to assess and compare independent Finnish community pharmacy owners and staff pharmacists priorities concerning the content and structure of the next generation of community pharmacy IT systems, to explore international experts visions and strategic views on IT development needs in relation to services provided in community pharmacies, to identify IT innovations facilitating patient care services and to evaluate their development and implementation processes, and to assess community pharmacists readiness to adopt innovations. This study applied both qualitative and quantitative methods. A qualitative personal interview of 14 experts in community pharmacy services and related IT from eight countries and a national survey of Finnish community pharmacy owners (mail survey, response rate 53%, n=308), and of a representative sample of staff pharmacists (online survey, response rate 22%, n=373) were conducted. Finnish independent community pharmacy owners gave priority to logistical functions but also to those related to medication information and patient care. The managers and staff pharmacists have different views of the importance of IT features, reflecting their different professional duties in the community pharmacy. This indicates the need for involving different occupation groups in planning the new IT systems for community pharmacies. A majority of the international experts shared the vision of community pharmacy adopting a patient care orientation; supported by IT-based documentation, new technological solutions, access to information, and shared patient data. Community pharmacy IT innovations were rare, which is paradoxical because owners and staff pharmacists perception of their innovativeness was seen as being high. Community pharmacy IT systems development processes usually had not undergone systematic needs assessment research beforehand or evaluation after the implementation and were most often coordinated by national governments without subsequent commercialization. Specifically, community pharmacy IT developments lack research, organization, leadership and user involvement in the process. Those responsible for IT development in the community pharmacy sector should create long-term IT development strategies that are in line with community pharmacy service development strategies. This could provide systematic guidance for future projects to ensure that potential innovations are based on a sufficient understanding of pharmacy practice problems that they are intended to solve, and to encourage strong leadership in research, development of innovations so that community pharmacists potential innovativeness is used, and that professional needs and strategic priorities will be considered even if the development process is led by those outside the profession.

Nature, science and technology. The image of Finland through popular enlightenment texts 1870-1920 This doctoral thesis looks at how Finnish popular enlightenment texts published between 1870 and 1920 took part in the process of forming a genuine Finnish national identity. The same process was occurring in other Nordic countries at the time and the process in Finland was in many ways influenced by them, particularly Sweden. In Finland the political realities under Russian rule especially during the Russification years, and the fact that its history was considered to be short compared to other European countries, made this nation-building process unique. The undertaking was led by members of the national elite, influential in the cultural, academic as well as political arenas, who were keen to support the foundation of a modern Finnish identity. The political realities and national philosophy of history necessitated a search for elements of identity in nature and the Finnish landscape, which were considered to have special national importance: Finland was very much determined as a political entity on the basis of its geography and nature. Nature was also used as means of taking a cultural or political view in terms of, for example, geographical facts such as the nation s borders or the country s geographical connections to Western Europe. In the building of a proper national identity the concept of nature was not, however, static, but was more or less affected by political and economic progress in society. This meant that nature, or the image of the national landscape, was no longer seen only as a visual image of the national identity, but also as a source of science, technology and a prosperous future. The role of technology in this process was very much connected to the ability to harness natural resources to serve national interests. The major change in this respect had occurred by the early 20th century, when indisputable scientific progress altered the relationship between nature and technology. Concerning technology, the thesis is mainly interested in the large and at the time modern technological manifestations, such as railways, factories and industrial areas in Finland. Despite the fact that the symbiosis between national nature and international but successfully localized technology was in Finnish popular enlightenment literature depicted mostly as a national success story, concerns began to arise already in last years of the 19th century. It was argued that the emerging technology would eventually destroy Finland s natural environment, and therefore the basis of its national identity. The question was not how to preserve nature through natural science, but more how to conserve such natural resources and images that were considered to be the basis of national identity and thus of the national history. National parks, isolated from technology, and distant enough so as to have no economic value, were considered the solution to the problem. Methodologically the thesis belongs to the genre of science and technology studies, and offers new viewpoints with regard to both the study of Finnish popular enlightenment literature and the national development process as a whole.

This study deals with the formation of the idea of research and development (r&d) activity at one particular university of applied sciences in Finland. In this study I proceed from examining the conceptions of management regarding r&d-activities to exploring the development of the complex concept that guides these r&d-activities. The aim of this study is, first, to describe conceptions of r&d-activities, and then, second, to describe the formation of a new concept for r&d-activities in one field of study at the university of applied sciences. I used phenomenographic analysis to elucidate the conceptions and collected the data in interviews of personnel (22) who belong to the management of the university of applied sciences. The data for analysing the obstacles faced and the ways of overcoming them during the formation process of the new concept consist of the video-recorded material from ten change laboratory sessions held for the specific field of study at the university of applied sciences. In researching the formation of the concept of the activity, such research and analysis methods are used in which the concept is understood as a material construction, and with the help of which one can work out the formation of the concept during the development process. When the systematic development of the r&d-work was underway, the management of the university of applied sciences held differing views regarding the content, target, factors and organisation of the r&d-activities, as well as regarding the position of dissertations as a part of r&d-activity. Obstacles for developing rd concerned the unclear object and outcomes of the new activity, not having the tools (such as adequate know-how) for the new activity and not having found the necessary solutions for the distribution of work. In addition the rules that quide the activities of the university of applied sciences did not support working according to the new way. To improve r&d-activity, the school’s management defined three development strategies to encourage adequate rd-activity to support working life, regional development and learning. The strategies were based on the expansion of existing methods, such as service activities, dissertation work and the research activities of the teachers. Of the three possible routes, the concept of dissertation in this study was expanded to integrate the services of organisation development and the occupational growth of the students. A group of teachers in the field of social and health studies participated in the development work. The change laboratory method was used as a tool for this work. Analysis of the cognitive trails indicated that, in addition to the cycle of expansive learning activities, microcycles with different purposes can exist. According to Cussins (1992), something already in existence in each microcycle is destabilised, and something else is stabilised to replace it. In this study three microcycles were identified, during which the teachers first destabilised the existing concepts of dissertation work that guided their thinking, and then began to use new concepts to structure their thinking. Secondly, they undermined the existing concepts with material structure that defined their practical work, and developed new practical models to replace them. Thirdly, the problems accumulating in researching and testing the new activities caused the developers to destabilise the r&d-strategies of the university of applied sciences and to define a new conceptual model for r&d-work in the field. During this third cycle, the teachers developed a research arena model, which was a significant expansive innovation. In the cognitive trails developing the new concept for the r&d-activity, the teachers indeed faced the obstacles the management had described as their conceptions. These obstacles manifested themselves as contradictions. During the development process, the nature of the obstacles (i.e. contradictions) changed as the development proceeded. Solving the first and second degree contradictions highlighted the third and fourth degree contradictions. To overcome the obstacles, the teachers had to to articulate the value and motive of the development work throughout the development process. Developing the new concept for r&d-activity required many reconfigurations of practical solutions to overcome the obstacles. Developing the new concept for r&d-activity, both at the level of representations and of new practices, requires universities of applied sciences to adopt new methods in which the actors are partake in construction of new concepts of activity through adequate discussion, analysis and debate. R&d -activity can progress, if instead of implementing partial solutions, the totality of the activities (i.e. the group of partial solutions acting together) will be constructed. The development of the activity system requires many simultaneous changes as well as wide-ranging know-how and discussion related to these changes. What is perhaps most important, however, is that the group of developers mature into a determined collective actor which can engage in many agentive actions. The development of the agency is fundamental to progress.

Working life is changing. The core of the change is change in the production and service concepts of organizations. Changes at work are connected to problems in the well-being of employees. To respond to this challenge, occupational health care must develop a course of action. A group of occupational health care units has developed new activity theory-based methods, the object of which is to change the service concept of occupational health care. The focus is on the changes and disturbances in work activity. My aim was to study this development from the perspective of knowledge management; to clarify directors'/ managers' conceptions of the content and object of their managerial work and the tensions included in these conceptions; to examine the learning process involved in these methods and to bring to light the problems, developmental needs and challenges during the implementation and consolidation phases of the process. This was a case study which included 10 occupational health care units using or being trained to use activity theory-based methods. My data consisted of interviews with directors/managers and recordings of the meetings; 20 directors/ managers are represented; I interviewed seven directors/ managers who represented four units. Directors'/ managers' conceptions of the content and object of managerial work were divided into eight categories of description, which I connected to the historical forms of organizations and types of management. Intuitive and rational management are historically older forms of management. The categories of description representing intuitive and rational management contained many internal tensions, i.e. they do not satisfy the demands of the environment. On the other hand, the categories of description which represented management by results and the control of the development process contained very few or no tensions at all; they are effective in the present environment of occupational health care. The learning process of activity theory-based methods has been expansive in nature. The occupational health care units studied are in different phases of the learning process, and these processes have been different. In three units the focus was on work development; in one unit the focus was on development of the service concept. The most central problems, challenges and developmental needs during the implementation phase were related to learning and spreading of methods inside one's own unit, and during the consolidation phase to working with partners.

A Journey in the Landscape of Sustainable School Development “A Journey in the Landscape of Sustainable School Development” is a story of the Sorrila School development process. This research deals with a school development project as a process, and as a part of international projects on Education for Sustainable Development, with ENSI (Environment and School Initiatives) being the most important. The main purpose of the study was to analyze the change process as a general phenomenon as well as the learning connected to it. The research describes the development period 2001–2008 at the Sorrila Primary school. The research questions are as follows: 1. What did pupils learn during the research and development period? 2. How did the coordinating teacher develop personally? 3. How were the ENSI targets and other closely linked projects reached? 4. What was the feedback from the pupils, their parents and other teachers at the school? 5. How did the developing process proceed in 2001–2008? The method used was integrating action research, which also had ethnographical elements. Narrative was the form of the data as well as the manner of reporting. The method as a whole was integrating, ethnographical action research as a story. The research data consisted mostly of Knowledge Forum notes written by the teacher-researcher. Knowledge Forum is an Internetbased collaborative knowledge-building programme. Pupils’, parents’ and other teachers’ feedback, newspaper articles and students’ writings complied the data, which consists of material from seven years. Sustainable development was the basis of the school improvement. The targets of the United Nations Decade of Education for Sustainable Development (2005–2014) were part of the development projects. According to the research results the school was seen as part of complex systems where manifold and interactive learning took place. The learning of pupils, teachers and the school as a community can be characterised socioculturally. The school was able to reach a level of collaborative transformative learning. As well as several concrete projects, such as Comenius school project, school development consisted of networking at many levels. Along with the projects and networking, the school was able to apply the pedagogy of connection, by carrying out integrative and cross-disciplinary themes and using various learning and teaching methods. International cooperation was a natural part of the work. A figure of Aunt Green, the role model of the teacher researcher, was an innovation which resembled a change agent. The other role of the teacherresearcher as a coordinator, was important for her own professional development. According to the results the change process, which relied on sustainable school development, led the school along a road of positive renewals. It was not a series of projects but an ongoing process. The objectives of the international projects were accomplished to a great extent during the research period. According to the principles of action research, the main results were put forward in order to help others to develop their schools. Frictions and problems as well as positive experiences and rejecting dualities were seen as change forces. Keywords: education for sustainable development (ESD), sustainable school development, teacher professional development, integrating, pedagogy of connection, transformative learning

Usability testing is a productive and reliable method for evaluating the usability of software. Planning and implementing the test and analyzing its results is typically considered time-consuming, whereas applying usability methods in general is considered difficult. Because of this, usability testing is often priorized lower than more concrete issues in software engineering projects. Intranet Alma is a web service, users of which consist of students and personnel of the University of Helsinki. Alma was published in 2004 at the opening ceremony of the university. It has 45 000 users, and it replaces several former university network services. In this thesis, the usability of intranet Alma is evaluated with usability testing. The testing method applied has been lightened to make its taking into use as easy as possible. In the test, six students each tried to solve nine test tasks with Alma. As a result concrete usability problems were described in the final test report. Goal-orientation was given less importance in the applied usability testing. In addition, the system was tested only with test users from the largest user group. Usability test found general usability problems that occurred no matter the task or the user. However, further evaluation needs to be done: in addition to the general usability problems, there are task-dependent problems, solving of which requires thorough gathering of users goals. In the basic structure and central functionality of Alma, for example in navigation, there are serious and often repeating usability problems. It would be of interest to verify the designed user interface solutions to these problems before taking them into use. In the long run, the goals of the users, that the software is planned to support, are worth gathering, and the software development should be based on these goals.
