PeerHood -verkon mobiililaitteiden akkutehon säästämiseksi siirretään mobiililaitteen verkkonaapuruston valvontatehtävät kiinteälle laitteelle. Valvontatehtävien siirto on tarkoitus tehdä silloin, kun laite pysyy paikallaan, esimerkiksi toimisto tiloissa. Laitteen pysyessä paikallaan voidaan verkkonaapurustoa seurata kiinteän laitteen resursseilla ja päivittää verkkomuutokset mobiililaitteelle tarvittaessa. Mobiililaitteen ollessa vain kuuntelutilassa laite säästää akkutehoa, koska sen ei tarvitse aktiivisesti lähettää dataa verkkolaitteillaan. Verkkolaitteet pysyvät lepotilassa ja odottavat vain tulevaa dataa. Verkkonaapuruston valvontatehtävien siirto ei kuitenkaan vaikuta käyttäjän palveluiden hyödyntämiseen, joten verkkolaitteen akkutehon säästö riippuu suuresti käyttäjän toimista, käyttäjä voi edelleen käyttää muiden PeerHood laitteiden palveluita tai tarjota omiaan.

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 strategy process is a method for strategy formulation and implementation. The strategy process is commonly used especially within bigger companies. It is important to link the strategy formulation and implementation. The objective of this thesis has been to find out improvement areas for the case company’s strategy process. The theoretical framework based on literature emphasizes on strategy process as a method for strategy formulation and implementation. The theoretical framework, several mainly ad hoc interviews and author’s observation were used as tools to analyze the case company’s strategy process. The hierarchy in between the various corporate levels provides the foundation to formulate and implement the strategies. These strategies include the corporate and strategic business area level strategies. The recommendations to improve the case company’s strategy process were formulated at corporate and strategic business area levels. These recommendations were formulated based on research and experience gained throughout the work. The role of strategic projects to implement the strategies more efficiently and organizational control over distribution were found as potential improvement areas. The resource allocation prioritizing towards the most important strategic projects was also an important improvement area.

During the past decades testing has matured from ad-hoc activity into being an integral part of the development process. The benefits of testing are obvious for modern communication systems, which operate in heterogeneous environments amongst devices from various manufacturers. The increased demand for testing also creates demand for tools and technologies that support and automate testing activities. This thesis discusses applicability of visualization techniques in the result analysis part of the testing process. Particularly, the primary focus of this work is visualization of test execution logs produced by a TTCN-3 test system. TTCN-3 is an internationally standardized test specification and implementation language. The TTCN-3 standard suite includes specification of a test logging interface and a graphical presentation format, but no immediate relationship between them. This thesis presents a technique for mapping the log events to the graphical presentation format along with a concrete implementation, which is integrated with the Eclipse Platform and the OpenTTCN Tester toolchain. Results of this work indicate that for majority of the log events, a visual representation may be derived from the TTCN-3 standard suite. The remaining events were analysed and three categories relevant in either log analysis or implementation of the visualization tool were identified: events indicating insertion of something into the incoming queue of a port, events indicating a mismatch and events describing the control flow during the execution. Applicability of the results is limited into the domain of TTCN-3, but the developed mapping and the implementation may be utilized with any TTCN-3 tool that is able to produce the execution log in the standardized XML format.

The computer is a useful tool in the teaching of upper secondary school physics, and should not have a subordinate role in students' learning process. However, computers and computer-based tools are often not available when they could serve their purpose best in the ongoing teaching. Another problem is the fact that commercially available tools are not usable in the way the teacher wants. The aim of this thesis was to try out a novel teaching scenario in a complicated subject in physics, electrodynamics. The didactic engineering of the thesis consisted of developing a computer-based simulation and training material, implementing the tool in physics teaching and investigating its effectiveness in the learning process. The design-based research method, didactic engineering (Artigue, 1994), which is based on the theoryof didactical situations (Brousseau, 1997), was used as a frame of reference for the design of this type of teaching product. In designing the simulation tool a general spreadsheet program was used. The design was based on parallel, dynamic representations of the physics behind the function of an AC series circuit in both graphical and numerical form. The tool, which was furnished with possibilities to control the representations in an interactive way, was hypothesized to activate the students and promote the effectiveness of their learning. An effect variable was constructed in order to measure the students' and teachers' conceptions of learning effectiveness. The empirical study was twofold. Twelve physics students, who attended a course in electrodynamics in an upper secondary school, participated in a class experiment with the computer-based tool implemented in three modes of didactical situations: practice, concept introduction and assessment. The main goal of the didactical situations was to have students solve problems and study the function of AC series circuits, taking responsibility for theirown learning process. In the teacher study eighteen Swedish speaking physics teachers evaluated the didactic potential of the computer-based tool and the accompanying paper-based material without using them in their physics teaching. Quantitative and qualitative data were collected using questionnaires, observations and interviews. The result of the studies showed that both the group of students and the teachers had generally positive conceptions of learning effectiveness. The students' conceptions were more positive in the practice situation than in the concept introduction situation, a setting that was more explorative. However, it turned out that the students' conceptions were also positive in the more complex assessment situation. This had not been hypothesized. A deeper analysis of data from observations and interviews showed that one of the students in each pair was more active than the other, taking more initiative and more responsibilityfor the student-student and student-computer interaction. These active studentshad strong, positive conceptions of learning effectiveness in each of the threedidactical situations. The group of less active students had a weak but positive conception in the first iv two situations, but a negative conception in the assessment situation, thus corroborating the hypothesis ad hoc. The teacher study revealed that computers were seldom used in physics teaching and that computer programs were in short supply. The use of a computer was considered time-consuming. As long as physics teaching with computer-based tools has to take place in special computer rooms, the use of such tools will remain limited. The affordance is enhanced when the physical dimensions as well as the performance of the computer are optimised. As a consequence, the computer then becomes a real learning tool for each pair of students, smoothly integrated into the ongoing teaching in the same space where teaching normally takes place. With more interactive support from the teacher, the computer-based parallel, dynamic representations will be efficient in promoting the learning process of the students with focus on qualitative reasoning - an often neglected part of the learning process of the students in upper secondary school physics.

Tämä tutkimus pyrkii määrittelemään itsenäisenä puolustushaarana toimivalle maavoimille sen tehtäviin soveltuvan verkostokeskeisyyttä ja joukkorakenteita tukevan tiedonsiirtojärjestelmän arkkitehtuurin. Tutkimus on luonteeltaan teoreettinen. Siinä analysoidaan yleistä sotilaallisten tiedonsiirtojärjestelmien kehitystä kylmästä sodasta lähtien, tiedonsiirtojärjestelmien kehitystä Yhdysvaltain ja Suomen maavoimissa sekä kaupallisten tiedonsiirtojärjestelmien kehitysnäkymiä. Analyysin pohjalta on laadittu arkkitehtuurikuvaus koostuen kahdeksasta PVTAKmäärittelyn mukaisesta näkymästä sekä esimerkki arkkitehtuurin soveltamisesta käytäntöön. Tämän työn tutkimusongelmana on, millainen maavoimien tiedonsiirtojärjestelmän arkkitehtuuri tukee tulevaisuudessa parhaiten verkostokeskeisyyttä ja yleistä teknistä kehitystä. Lisäksi tutkimuksessa selvitetään sotilaallisten tiedonsiirtojärjestelmien historian ja kehitysnäkymien vaikutusta arkkitehtuurin rakenteeseen. Tutkimusmenetelmänä työssä käytetään kirjallisuusanalyysia ja suunnittelua. Arkkitehtuurin laatiminen ja esimerkki arkkitehtuurin toteuttamisesta luokitellaan suunnitteluksi. Puolustusjärjestelmää valmistaudutaan käyttämään alue-, YETTS-, kriisinhallinta- ja informaatiosodassa. Keskeinen vaatimus on kyky toimia kaikissa näissä toimintaympäristöissä samalla kalustolla. Verkostokeskeisyyden toteuttamisen puolestaan todettiin vaativan suorituskykyistä, yhteensopivaa ja tietoturvallista tiedonsiirtojärjestelmää, joka takaa yhteydellisyyden taistelukentän toimijoiden kesken. Tällä tuetaan erityisesti verkostokeskeistä johtamista ja suunnittelua. Tiedonsiirtojärjestelmien kehityksen todettiin olevan kaikissa asevoimissa hidasta. Myös käytössä olevien ikääntyneiden järjestelmien kehityksen nopeuttaminen on osoittautunut haasteelliseksi hankintaprosessin luonteesta johtuen. Yhdysvaltain maavoimien tiedonsiirtojärjestelmissä hyödynnetään yhä runsaammin COTStekniikka, mutta taktiset johtamisyhteydet toteutetaan yhä useimmiten sotilasjärjestelmillä. Uusimmassa maavoimien järjestelmässä WIN-T:ssä korostuu kerroksellisuus (maa, ilma ja avaruus) ja tehtävän vaatimusten mukaan rakennettava järjestelmä. Sen merkittävä osa on myös JTRS-ohjelmistoradio kaikkine versioineen. Järjestelmän modulaarinen rakenne mahdollistaa jatkuvan osajärjestelmien kehittämisen teknisen kehityksen myötä. Suomen maavoimien tiedonsiirtojärjestelmät vaativat nykyisellään kehitystyötä, mutta ulkomaanoperaatioiden järjestelmiä voidaan pitää onnistuneina ja nykyaikaisina. Tärkeänä nähdäänkin kaikkien joukkotyyppien järjestelmäkehityksen yhdistäminen paremman suorituskyvyn ja yhteensopivuuden saavuttamiseksi. Kaupallisten tiedonsiirtojärjestelmien sotilaskäytön todettiin sisältävän monia haasteita sekä mahdollisuuksia. Kehityksen eteneminen kohti NGN-verkkoja kuitenkin tukee verkostokeskeisyyttä ja sotilassovelluksia. Tällä hetkellä mielenkiintoisimpia sovelluksia ovat ohjelmistoradio ja langattomat laajakaistaiset ad hoc -datansiirtojärjestelmät. Maavoimien tiedonsiirtojärjestelmän arkkitehtuuri on modulaarinen rakentuen siirtojärjestelmistä, käyttäjäympäristö- ja järjestelmäsolmuista sekä yhtenäisestä ohjaus- ja valvontajärjestelmästä. Siirtojärjestelmiä ovat PAN- (henkilökohtaiset), LAN- (lähi), LOS- (suoran yhteyden), BLOS- (epäsuoran yhteyden) ja runkoverkkojärjestelmät. Solmuja ovat esikunta- , komentopaikka- ja liikkuvan tilaajan sekä järjestelmäsolmu. Siirtoteitä ja solmuja kyetään ohjaamaan sekä valvomaan yhtenäisellä ohjaus- ja valvontajärjestelmällä. Keskeistä kokonaisuudessa on IP-protokollan laaja hyödyntäminen. Arkkitehtuuria voidaan soveltaa kaikille joukkotyypeille. Sen toteutuksen tekniikat ja järjestelmät voivat olla COTS:ia tai sotilaallista tekniikkaa. Toteutetut järjestelmät ovat joukkojen erilaisesta luonteesta ja toiminnan vaatimuksista johtuen mahdollisesti hyvinkin erilaisia.

The aim of this study was to develop a theoretical model for information integration to support the deci¬sion making of intensive care charge nurses, and physicians in charge – that is, ICU shift leaders. The study focused on the ad hoc decision-making and immediate information needs of shift leaders during the management of an intensive care unit’s (ICU) daily activities. The term ‘ad hoc decision-making’ was defined as critical judgements that are needed for a specific purpose at a precise moment with the goal of ensuring instant and adequate patient care and a fluent flow of ICU activities. Data collection and research analysis methods were tested in the identification of ICU shift leaders’ ad hoc decision-making. Decision-making of ICU charge nurses (n = 12) and physicians in charge (n = 8) was observed using a think-aloud technique in two university-affiliated Finnish ICUs for adults. The ad hoc decisions of ICU shift leaders were identified using an application of protocol analysis. In the next phase, a structured online question¬naire was developed to evaluate the immediate information needs of ICU shift leaders. A national survey was conducted in all Finnish, university-affiliated hospital ICUs for adults (n = 17). The questionnaire was sent to all charge nurses (n = 515) and physicians in charge (n = 223). Altogether, 257 charge nurses (50%) and 96 physicians in charge (43%) responded to the survey. The survey was also tested internationally in 16 Greek ICUs. From Greece, 50 charge nurses out of 240 (21%) responded to the survey. A think-aloud technique and protocol analysis were found to be applicable for the identification of the ad hoc decision-making of ICU shift leaders. During one day shift leaders made over 200 ad hoc decisions. Ad hoc decisions were made horizontally, related to the whole intensive care process, and vertically, concerning single intensive care incidents. Most of the ICU shift leaders’ ad hoc decisions were related to human resources and know-how, patient information and vital signs, and special treatments. Commonly, this ad hoc decision-making involved several multiprofessional decisions that constituted a bundle of immediate decisions and various information needs. Some of these immediate information needs were shared between the charge nurses and the physicians in charge. The majority of which concerned patient admission, the organisation and management of work, and staff allocation. In general, the information needs of charge nurses were more varied than those of physicians. It was found that many ad hoc deci-sions made by the physicians in charge produced several information needs for ICU charge nurses. This meant that before the task at hand was completed, various kinds of information was sought by the charge nurses to support the decision-making process. Most of the immediate information needs of charge nurses were related to the organisation and management of work and human resources, whereas the information needs of the physicians in charge mainly concerned direct patient care. Thus, information needs differ between professionals even if the goal of decision-making is the same. The results of the international survey confirmed these study results for charge nurses. Both in Finland and in Greece the information needs of charge nurses focused on the organisation and management of work and human resources. Many of the most crucial information needs of Finnish and Greek ICU charge nurses were common. In conclusion, it was found that ICU shift leaders make hundreds of ad hoc decisions during the course of a day related to the allocation of resources and organisation of patient care. The ad hoc decision-making of ICU shift leaders is a complex multi-professional process, which requires a lot of immediate information. Real-time support for information related to patient admission, the organisation and man¬agement of work, and allocation of staff resources is especially needed. The preliminary information integration model can be applied when real-time enterprise resource planning systems are developed for intensive care daily management

The significance of services as business and human activities has increased dramatically throughout the world in the last three decades. Becoming a more and more competitive and efficient service provider while still being able to provide unique value opportunities for customers requires new knowledge and ideas. Part of this knowledge is created and utilized in daily activities in every service organization, but not all of it, and therefore an emerging phenomenon in the service context is information awareness. Terms like big data and Internet of things are not only modern buzz-words but they are also describing urgent requirements for a new type of competences and solutions. When the amount of information increases and the systems processing information become more efficient and intelligent, it is the human understanding and objectives that may get separated from the automated processes and technological innovations. This is an important challenge and the core driver for this dissertation: What kind of information is created, possessed and utilized in the service context, and even more importantly, what information exists but is not acknowledged or used? In this dissertation the focus is on the relationship between service design and service operations. Reframing this relationship refers to viewing the service system from the architectural perspective. The selected perspective allows analysing the relationship between design activities and operational activities as an information system while maintaining the tight connection to existing service research contributions and approaches. This type of an innovative approach is supported by research methodology that relies on design science theory. The methodological process supports the construction of a new design artifact based on existing theoretical knowledge, creation of new innovations and testing the design artifact components in real service contexts. The relationship between design and operations is analysed in the health care and social care service systems. The existing contributions in service research tend to abstract services and service systems as value creation, working or interactive systems. This dissertation adds an important information processing system perspective to the research. The main contribution focuses on the following argument: Only part of the service information system is automated and computerized, whereas a significant part of information processing is embedded in human activities, communication and ad-hoc reactions. The results indicate that the relationship between service design and service operations is more complex and dynamic than the existing scientific and managerial models tend to view it. Both activities create, utilize, mix and share information, making service information management a necessary but relatively unknown managerial task. On the architectural level, service system -specific elements seem to disappear, but access to more general information elements and processes can be found. While this dissertation focuses on conceptual-level design artifact construction, the results provide also very practical implications for service providers. Personal, visual and hidden activities of service, and more importantly all changes that take place in any service system have also an information dimension. Making this information dimension visual and prioritizing the processed information based on service dimensions is likely to provide new opportunities to increase activities and provide a new type of service potential for customers.

End-user development is a very common but often largely overlooked phenomenon in information systems research and practice. End-user development means that regular people, the end-users of software, and not professional developers are doing software development. A large number of people are directly or indirectly impacted by the results of these non-professional development activities. The numbers of users performing end-user development activities are difficult to ascertain precisely. But it is very large, and still growing. Computer adoption is growing towards 100% and many new types of computational devices are continually introduced. In addition, other devices not previously programmable are becoming so. This means that, at this very moment, hundreds of millions of people are likely struggling with development problems. Furthermore, software itself is continually being adapted for more flexibility, enabling users to change the behaviour of their software themselves. New software and services are helping to transform users from consumers to producers. Much of this is now found on-line. The problem for the end-user developer is that little of this development is supported by anyone. Often organisations do not notice end-user development and consequently neither provide support for it, nor are equipped to be able to do so. Many end-user developers do not belong to any organisation at all. Also, the end-user development process may be aggravating the problem. End-users are usually not really committed to the development process, which tends to be more iterative and ad hoc. This means support becomes a distant third behind getting the job done and figuring out the development issues to get the job done. Sometimes the software itself may exacerbate the issue by simplifying the development process, deemphasising the difficulty of the task being undertaken. On-line support could be the lifeline the end-user developer needs. Going online one can find all the knowledge one could ever need. However, that does still not help the end-user apply this information or knowledge in practice. A virtual community, through its ability to adopt the end-user’s specific context, could surmount this final obstacle. This thesis explores the concept of end-user development and how it could be supported through on-line sources, in particular virtual communities, which it is argued here, seem to fit the end-user developer’s needs very well. The experiences of real end-user developers and prior literature were used in this process. Emphasis has been on those end-user developers, e.g. small business owners, who may have literally nowhere to turn to for support. Adopting the viewpoint of the end-user developer, the thesis examines the question of how an end-user could use a virtual community effectively, improving the results of the support process. Assuming the common situation where the demand for support outstrips the supply.

Business intelligence (BI) is an information process that includes the activities and applications used to transform business data into valuable business information. Today’s enterprises are collecting detailed data which has increased the available business data drastically. In order to meet changing customer needs and gain competitive advantage businesses try to leverage this information. However, IT departments are struggling to meet the increased amount of reporting needs. Therefore, recent shift in the BI market has been towards empowering business users with self-service BI capabilities. The purpose of this study was to understand how self-service BI could help businesses to meet increased reporting demands. The research problem was approached with an empirical single case study. Qualitative data was gathered with a semi-structured, theme-based interview. The study found out that case company’s BI system was mostly used for group performance reporting. Ad-hoc and business user-driven information needs were mostly fulfilled with self-made tools and manual work. It was felt that necessary business information was not easily available. The concept of self-service BI was perceived to be helpful to meet such reporting needs. However, it was found out that the available data is often too complex for an average user to fully understand. The respondents felt that in order to self-service BI to work, the data has to be simplified and described in a way that it can be understood by the average business user. The results of the study suggest that BI programs struggle in meeting all the information needs of today’s businesses. The concept of self-service BI tries to resolve this problem by allowing users easy self-service access to necessary business information. However, business data is often complex and hard to understand. Self-serviced BI has to overcome this challenge before it can reach its potential benefits.

Tavoitteena on lisäksi saada kustannuksia pienemmäksi yhtenäistämällä järjestelmäympäristöjä ja BI-työkaluja kuten myös toimintamalleja. Työssä tehdään kirjallisuuskatsaus ja haastatellaan asiantuntijoita kolmessa yrityksessä. Tutkimuksen perusteella voidaan todeta, että liiketoiminnan BI-tarpeita kannattaa mahdollistaa eri tasoilla perusraportoinnista Ad-hoc –raportointiin ja edistyneeseen analytiikkaan huomioimalla nämä toimintamalleissa ja järjestelmäarkkitehtuurissa. BICC:n perustamisessa liiketoimintatarpeisiin vastaaminen on etusijalla.
