RFID-teknologia ja kulunvalvontajärjestelmät

RFID on radioaaltoja hyväksikäyttävä langaton kommunikointitekniikka, jota käytetään tunnistamaan tunnisteella merkittyjä esineitä tai ihmisiä yksilöinä. RFID on jo pitkään ollut tunnettu tekniikka, mutta vasta viime vuosikymmeninä sitä on alettu hyödyntämään kaupallisesti eri sovellusaloilla. Kandidaatintyön tarkoituksena on tehdä yleiskatsaus RFID:n historiaan, järjestelmien osiin ja niiden toimintaan sekä kartoittaa RFID-markkinoiden nykytilaa ja lähitulevaisuutta sekä globaalilta kannalta että Suomessa. Lopuksi työssä tarkastellaan RFID-perusteisten kulunvalvontajärjestelmien perusominaisuuksia ja niiden toimintaa.

Rakennuksen tietomallien hyödyntämisen edellytykset rakentamisen valmistelu- ja rakennusvaiheessa

Työn tavoitteena oli tutkia, kuinka rakennuksen tietomallia voidaan hyödyntää rakennusliikkeen tuotannonsuunnittelu- ja rakennusvaiheessa sekä mitä sen hyödyntäminen edellyttää rakennuksen tietomallin informaatiosisällöltä. Tavoitteena oli myös tunnistaa tuotannonohjauksen ”pullonkauloja”, joissa kohdin toimintaa voitaisiin tietomallien avulla tehostaa. Työn teoreettisena taustana on aineettoman pääoman merkitys yrityksen kilpailuedun luojana, tietämyksen hallinta ja teknologian hyödyntäminen tietämyksen hallinnassa. Työssä tutkittiin rakennustuotannon johtamista ja tietomallintamisen hyödyntämistä rakentamisessa sekä tietomallien hyödynnettävyyden varmistamista yleisellä tasolla. Työssä tutustuttiin kohdeyritykseen tuotannonohjaukseen ja rakennusvaiheen tietomallien hyödyntämisen nykytilaan. Tuloksina voidaan todeta, että tietomallien tuotannonsuunnittelu- ja rakennusvaiheen tietomallien hyödyntämisen perusedellytys on tietomallien oikeellisuus sekä tietomallien ja perinteisten suunnitteludokumenttien yhdenmukainen tietosisältö. Tämän lisäksi tarvitaan suunnitellut toimintatavat ja toimivat tiedonjakelukanavat sekä kyky hyödyntää tieto- ja viestintäteknologiaa. Tietomallit eivät tämän tutkimuksen perusteella näytä luoneen tarvetta uudenlaisille tuotanto-organisaation roolituksille. Tietomalleilla uskotaan olevan positiivisia vaikutuksia rakennusvaiheen muutostenhallinnassa. Tuotantoorganisaation henkilöillä oli positiivisia odotuksia tietomallien hyödyntämisestä tuotannonohjauksessa. Tietomallien odotetaan tukevan erillisten suunnitelmien muodostamien kokonaisuuksien hahmottamista, rakennusvaiheen osapuolten yhteistyötä ja töiden yhteensovitusta sekä logistiikan suunnittelua ja vaikutusten havainnointia.

Managing Customer Issues through a Support Channel Network

The importance of after-sales service or service in general can be seen and experienced by customers every day with industrial as well as other non-industrial services or products. This dissertation, drawing on theory and experience, focuses on practical engineering implications, specifically the management of customer issues in the after-sales phase in the mobile phone arena. The main objective of this doctoral dissertation is to investigate customer after-sales issue management, specifically regarding mobile phones. The case studies focus on issue resolution time and the issue of corrective actions. This dissertation consists of a main body and four peer-reviewed journal articles and one manuscript currently under review by a peer-reviewed journal. The main body of this dissertation examines the elements of customer satisfaction, loyalty, and retention with respect to corrective actions to address customer issues and issue resolution time through literature and empirical studies. The five independent works are case studies supporting the thesis research questions. This study examines four questions: 1) What are the factors affecting corrective actions for customers? 2) How can customer issue resolution time be controlled? 3) What are the factors affecting processes in the service chain? and 4) How can communication be measured in a service chain? In this work, both quantitative and qualitative analysis methods are used. The main body of the thesis reviews the literature regarding the elements that bridge the five case studies. The case studies of the articles and surveys lean more toward the methodology of critical positivism and then apply the interpretive approach in interpreting the results. The case study articles employ various statistical methods to analyze and to interpret the empirical and survey data. The statistical methods were used to create a model that is useful for significantly optimizing issue resolution time. Moreover, it was found that samples for verifying issues provided by the customer neither improve the perceived quality of corrective actions nor the perceived quality of issue resolution time. The term “service” in this work is limited to the technical services that are provided by product manufacturers and after-sales authorized service vendors. On the basis of this research work, it has been observed that corrective actions and issue resolution time are associated with customer satisfaction and hence, according to induction theory, to customer loyalty and retention. This thesis utilizes knowledge of marketing and customer relationships to contribute to the existing body of knowledge concerning information and communication technology for after-sales service recovery of mobile terminals. The established models in the thesis contribute to the existing knowledge of the after-sales process of dealing with customer issues in the field of mobile phones. The findings suggest that process managers could focus more on communication and training provided to the staff as new technology evolves rapidly. The study also suggest the managers formulate strategies for how customers can be kept informed on a regular basis of the status of issues that have been escalated for corrective action. The findings also lay the foundation for the comprehensive objective to control the entire product development process, starting with conceptualization. This implies that robust design should be applied to the new products so that problems affecting customer service quality are not repeated. The objective will be achieved when the entire service chain from product development to the final user can be modeled and this model can be used to support the organization at all levels.

The Cycle Times of Working Capital: Financial Value Chain Analysis Method

Interest towards working capital management increased among practitioners and researchers because the financial crisis of 2008 caused the deterioration of the general financial situation. The importance of managing working capital effectively increased dramatically during the financial crisis. On one hand, companies highlighted the importance of working capital management as part of short-term financial management to overcome funding difficulties. On the other hand, in academia, it has been highlighted the need to analyze working capital management from a wider perspective namely from the value chain perspective. Previously, academic articles mostly discussed working capital management from a company-centered perspective. The objective of this thesis was to put working capital management in a wider and more academic perspective and present case studies of the value chains of industries as instrumental in theoretical contributions and practical contributions as complementary to theoretical contributions and conclusions. The principal assumption of this thesis is that selffinancing of value chains can be established through effective working capital management. Thus, the thesis introduces the financial value chain analysis method which is employed in the empirical studies. The effectiveness of working capital management of the value chains is studied through the cycle time of working capital. The financial value chain analysis method employed in this study is designed for considering value chain level phenomena. This method provides a holistic picture of the value chain through financial figures. It extends the value chain analysis to the industry level. Working capital management is studied by the cash conversion cycle that measures the length (days) of time a company has funds tied up in working capital, starting from the payment of purchases to the supplier and ending when remittance of sales is received from the customers. The working capital management practices employed in the automotive, pulp and paper and information and communication technology industries have been studied in this research project. Additionally, the Finnish pharmaceutical industry is studied to obtain a deeper understanding of the working capital management of the value chain. The results indicate that the cycle time of working capital is constant in the value chain context over time. The cash conversion cycle of automotive, pulp and paper, and ICT industries are on average 70, 60 and 40 days, respectively. The difference is mainly a consequence of the different cycle time of inventories. The financial crisis of 2008 affected the working capital management of the industries similarly. Both the cycle time of accounts receivable and accounts payable increased between 2008 and 2009. The results suggest that the companies of the automotive, pulp and paper and ICT value chains were not able to self-finance. Results do not indicate the improvement of value chains position in regard to working capital management either. The findings suggest that companies operating in the Finnish pharmaceutical industry are interested in developing their own working capital management, but collaboration with the value chain partners is not considered interesting. Competition no longer occurs between individual companies, but between value chains. Therefore the financial value chain analysis method introduced in this thesis has the potential to support value chains in improving their competitiveness.

Katsaus lisäävän valmistuksen (aka 3D-tulostus) mahdollisuuksiin ja kustannuksiin metallisten tuotteiden valmistuksessa: Case jauhepetitekniikka

Suurelle yleisölle lisäävä valmistustekniikka eli ns. 3D-tulostustekniikka näyttäytyy lehtien otsikoissa ja artikkeleissa esiin pulpahtavana ”muotiaiheena”, mutta sekä muovien 3D-tulostustekniikka että metallienkin vastaava valmistustekniikka on ollut olemassa maailmalla ja Suomessa 80-luvun puolivälistä alkaen. Yhdysvalloissa ja Saksassa tekniikkaa käytetään valmistavassa teollisuudessa toiminnallisten osien tuotannossa. Esimerkiksi lentokoneen suihkumoottorien osia ja lääketieteellisiä välineitä tehdään metallijauheesta lisäävän valmistuksen avulla. Itse asiassa eräs menetelmä metalliesineiden valmistamiseksi lasersäteen avulla keksittiin Suomessa ja sitä myös kehiteltiin täällä, mutta teollisuudenala lähti aikanaan nousuun Saksassa. Lisäävä valmistus on tällä hetkellä maailmanlaajuisesti eräs kiinnostavista tuotantotekniikoista, jonka uskotaan muuttavan monia asioita tuotteiden suunnittelussa, toiminnoissa ja valmistuksessa. Tämä tekniikka ei kiinnosta pelkästään valmistavaa teollisuutta, vaan tietotekniikan, lääketieteen, koruvalmistuksen ja muotoilun osaajat sekä uusien liiketoimintamallien kehittäjät ja logistiikka operaattorit ovat teknologiasta kiinnostuneita. Suomelle 3D-tulostustekniikka on suuri mahdollisuus, sillä maassamme on vahva teollinen tieto- ja viestintätekniikkaosaaminen sekä lisäksi olemme maassamme erikoistuneet varsin vaativien teollisiin laitteiden valmistukseen. Eräät suurimmista mahdollisuuksista tällä tekniikalla ovat toimitusketjuihin liittyvät muutokset. Uutta on, että pienetkin yritykset ja organisaatiot voivat soveltaa tätä tekniikkaa valmistuksessa ja jopa kehitellä täysin uusia tuotteita. On myös arvioitu, että lisäävän valmistuksen merkitys valmistustapoihin ja toimitusketjuihin voi olla suurempi kuin koskaan aikaisemmin minkään teknologisen uudistuksen kohdalla. Lisäävästä valmistuksesta usein puhutaankin kolmantena teollisena vallankumouksena juuri tämän takia. 3D-tulostuksen kustannuksia tarkasteltaessa on tärkeätä huomata että vain sulatetun jauheen määrä ratkaisee, ei käytettävän geometrian monimutkaisuus. Tämä erottaa perinteisen ja lisäävän valmistuksen toisistaan. Perinteisesti kappaleen keventäminen on maksanut ”ylimääräistä”, kun taas lisäävässä valmistuksessa kappaleen keveys on jopa kustannusta alentava tekijä. Valmistettavan kappaleen korkeus on yksi kriittisimpiä kustannuksiin vaikuttavia tekijöitä. Tämän vuoksi useamman kappaleen valmistus yhdellä kertaa parantaa kannattavuutta huomattavasti. Samalla kertaa voi ja itse asiassa kannattaakin valmistaa keskenään erilaisia kappaleita. Perinteiset valmistustavat sen sijaan ovat nykyajan vaatimuksille liian hitaita; ne joustavat huonosti, kun kyseessä on pienet, asiakaslähtöiset erät. Trendi on globaalisti kohden yksilöllisiä asiakaslähtöisiä tuotteita, jolloin myös valmistustekniikoiden on oltava joustavia pysyäkseen näiden vaatimusten perässä. Lisäävä valmistus sopii erityisesti hyvin piensarjatuotantoon. Suuremmissa valmistuserissä kuitenkin perinteiset tekniikat ovat kustannustehokkaampia.

Value of Information Logistics Integration in Digital Business Ecosystem

Digital business ecosystems (DBE) are becoming an increasingly popular concept for modelling and building distributed systems in heterogeneous, decentralized and open environments. Information- and communication technology (ICT) enabled business solutions have created an opportunity for automated business relations and transactions. The deployment of ICT in business-to-business (B2B) integration seeks to improve competitiveness by establishing real-time information and offering better information visibility to business ecosystem actors. The products, components and raw material flows in supply chains are traditionally studied in logistics research. In this study, we expand the research to cover the processes parallel to the service and information flows as information logistics integration. In this thesis, we show how better integration and automation of information flows enhance the speed of processes and, thus, provide cost savings and other benefits for organizations. Investments in DBE are intended to add value through business automation and are key decisions in building up information logistics integration. Business solutions that build on automation are important sources of value in networks that promote and support business relations and transactions. Value is created through improved productivity and effectiveness when new, more efficient collaboration methods are discovered and integrated into DBE. Organizations, business networks and collaborations, even with competitors, form DBE in which information logistics integration has a significant role as a value driver. However, traditional economic and computing theories do not focus on digital business ecosystems as a separate form of organization, and they do not provide conceptual frameworks that can be used to explore digital business ecosystems as value drivers—combined internal management and external coordination mechanisms for information logistics integration are not the current practice of a company’s strategic process. In this thesis, we have developed and tested a framework to explore the digital business ecosystems developed and a coordination model for digital business ecosystem integration; moreover, we have analysed the value of information logistics integration. The research is based on a case study and on mixed methods, in which we use the Delphi method and Internetbased tools for idea generation and development. We conducted many interviews with key experts, which we recoded, transcribed and coded to find success factors. Qualitative analyses were based on a Monte Carlo simulation, which sought cost savings, and Real Option Valuation, which sought an optimal investment program for the ecosystem level. This study provides valuable knowledge regarding information logistics integration by utilizing a suitable business process information model for collaboration. An information model is based on the business process scenarios and on detailed transactions for the mapping and automation of product, service and information flows. The research results illustrate the current cap of understanding information logistics integration in a digital business ecosystem. Based on success factors, we were able to illustrate how specific coordination mechanisms related to network management and orchestration could be designed. We also pointed out the potential of information logistics integration in value creation. With the help of global standardization experts, we utilized the design of the core information model for B2B integration. We built this quantitative analysis by using the Monte Carlo-based simulation model and the Real Option Value model. This research covers relevant new research disciplines, such as information logistics integration and digital business ecosystems, in which the current literature needs to be improved. This research was executed by high-level experts and managers responsible for global business network B2B integration. However, the research was dominated by one industry domain, and therefore a more comprehensive exploration should be undertaken to cover a larger population of business sectors. Based on this research, the new quantitative survey could provide new possibilities to examine information logistics integration in digital business ecosystems. The value activities indicate that further studies should continue, especially with regard to the collaboration issues on integration, focusing on a user-centric approach. We should better understand how real-time information supports customer value creation by imbedding the information into the lifetime value of products and services. The aim of this research was to build competitive advantage through B2B integration to support a real-time economy. For practitioners, this research created several tools and concepts to improve value activities, information logistics integration design and management and orchestration models. Based on the results, the companies were able to better understand the formulation of the digital business ecosystem and the importance of joint efforts in collaboration. However, the challenge of incorporating this new knowledge into strategic processes in a multi-stakeholder environment remains. This challenge has been noted, and new projects have been established in pursuit of a real-time economy.

Viestintäteknologian kehityksen vaikutus organisaation toimintatapoihin ja esimiestyöhön

Tutkimuksen tavoitteena oli selvittää, millä tavoin viestintäteknologian kehitys, globalisaatio sekä organisaatiomuodot ovat suhteessa keskenään sekä miten ne vaikuttavat esimiestyöhön hajautuneessa organisaatiossa. Tutkimuskohteena olivat kymmenen eri asiantuntijaorganisaatiossa esimiesasemassa työskentelevää henkilöä. Tutkimus toteutettiin laadullisin tutkimusmenetelmin. Tutkimusaineisto hankittiin puolistrukturoitujen teemahaastattelujen sekä avoimien haastatteluiden avulla. Tutkimuksen teoreettinen viitekehys rakennettiin hajautuneen organisaation määrittelyn ohella johtamisteorioista sekä organisaation viestinnän teorioista. Tutkimuksen tulosten perusteella hajautuneet organisaatiomuodot yleistyvät uusille toimialoille ja työaika ja –paikka käsitteet muuttuvat. Esimiestyö on sosiaalinen prosessi. Vuorovaikutteinen ja päätösvaltaa jakava esimiestyö on tehokkaan ja joustavan organisaation edellytys. Verkostoituminen on yleistynyt ja on organisaatioiden kannalta järkevämpi tapa saada tarvittava osaaminen käyttöön kuin rekrytoiminen. Tutkimuksen mukaan organisaatiot pyrkivät edesauttamaan verkostoitumista mahdollistamalla työajasta ja –paikasta riippumattoman työn tekemisen. Useimmat organisatioissa käyettävät sovellukset ja järjestelmät toimivat tietoliikenneverkon kautta tai pilvipalveluissa. Työntekijöitä kannustetaan voimakkaasti muodostamaan sekä löytämään omaa ja organisaation osaamista tukevia osaamiskeskuksia. Lisäksi tutkimus vahvistaa aiempien tutkimustulosten mukaisesti, että nykymuotoinen esimiestyö ei toimi työaikaja työpaikkarajoituksista vapautuneessa, hajautuneissa organisaatioissa. Tämän vaikutuksesta myös alaisten rooli muuttuu hajautuneissa organisaatioissa.

Software business expansion through distribution channel : Case M-Files - Denmark

The purpose of this study was to find out how a software company can successfully expand business to the Danish software market through distribution channel. The study was commissioned by a Finnish software company and it was conducted using a qualitative research method by analyzing external and internal business environment, and interviewing Danish ICT organizations and M-Files personnel. Interviews were semi-structured interviews, which were designed to collect comprehensive information on the existing ICT and software market in Denmark. The research used three external and internal analyzing frameworks; PEST analysis (market level), Porter´s Five Force analysis (industry level competition) and SWOT analysis (company level). Distribution channels theory was a base to understand why and what kind of distribution channels the case company uses, and what kind of channels target markets companies’ uses. Channel strategy and design were integrated to the industry level analysis. The empirical findings revealed that Denmark has very business friendly ICT environment. Several organizations have ranked Denmark´s information and communication technology as the best in the world. Denmark’s ICT and software market are relatively small, compared to many other countries in Europe. Danish software market is centralized. Largest software clusters are in the largest cities; Copenhagen, Aarhus, Odense and Aalborg. From these clusters, software companies can most likely find suitable resellers. The following growing trends are clearly seen in the software market: mobile and wireless applications, outsourcing, security solutions, cloud computing, social business solutions and e-business solutions. When expanding software business to the Danish market, it is important to take into account these trends. In Denmark distribution channels varies depending on the product or service. For many, a natural distribution channel is a local partner or internet. In the public sector solutions are purchased through a public procurement process. In the private sector the buying process is more straight forwarded. Danish companies are buying software from reliable suppliers. This means that they usually buy software direct from big software vendors or local partners. Some customers prefer to use professional consulting companies. These consulting companies can strongly influence on the selection of the supplier and products, and in this light, consulting companies can be important partners for software companies. Even though the competition is fierce in ECM and DMS solutions, Danish market offers opportunities for foreign companies. Penetration to the Danish market through reseller channel requires advanced solutions and objective selection criteria for channel partners. Based on the findings, Danish companies are interested in advanced and efficient software solutions. Interest towards M-Files solutions was clearly seen and the company has excellent opportunity to expand business to the Danish market through reseller channel. Since the research explored the Danish ICT and software market, the results of the study may offer valuable information also to the other software companies which are expanding their business to the Danish market.

Empirical studies on software quality construction: Exploring human factors and organizational influences

Software quality has become an important research subject, not only in the Information and Communication Technology spheres, but also in other industries at large where software is applied. Software quality is not a happenstance; it is defined, planned and created into the software product throughout the Software Development Life Cycle. The research objective of this study is to investigate the roles of human and organizational factors that influence software quality construction. The study employs the Straussian grounded theory. The empirical data has been collected from 13 software companies, and the data includes 40 interviews. The results of the study suggest that tools, infrastructure and other resources have a positive impact on software quality, but human factors involved in the software development processes will determine the quality of the products developed. On the other hand, methods of development were found to bring little effect on software quality. The research suggests that software quality is an information-intensive process whereby organizational structures, mode of operation, and information flow within the company variably affect software quality. The results also suggest that software development managers influence the productivity of developers and the quality of the software products. Several challenges of software testing that affect software quality are also brought to light. The findings of this research are expected to benefit the academic community and software practitioners by providing an insight into the issues pertaining to software quality construction undertakings.

Challenges for virtual teams in voluntary organizations

This research concerns virtual teams in the field of volunteer work. The developments in the area of information and communication technology have decreased their costs and made them easily accessible. As a result, it seems natural that also the voluntary organizations have adopted online tools and virtual teams as a part of their work modes. However, virtual teams have not received much research in this context, and one of the goals of this study was to begin closing that gap. The research had two main focus areas: the challenges that the volunteers face in the teams, and the leadership that the teams have. The study used a qualitative approach and semi-structured interviews. The interviews were conducted over Skype and email and included members from six different teams. The case organization was a European-wide student organization that widely utilized virtual teams in its work. The study identified three critical issues for managing the virtual teams. The first challenge was creating common ground for teamwork through electronic communication. Secondly, volunteering created challenges for the teams through variations in the level of commitment of the members, as some left the organization during the term of the team. Lastly, knowledge transfer was a challenge that came from changing the team members regularly each year. As for the second key topic, leadership in the teams was spread among the team members unevenly. The teams had a formal leader, but they exhibited signs of shared leadership, and the team members were able to influence the team through their own level of involvement. Especially the experience that a member had contributed the amount of influence she held. All in all, the challenges that the volunteers faced were similar to those of normal virtual teams. Volunteering brought additional challenges through the varying levels of commitment and the changing of the team members. Additionally, the role of the team leader was not as firm. The results of the study can be applied to other volunteer organizations that utilize virtual teams.

Ohjaus ja oppilaiden urapohdinta. Turkulaisten peruskoulun päättöluokkalaisten ohjauskokemukset urapohdinnan selittäjinä

Tutkimuksessa selvitetään turkulaisten peruskoulun päättöluokkalaisten urapohdintaeroja ja sitä, miten oppilaiden arviot opettajien ja oppilaanohjaajien toteuttamasta ohjauksesta ovat yhteydessä heidän urapohdintaansa. Tutkimuksen kohdejoukkona ovat ensi sijassa yleisopetusta antavien suomenkielisten peruskoulujen yhdeksäsluokkalaiset. Tutkimus on poikkileikkaustutkimus, jossa tarkastellaan oppilaiden kokemuksia ohjauksen saatavuudesta ja hyödyllisyydestä sekä urapohdinnasta peruskoulun päättyessä. Tutkimusaineisto koottiin yhteishaun jälkeen huhti–toukokuussa 2014. Vuoden 2004 perusopetuksen opetussuunnitelman perusteista johdettujen väittämien avulla selitetään urapohdinta-mittarin sisältämien muuttujien vaihtelua. Taustamuuttujina käytetään oppilaiden koti- ja koulutaustaa. Urapohdinta-mittari on johdettu CIP-teoriasta (Cognitive Information Processing) ja muokattu CTI-mittarista (Career Thoughts Inventory). Tutkimusaineisto (N = 887) on koottu Webropol-kyselyn avulla. Oppilaiden urapohdintaa mitattiin neljän summamuuttujien avulla. Mittariston 48 väittämästä muodostettiin urapohdinta-summamuuttuja. Tämän lisäksi urapohdinnan osa-alueita arvioitiin sitoutuminen-, epävarmuus- ja konflikti-summamuuttujan avulla. Sitoutuminen-summamuuttuja mittasi sitä, miten vaikeaksi oppilas koki yhteen ura- ja jatkokoulutusvalintaan sitoutumisen. Epävarmuus-summamuuttuja mittasi päätöksenteon epävarmuutta ja konflikti-summamuuttuja vaikeutta tasapainoilla omien ajatusten ja toisaalta merkittäviksi koettujen läheisten ajatusten välillä. Kaikkien opettajien ohjaustyön näkökulmasta parhaiten hyvää urapohdintatulosta, jatkokoulutukseen sitoutumista ja päätöksentekovarmuutta ennustivat oppilaan hyvät kokemukset yhteistoiminnasta, hänen myönteinen suhtautumisensa koulunkäyntiin ja opintosuoritukset. Myös itseohjautuvuus oli tilastollisesti merkitsevässä yhteydessä urapohdintaan. Itseohjautuvuus-summamuuttuja mittasi sitä, oliko oppilas kokenut, että ohjaukselle asetetut tavoitteet saavutettiin. Opettajien tulisi kiinnittää ohjauksessaan huomiota hiljaisiin ja vähän huomiota vaativiin oppilaisiin ja tukea kaikkien oppilaiden toimintakykyä. Opinto-ohjaajan taas tulisi panostaa oppilaan itsetuntemuksen kehittämiseen ja valmiuteen toimia suunnitelmallisesti. Toisen asteen nivelvaiheohjauksen painopiste tulisi siirtää päättöluokkaa varhaisemmaksi. Tutkimustulos ei tue ajatusta, että tehostettu oppilaanohjaus kohdennettaisiin opintomenestyksen mukaan, koska heikkoja urapohtijoita oli kaikissa keskiarvosanaluokissa. Opinto-ohjaajien tulisi panostaa tieto- ja viestintätekniikan hyödyntämiseen ja tehostaa koko koulun työelämäyhteistyötä.

Specification of a smart meter/actuator description mechanism & development of a mobile application

Home Automation holds the potential of realizing cost savings for end users while reducing the carbon footprint of domestic energy consumption. Yet, adoption is still very low. High cost of vendor-supplied home automation systems is a major prohibiting factor. Open source systems such as FHEM, Domoticz, OpenHAB etc. are a cheaper alternative and can drive the adoption of home automation. Moreover, they have the advantage of not being limited to a single vendor or communication technology which gives end users flexibility in the choice of devices to include in their installation. However, interaction with devices having diverse communication technologies can be inconvenient for users thus limiting the utility they derive from it. For application developers, creating applications which interact with the several technologies in the home automation systems is not a consistent process. Hence, there is the need for a common description mechanism that makes interaction smooth for end users and which enables application developers to make home automation applications in a consistent and uniform way. This thesis proposes such a description mechanism within the context of an open source home automation system – FHEM, together with a system concept for its application. A mobile application was developed as a proof of concept of the proposed description mechanism and the results of the implementation are reflected upon.
