Development of Measurement Systems in Scientific Research: Case Study

In recent years, technological advancements in microelectronics and sensor technologies have revolutionized the field of electrical engineering. New manufacturing techniques have enabled a higher level of integration that has combined sensors and electronics into compact and inexpensive systems. Previously, the challenge in measurements was to understand the operation of the electronics and sensors, but this has now changed. Nowadays, the challenge in measurement instrumentation lies in mastering the whole system, not just the electronics. To address this issue, this doctoral dissertation studies whether it would be beneficial to consider a measurement system as a whole from the physical phenomena to the digital recording device, where each piece of the measurement system affects the system performance, rather than as a system consisting of small independent parts such as a sensor or an amplifier that could be designed separately. The objective of this doctoral dissertation is to describe in depth the development of the measurement system taking into account the challenges caused by the electrical and mechanical requirements and the measurement environment. The work is done as an empirical case study in two example applications that are both intended for scientific studies. The cases are a light sensitive biological sensor used in imaging and a gas electron multiplier detector for particle physics. The study showed that in these two cases there were a number of different parts of the measurement system that interacted with each other. Without considering these interactions, the reliability of the measurement may be compromised, which may lead to wrong conclusions about the measurement. For this reason it is beneficial to conceptualize the measurement system as a whole from the physical phenomena to the digital recording device where each piece of the measurement system affects the system performance. The results work as examples of how a measurement system can be successfully constructed to support a study of sensors and electronics.

R&D Performance Analysis: Case Studies on the Challenges and Promotion of the Evaluation and Measurement of R&D

Due to the intense international competition, demanding, and sophisticated customers, and diverse transforming technological change, organizations need to renew their products and services by allocating resources on research and development (R&D). Managing R&D is complex, but vital for many organizations to survive in the dynamic, turbulent environment. Thus, the increased interest among decision-makers towards finding the right performance measures for R&D is understandable. The measures or evaluation methods of R&D performance can be utilized for multiple purposes; for strategic control, for justifying the existence of R&D, for providing information and improving activities, as well as for the purposes of motivating and benchmarking. The earlier research in the field of R&D performance analysis has generally focused on either the activities and considerable factors and dimensions - e.g. strategic perspectives, purposes of measurement, levels of analysis, types of R&D or phases of R&D process - prior to the selection of R&Dperformance measures, or on proposed principles or actual implementation of theselection or design processes of R&D performance measures or measurement systems. This study aims at integrating the consideration of essential factors anddimensions of R&D performance analysis to developed selection processes of R&D measures, which have been applied in real-world organizations. The earlier models for corporate performance measurement that can be found in the literature, are to some extent adaptable also to the development of measurement systemsand selecting the measures in R&D activities. However, it is necessary to emphasize the special aspects related to the measurement of R&D performance in a way that make the development of new approaches for especially R&D performance measure selection necessary: First, the special characteristics of R&D - such as the long time lag between the inputs and outcomes, as well as the overall complexity and difficult coordination of activities - influence the R&D performance analysis problems, such as the need for more systematic, objective, balanced and multi-dimensional approaches for R&D measure selection, as well as the incompatibility of R&D measurement systems to other corporate measurement systems and vice versa. Secondly, the above-mentioned characteristics and challenges bring forth the significance of the influencing factors and dimensions that need to be recognized in order to derive the selection criteria for measures and choose the right R&D metrics, which is the most crucial step in the measurement system development process. The main purpose of this study is to support the management and control of the research and development activities of organizations by increasing the understanding of R&D performance analysis, clarifying the main factors related to the selection of R&D measures and by providing novel types of approaches and methods for systematizing the whole strategy- and business-based selection and development process of R&D indicators.The final aim of the research is to support the management in their decision making of R&D with suitable, systematically chosen measures or evaluation methods of R&D performance. Thus, the emphasis in most sub-areas of the present research has been on the promotion of the selection and development process of R&D indicators with the help of the different tools and decision support systems, i.e. the research has normative features through providing guidelines by novel types of approaches. The gathering of data and conducting case studies in metal and electronic industry companies, in the information and communications technology (ICT) sector, and in non-profit organizations helped us to formulate a comprehensive picture of the main challenges of R&D performance analysis in different organizations, which is essential, as recognition of the most importantproblem areas is a very crucial element in the constructive research approach utilized in this study. Multiple practical benefits regarding the defined problemareas could be found in the various constructed approaches presented in this dissertation: 1) the selection of R&D measures became more systematic when compared to the empirical analysis, as it was common that there were no systematic approaches utilized in the studied organizations earlier; 2) the evaluation methods or measures of R&D chosen with the help of the developed approaches can be more directly utilized in the decision-making, because of the thorough consideration of the purpose of measurement, as well as other dimensions of measurement; 3) more balance to the set of R&D measures was desired and gained throughthe holistic approaches to the selection processes; and 4) more objectivity wasgained through organizing the selection processes, as the earlier systems were considered subjective in many organizations. Scientifically, this dissertation aims to make a contribution to the present body of knowledge of R&D performance analysis by facilitating dealing with the versatility and challenges of R&D performance analysis, as well as the factors and dimensions influencing the selection of R&D performance measures, and by integrating these aspects to the developed novel types of approaches, methods and tools in the selection processes of R&D measures, applied in real-world organizations. In the whole research, facilitation of dealing with the versatility and challenges in R&D performance analysis, as well as the factors and dimensions influencing the R&D performance measure selection are strongly integrated with the constructed approaches. Thus, the research meets the above-mentioned purposes and objectives of the dissertation from the scientific as well as from the practical point of view.

Performance Measurement as Part of Management

To achieve success in a constantly changing environment and with ever-increasing competition, companies must develop their operations continuously. To do this, they must have a clear vision of what they want to be in the future. This vision can be attained through careful planning and strategising. One method of transforming a strategy and vision into an everyday tool used by employees is the use of a balanced performance measurement system. The importance of performance measurement in the implementation of companies' visions and strategies has grown substantially in the last ten years. Measures are derived from the company's critical success factors and from many different perspectives. There are three time dimensions: past, present and future. Many such performance measurement systems have been created since the 1990s. This is a case study whose main objective is to provide a recommendation for how the case company could make use of performance measurement to support strategic management. To answer this question, the study uses literature-based research and empirical research at the case company's premises. The theoretical part of the study consists of two sections: introducing the Balanced Scorecard and discussing how it supports strategic management and change management. The empirical part of this study determines the company's present performance measurement situation through interviews in the company. The study resulted in a recommendation to the company to start developing the Balanced Scorecard system. By setting up this kind process, the company would be able to change its focus more towards the future, beginning to implement a more process-based organisation and getting its employees to work together towards common goals.

Multifactor Performance Study on Complex Systems for the Benefit of Management

The primary objective is to identify the critical factors that have a natural impact on the performance measurement system. It is important to make correct decisions related to measurement systems, which are based on the complex business environment. The performance measurement system is combined with a very complex non-linear factor. The Six Sigma methodology is seen as one potential approach at every organisational level. It will be linked to the performance and financial measurement as well as to the analytical thinking on which the viewpoint of management depends. The complex systems are connected to the customer relationship study. As the primary throughput can be seen in a new well-defined performance measurement structure that will also be facilitated as will an analytical multifactor system. These critical factors should also be seen as a business innovation opportunity at the same time. This master's thesis has been divided into two different theoretical parts. The empirical part consists of both action-oriented and constructive research approaches with an empirical case study. The secondary objective is to seek a competitive advantage factor with a new analytical tool and the Six Sigma thinking. Process and product capabilities will be linked to the contribution of complex system. These critical barriers will be identified by the performance measuring system. The secondary throughput can be recognised as the product and the process cost efficiencies which throughputs are achieved with an advantage of management. The performance measurement potential is related to the different productivity analysis. Productivity can be seen as one essential part of the competitive advantage factor.

Managing through measurement : A framework for successful operative level performance measurement

The research around performance measurement and management has focused mainly on the design, implementation and use of performance measurement systems. However, there is little evidence about the actual impacts of performance measurement on the different levels of business and operations of organisations, as well as the underlying factors that lead to a positive impact of performance measurement. The study thus focuses on this research gap, which can be considered both important and challenging to cover. The first objective of the study was to examine the impacts of performance measurement on different aspects of management, leadership and the quality of working life, after which the factors that facilitate and improve performance and performance measurement at the operative level of an organisation were examined. The second objective was to study how these factors operate in practice. The third objective focused on the construction of a framework for successful operative level performance measurement and the utilisation of the factors in the organisations. The research objectives have been studied through six research papers utilising empirical data from three separate studies, including two sets of interview data and one of quantitative data. The study applies mainly the hermeneutical research approach. As a contribution of the study, a framework for successful operative level performance measurement was formed by matching the findings of the current study and performance measurement theory. The study extents the prior research regarding the impacts of performance measurement and the factors that have a positive effect on operative level performance and performance measurement. The results indicate that under suitable circumstances, performance measurement has positive impacts on different aspects of management, leadership, and the quality of working life. The results reveal that for example the perception of the employees and the management of the impacts of performance measurement on leadership style differ considerably. Furthermore, the fragmented literature has been reorganised into six factors that facilitate and improve the performance of the operations and employees, and the use of performance measurement at the operative level of an organisation. Regarding the managerial implications of the study, managers who operate around performance measurement can utilise the framework for example by putting the different phases of the framework into practice.

Sales performance measurement and steering in a multinational company

The objective of the study is to find out how sales performance should be measured and how should sales be steered in a multinational company. The beginning of the study concentrates on the literature regarding sales, performance measurement, sales performance measurement, and sales steering. The empirical part of the study is a case study, in which the information was acquired from interviews with the key personnel of the company. The results of the interviews and the revealed problems were analyzed, and comparison for possible solutions was performed. When measuring sales performance, it is important to discover the specific needs and objectives for such a system. Specific needs should be highlighted in the design of the system. The system should be versatile and the structure of the system should be in line with the organizational structure. The role of the sales performance measurement system was seen to be important in helping sales steering. However, the importance of personal management and especially conversations were seen as really critical issue in the steering. Sales performance measurement could be based on the following perspectives: financial, market, customer, people, and future. That way the sales department could react to the environmental changes more rapidly.

Content marketing performance measurement system in the context of customer acquisition

This thesis examines how content marketing is used in B2B customer acquisition and how content marketing performance measurement system is built and utilized in this context. Literature related to performance measurement, branding and buyer behavior is examined in the theoretical part in order to identify the elements influence on content marketing performance measurement design and usage. Qualitative case study is chosen in order to gain deep understanding of the phenomenon studied. The case company is a Finnish software vendor, which operates in B2B markets and has practiced content marketing for approximately two years. The in-depth interviews were conducted with three employees from marketing department. According to findings content marketing performance measurement system’s infrastructure is based on target market’s decision making processes, company’s own customer acquisition process, marketing automation tool and analytics solutions. The main roles of content marketing performance measurement system are measuring performance, strategy management and learning and improvement. Content marketing objectives in the context of customer acquisition are enhancing brand awareness, influencing brand attitude and lead generation.

Performance measurement model for projects from a strategic management perspective

This research studied the project performance measurement from the perspective of strategic management. The objective was to find a generic model for project performance measurement that emphasizes strategy and decision making. Research followed the guidelines of a constructive research methodology. As a result, the study suggests a model that measures projects with multiple meters during and after projects. Measurement after the project is suggested to be linked to the strategic performance measures of a company. The measurement should be conducted with centralized project portfolio management e.g. using the project management office in the organization. Metrics, after the project, measure the project’s actual benefit realization. During the project, the metrics are universal and they measure the accomplished objectives relation to costs, schedule and internal resource usage. Outcomes of these measures should be forecasted by using qualitative or stochastic methods. Solid theoretical background for the model was found from the literature that covers the subjects of performance measurement, projects and uncertainty. The study states that the model can be implemented in companies. This statement is supported by empirical evidence from a single case study. The gathering of empiric evidence about the actual usefulness of the model in companies is left to be done by the evaluative research in the future.

Relay card for capacitance measurements

In this bachelor's thesis a relay card for capacitance measurements was designed, built and tested. The study was made for the research and development laboratory of VTI Technologies, which manufactures capacitive silicon micro electro mechanical accelerometers and pressure sensors. As the size of the sensors is decreasing the capacitance value of the sensors also decreases. The decreased capacitance causes a need for new and more accurate measurement systems. The technology used in the instrument measuring the capacitance dictates a framework how the relay card should be designed, thus the operating principle of the instrument must be known. To achieve accurate results the measurement instrument and its functions needed to be used correctly. The relay card was designed using printed circuit board design methods that minimize interference coupling to the measurement. The relay card that was designed in this study is modular. It consists of a separate CPU card, which was used to control the add-on cards connected to it. The CPU card was controlled from a computer through a serial bus. Two add-on cards for the CPU card were designed in this study. The first one was the measurement card, which could be used to measure 32 capacitive sensors. The second add-on card was the MUX card, which could be used to switch between two measurement cards. The capacitance measurements carried out through the MUX card and the measurement cards were characterized with a series of test measurements. The test measurement data was then analysed. The relay card design was confirmed to work and offer accurate measurement results up to a measurement frequency of 10 MHz. The length of the measurement cables limited the measurement frequency.

Suorituskykymittariston kehittäminen taloushallinnon palvelukeskukseen

Tämän tutkimuksen tavoitteena oli kehittää kohdeorganisaationa olevalle taloushallinnon palvelukeskukselle suorituskykymittaristo suorituskyvyn seurantaa ja toiminnan ohjaamista varten. Lähtökohtana oli, että mittaristo tulee johtaa strategisten tavoitteiden ja kriittisten menestystekijöiden kautta palvelukeskuksen visiosta, missiosta ja arvoista ja sen tulee kattaa koko palvelukeskuksen toiminta. Vastauksia etsittiin kysymyksiin: Mitkä ovat kohdeorganisaation visio, missio, arvot, strategiset tavoitteet ja kriittiset menestystekijät? Mitkä ovat kohdeorganisaation seurattavat ja toimintaa ohjaavat mittarit eri tasoilla (palvelukeskus- ja tiimitaso)? Mistä, millaisia raportteja käyttäen, kenen toimestaja kuinka usein kerätään seurantadataa valittujen mittareiden osalta? Tutkimus on pääosin luonteeltaan laadullinen toimintatutkimus, mutta sisältää myös konstruktiivisen tutkimusotteen piirteitä. Työn alkuosa, missä käsitellään strategiaan, asiantuntijatyöhön, palvelukeskusmalliin ja mittaristoihin liittyvää teoriaa, on luonteeltaan käsiteanalyyttinen. Tutkimuksen tuloksena täsmennettiin palvelukeskuksen visio, missio, arvot, strategiset tavoitteet, kriittiset menestystekijät sekä mittaristo ohjaustietoineen.

Ympäristötietämyksen hallintasovelluksen kehittäminen

Uudistunut ympäristölainsäädäntö vaatii energiantuotantolaitoksilta yhä enemmän järjestelmällistä ympäristötiedon hallintaa. LCP- ja jätteenpolttoasetuksen velvoitteet ovat asettaneet uusia vaatimuksia päästöjen valvontaan ja siihen käytettävien mittausjärjestelmien laadunvarmennukseen sekä päästötietojen raportointiin. Uudistukset ovat lisänneet huomattavasti laitoksilla ympäristötiedon käsittelyyn kuluvaa aikaa. Laitosten toimintaehdot määritellään ympäristöviranomaisen myöntämässä ympäristöluvassa, joka on tärkein yksittäinen laitoksen toimintaa ohjaava tekijä. Tämän lisäksi monet toimijat haluavat parantaa ympäristöasioiden tasoaan vapaaehtoisilla ympäristöjärjestelmillä. Tässä diplomityössä kuvataan energiantuotantolaitosten ympäristöasioiden tallentamiseen ja hallintaan kehitetty selainpohjainen Metso Automationin DNAecoDiary'sovellus. Työ on rajattu koskemaan Suomessa toimivia LCP- ja/tai jätteenpolttoasetuksen alaisia laitoksia. Sovelluksen avulla voidaan varmistaa energiantuotantolaitosten poikkeamien, häiriöilmoitusten, päästömittalaitteisiin liittyvien tapahtumien ja muun ympäristöasioiden valvontaan liittyvän informaation tehokas hallinta. Sovellukseen tallennetaan ympäristötapahtumiin liittyvät perustiedot sekä etenkin käyttäjien tapahtumiin liittyvä kokemustietämys. Valvontakirjaukseen voidaan liittää tapahtuman perustietojen lisäksi myös tiedostoja ja kuvia. Sovellusta ja sillä kerättyä tietoa voidaan hyödyntää laitoksella käsilläolevien ongelmien ratkaisuun, ympäristötapahtumien todentamiseen sekä ympäristöraporttien laadintaan. Kehitystyön tueksi järjestettiin asiakastarvekartoitus, jonka perusteella ideoitiin sovelluksen ominaisuuksia. Tässä työssä on esitetty ympäristötiedon hallinan perusteet, selvitetty DNAecoDiaryn toimintaperiaatteet ja annettu esimerkkejä sen hyödyntämisestä. Sovelluksen lopullinen sisältö määritellään kunkin asiakkaan ympäristöluvan ja oma-valvonnan tarpeiden mukaisesti. Sovellus toimii itsenäisesti tai osana laajempaa Metso Automationin päästöjenhallinta- ja raportointisovelluskokonaisuutta.

Ydinvoimalaitoksen tuotannon ylläpitoprosessin suorituskyvyn mittaaminen

Kilpailun kiristyminen on pakottanut ydinvoimalaitoksia parantamaan tehokkuuttaan etsimällä uusia toimintatapoja. Heräte työn teettämiseen syntyi tutkimuksen case-kohteen Loviisan voimalaitoksen kiinnostuksesta Balanced Scorecard (BSC) -johtamisjärjestelmää,sen käyttöönoton mahdollisia vaikutuksia sekä BSC:n ja prosessiajattelun yhdistämistä kohtaan. Tutkimuksen tavoitteena on rakentaa Loviisan voima-laitoksen tuotannon ylläpitoprosessille BSC-mittaristo. Tämä edellyttää selvitystä siitä, mitä erityispiirteitä ydinvoimalaitoksiin liittyy strategisen suorituskyvyn mittaamisen kohteena. Lisäksi tavoitteena on selvittää, mikä tulisi prosessikohtaisten tuloskorttien rooli olla Loviisan voimalaitoksen BSC-järjestelmässä. Tavoitteenaon myös muodostaa suositus toimintamallista, jolla BSC voitaisiin ottaa käyttöön Loviisan voimalaitoksella, sekä selvittää, mitä vaikutuksia käyttöönotolla voiolla. Ydinvoimalaitoksen erityispiirteitä ovat muutokset toimintaympäristössä, viranomais-valvonta, toiminnan pitkäjänteisyys, laaja osaamis- ja tietotarve sekä turvallisuuden ja tiettyjen sidosryhmäsuhteiden merkityksen korostuminen. Johtuen erityispiirteistä Kaplanin ja Nortonin alkuperäistä asiakasnäkökulmaa muutetaan kattamaan sidosryhmät laajemmin. Tuotannon ylläpitoprosessin tuloskortissa vähiten painottuva näkö-kulma on henkilöstön ja uudistumisen näkökulma. Osa laitostason kriittisistä menestystekijöistä todetaan prosessin kannalta epäolennaisiksi. Prosessikohtaiset tuloskortit osoittautuvat vaikeasti hyödynnettäviksi linjaorganisaation ohjaamisessa. Strategiakartta todetaan hyväksi työvälineeksi BSC:nlaadinnassa. Toivasen projektimalli arvioidaan sopivaksi välineeksi mahdolliseen BSC:n käyttöönottoon Loviisan voimalaitoksella. Henkilöstön rooli ja erityispiirteiden vaikutukset tulee kuitenkin tarkistaa ennen mallin käyttöä. BSC-järjestelmän käyttöönoton arvioidaan selkeyttävän voimalaitoksen mittaristokokonaisuutta sekä parantavan syy-seuraussuhteiden hahmottamista ja alempien tasojen tavoitteiden kytkentää laitostason tavoitteisiin.

Uuteaineiden on-line-mittaus koivusulfaattisellutehtaalla

Tämän työn tarkoituksena oli tutkia pihkanhallintaa sulfaattisellutehtaalla ja uuteaineiden analysointimenetelmiä massasta ja suodoksesta. Tavoitteena oli kehittää uuteaineiden on-line mittausmenetelmä sulfaattisellutehtaalle. Kirjallisuusosassa esitettiin sulfaattisellun valmistusprosessi ja uuteaineiden käyttäytyminen prosessissa. Lisäksi työssä käsiteltiin tärkeimpiä pihkanhallintamenetelmiä ja uuteaineiden analysointia. Kokeellisessa osassa määritettiin uuteainepitoisuudet 29:stä massa- ja pesusuodosnäytteestä. Lisäksi suodosnäytteiden sameus ja kemiallinen hapenkulutus määritettiin laboratoriossa. On-line mittaukset tehtiin DD-pesurin paluusuodoksesta, josta mitattiin johtokyky, lämpötila, taitekerroin ja pH. Sameutta yritettiin mitata on-line nefelometrillä, mutta käytössä ollut laite ei soveltunut tumman suodoksen mittaamiseen. Työssä saatujen tulosten perusteella voidaan todeta, että pesusuodoksen ominaisuuksia mittaamalla ei voida arvioida massan uutepitoisuutta luotettavasti. Suodoksen ja massan uutepitoisuuksien välinen selitysaste oli 54%. Saippuoitumattomien uuteaineiden pitoisuuden ollessa erityisen suuri, suodoksen uutepitoisuus ei korreloi massassa olevan uutteen määrän kanssa. Täten kyseinen mittausmenetelmä ei ole sopiva, sillä se ei toimi silloin, kun olisi tärkeintä tietää oikea uuteainepitoisuus pihkanhallintakemikaalien annosten määrittämiseksi. Suodoksen sameus riippui sen uutepitoisuudesta 80% selitysasteella. Sameusmittaus on nopea ja suhteellisen luotettava menetelmä suodosten uutepitoisuuksien arviointiin, mutta se vaatii mittalaitteen joka käyttää usean ilmaisimen tekniikkaa. On-line-mittauksissa laitteisto tulisi varustaa automaattisella pesulaitteella, sillä mittarin linssit likaantuvat helposti prosessivirrassa.
