Measuring Cost of Poor Quality in Industrial Electronics

Quality is not only free but it can be a profit maker. Every dollar that is not spent on doing things wrong becomes a dollar right on the bottom line. The main objective of this thesis is to give an answer on how cost of poor quality can be measured theoretically correctly. Different calculation methods for cost of poor quality are presented and discussed in order to give comprehensive picture about measurement process. The second objective is to utilize the knowledge from the literature review and to apply it when creating a method for measuring cost of poor quality in supplier performance rating. Literature review indicates that P-A-F model together with ABC methodology provides a mean for quality cost calculations. These models give an answer what should be measured and how this measurement should be carried out. However, when product or service quality costs are incurred when quality character derivates from target value, then QLF seems to be most appropriate methodology for quality cost calculation. These methodologies were applied when creating a quality cost calculation method for supplier performance ratings.

Tuulivoimateollisuuden tarkastelu patenttianalyysiä hyödyntäen

Työssä luodaan katsaus tuulivoiman käyttöön historiassa sekä tuulivoiman hyödyntämiseen sähköntuotantoon nykyaikaisessa yhteiskunnassa. Lisäksi esitellään modernin kolmilapaisen tuuliturbiinin tekniikkaa. Työssä tarkastellaan kolmen suuren tuulivoimaloita valmistavien yrityksien patentointiaktiivisutta aikavälillä 2000–2010 ja patenttien lukumäärässä, maantieteellisessä vaihtelussa, tyypissä ja luokissa esiintyviä trendejä. Näiden pohjalta luodaan kokonaiskuva tuulivoiman teollisuuden kehityksestä 2000-luvun alussa ja odotetuista tulevaisuuden näkymistä. Vuosituhannen vaihteen jälkeen patentointiaktiivisuus on kasvanut tuulivoimateknologiayrityksillä. Etenkin vuonna 2007 havaitaan piikki patenttien lukumäärässä. Patentointitoiminta on keskittynyt Eurooppaan, Pohjois-Amerikkaan sekä Kiinaan. Tuulivoimateknologian voidaan olettaa kehittyvän sekä koossa että kustannustehokkuudessa.

Generic Life Cycle Cost Model and Cost-effective Solutions

Life cycle costing (LCC) practices are spreading from military and construction sectors to wider area of industries. Suppliers as well as customers are demanding comprehensive cost knowledge that includes all relevant cost elements through the life cycle of products. The problem of total cost visibility is being acknowledged and the performance of suppliers is evaluated not just by low acquisition costs of their products, but by total value provided through the life time of their offerings. The main purpose of this thesis is to provide better understanding of product cost structure to the case company. Moreover, comprehensive theoretical body serves as a guideline or methodology for further LCC process. Research includes the constructive analysis of LCC related concepts and features as well as overview of life cycle support services in manufacturing industry. The case study aims to review the existing LCC practices within the case company and provide suggestions for improvements. It includes identification of most relevant life cycle cost elements, development of cost breakdown structure and generic cost model for data collection. Moreover, certain cost-effective suggestions are provided as well. This research should support decision making processes, assessment of economic viability of products, financial planning, sales and other processes within the case company.

Development of Cost Estimation with Feedback Information in EPCM Business

Target company of this study is a large machinery company, which is, inter alia, engaged in energy and pulp engineering, procurement and construction management (EPCM) supply business. The main objective of this study was to develop cost estimation of the target company by providing more accurate, reliable and up-to-date information through enterprise resource planning (ERP) system. Another objective was to find cost-effective methods to collect total cost of ownership information to support more informed supplier selection decision making. This study is primarily action-oriented, but also constructive, and it can be divided in two sections: theoretical literature review and empirical study on the abovementioned part of the target company’s business. Development of information collection is, in addition to literature review, based on nearly 30 qualitative interviews of employees at various organizational units, functions and levels at the target company. At the core of development was to make initial data more accurate, reliable and available, a necessary prerequisite for informed use of the information. Certain development suggestions and paths were presented in order to regain confidence in ERP system as information source by reorganizing work breakdown structure and by complementing mere cost information with quantitative, technical and scope information. Several methods to use the information ever more effectively were also discussed. While implementation of the development suggestions outreached the scope of this study, it was forwarded in test environment and interest groups.

SOCIAL MEDIA IN INTERNATIONAL BRAND COMMUNICATION OF SMES - A multiple case study of small Finnish design-intensive companies

Social media is a rather new phenomenon which has revolutionised the world of online communication. However, academic research on how companies can benefit from social media is lacking. The research objective of this thesis was to examine the use of social media in international brand communication of small Finnish design-intensive companies. Therefore, this research contributes also to the research gap in SME branding. The focus was on communication targeted at consumers. The research was carried out as a mixed methods research employing the questionnaire and multiple case study methods. The questionnaire was used to gather preliminary information on Finnish design-intensive companies and to provide an eligible list of companies for deeper examination. Then, four case companies were studied in more depth. The empirical evidence of the case companies was mainly gathered through theme interviews. The results of the questionnaire shed light on the internationalisation of small Finnish designintensive companies. On average, the companies had internationalised rather quickly after they had been founded. However, the share of exports was rather low in most of the companies. The results revealed also that social media was already used widely in the exporting companies and the use can be expected to grow in future. The findings of the multiple case study suggest that branding activities in small Finnish designintensive companies are constrained by limited resources and skills. In addition, the branding activities are strongly guided by the vision and values of the entrepreneur(s) rather than extensive marketing research. The brand structure was simple in all case companies and they aimed at having a standardised brand image across markets. However, all case companies had faced a need for some adaptation of their international brand communication. Internationally important brand communication channels were international fairs, the internet, word-of-mouth and social media. Social media offered a cost-effective brand communication channel for the case companies. It was used for various purposes, such as creating brand awareness and affecting how the brand is perceived. The entrepreneurs found the use of social media to be rather easy and the case companies had not faced any major challenges. However, the companies had recognised that communication in social media requires consistency and planning. The planning was rather informal and stayed on a general level. Overall, the utilisation of social media in the case companies was limited by a lack of resources. It seemed to affect especially the follow-up of brand communication in social media which stayed rather superficial.

Sähkögeneraattoriosien hitsauksen tuottavuuden kehittäminen

Hitsauksen tuottavuuteen vaikuttavat hitsausmäärä, käytetyt prosessit ja laatu. Työn teoriaosuudessa tutustutaan hitsauksen tuottavuuteen sekä suunnittelullisesta että valmistuksellisesta näkökulmasta. Hitsauksen laadulliset asiat, kuten laatustandardit ja vaatimukset käydään läpi keskittyen standardin SFS-EN ISO 3834 kattaviin laatuvaatimuksiin. Rikkomaton ja rikkova aineenkoetus ja yleisimmät hitsausvirheet esitetään yleisellä tasolla. Hitsausprosesseista esitetään MIG/MAG- ja MAG-täytelankahitsauksen sekä pulssihitsauksen perusteet. Tässä diplomityössä tutkitaan pulssihitsauksen soveltuvuutta sähkögeneraattorin staattoripaketin eripariliitoksen hitsaukseen ja kykyä parantaa sekä tuottavuutta että laatua. Tutkimus perustuu koehitsauksiin ja niiden perusteella tehtyihin johtopäätöksiin. Lisäksi pohditaan sisätuulettimien hitsauksen kehittämistä ja annetaan kehitysehdotus valmistusprosessista. Koehitsauksien perusteella pulssihitsaus on hyvä prosessiparannus staattoripakettien hitsaukseen. Kohdistettu valokaari ja alhaisempi lämmöntuonti verrattuna perinteiseen MAG-hitsaukseen sekä hitsauksen yksinkertaisuus tuovat etuja eripariliitoksen hitsauksen laatuun. Kustannuslaskelmien myötä hitsausprosessin muutoksen odotetaan tuovan kustannussäästöjä. Hitsauslaadun parantuessa ja jälkityöstön määrän vähentyessä hitsausprosessin muutos on kannattava.

Cost-effectiveness analysis in South Karelia Central Hospital

The target organization of this study, otherwise South-Karelia Social and Health Care District (Eksote) provides health, senior, family and social welfare services. South Karelia Central Hospital provides special health care and offers health services from all of the most important medical specialties. Eksote has in use 15D instrument to measure the health-related quality of life (HRQoL) of their patients before and after their interventions for observing the health effects of the medical care. Furthermore, 15D allows measuring the effectiveness and cost-effectiveness of health care when comparing these before and after results of the 15D measurements and adding the costs of the interventions into this research. The main purposes of this study were to analyze the effectiveness and cost-effectiveness of medical care in South Karelia Central Hospital by using the gathered 15D data to calculate effectiveness and cost-effectiveness ratios and to analyze the reliability and availability of the data. Study has been conducted using literature review and quantitative research methods. The results indicate that from the patients within the eight units selected to this study the 15D change information was available from the 52 %, the 15D change and the cost information from 38 % and the information of quality-adjusted life years (QALYs) produced and the cost information from 35 %. The effectiveness and cost-effectiveness of medical care were greatest at the units of Pain Outpatient Clinic and Rheumatic Diseases Outpatient Clinic. The most effective medical care is given in the unit where the average price of one produced QALY is the highest (Orthopedics). However, the calculated standard deviations pointed out that there are great variances in the effectiveness and cost-effectiveness within the units also.

Drivers and barriers of mobile travel and tourism service adoption : a study of individual perceptions and business model development in a travel and tourism context

The Travel and Tourism field is undergoing changes due to the rapid development of information technology and digital services. Online travel has profoundly changed the way travel and tourism organizations interact with their customers. Mobile technology such as mobile services for pocket devices (e.g. mobile phones) has the potential to take this development even further. Nevertheless, many issues have been highlighted since the early days of mobile services development (e.g. the lack of relevance, ease of use of many services). However, the wide adoption of smartphones and the mobile Internet in many countries as well as the formation of so-called ecosystems between vendors of mobile technology indicate that many of these issues have been overcome. Also when looking at the numbers of downloaded applications related to travel in application stores like Google Play, it seems obvious that mobile travel and tourism services are adopted and used by many individuals. However, as business is expected to start booming in the mobile era, many issues have a tendency to be overlooked. Travelers are generally on the go and thus services that work effectively in mobile settings (e.g. during a trip) are essential. Hence, the individuals’ perceived drivers and barriers to use mobile travel and tourism services in on-site or during trip settings seem particularly valuable to understand; thus this is one primary aim of the thesis. We are, however, also interested in understanding different types of mobile travel service users. Individuals may indeed be very different in their propensity to adopt and use technology based innovations (services). Research is also switching more from investigating issues of mobile service development to understanding individuals’ usage patterns of mobile services. But designing new mobile services may be a complex matter from a service provider perspective. Hence, our secondary aim is to provide insights into drivers and barriers of mobile travel and tourism service development from a holistic business model perspective. To accomplish the research objectives seven different studies have been conducted over a time period from 2002 – 2013. The studies are founded on and contribute to theories within diffusion of innovations, technology acceptance, value creation, user experience and business model development. Several different research methods are utilized: surveys, field and laboratory experiments and action research. The findings suggest that a successful mobile travel and tourism service is a service which supports one or several mobile motives (needs) of individuals such as spontaneous needs, time-critical arrangements, efficiency ambitions, mobility related needs (location features) and entertainment needs. The service could be customized to support travelers’ style of traveling (e.g. organized travel or independent travel) and should be easy to use, especially easy to take into use (access, install and learn) during a trip, without causing security concerns and/or financial risks for the user. In fact, the findings suggest that the most prominent barrier to the use of mobile travel and tourism services during a trip is an individual’s perceived financial cost (entry costs and usage costs). It should, however, be noted that regulations are put in place in the EU regarding data roaming prices between European countries and national telecom operators are starting to see ‘international data subscriptions’ as a sales advantage (e.g. Finnish Sonera provides a data subscription in the Baltic and Nordic region at the same price as in Finland), which will enhance the adoption of mobile travel and tourism services also in international contexts. In order to speed up the adoption rate travel service providers could consider e.g. more local initiatives of free Wi-Fi networks, development of services that can be used, at least to some extent, in an offline mode (do not require costly network access during a trip) and cooperation with telecom operators (e.g. lower usage costs for travelers who use specific mobile services or travel with specific vendors). Furthermore, based on a developed framework for user experience of mobile trip arrangements, the results show that a well-designed mobile site and/or native application, which preferably supports integration with other mobile services, is a must for true mobile presence. In fact, travel service providers who want to build a relationship with their customers need to consider a downloadable native application, but in order to be found through the mobile channel and make contact with potential new customers, a mobile website should be available. Moreover, we have made a first attempt with cluster analysis to identify user categories of mobile services in a travel and tourism context. The following four categories were identified: info-seekers, checkers, bookers and all-rounders. For example “all-rounders”, represented primarily by individuals who use their pocket device for almost any of the investigated mobile travel services, constituted primarily of 23 to 50 year old males with high travel frequency and great online experience. The results also indicate that travel service providers will increasingly become multi-channel providers. To manage multiple online channels, closely integrated and hybrid online platforms for different devices, supporting all steps in a traveler process should be considered. It could be useful for travel service providers to focus more on developing browser-based mobile services (HTML5-solutions) than native applications that work only with specific operating systems and for specific devices. Based on an action research study and utilizing a holistic business model framework called STOF we found that HTML5 as an emerging platform, at least for now, has some limitations regarding the development of the user experience and monetizing the application. In fact, a native application store (e.g. Google Play) may be a key mediator in the adoption of mobile travel and tourism services both from a traveler and a service provider perspective. Moreover, it must be remembered that many device and mobile operating system developers want service providers to specifically create services for their platforms and see native applications as a strategic advantage to sell more devices of a certain kind. The mobile telecom industry has moved into a battle of ecosystems where device makers, developers of operating systems and service developers are to some extent forced to choose their development platforms.

Uuteen organisaatioon rakennettavan kustannuslaskentajärjestelmän sertifioiminen valtionhallinnossa: Case Maanmittauslaitos

Työn lähtökohtana oli tieto siitä, että Valtiontalouden tarkastusvirasto (VTV) on lähtenyt tarjoamaan kustannuslaskentajärjestelmien sertifiointeja valtion virastoille ja laitoksille. Ensimmäisenä tavoitteena oli selvittää, mitä kustannuslaskentajärjestelmien sertifioiminen valtionhallinnossa tarkoittaa. Työn toisena tavoitteena oli selvittää, miten Maanmittauslaitoksen kustannuslaskenta muuttuu vuoden 2014 vaihteessa tapahtuvan organisaatiouudistuksen johdosta, ja miten ja milloin tämä uusi kustannuslaskentajärjestelmä voidaan sertifioida. Diplomityö toteutettiin tapaustutkimuksena ja empiirinen aineisto kerättiin kvalitatiivisin menetelmin tekemällä organisaation sisäisiä ja ulkoisia haastatteluja. Maanmittauslaitoksen lisäksi haastateltavat osapuolet olivat VTV, Ernst & Young, sertifiointiprosessin lähes läpikäyneen Riista- ja kalatalouden tutkimuslaitoksen entinen ja nykyinen talouspäällikkö, Maa- ja metsätalousministeriö ja Valtiokonttori. Haastatteluiden lisäksi valtion virastoilta ja laitoksilta kysyttiin ovatko he kuulleet VTV:n tarjoamasta sertifiointipalvelusta ja ovatko he kiinnostuneita tästä kyseisestä palvelusta. Työn tuloksista käy ilmi, että VTV:n palvelu etenee samalla tavalla kuin mikä tahansa muu sertifiointiprosessi. VTV:n palvelu eroaa kuitenkin jonkin verran sertifioinnin perusrakenteesta, koska kustannuslaskentajärjestelmien tapauksessa ei ole laadittu yleisiä standardeja kustannuslaskennalle. Tämän vuoksi perusrakenteessa ei ole ollenkaan standardin omistajaa. Standardin omistajan paikalle sijoittuvat laki valtion talousarviosta ja asetus valtion talousarviosta. Maanmittauslaitoksen kustannuslaskenta muuttuu organisaatiouudistuksen myötä odotettua enemmän. Uuden organisaatiorakenteen vuoksi kustannuksia ei tarvitse vyöryttää toimintayksiköille, tulosyksiköille ja vastuualueille. Kustannukset vyörytetään jatkossa vain tuotteille ja projekteille. Maanmittauslaitoksen kannattaa sertifioida uusi kustannuslaskentajärjestelmänsä vuonna 2014, vaikka seuraavien vuosien aikana on tiedossa uusia muutoksia sekä organisaatioon, että tietojärjestelmiin. Ennen varsinaista tarkastusta Maanmittauslaitoksen kustannuslaskentajärjestelmä kuvattiin uudelleen.

Overview on the Cost-effectiveness of Maritime Safety Policy Instruments

Maritime safety is an issue that has gained a lot of attention in the Baltic Sea area due to the dense maritime traffic and transportation of oil in the area. Lots of effort has been paid to enhance maritime safety in the area. The risk exists that excessive legislation and other requirements mean more costs for limited benefit. In order to utilize both public and private resources efficiently, awareness is required of what kind of costs maritime safety policy instruments cause and whether the costs are in relation to benefits. The aim of this report is to present an overview of the cost-effectiveness of maritime safety policy instruments focusing on the cost aspect: what kind of costs maritime safety policy causes, to whom, what affects the cost-effectiveness and how cost-effectiveness is studied. The study is based on a literature review and on the interviews of Finnish maritime experts. The results of this study imply that cost-effectiveness is a complicated issue to evaluate. There are no uniform practices for which costs and benefits should be included in the evaluation and how they should be valued. One of the challenges is how to measure costs and benefits during the course of a longer time period. Often a lack of data erodes the reliability of evaluation. In the prevention of maritime accidents, costs typically include investments in ship structures or equipment, as well as maintenance and labor costs. Also large investments may be justifiable if they respectively provide significant improvements to maritime safety. Measures are cost-effective only if they are implemented properly. Costeffectiveness is decreased if a measure causes overlapping or repetitious work. Costeffectiveness is also decreased if the technology isn’t user-friendly or if it is soon replaced with a new technology or another new appliance. In future studies on the cost-effectiveness of maritime safety policy, it is important to acknowledge the dependency between different policy instruments and the uncertainty of the factors affecting cost-effectiveness. The costs of a single measure are rarely relatively significant and the effect of each measure on safety tends to be positive. The challenge is to rank the measures and to find the most effective combination of different policy instruments. The greatest potential offered for the analysis of cost-effectiveness of individual measures is their implementation in clearly defined risk situations, in which different measures are truly alternative to each other. Overall, maritime safety measures do not seem to be considered burdening for the shipping industry in Finland at the moment. Generally actors in the Finnish shipping industry seem to find maintaining a high safety level important and act accordingly.

CTQ process flow development and the impact for cost of quality

Tämä työ tehtiin Kone Industrial Oy:lle Major Projects yksikköön, laatuosastolle. Kone Major Projects yksikkö keskittyy erikoisiin ja suuriin hissi- ja liukuporras projekteihin. Työn tavoitteena oli luoda harmonisoitu prosessi hissikomponenttien laaduntarkkailua varten sekä tarkastella ja vertailla kustannussäästöjä, jota tällä uudella prosessilla voidaan saavuttaa. Tavoitteena oli saavuttaa 80-prosentin kustannussäästöt laatukustannuksissa uuden laatuprosessin avulla. Työn taustana ja tutkimusongelmana ovat lisääntyneet erikoisprojektit ja niiden myötä lisääntynyt laaduntarkkailun tarve. Ongelmana laaduntarkkailussa voitiin pitää harmonisoidun ja selkeän prosessin puuttumista C-prosessikomponenttien valmistuksessa. Lisäksi kehitysprosessin aikana luotiin vanhojen työkalujen pohjalta keskeinen laaduntarkkailutyökalu, CTQ-työkalu. Työssä käsitellään ensin Konetta yhtiönä ja selvitetään Koneen keskeisimmät prosessit työn taustaksi. Teoria osuudessa käsitellään prosessin kehitykseen liittyviä teorioita sekä yleisiä laatukäsitteitä ja esitetään teorioita laadun asemasta nykypäivänä. Lopuksi käsitellään COQ eli laatukustannusten teoriaa ja esitellään teoria PAF-analyysille, jota käytetään työssä laatukustannusten vertailuun case esimerkin avulla. Työssä kuvataan CTQ prosessin luominen alusta loppuun ja case esimerkin avulla testataan uutta CTQ prosessia pilottihankkeessa. Tässä case esimerkissä projektin bracket eli johdekiinnitysklipsi tuotetaan uuden laatuprosessin avulla sekä tehdään kustannusvertailu saman projektin toisen bracketin kanssa, joka on tuotettu ennen uuden laatuprosessin implementoimista. Työn lopputuloksena CTQ prosessi saatiin luotua ja sitä pystyttiin testaamaan käytännössä case esimerkin avulla. Tulosten perusteella voidaan sanoa, että CTQ prosessin käyttö vähentää laatukustannuksia huomattavasti ja helpottaa laadunhallintaa C-prosessikomponenttien tuotannossa.
