Osatuloutuksen kehittäminen osana ERP -investointia : Case Konecranes

Pitkäaikaishankkeen tuotot ja kustannukset tulee jakaa osatuloutuksen keinoin hankkeen valmistusajalle. Tässä tapaustutkimuksessa tarkastellaan pitkäaikaishankkeiden osatulouttamista osana ERP -investointia. Tavoite on kartoittaa kohdeyrityksen nykyistä osatuloutuskäytäntöä sekä tutkia tähän liittyviä mahdollisia muutoksia ja niiden vaikutuksia. Tutkimuksessa hahmotetaan ensin ERP:n toimintaa ja etenkin SAP:n tarjoamia mahdollisuuksia osatulouttamiselle. Tämän jälkeen selvitetään osatuloutusta koskevaa sääntelyä ja siihen liittyvää muutoshanketta. Empiirisessä osassa osatuloutusta käsitellään kohdeyrityksen näkökulmasta laskelmien, kirjallisuuden ja osallistuvan havainnoinnin kautta. Tutkimuksen mukaan case -yrityksen kannattaa toteuttaa osatuloutusta siten, että myös komponenttikustannukset kerryttävät valmistusastetta. Käytännössä tämän toteuttaminen on kuitenkin erittäin haasteellista. Tutkimus suositteleekin siirtymistä sisäisen laskennan osalta käyttämään komponenttien hinnoittelun pohjana standardikustannushintoja.

Methods for construction and analysis of computational models in systems biology : applications to the modelling of the heat shock response and the self-assembly of intermediate filaments

Systems biology is a new, emerging and rapidly developing, multidisciplinary research field that aims to study biochemical and biological systems from a holistic perspective, with the goal of providing a comprehensive, system- level understanding of cellular behaviour. In this way, it addresses one of the greatest challenges faced by contemporary biology, which is to compre- hend the function of complex biological systems. Systems biology combines various methods that originate from scientific disciplines such as molecu- lar biology, chemistry, engineering sciences, mathematics, computer science and systems theory. Systems biology, unlike “traditional” biology, focuses on high-level concepts such as: network, component, robustness, efficiency, control, regulation, hierarchical design, synchronization, concurrency, and many others. The very terminology of systems biology is “foreign” to “tra- ditional” biology, marks its drastic shift in the research paradigm and it indicates close linkage of systems biology to computer science. One of the basic tools utilized in systems biology is the mathematical modelling of life processes tightly linked to experimental practice. The stud- ies contained in this thesis revolve around a number of challenges commonly encountered in the computational modelling in systems biology. The re- search comprises of the development and application of a broad range of methods originating in the fields of computer science and mathematics for construction and analysis of computational models in systems biology. In particular, the performed research is setup in the context of two biolog- ical phenomena chosen as modelling case studies: 1) the eukaryotic heat shock response and 2) the in vitro self-assembly of intermediate filaments, one of the main constituents of the cytoskeleton. The range of presented approaches spans from heuristic, through numerical and statistical to ana- lytical methods applied in the effort to formally describe and analyse the two biological processes. We notice however, that although applied to cer- tain case studies, the presented methods are not limited to them and can be utilized in the analysis of other biological mechanisms as well as com- plex systems in general. The full range of developed and applied modelling techniques as well as model analysis methodologies constitutes a rich mod- elling framework. Moreover, the presentation of the developed methods, their application to the two case studies and the discussions concerning their potentials and limitations point to the difficulties and challenges one encounters in computational modelling of biological systems. The problems of model identifiability, model comparison, model refinement, model inte- gration and extension, choice of the proper modelling framework and level of abstraction, or the choice of the proper scope of the model run through this thesis.

Making Sense of Shared Leadership. A case study of leadership processes and practices without formal leadership structure in the team context

Leadership is essential for the effectiveness of the teams and organizations they are part of. The challenges facing organizations today require an exhaustive review of the strategic role of leadership. In this context, it is necessary to explore new types of leadership capable of providing an effective response to new needs. The presentday situations, characterized by complexity and ambiguity, make it difficult for an external leader to perform all leadership functions successfully. Likewise, knowledge-based work requires providing professional groups with sufficient autonomy to perform leadership functions. This study focuses on shared leadership in the team context. Shared leadership is seen as an emergent team property resulting from the distribution of leadership influence across multiple team members. Shared leadership entails sharing power and influence broadly among the team members rather than centralizing it in the hands of a single individual who acts in the clear role of a leader. By identifying the team itself as a key source of influence, this study points to the relational nature of leadership as a social construct where leadership is seen as social process of relating processes that are co-constructed by several team members. Based on recent theoretical developments concerned with relational, practice-based and constructionist approaches to the study of leadership processes, this thesis proposes the study of leadership interactions, working processes and practices to focus on the construction of direction, alignment and commitment. During the research process, critical events, activities, working processes and practices of a case team have been examined and analyzed with the grounded theory –approach in the terms of shared leadership. There are a variety of components to this complex process and a multitude of factors that may influence the development of shared leadership. The study suggests that the development process of shared leadership is a common sense -making process and consists of four overlapping dimensions (individual, social, structural, and developmental) to work with as a team. For shared leadership to emerge, the members of the team must offer leadership services, and the team as a whole must be willing to rely on leadership by multiple team members. For these individual and collective behaviors to occur, the team members must believe that offering influence to and accepting it from fellow team members are welcome and constructive actions. Leadership emerges when people with differing world views use dialogue and collaborative learning to create spaces where a shared common purpose can be achieved while a diversity of perspectives is preserved and valued. This study also suggests that this process can be supported by different kinds of meaning-making and process tools. Leadership, then, does not reside in a person or in a role, but in the social system. The built framework integrates the different dimensions of shared leadership and describes their relationships. This way, the findings of this study can be seen as a contribution to the understanding of what constitutes essential aspects of shared leadership in the team context that can be of theoretical value in terms of advancing the adoption and development process of shared leadership. In the real world, teams and organizations can create conditions to foster and facilitate the process. We should encourage leaders and team members to approach leadership as a collective effort that the team can be prepared for, so that the response is rapid and efficient.

Future trends of Finnish cement based construction

The construction material sector, as a capital intensive industry, is highly vulnerable to rapid fluctuations in the economic cycles. In Finland this was witnessed especially during the late 2000s, as in 2007 and 2008 the demand for several construction materials exceeded their supply and right after this, in 2009 the demand collapsed fast as a result of an international recession. These factors brought about the need to study the future trends of the market place of the commissioning company, Finnsementti Oy. As reliable short term market forecasts for the sector are difficult to compose, the study concentrates primarily in examining and identifying the trends that are likely to affect the Finnish cement industry, and as an extension, the concrete industry in a frame of 10 to 15 years. The study’s scope comprehends also the examination of the domestic construction sector, as it represents the end user industry of both cement and concrete. These motives for the study produce the research problem, which is to conduct a trend analysis for cement based building in the Finnish market area in the 2020s. The theoretical frame for composing a trend analysis in the case of this study is twofold. This is due to the fact that both, the macro and micro environments of the examined industries are studied. The main methods used are the PESTE-model (macro) and Porter’s five forces model (micro). The study applies a qualitative approach and the data is gathered by interviewing a group of experts from the cement, concrete and construction industries. The result of the paper is an overall trend analysis for the Finnish cement based building sector, which is based on ‘sub trend analyses’ concerning four identified sub-sectors of the Finnish construction industry. The results are a combination of findings from these sub-sectors and the analyzed data that deals with the studied sector’s macro and micro environment. The conclusions provide an overall picture of the examined sectors’ potential future as a whole and by defined sub-sectors of the construction industry. The recognition of future trends in different areas of the construction industry can be applied as a means for an industry actor’s decision making and in estimating the types of construction that are likely to grow or decline. Finally, based on the analyzed data and conclusions, the commissioning company is provided with a brief SWOT analysis, that provides additional tools for decision making and planning processes regarding the future.

Organisational learning and knowledge acquisition. A case study of internationalising manufacturers of wood-based prefabricated buildings

The study investigates organisational learning and knowledge acquisition of wood-based prefabricated building manufacturers. This certain group of case companies was chosen, because their management and their employees generally have a strong manufacturing and engineering background, while the housing sector is characterised by national norms, regulations, as well as local building styles. Considering this setting, it was investigated, how the case companies develop organisational learning capabilities, acquire and transfer knowledge for their internationalisation. The theoretical framework of this study constitutes the knowledge-based conceptualisation of internationalisation, which combines the traditional internationalisation process, as well as the international new venture perspective based on their commonalities in the knowledge-based view of the firm. Different theories of internationalisation, including the network-perspective, were outlined and a framework on organisational learning and knowledge acquisition was established. The empirical research followed a qualitative approach, deploying a multiple-case study with five case companies from Austria, Finland and Germany. In the study, the development of the wood-based prefabricated building industry and of the case companies are described, and the motives, facilitators and challenges for foreign expansion, as well as the companies’ internationalisation approaches are compared. Different methods of how companies facilitate the knowledge-exchange or learn about new markets are also outlined. Experience, market knowledge and personal contacts are considered essential for the internationalisation process. The major finding of the study is that it is not necessary to acquire the market knowledge internally in a slow process as proposed by the Uppsala model. In four cases companies engaged knowledge in symbiotic relations with local business partners. Thereby, the building manufacturers contribute their design and production capabilities, and in return, their local partners provide them with knowledge about the market and local regulations; while they manage the sales and construction operations. Thus, the study provides strong evidence for the propositions of network perspective. One case company developed the knowledge internally in a gradual process: it entered the market sequentially with several business lines, showing an increasing level of complexity. In both of the observed strategies, single-loop and double-loop learning processes occurred.

Exploring relationship between marketing and sales - a case study of B2B ICT solution sales

Following the current trend of companies in changing and developing their businesses from transactional approach to relationship and solution oriented approach has set new requirements to internal cooperation of companies too. The relationship between marketing and sales has been identified to be critical to company's success here, but surprisingly little is known about it. The purpose of this study was to deepen understanding of the relationship between sales and marketing in business-to-business sales from operative sales employees' perspectives in solution selling context. The aim was to develop an explorative analytical construction and framework of the interface. The study was conducted as a literature review and an empirical qualitative explorative single case study. The data was collected by conducting six thematic interviews with sales employees of the case company. Observing sales and marketing, written documents and other materials used in sales were used as secondary source of information. The data was analyzed using qualitative case study analysis methods. The findings of the study support previous research findings of the interface between marketing and sales but also bring new propositions as analytical framework to construct the interface. As such, the interface was found to be a multi-dimensional and complex dynamic construction. As results of this study, there was an exploratory framework constructed. The construction consists of three explorative contexts of the interface: internal context, relationship emphasizing context and solution selling context. These contexts are further divided into lower levels as an outcome of the analysis. In addition the identified contexts, there are also conceptual domains identified, which are common to all the contexts. The role of mutual, cross-functional knowledge creation was found to be central in the interface.

Creating risk measurement model to project portfolio management in construction company

This thesis was carried out as a case study of a company YIT in order to clarify the sev-erest risks for the company and to build a method for project portfolio evaluation. The target organization creates new living environment by constructing residential buildings, business premises, infrastructure and entire areas worth for EUR 1.9 billion in the year 2013. Company has noted project portfolio management needs more information about the structure of project portfolio and possible influences of market shock situation. With interviews have been evaluated risks with biggest influence and most appropriate metrics to examine. The major risks for the company were evaluated by interviewing the executive staff. At the same time, the most appropriate risk metrics were considered. At the moment sales risk was estimated to have biggest impact on company‟s business. Therefore project port-folio evaluation model was created and three different scenarios for company‟s future were created in order to identify the scale of possible market shock situation. The created model is tested with public and descriptive figures of YIT in a one-year-long market shock and the impact on different metrics was evaluated. Study was conducted using con-structive research methodology. Results indicate that company has notable sales risk in certain sections of business portfolio.

Development of category planning process in construction business

The aim of this thesis was to develop the category planning process in the case company operating in construction industry. As the interest in the field of research has just recently started to emerge towards the benefits of category management and planning, the theoretical background was derived from literature of subjects with a relation to category planning i.e. procurement strategy, purchasing portfolio model, information flow management and cost analysis. The background for the development of category planning process was derived from retail industry, to where the category planning is more researched. The empirical study was executed with mixed method approach: quantitative data of the categories was analyzed and qualitative data was gathered through semi-structured interview and discussions within the case company. As a result, the category planning process was critically analyzed and development proposals addressed for improving the process description. Additionally a tool was developed based on the empirical study to support the category planning process of the case company.

Projektitason suorituskykymittariston kehittäminen rakennusalalla: Case Rakennusliike X

Tutkimuksen aiheena on projektitason suorituskykymittariston kehittäminen rakennusalan yrityksessä. Suorituskyvyn mittaaminen on kehittynyt voimakkaasti 90 – luvulta alkaen johtuen kiihtyvässä muutosvauhdissa olevasta toimintaympäristöstä. Rakennusala on puhdasta projektiliiketoimintaa, jolloin toiminta on erittäin mo-nimuotoista ja riskit aikataulu-, kustannus- ja laatuongelmille ovat ilmeisiä. Myös suorituskyvyn mittaaminen rakennusalalla on tästä syystä esimerkiksi perinteistä tuotantotoimintaa haastavampaa. Tutkielma on laadullinen tutkimus, jossa tehdään haastatteluita kolmen eri rakentamisprojektin johdolle. Tutkimuksessa muodostettiin tämän pohjalta näkökulmia siitä, mitä ja miten rakentamisprojekteissa tulisi suorituskyvyn osalta mitata. Tutkimuksessa havaittiin, että suorituskyvyn kannalta kriittisintä olisi kyetä mittaamaan projektien alkuvaiheen prosesseja. Projektin toteutuksen aikana keskeisimmäksi nähtiin töiden ohjaamisen ja kustannusseurannan laatu. Myös henkilöstön inhimillisen pääoman vaikutusta painotettiin kaikilla projekteilla.

Yliopiston yrittäjämäisyyden sosiaalinen rakentuminen: case Aalto-yliopisto

Keskustelu yrittäjyyden sijoittumisesta yliopistojen tehtäväkenttään on muodostunut 2000-luvun aikana osaksi yhteiskunnallista ja maailmanlaajuista korkeakoulutuksen muutosta. Tämän tutkimuksen tarkoituksena on lisätä ymmärrystä yliopiston yrittäjämäisyyden sosiaalisesta rakentumisesta. Lähestyn yliopiston sisällä tuotettua moniäänistä yrittäjyyspuhetta yliopiston yrittäjämäisyyden todellisuuden representaationa, ja pyrin tekemään siitä selkoa kommunikaatioon kohdistuvan analyysin avulla. Ilmiön empiirinen tarkastelu pohjautuu Aalto-yliopistossa ja sitä edeltäneessä Teknillisessä korkeakoulussa vuosina 2006–2013 kerättyihin tekstiaineistoihin. Aineistojen tulkinta tuottaa monikerroksellista tietoa ilmiöstä niin yksilö- kuin organisaatiotasolla. Tarkastelen tutkimuksessani millaisia merkityksenantoja yrittäjyydelle ja yrittäjämäisyydelle annetaan yliopiston sisällä eri näkökulmista katsottuna, kun yliopisto käy läpi merkittävää organisaatiorakenteellista ja institutionaalista muutosta. Tutkimusasetelman neljä näkökulmaa perustuvat tekniikan alan jatko-opiskelijoiden puheeseen, TKK:n opetussuunnitelmatekstiin, Aalto-yliopiston opettajien puheeseen ja johdon tuottamaan strategiatekstiaineistoon. Tutkimuksen tulosten mukaan käynnissä on ollut akateemisten arvojen ja arvojärjestelmien laajentumisen aika ja tila, jossa yrittäjämäisyys astuu areenalle, mutta sen suppeat tulkinnat eivät tarjoa mahdollisuuksia ruohonjuuritason kiinnittymiseen akateemisesta kulttuurista käsin. Yrittäjyyden ja yrittäjämäisyyden saamat taloudelliskaupalliset merkitykset koetaan uhkaksi, eikä tilannetta helpota yleisesti uuvuttavaksi koettu rakenteellinen ja yhteiskunnallinen yliopiston muutosvaihe. Hallitsevat tarinalinjat kuten puhe kilpailukyvystä ja kilpailutilanteen kovenemisesta tuottavat odotusten viitekehyksen, joilla yliopiston toimintaa raamitetaan ulkoapäin. Yrittäjyyteen laajassa merkityksessä sisältyvät mahdollisuudet jäävät niin ikään hyödyntämättä, ja lukuisat edistämistoiminnot kilpistyvät sosiaalisesti rakentuviin esteisiin. Tässä tutkimuksessa rakentuva laajennettu yliopiston yrittäjämäisyyden viitekehys pyrkii palvelemaan moniäänistymisen tarkoitusta käsitteellisellä tasolla ja avaamaan uusia mahdollisuuksia yliopiston yrittäjämäisyyden edistämiselle.

Development of Project Logistics in Engineering, Procurement and Construction Projects

The aim of this Master’s Thesis is to develop project logistics functions in large scale en-gineering, procurement and construction projects. The background of the research topic is compounded from two separate subjects; OPAL Program and case study of an actual EPC project. The purpose is to examine Project Logistics process in accordance with OPAL Program as well as logistics process in focus EPC project. Both entities are researched by using the case study research methodology. Logistics process of the focus EPC project is described as well as presented and in addi-tion, logistics related findings and observations are introduced. Significant findings and observations are found from logistics costs as well as shipment volume estimations in the early phase of the focus ECP project. A notable finding is also that because goods were transported as readily assembled as possible it caused expensive oversized cargo deliveries. From findings and observation of the focus EPC project it can be derived that logistics has to be involved in the early sales phase in order to receive more accurate logistics cost esti-mations for project deliveries. It is also noticed that in order to obtain savings in logistics costs, oversized deliveries must be avoided.

Successful new venturing process implemented by the founding entrepreneur: A case of Finnish sawmill industry

The fundamental purpose of this research is to emphasise a founding entrepreneur’s own role in the construction of a successful business story, with the focus being on the analysis of the entrepreneur’s activities. The theoretical section sheds light on the heterogeneous nature of existing performance research and, thereby, opens the way for the behavioural approach research of entrepreneurs in the field of new venture performance research. This research can be seen to be in line with the latest trends in entrepreneurship research, which question the applicability of different organisational theories in entrepreneurship research. For this reason, the founding entrepreneur has been chosen, instead of the company, to be the unit of analysis in this research in order to lighten the link in question while developing and refining new knowledge in the field of entrepreneurship. The empirical section of this research focuses on the entrepreneur’s own actions or behaviours that can be seen to be associated with the company’s success. Although some of these actions may resemble the strategic actions of a company as defined in strategic management literature, these actions taken by the entrepreneur themselves must be distinguished from the different organisational actions. Usually, an entrepreneur makes decisions rather independently, mainly on basis of their own intuition and prevailing market conditions, whereas organisational actions are very systematic, and each decision involves many different people. For this reason, an entrepreneur’s actions must be distinguished from organisational actions. In additional to different action paths, the empirical data collected for this research also offers almost unambiguous proof that the actions taken by an entrepreneur at the different stages of a company’s development do play a crucial role in the success of the companies studied in this research. In this way, it is possible to identify a significant link between the behavioural approach research of entrepreneurs and new venture performance research. Due to a lack of behavioural research into founding entrepreneurs, this research has utilised a qualitative (hermeneutic) research approach. The researcher strove to establish a particularly close connection with the entrepreneurs that were studied here and, thus, understand the actions taken at the different stages of their companies’ development as well as the motives and fundamental purposes of these actions. It would not have been possible to manage such profound data that focuses on causalities by using quantitative methods. In addition to interviews, this research used corporate histories of the companies for collecting some of the research data. These corporate histories can be considered excellent tools for the researcher to obtain a preliminary understanding and can, thereby, be seen to have laid the ground for more in-depth and diverse analyses.

The Formation Of Internationalization Strategies Within The Construction Industry:Vision and Strategy

Internationalization represents a complex topic that has been researched for quite some time. However, since it continues to be extremely current a topic, its significance has not diminished, but maybe even increased in importance. Companies today face extreme pressure to enter new markets in the hope of growing, becoming more profitable, increasing market share, attracting new customers and meeting the requirements of its share- and stakeholders. In the increasingly global business environment of today, companies are facing both challenges and possible advantages of internationalization. Few companies are not operating internationally and it is becoming the question of ‘Why not?’ rather than ‘Why?’ to internationalize business operations. Internationalization and the importance of strategy are discussed in this research from the viewpoint of three case companies that were interviewed about internationalization strategies. This research project is a qualitative study that answers the research question of How is a business strategy constructed for entering a new market? The sub-questions are • How are goals set and what indicators are used to monitor the achievement of these goals? • What are the key characteristics of a strategy implementation process? The research method chosen for this study is a multiple-case study. Three case companies were chosen for the interviews in order to gain in-depth data of internationalization strategies within the construction industry.

Marginal/minority popular music : the concept of the "third space" and the case for "hybridities" of cultures/identities /

The topic of this thesis is marginaVminority popular music and the question of identity; the term "marginaVminority" specifically refers to members of racial and cultural minorities who are socially and politically marginalized. The thesis argument is that popular music produced by members of cultural and racial minorities establishes cultural identity and resists racist discourse. Three marginaVminority popular music artists and their songs have been chosen for analysis in support of the argument: Gil Scott-Heron's "Gun," Tracy Chapman's "Fast Car" and Robbie Robertson's "Sacrifice." The thesis will draw from two fields of study; popular music and postcolonialism. Within the area of popular music, Theodor Adorno's "Standardization" theory is the focus. Within the area of postcolonialism, this thesis concentrates on two specific topics; 1) Stuart Hall's and Homi Bhabha's overlapping perspectives that identity is a process of cultural signification, and 2) Homi Bhabha's concept of the "Third Space." For Bhabha (1995a), the Third Space defines cultures in the moment of their use, at the moment of their exchange. The idea of identities arising out of cultural struggle suggests that identity is a process as opposed to a fixed center, an enclosed totality. Cultures arise from historical memory and memory has no center. Historical memory is de-centered and thus cultures are also de-centered, they are not enclosed totalities. This is what Bhabha means by "hybridity" of culture - that cultures are not unitary totalities, they are ways of knowing and speaking about a reality that is in constant flux. In this regard, the language of "Otherness" depends on suppressing or marginalizing the productive capacity of culture in the act of enunciation. The Third Space represents a strategy of enunciation that disrupts, interrupts and dislocates the dominant discursive construction of US and THEM, (a construction explained by Hall's concept of binary oppositions, detailed in Chapter 2). Bhabha uses the term "enunciation" as a linguistic metaphor for how cultural differences are articulated through discourse and thus how differences are discursively produced. Like Hall, Bhabha views culture as a process of understanding and of signification because Bhabha sees traditional cultures' struggle against colonizing cultures as transforming them. Adorno's theory of Standardization will be understood as a theoretical position of Western authority. The thesis will argue that Adorno's theory rests on the assumption that there is an "essence" to music, an essence that Adorno rationalizes as structure/form. The thesis will demonstrate that constructing music as possessing an essence is connected to ideology and power and in this regard, Adorno's Standardization theory is a discourse of White Western power. It will be argued that "essentialism" is at the root of Western "rationalization" of music, and that the definition of what constitutes music is an extension of Western racist "discourses" of the Other. The methodological framework of the thesis entails a) applying semiotics to each of the three songs examined and b) also applying Bhabha's model of the Third Space to each of the songs. In this thesis, semiotics specifically refers to Stuart Hall's retheorized semiotics, which recognizes the dual function of semiotics in the analysis of marginal racial/cultural identities, i.e., simultaneously represent embedded racial/cultural stereotypes, and the marginal raciaVcultural first person voice that disavows and thus reinscribes stereotyped identities. (Here, and throughout this thesis, "first person voice" is used not to denote the voice of the songwriter, but rather the collective voice of a marginal racial/cultural group). This dual function fits with Hall's and Bhabha's idea that cultural identity emerges out of cultural antagonism, cultural struggle. Bhabha's Third Space is also applied to each of the songs to show that cultural "struggle" between colonizers and colonized produces cultural hybridities, musically expressed as fusions of styles/sounds. The purpose of combining semiotics and postcolonialism in the three songs to be analyzed is to show that marginal popular music, produced by members of cultural and racial minorities, establishes cultural identity and resists racist discourse by overwriting identities of racial/cultural stereotypes with identities shaped by the first person voice enunciated in the Third Space, to produce identities of cultural hybridities. Semiotic codes of embedded "Black" and "Indian" stereotypes in each song's musical and lyrical text will be read and shown to be overwritten by the semiotic codes of the first person voice, which are decoded with the aid of postcolonial concepts such as "ambivalence," "hybridity" and "enunciation."
