Key success factors and process for IT project portfolio management

The importance of Information Technology (IT) in the business environment is continuously growing. This stimulates the increase of size, complexity and number of IT projects and raises the need for IT Project Portfolio Management (IT PPM). While being actively discussed for the last few decades, IT PPM has a short history of practical implementation. This creates inconsistency in the views of different authors and provides an opportunity for additional research. As a first step, this research explores the existing studies and brings together the views of different authors on IT PPM. As a result, a high-level IT PPM Process Cycle and a set of Key Success Factors for IT PPM are proposed. IT PPM Process Cycle gives an overview of the main elements of IT PPM process, while the set of Key Success Factors provides a number of factors that should be considered during the implementation. As a second step, both theoretical deliverables are empirically tested by a case study and a survey conducted in a big multinational company. The case study is used to analyze process framework of the studied company towards the developed IT PPM Process Cycle. Subsequently, a survey was conducted among subject matter experts of the same company to evaluate the importance and relevance of the proposed Key Success Factors. Finally, this thesis concludes with findings made during the case study and provides an empirically tested selection of factors to be taken into account. These two deliverables can be used by both academics and practitioners to close the gaps in existing literature and assist in IT PPM implementation.

Success Factors of Accelerators

There is wide interest in new business creation especially in high-growth companies because of the transition from the industrial era to the information era. Previously traditional industry has been a major employer but now industrial employment is moving to countries that provide cheaper labor, and therefore Western countries are reaching for new solutions that could safeguard the current stage of economic wealth. High-growth companies are seen as one opportunity. The aim of this study is to clarify the success factors of accelerators. Acceleration is a relatively new phenomenon, which has its roots in the venture capital industry. Their fundamental goal is to create high-growth companies that have global market potential. Accelerators could be defined as venture-to-capital actors that bridge the competence and equity gaps of startups. The access to the knowledge and funding are the prerequisites of the existence of accelerator. This research was qualitative and based on 18 semi-structured or thematic interviews with 15 accelerators and topic related professionals from Finland, Estonia, Denmark, Germany, the UK and the US. The data was analyzed with a content analysis approach. The study revealed three fundamental preconditions for success. First, the deep business knowledge and access to relevant networks is a foundation and fundamental precondition. Second, the ability to transfer knowledge from the accelerator to startups has significant importance. And third, the dynamics of an accelerator organization can restrict the use of business knowledge. Moreover, the attraction of an accelerator and team selection are crucial issues for success.

The Impact of Service Quality and Relationship Quality on Customer Loyalty in Business-to-Business Context

The main objective of this Master’s Thesis was to examine the interrelations of service quality and relationship quality (customer satisfaction, trust and commitment), and find out are they antecedents for customer loyalty in business-to-business context. Literature review revealed some research gaps concerning these focal concepts, which should be studied more closely. The theoretical basis for this research was collected for evaluating a strategic increase of customer’s perceptions of service quality and relationship quality as well as customer loyalty in business-to-business environment, and it was tested empirically in a sample of 164 corporate customers, who responded to the Internet-based survey. The measures, used in the survey, were first assessed by using confirmatory factor analysis (CFA), and then the hypothesized relationships were further verified using structural equation modeling (SEM) in LISREL 8.80. There was found support for a half of the hypothesized construct relations. The results of the research confirm the direct influence of trust and commitment on customer loyalty. Also, service quality turned out to have an indirect impact on customer loyalty through trust. No support, however, was offered for the proposed impact of customer satisfaction on loyalty in this case. The research provides managerially relevant and actionable results that may help service providers execute more specific customer relationship quality strategies that lead to higher customer loyalty.

Analysis of Regular and Irregular Dynamics of a Non Ideal Gear Rattling Problem

This paper presents a study on the dynamics of the rattling problem in gearboxes under non-ideal excitation. The subject has being analyzed by a number of authors such as Karagiannis and Pfeiffer (1991), for the ideal excitation case. An interesting model of the same problem by Moon (1992) has been recently used by Souza and Caldas (1999) to detect chaotic behavior. We consider two spur gears with different diameters and gaps between the teeth. Suppose the motion of one gear to be given while the motion of the other is governed by its dynamics. In the ideal case, the driving wheel is supposed to undergo a sinusoidal motion with given constant amplitude and frequency. In this paper, we consider the motion to be a function of the system response and a limited energy source is adopted. Thus an extra degree of freedom is introduced in the problem. The equations of motion are obtained via a Lagrangian approach with some assumed characteristic torque curves. Next, extensive numerical integration is used to detect some interesting geometrical aspects of regular and irregular motions of the system response.

The Influence of Network Competence on Internationalization of SMEs

This study focuses on the relationship between organizational network competence and the internationalization process of small- and medium sized enterprises (SMEs). Over recent decades, the global business environment has become increasingly conducive to internationalization of small firms. A central facilitating factor in the process has been the emergence of networked business relationships between internationalizing firms. Research on SME internationalization has found that certain types of structures and dynamics of business networks allow SMEs access to the resources they need to enter foreign markets. This consequently means that their internationalization often becomes to depend on the networks they are embedded in. However, research so far has mostly ignored the possibility that the organizational ability to develop and manage business network relationships, network competence, may be a major underlying factor in determining how well SMEs can leverage their network relationships to enter foreign markets and consequently may determine in large part how successful their internationalization process turns out to be. This study aims to respond to those gaps, by empirically examining how the development of network competence in internationalizing SMEs influences the internationalization outcomes that they can expect, and how such network competence is conceptualized and developed. Using a mixed methods approach, survey data collected from 298 Finnish SMEs across five industry sectors is first used to examine how levels of network competence are related to internationalization propensity of SMEs and their subsequent international performance, growth and profitability as internationally operating firms. In order to illustrate in more detail the ways in which network competence is conceptualized and how it develops during the internationalization process of an SME, qualitative data from internationally operating Finnish SMEs are used. Longitudinal interview data of an internationalizing Finnish SME is accompanied by data gathered through a series of semistructured interviews of Finnish and Russian managers involved in mutual business relationship dyads. Structurally, this thesis examines the research issue as an article-based dissertation, consisting of five journal and conference publications. Three of these publications are based on the quantitative data, and the remaining two apply the qualitative interview data. The results find several aspects where network competence has a positive influence on the success of internationalizing SMEs, how it develops and what it entails conceptually in this context. Quantitatively, the level of network competence is found to have a positive relationship to various internationalization outcomes, including the propensity of SMEs to enter foreign markets and on their subsequent international performance, their growth and their profitability. Additionally, the positive relationship is divided between the relationship-specific and cross-relational dimension of network competence, in that the influence of the former is relevant for the propensity to internationalize, while the latter is for the growth and profitability of the already internationalized SMEs. Qualitatively, the results suggest, firstly, that the development process of network competence does not necessarily precede the start of the internationalization process, but may occur through a gradual learning process alongside it. And secondly, the results also imply that the conceptualization of network competence by Finnish managers of internationally operating Finnish SMEs is structurally distinct from that of their culturally distinct partner managers in Russia. This study contributes to the literature on SME internationalization in several ways. Firstly, it introduces operationalized organizational competencies to the literature on internationalization of SMEs, which has so far mainly examined the influence of business networking on the internationalization process without having such an organizational viewpoint. Furthermore, this study provides a multi-level analysis of the determinants of successful SME internationalization, by examining various strategic and performance outcomes across the process. These results also contribute to the literature on organizational strategy of internationalizing SMEs, by clarifying how different dimensions of business networking may be optimal in different phases of the internationalization process. Conceptually, the results of this study contribute to the literature on competence development and SME internationalization, by illustrating how the development process of network competence may occur during internationalization process. Thus, they also contribute to the discussion on how SMEs are able to influence the dynamics and structures of their business networks over time. Finally, this study contributes to the literature on the role of culture in the internationalization process, by implying that the cultural background of the manager of the SME may determine whether business networking and network competence is seen as an organizational-level or an individual level capability. The study also includes some additional contributions to the literature on dynamic capabilities in strategic management, and on that of strategic business networks. These include further clarifying the exact nature and tangibility of dynamic capabilities, and being one of the first studies to introduce constructs from both dynamic capabilities and business network literature to the field of international entrepreneurship. And finally, the study also has some contribution on the two streams of literature, in illustrating how both dyadic and network-level capabilities may be relevant, depending on the current strategic goals and market position of the firm.

Building organizational creativity – a multitheory and multilevel approach for understanding and stimulating organizational creativity

Organizational creativity is increasingly important for organizations aiming to survive and thrive in complex and unexpectedly changing environments. It is precondition of innovation and a driver of an organization’s performance success. Whereas innovation research increasingly promotes high-involvement and participatory innovation, the models of organizational creativity are still mainly based on an individual-creativity view. Likewise, the definitions of organizational creativity and innovation are somewhat equal, and they are used as interchangeable constructs, while on the other hand they are seen as different constructs. Creativity is seen as generation of novel and useful ideas, whereas innovation is seen as the implementation of these ideas. The research streams of innovation and organizational creativity seem to be advancing somewhat separately, although together they could provide many synergy advantages. Thereby, this study addresses three main research gaps. First, as the knowledge and knowing is being increasingly expertized and distributed in organizations, the conceptualization of organizational creativity needs to face that perspective, rather than relying on the individual-creativity view. Thus, the conceptualization of organizational creativity needs clarification, especially as an organizational-level phenomenon (i.e., creativity by an organization). Second, approaches to consciously build organizational creativity to increase the capacity of an organization to demonstrate novelty in its knowledgeable actions are rare. The current creativity techniques are mainly based on individual-creativity views, and they mainly focus on the occasional problem-solving cases among a limited number of individuals, whereas, the development of collective creativity and creativity by the organization lacks approaches. Third, in terms of organizational creativity as a collective phenomenon, the engagement, contributions, and participation of organizational members into activities of common meaning creation are more important than the individualcreativity skills. Therefore, the development approaches to foster creativity as social, emerging, embodied, and collective creativity are needed to complement the current creativity techniques. To address these gaps, the study takes a multiparadigm perspective to face the following three objectives. The first objective of this study is to clarify and extend the conceptualization of organizational creativity. The second is to study the development of organizational creativity. The third is to explore how an improvisational theater based approach fosters organizational creativity. The study consists of two parts comprising the introductory part (part I) and six publications (part II). Each publication addresses the research questions of the thesis through detailed subquestions. The study makes three main contributions to the research of organizational creativity. First, it contributes toward the conceptualization of organizational creativity by extending the current view of organizational creativity. This study views organizational creativity as a multilevel construct constituting both of individual and collective (group and organizational) creativity. In contrast to current views of organizational creativity, this study bases on organizational (collective) knowledge that is based on and demonstrated through the knowledgeable actions of an organization as a whole. The study defines organizational creativity as an overall ability of an organization to demonstrate novelty in its knowledgeable actions (through what it does and how it does what it does).Second, this study contributes toward the development of organizational creativity as multi-level phenomena, introducing developmental approaches that face two or more of these levels simultaneously. More specifically, the study presents the cross-level approaches to building organizational creativity, by using an approach based in improvisational theater and considering assessment of organizational renewal capability. Third, the study contributes on development of organizational creativity using an improvisational theater based approach as twofold meaning. First, it fosters individual and collective creativity simultaneously and builds space for creativity to occur. Second, it models collective and distributed creativity processes, thereby, contributing to the conceptualization of organizational creativity.

Fitossociologia de um remanescente de mata mesófila semidecídua urbana, bosque John Kennedy, Araguari, MG, Brasil

RESUMO - (Fitossociologia de um remanescente de mata mesófila semidecídua urbana, Bosque John Kennedy, Araguari, MG, Brasil). Um estudo fitossociológico foi realizado no Bosque Municipal John Kennedy, município de Araguari, MG (48°11'19''W e 18°38'35''S). O bosque, com aproximadamente 11,2 ha, situa-se no perímetro urbano e é formado principalmente por uma mata mesófila semidecídua. No levantamento fitossociológico realizado, amostraram-se, em 1,2 ha, 1827 indivíduos, pertencentes a 46 famílias; 88 gêneros e 113 espécies, com um índice de diversidade de Shannon de H' = 3,75 nats/indivíduo. Os parâmetros fitossociológicos indicam as espécies mais importantes: Licania apetala, Micrandra elata, Copaifera langsdorffii, Astronium nelson-rosae e Alchornea glandulosa, e as famílias mais importantes: Chrysobalanaceae, Euphorbiaceae, Caesalpinaceae, Mimosaceae e Anacardiaceae. A ocorrência de algumas espécies incluidas entre as principais, caracteristicamente, pioneiras (Alchornea glandulosa e Piptocarpha macropoda), ou secundárias (Didymopanax macrocarpum e Maprounea guianensis), pode ser explicada pela existência de algumas áreas de clareiras, no interior dessa mata semidecídua, mas que, aparentemente, ainda não interferiram na estrutura da mata como um todo.

Produção de serapilheira em clareiras de uma floresta estacional semidecidual no município de Campinas, SP

Estudou-se a produção de serapilheira em 10 clareiras naturais da Reserva Municipal de Santa Genebra (22°49'45"S e 47°06'33"W) em Campinas, SP. Foram utilizados 30 coletores de madeira de 0,5 x 0,5 m com fundo em tela de náilon com 1,0 mm² de malha, colocados a 10 cm acima da superfície do solo. As coletas foram realizadas mensalmente de janeiro a dezembro de 1997. Em laboratório, o material depositado nos coletores foi triado nas frações folhas, ramos (até 2,0 cm de diâmetro), flores e frutos, seco em estufa a 70°C e pesado em balança analítica. A produção anual de serapilheira foi estimada para as clareiras como um todo em 5968 kg.ha­1, sendo a fração foliar dominante (75,87% do peso seco total), seguida das frações ramos com 19,27%, frutos com 3,17% e flores com 1,69%. A produção de serapilheira foi contínua ao longo do ano, apresentando um modelo sazonal, com os maiores valores no final da estação seca, atingindo valor máximo em setembro. Entre clareiras, a produção de serapilheira correlacionou-se significativa e positivamente com a dominância de espécies pioneiras.

Germination of seeds of tropical pioneer species under controlled and natural conditions

Seed germination of eight tropical pioneer species (Cecropia hololeuca, C. pachystachya, C. glazioui, Solanum gracillimum, S. granuloso-leprosum, S. tabacifolium, Croton floribundus and Miconia chamissois) was studied. In controlled conditions, alternating temperatures were tested from 5 to 25 °C. Low Red:Far Red ratios (R:FR) were also examined. In the field, germination was evaluated in gaps and under the canopy. With the exception of Croton floribundus, all other species were photoblastic in that higher germination percentages were found under light conditions (S. tabacifolium behaved as a negative photoblastic species at some temperatures). No relationship was found between germination percentage and alternating temperature. Germination was markedly reduced under low R:FR ratios. Alternating temperature is not the main factor affecting field germination. The low R:FR ratio under the canopy seems to be the crucial factor affecting germination.

Factors Affecting Customer Profitability: a Bibliometric Study

The first objective of the thesis is to find out which factors impact on customer profitability has been studied in scientific articles. The second objective is to find out the main authors and publishers from the subject area. Expectations were to find factors from marketing and management accounting literature, but this study did not succeed to gather management accounting perspective on the subject area. This study used bibliometric methods. The data for this study was collected manually from Scopus and Web of Science databases. Search words resulted 770 articles and from those 82 were included to further analyze. Descriptive analysis, citation analysis and content analysis were made. Bibexcel and Pajek software were used in this study. Publication activity was concentrated on years 2004-2013. The most productive author around the subject area is Kumar Vipin from Georgia State University (USA). A multiple customer profitability factors were identified. A lot of research was made for example about satisfaction, relationship duration, loyalty, marketing actions and customer equity drivers. The research is concentrated on service sector. The results are suggesting that there are research gaps in business-to-business and manufacturing sector.
