Studies on coordination of systems development process

This thesis examines coordination of systems development process in a contemporary software producing organization. The thesis consists of a series of empirical studies in which the actions, conceptions and artifacts of practitioners are analyzed using a theory-building case study research approach. The three phases of the thesis provide empirical observations on different aspects of systemsdevelopment. In the first phase is examined the role of architecture in coordination and cost estimation in multi-site environment. The second phase involves two studies on the evolving requirement understanding process and how to measure this process. The third phase summarizes the first two phases and concentrates on the role of methods and how practitioners work with them. All the phases provide evidence that current systems development method approaches are too naïve in looking at the complexity of the real world. In practice, development is influenced by opportunity and other contingent factors. The systems development processis not coordinated using phases and tasks defined in methods providing universal mechanism for managing this process like most of the method approaches assume.Instead, the studies suggest that managing systems development process happens through coordinating development activities using methods as tools. These studies contribute to the systems development methods by emphasizing the support of communication and collaboration between systems development participants. Methods should not describe the development activities and phases in a detail level, butshould include the higher level guidance for practitioners on how to act in different systems development environments.

Scientific creativity and diversity of physical work environment: framework development

The aim of this research was to develop a framework to analyze how physical environment influences scientific creativity. Due to the relative novelty of this topic, there is still a gap in the unified method to study connection between physical environment and creativity. Therefore, in order to study this issue deeply, the qualitative method was used (interviews and qualitative questionnaire). Scientists (PhD students and senior researchers) of Graduate School of Management were interviewed to build the model and one expert interview was conducted to assess its validity. The model highlights several dimensions via which physical environment can influence scientific creativity: Comfort, Instruments and Diversity. Comfort and Instruments are considered to be related mostly to productivity, an initial requirement for creativity, while Diversity is the factor responsible for supporting all the stages of scientific creative process. Thus, creative physical environment is not one place by its nature, but an aggregative phenomenon. Due to two levels of analysis, the model is named the two-level model of creative physical environment.

Adventures of Ludom: a Videogame Geneontology

Within the last few decades, the videogame has become an important media, economic, and cultural phenomenon. Along with the phenomenon’s proliferation the aspects that constitute its identity have become more and more challenging to determine, however. The persistent surfacing of novel ludic forms continues to expand the conceptual range of ‘games’ and ‘videogames,’ which has already lead to anxious generalizations within academic as well as popular discourses. Such generalizations make it increasingly difficult to comprehend how the instances of this phenomenon actually work, which in turn generates pragmatic problems: the lack of an applicable identification of the videogame hinders its study, play, and everyday conceptualization. To counteract these problems this dissertation establishes a geneontological research methodology that enables the identification of the videogame in relation to its cultural surroundings. Videogames are theorized as ‘games,’ ‘puzzles,’ ‘stories,’ and ‘aesthetic artifacts’ (or ‘artworks’), which produces a geneontological sequence of the videogame as a singular species of culture, Artefactum ludus ludus, or ludom for short. According to this sequence, the videogame’s position as a ‘game’ in the historicized evolution of culture is mainly metaphorical, while at the same time its artifactuality, dynamic system structure, time-critical strategic input requirements and aporetically rhematic aesthetics allow it to be discovered as a conceptually stable but empirically transient uniexistential phenomenon that currently thrivesbut may soon die out.

Sotilasyksikön integraatio – koulutuskulttuurien kohtaaminen ja konfliktit

Tutkimuksen kohteena on yksi sotilasyksikkö, Reserviupseerikoulun Esikunta- ja viestikomppania. Kyseisessä yksikössä koulutetaan reservinupseereita sotilaspo-liisi-, huolto-, johtamisjärjestelmä- ja komentopaikkatehtäviin. Sotilaspoliisilinja ja huoltolinja ovat liittyneet yksikköön vuoden 2014 lopulla. Tämä integraatio on saanut aikaan tiedonintressin koulutuslinjojen kulttuureihin liittyen. Tarkoituksena on selvittää miten linjojen koulutuskulttuurit poikkeavat toisistaan ja mitä kulttuurien integraatiossa tapahtuu. Tutkimuksen tavoitteena on myös antaa suosituksia yksikölle mahdollisten kulttuuriristiriitojen ja konfliktien hallitsemiseksi. Tutkimus on luonteeltaan sosiaaliantropologista kauppatieteellistä kulttuurintutki-musta. Taustatieteinä ovat liiketaloustiede, antropologia, sosiologia ja osittain or-ganisaatiopsykologia. Tutkimusote on laadullinen ja aineiston hankinnan mene-telminä on käytetty yksikön kouluttajien haastatteluja ja osallistuvaa havainnointia. Tutkimusaineisto on analysoitu teoriaohjaavaa laadullista sisällönanalyysiä käyttäen. Analyysin tavoitteena oli tunnistaa erot integroituvissa koulutuskulttuureissa, ymmärtää eroista johtuvien konfliktien logiikkaa ja tarkastella kulttuurien vuotamisen logiikkaa. Esikunta- ja viestikomppanian koulutuskulttuurien erilaisuutta analysoitiin seuraavien teoriateemojen kautta: oppilaskäsitys, suhtautuminen upseerioppilaisiin, artefaktit (koulutusmenetelmät), arvot, asenteet ja kouluttamisen syväoletukset. Koulutuskulttuurien kohtaamista analysoitiin psykologisen omistajuuden, reviirikäyttäytymisen ja kulttuurin vuotamisen teorioiden kautta. Tutkimustulokset osoittavat, että kulttuurilla todella on merkitystä sotilasorganisaa-tion integraatiotilanteessa. Esikunta- ja viestikomppanian koulutuskulttuureissa on havaittavissa huomattavia eroja, mutta myös samankaltaisuuksia. Kulttuurien erot johtavat ristiriitaisuuksiin, konflikteihin, reviirikäyttäytymiseen ja saavat ihmiset osoittamaan mieltään eri tavoin. Toisaalta kulttuuripiirteillä on myös taipumusta vuotaa ympäristöön nopeuttaen uusien organisaation osien sopeutumista. Johtajan rooli kulttuurien hallinnassa on keskeinen. Johtajan oma kulttuuriorientaatio voi johtaa konflikteihin, mutta toisaalta myös ratkaista niitä. Tärkeimpänä johtopäätöksenä on, että suuressa sotilasyksikössä kannattaisi laatia strategia eli suunnitelma kulttuurin johtamista varten silloin, kun integraatio on tapahtumassa. Strategian avulla voidaan ottaa kantaa useisiin kulttuurillisiin ristiriitoihin, joita siis Esikunta- ja viestikomppaniankin tapauksessa ilmenee. Koko yksikön henkilöstä kannattaisi sitouttaa ja ottaa mukaan strategian laadintaan. Strategia selventäisi esimerkiksi yksikön arvoja, visiota, missiota, tehtäviä, erilaisten linjojen erityisasemaa ja poikkeuksia, haluttua ja toivottua toimintaa ja asennetta, palkitsemiskäytäntöjä, toisin sanoen kulttuurin eri tekijöitä. Strategia ei ole vain liiketaloudellinen tulosyksikön pitkän tähtäimen pakollinen työkalu, vaan myös sotilasorganisaation kulttuurin johtamisen väline.

How Lean Six Sigma and Agile principles optimize ITIL-based processes

Imagine the potential implications of an organization whose business and IT processes are well aligned and are capable of reactively and proactively responding to the external and internal changes. The Philips IT Infrastructure and Operations department (I&O) is undergoing a series of transformation activities to help Philips business keeping up with the changes. I&O would serve a critical function in any business sectors; given that the I&O’s strategy switched from “design, build and run” to “specify, acquire and performance manage”, that function is amplified. In 2013, I&O’s biggest transforming programme I&O Futures engaged multiple interdisciplinary departments and programs on decommissioning legacy processes and restructuring new processes with respect to the Information Technology Internet Library (ITIL), helping I&O to achieve a common infrastructure and operating platform (CI&OP). The author joined I&O Futures in the early 2014 and contributed to the CI&OP release 1, during which a designed model Bing Box and its evaluations were conducted through the lens of six sigma’s structured define-measure-analyze-improve-control (DMAIC) improvement approach. This Bing Box model was intended to firstly combine business and IT principles, namely Lean IT, Agile, ITIL best practices, and Aspect-oriented programming (AOP) into a framework. Secondly, the author implemented the modularized optimization cycles according to the defined framework into Philips’ ITIL-based processes and, subsequently, to enhance business process performance as well as to increase efficiency of the optimization cycles. The unique of this thesis is that the Bing Box model not only provided comprehensive optimization approaches and principles for business process performance, but also integrated and standardized optimization modules for the optimization process itself. The research followed a design research guideline that seek to extend the boundaries of human and organizational capabilities by creating new and innovative artifacts. The Chapter 2 firstly reviewed the current research on Lean Six Sigma, Agile, AOP and ITIL, aiming at identifying the broad conceptual bases for this study. In Chapter 3, we included the process of constructing the Bing Box model. The Chapter 4 described the adoption of Bing Box model: two-implementation case validated by stakeholders through observations and interviews. Chapter 5 contained the concluding remarks, the limitation of this research work and the future research areas. Chapter 6 provided the references used in this thesis.

Use of airborne laser scanner data in demanding forest conditions

Most of the applications of airborne laser scanner data to forestry require that the point cloud be normalized, i.e., each point represents height from the ground instead of elevation. To normalize the point cloud, a digital terrain model (DTM), which is derived from the ground returns in the point cloud, is employed. Unfortunately, extracting accurate DTMs from airborne laser scanner data is a challenging task, especially in tropical forests where the canopy is normally very thick (partially closed), leading to a situation in which only a limited number of laser pulses reach the ground. Therefore, robust algorithms for extracting accurate DTMs in low-ground-point-densitysituations are needed in order to realize the full potential of airborne laser scanner data to forestry. The objective of this thesis is to develop algorithms for processing airborne laser scanner data in order to: (1) extract DTMs in demanding forest conditions (complex terrain and low number of ground points) for applications in forestry; (2) estimate canopy base height (CBH) for forest fire behavior modeling; and (3) assess the robustness of LiDAR-based high-resolution biomass estimation models against different field plot designs. Here, the aim is to find out if field plot data gathered by professional foresters can be combined with field plot data gathered by professionally trained community foresters and used in LiDAR-based high-resolution biomass estimation modeling without affecting prediction performance. The question of interest in this case is whether or not the local forest communities can achieve the level technical proficiency required for accurate forest monitoring. The algorithms for extracting DTMs from LiDAR point clouds presented in this thesis address the challenges of extracting DTMs in low-ground-point situations and in complex terrain while the algorithm for CBH estimation addresses the challenge of variations in the distribution of points in the LiDAR point cloud caused by things like variations in tree species and season of data acquisition. These algorithms are adaptive (with respect to point cloud characteristics) and exhibit a high degree of tolerance to variations in the density and distribution of points in the LiDAR point cloud. Results of comparison with existing DTM extraction algorithms showed that DTM extraction algorithms proposed in this thesis performed better with respect to accuracy of estimating tree heights from airborne laser scanner data. On the other hand, the proposed DTM extraction algorithms, being mostly based on trend surface interpolation, can not retain small artifacts in the terrain (e.g., bumps, small hills and depressions). Therefore, the DTMs generated by these algorithms are only suitable for forestry applications where the primary objective is to estimate tree heights from normalized airborne laser scanner data. On the other hand, the algorithm for estimating CBH proposed in this thesis is based on the idea of moving voxel in which gaps (openings in the canopy) which act as fuel breaks are located and their height is estimated. Test results showed a slight improvement in CBH estimation accuracy over existing CBH estimation methods which are based on height percentiles in the airborne laser scanner data. However, being based on the idea of moving voxel, this algorithm has one main advantage over existing CBH estimation methods in the context of forest fire modeling: it has great potential in providing information about vertical fuel continuity. This information can be used to create vertical fuel continuity maps which can provide more realistic information on the risk of crown fires compared to CBH.

Organizational creativity – Hegemonic and alternative discourses

SUMMARY Organizational creativity – hegemonic and alternative discourses Over the course of recent developments in the societal and business environment, the concept of creativity has been brought into new arenas. The rise of ‘creative industries’ and the idea of creativity as a form of capital have attracted the interests of business and management professionals – as well as academics. As the notion of creativity has been adopted in the organization studies literature, the concept of organizational creativity has been introduced to refer to creativity that takes place in an organizational context. This doctoral thesis focuses on organizational creativity, and its purpose is to explore and problematize the hegemonic organizational creativity discourse and to provide alternative viewpoints for theorizing about creativity in organizations. Taking a discourse theory approach, this thesis, first, provides an outline of the currently predominant, i.e. hegemonic, discourse on organizational creativity, which is explored regarding themes, perspectives, methods and paradigms. Second, this thesis consists of five studies that act as illustrations of certain alternative viewpoints. Through these exemplary studies, this thesis sheds light on the limitations and taken-for-granted aspects of the hegemonic discourse and discusses what these alternative viewpoints could offer for the understanding of and theorizing for organizational creativity. This study leans on an assumption that the development of organizational creativity knowledge and the related discourse is not inevitable or progressive but rather contingent. The organizational creativity discourse has developed in a certain direction, meaning that some themes, perspectives, and methods, as well as assumptions, values, and objectives, have gained a hegemonic position over others, and are therefore often taken for granted and considered valid and relevant. The hegemonization of certain aspects, however, contributes to the marginalization of others. The thesis concludes that the hegemonic discourse on organizational creativity is based on an extensive coverage of certain themes and perspectives, such as those focusing on individual cognitive processes, motivation, or organizational climate and their relation to creativity, to name a few. The limited focus on some themes and the confinement to certain prevalent perspectives, however, results in the marginalization of other themes and perspectives. The negative, often unintended, consequences, implications, and side effects of creativity, the factors that might hinder or prevent creativity, and a deeper inquiry into the ontology and epistemology of creativity have attracted relatively marginal interest. The material embeddedness of organizational creativity, in other words, the physical organizational environment as well as the human body and its non-cognitive resources, has largely been overlooked in the hegemonic discourse, although thereare studies in this area that give reason to believe that they might prove relevant for the understanding of creativity. The hegemonic discourse is based on an individual-centered understanding of creativity which overattributes creativity to an individual and his/her cognitive capabilities, while simultaneously neglecting how, for instance, the physical environment, artifacts, social dynamics and interactions condition organizational creativity. Due to historical reasons, quantitative as well as qualitative yet functionally- oriented studies have predominated the organizational creativity discourse, although studies falling into the interpretationist paradigm have gradually become more popular. The two radical paradigms, as well as methodological and analytical approaches typical of radical research, can be considered to hold a marginal position in the field of organizational creativity. The hegemonic organizational creativity discourse has provided extensive findings related to many aspects of organizational creativity, although the con- ceptualizations and understandings of organizational creativity in the hegemonic discourse are also in many respects limited and one-sided. The hegemonic discourse is based on an assumption that creativity is desirable, good, necessary, or even obligatory, and should be encouraged and nourished. The conceptualiza- tions of creativity favor the kind of creativity which is useful, valuable and can be harnessed for productivity. The current conceptualization is limited to the type of creativity that is acceptable and fits the managerial ideology, and washes out any risky, seemingly useless, or negative aspects of creativity. It also limits the possible meanings and representations that ‘creativity’ has in the respective discourse, excluding many meanings of creativity encountered in other discourses. The excessive focus on creativity that is good, positive, productive and fits the managerial agenda while ignoring other forms and aspects of creativity, however, contributes to the dilution of the notion. Practices aimed at encouraging the kind of creativity may actually entail a risk of fostering moderate alterations rather than more radical novelty, as well as management and organizational practices which limit creative endeavors, rather than increase their likelihood. The thesis concludes that although not often given the space and attention they deserve, there are alternative conceptualizations and understandings of organizational creativity which embrace a broader notion of creativity. The inability to accommodate the ‘other’ understandings and viewpoints within the organizational creativity discourse runs a risk of misrepresenting the complex and many-sided phenomenon of creativity in organizational context.
