Product Portfolio Management—Governance for Commercial and Technical Portfolios over Life Cycle  [PDF]
Arto Tolonen, Janne Harkonen, Harri Haapasalo
Technology and Investment (TI) , 2014, DOI: 10.4236/ti.2014.54016
Abstract: Companies face an important question on whether they should allow product portfolio renewal to occur without interference by merely adding new products, or should the renewal be governed based on strategic and financial targets over life cycle? New product development phase is well covered in the product portfolio management (PPM) context, but later product life cycle phases are not covered well in this context. Neither are the different product structure levels adequately taken into account, instead the current PPM only discusses the “product” in general terms. Based on analysing the portfolio related practical challenges in ten case companies, and realising the deficiencies of current PPM theory motivated this explorative multiple case study. The principal results of this study involve revealing the need for a new potential PPM governance model that enables managing commercial and technical product portfolios over life cycle phases. A governance model framework, based on horizontal and vertical portfolios managed by two centralised teams, is proposed. Based on the data, and views of industrial experts, the created new PPM governance model has potential to aid business managers in understanding PPM as an entity that has a role in managing existing product portfolios and their renewal based on commercial and technical portfolios over life cycle as collaboration between business and engineering teams in all organisational levels.
Successful Performance Measurement in SMEs through Personnel Participation  [PDF]
Janne Sinisammal, Pekka Belt, Janne Harkonen, Matti Mottonen, Seppo Vayrynen
American Journal of Industrial and Business Management (AJIBM) , 2012, DOI: 10.4236/ajibm.2012.22005
Abstract: Balanced scorecard has proven to be a functional tool for large companies, however, small- and medium-sized enter-prises (SME) have experienced it too complicated for their purposes. The aim of this research is to analyse the potential of simplifying balanced scorecard in order to acknowledge the practical realities of SMEs. The results of this study in-dicate that the viewpoints covered by balanced scorecard can be simplified into three categories of productivity, work fluency, and safety. A simplified balanced scorecard can act as a tool for internal communication in SMEs, by converting company strategy into common terms understandable by the employees. The managers of SMEs can use the results of this study as an example when considering the implementation of their business strategy. It is vital to involve employees when developing performance indicators.
Combining Steel and Chemical Production to Reduce CO2 Emissions  [PDF]
Jouko Arvola, Janne Harkonen, Matti Mottonen, Harri Haapasalo, Pekka Tervonen
Low Carbon Economy (LCE) , 2011, DOI: 10.4236/lce.2011.23015
Abstract: New legislation and emissions trading increase pressures for the industry to find new environmentally sound solutions. This research analyses the utilisation of carbon monoxide (CO), formed in steel mills from the emissions reduction viewpoint. The research studies possibilities of combining steel and chemical productions from economic and environmental perspectives. The analysis includes considering emissions costs and electricity price, when CO is converted into chemical products. The results prove the economic profitability of a steel mill selling CO gas to a chemical producer instead of using it for energy production, while CO2 emissions are simultaneously reduced.
Improving High-Tech Product Development through Communication Audits  [PDF]
Mirja Vaananen, Pekka Belt, Janne Harkonen, Matti Mottonen
Technology and Investment (TI) , 2012, DOI: 10.4236/ti.2012.31004
Abstract: Functional communication is a necessity to succeed in high technology product development where projects typically are multi-site, multi-cultural, multi-technical, and products are complex. The aim of this study is to clarify what kind of process is suitable for assessing the effectiveness of communication in high-tech product development. Based on the literature analysis, a communication audit process is constructed and tested in five product development projects of different information and communication technology (ICT) companies. Based on test case experiences and analyses, this study proposes a streamlined communication audit process. An outcome of this paper is a streamlined communi-cation audit process that provides benefits for companies, but does not burden the organisation unnecessarily. Man-agers of high-tech companies can utilise the developed process for enhancing communication in their product devel-opment.
Benefits of DfX in Requirements Engineering  [PDF]
Jari Lehto, Janne Harkonen, Harri Haapasalo, Pekka Belt, Matti Mottonen, Pasi Kuvaja
Technology and Investment (TI) , 2011, DOI: 10.4236/ti.2011.21004
Abstract: Information and communications technology (ICT) companies have realised how acknowledging the needs of both internal and external customers is a necessity for successful requirements engineering. Design for X (DfX) is a potential management approach for coordinating & communicating requirements emerging from both internal functions and external supply chain partners. This article studies the potential of DfX for improved requirements engineering. Qualitative interviews are utilised to analyse how different organisations implement the concept, including designers’ actual work, methods & tools, and organisational aspects. The results include viewing DfX as means to achieve relevant competitive goals, and describing how different companies organise these activities, together with their benefits for modern ICT companies. This study highlights how the DfX concept can be used to manage, prioritise and to better communicate
Manufacturing Process Capability and Specification Limits
Matti Mottonen, Pekka Belt, Janne Harkonen, Harri Haapasalo and Pekka Kess A
The Open Industrial & Manufacturing Engineering Journal , 2008, DOI: 10.2174/1874152500801010029]
Abstract: In modern electronics, specifications for products have constantly been tightened due to performance competition. The processes for product development and manufacturing have been developed to meet the tighter specifications and quality requirements. The development of test methods and measurement devices have not been as fast, and as a consequence, the relative impact of measurement errors has increased. Traditionally, the measurement inaccuracies have been compensated by tightening the acceptance limits. This study concentrates on analysing, through simulation, how companies should minimise the failure costs by adjusting acceptance limits. The study shows, in contrast to the conventional thinking, that widening the acceptance limits makes business sense in some cases.
Jump probabilities in the non-Markovian quantum jump method
Kari Harkonen
Mathematics , 2010, DOI: 10.1088/1751-8113/43/6/065302
Abstract: The dynamics of a non-Markovian open quantum system described by a general time-local master equation is studied. The propagation of the density operator is constructed in terms of two processes: (i) deterministic evolution and (ii) evolution of a probability density functional in the projective Hilbert space. The analysis provides a derivation for the jump probabilities used in the recently developed non-Markovian quantum jump (NMQJ) method (Piilo et al 2008 Phys. Rev. Lett. 100 180402).
Dicke model and environment-induced entanglement in ion-cavity QED
K. Harkonen,F. Plastina,S. Maniscalco
Physics , 2009, DOI: 10.1103/PhysRevA.80.033841
Abstract: We investigate realistic experimental conditions under which the collective Dicke model can be implemented in ion-cavity QED context. We show how ideal subradiance and superradiance can be observed and we propose an experiment to generate entanglement exploiting the existence of the subradiant state. We explore the conditions to achieve optimal entanglement generation and we show that they are reachable with current experimental technology.

Abstract: Sonja W lte analysiert, wie Frauenbewegungen in Kenia auf lokaler und auf nationaler Ebene agieren. Im Mittelpunkt der feministisch-politologischen Arbeit steht die Umsetzung der universellen Menschenrechte am Beispiel internationaler Abkommen zu Frauen- und Menschenrechten. Der lange Weg vom Zustandekommen internationaler Konventionen, deren Ratifizierung durch die kenianische Regierung, vor allem aber die Implementierung in die nationale Gesetzgebung und die Umsetzung in lokale und allt gliche Lebensweisen werden ausführlich dargestellt. Den untersuchten kenianischen Frauenbewegungen kommt dabei im Kampf auf der rechtlichen Ebene sowie bei der Durchführung von politischen Bildungsseminaren und Aufkl rungsangeboten eine besondere Bedeutung zu. Sonja W lte analyzes how women’s movements in Kenya act at the local and the national levels. Central to the feminist-oriented study is the reference to universal human rights as well as the international treaty on women’s and human rights. The study details the long journey from the formation of international conventions, to their ratification by the Kenyan government, and in particular to their implementation in the national laws and the implementation in local and daily lives. Those Kenyan women’s movements examined here are marked in particular by their struggles at the legal level as well as their execution of educational political seminars and explanatory efforts at the community level.
