The purpose of this study is to explore the engagement in an innovation ecosystem for knowledge co-creation. It aims at exploring the various aspects of ecosystems, innovation, and knowledge which can drive or hinder actors to engage in collaboration in an innovation ecosystem. A single case study was selected as a research strategy (The OSMaaS project), as it provided us the opportunity to analyze an innovation ecosystem with specific characteristics that few has considered before. Semi-structured interview was used as data collectiontechnique since this interview method offered us the required flexibility to explore in depth theindividual experiences lived during the process of evaluating whether to engage or not to the OSMaaS project. Consequently, a hybrid approach of thematic analysis was selected as methodfor data analysis as it allowed us to interact with the interviewees or the empirical world, theconcepts regarding innovation and ecosystems or theory, and the OSMaaS project or the case study. The findings show that aspects of ecosystems, innovation and Knowledge co-creation aspects such as co-opetition, ecosystem governance and structure, proximity, relative advantage, compatibility, complexity, trialability, observability, competitive advantage, and product development contain factors driving and hindering actors’ engagement in aninnovation ecosystem. These factors are explained within this study and show what have droveand hindered actors to engage in the OSMaaS project.

This thesis deals with the innovation of information system (IS) as a decision problem. The main objective of this thesis is the construction and the application of a method to select an optimal innovation variant of IS in an organisation of any scale. The designed method is based on the conception of the innovation of IS in the methodology "Multidimensional Management and Development of Information System (MMDIS)". The proposed selection method (Method of Innovation Modules based on MMDIS - MIM) is intended to serve mainly for decision-making on a strategic level. The IS structure is mapped in accordance with the MMDIS methodology. Innovation aspects are derived from two approaches: innovation aspects based on the MMDIS principles ("module of principles" - e.g. integration, flexibility, standardisation, measurability) and innovation aspects based on the IS dimensions defined in MMDIS methodology ("module of dimensions" - e.g. software, hardware, processes and functions, finances). The proposal method enforces a systematic approach to evaluation of the innovation variants, ensuring that the innovation aspects (the principles and the dimensions) are aligned with key requirements. As an example, this method is applied to an existing electronic toll system operated in the Czech Republic. Basic innovation variants of the electronic toll system are described - the microwave, the satellite and the hybrid toll system. Case studies from the Czech Republic, Austria and Germany are used for support the proposed innovation variants, as well as evaluation of variants. The principles and the dimensions form a framework for description and evaluation of the telematics, of the electronic toll and of the innovation variants of the electronic toll. The variants are compared within the framework of refined principles and dimensions, the optimal variant is proposed. The used evaluation parameters are a result of an analysis of published studies and specific toll system technical designs. The Method of Innovation Modules was constructed on the basis of MMDIS methodology and demonstrated by application in an example scenario (electronic toll). The key result of the proposed method is the comprehensive structured map of available system innovation opportunities.
