  An organisation (whether it is in the private or in the public sector)knows where it is headed, it has a vision. To achieve this vision the organisation can have a strategy beforehand or the vision can be the result of a continuously improving strategy.The strategy can be developed according to the earlier routines or in a totally new way. Many times failures help to find a solution better than the chain of successes. The lessons learned should inevitably be part of the following cycles otherwise the same issues rise again and again which finally ends in exasperation and giving up. When we create a learning process it is easier to focus on avoiding the obstacles than motivation. PDCA is a well-known method for it but what prevents us from applying it the proper way? What are the obstacles that prevent the organisation from developing through its learning processes?

  What kind of electronically available content can students prefer? We conducted a questionnaire survey in which we asked about the study habits of university students: where, how, with whom, when, how much, where do they study? Do they use problem-solving software? We need to find out about it, since learning habits and strategies have changed significantly in recent years. Taking into account the answers to the questionnaire, we draw attention to some activities that improve the quality of education.

  Life cycle costs are important factors in decisions on renewable energy investments. Since maintenance costs generally constitute a high portion of the life cycle costs, the maintenance strategy applied in a project can affect the bottom line significantly. The effective maintenance tools used in the production industry (e.g., diagnostics, condition monitoring, data management, integrated information systems, machine learning, and automated decision making) can be involved in planning and maintenance of renewable energy systems to gain the benefits of these approaches. In this paper the effects of maintenance strategies on life cycle costs are investigated and the benefits of up-to-date condition monitoring techniques are presented through case studies.
