Abstract
This paper gives an overview of the product development process applied to development of code-marking equipment for logs. The leaning and decision making process During the development is showed. Also the situations when a decision had to be made without having sufficient amount of information are described. The development of a log code-marking equipment for a log sorting station in a sawmill is described retrospectively. but the development of a code-marker for harvester mounting is described as in real lime. In the latter case the conditions for code-marking on-board forest machines are discussed and different possible solutions are described and evaluated but the final decision is left open. So it is possible for every reader to make his own decision. This product development process shows that in a specific case it is not only difficult to generate good concepts, it is also difficult to decide, evaluate and guess whether the concept is viable, would it work in a real environment and is it robust enough? This question appears especially when the product will be created in the field where no solution exists. Finally it is concluded that in this product development process the discovery of new ideas in concept generation is strongly motivated by the need for them, when it is realised that the available concepts/solutions do not work, then there exists much stronger motivation for finding new concepts. This is an iterative process, with several loops.
