Until recently, furniture of high quality at a low price was a contradiction. The Modos modular furniture system, which was launched at the end of 2014, has the potential to break this contradiction. By using standardized aluminium connectors and rectangular wood based boards, various types of furniture can be assembled and disassembled many times – without the any tools. Despite its great potential the Modos system has a few shortcomings, caused by the aluminium connectors. Modos is not particularly cheap, and from an environmental perspective, there is room for improvement. For this reason, the objective of this project was the development of a similar modular furniture system, which would be entirely wood based. Wood is more eco-friendly, as well as arguably cheaper and more beautiful. A secondary objective was to evaluate the benefits of lean product development principles.The main challenge from a technological viewpoint was to achieve a sufficient structural strength of the wood based connectors, without significantly compromising the design. From a project planning perspective, the critical task was to manage the free flowing process of developing an innovative and design driven product.By applying lean principles, the product development process went smoothly and could be completed within the best-case time frame. The resulting product – called ‘Notofusy’ – met all the requirements as far they could be assessed. Notofusy is stable, flexible, eco-friendly, and most likely somewhat cheaper than Modos. However, before Notofusy can be launched, some details, such as precise manufacturing costs, have to be addressed and worked out.
