In this article conclusions from nearly 10 years of collaboration with Polish and German Engineer-to-Order (ETO) small and medium-sized enterprises (SMEs) from mechanical sector was presented. Research objective was to highlight common organizational problems they are dealing with, which prevent them from transition to Mass Customizers. As a result, a concept of 5 foundations for robust process design was proposed: procedures, product selection, machining philosophy, planning and storage, cross-functional teams. More practical solutions from this field have to be published to fill the research gap.

In this paper the method of improving production control in engineer to order [ETO] small and medium sized enterprises is presented. Briefly, the strategy of Mass Customization [MC] and a concept of the hybrid MC-ETO production system are demonstrated. Thereafter, a method of choosing components for small batch manu-facturing in advance, under conditions of single unit ETO production system, with application of fuzzy logic is described. This approach can be used in ETO companies during their transition into the hybrid MC-ETO production systems. The research was done in a collaboration with experts from the real ETO pro-duction system, in Polish SME, which manufactures mechanical parts.

This article presents the results of research conducted within a medium-sized company specializing in designing and producing mechanical appliances upon request. The authors investigated potential manufacturing costs savings per-unit, obtained as a result of changing production strategy from single unit to micro batch production. The research was inspired by concept of product modularity in terms of Mass Customization strategy. Since products redesigning along with this concept, under conditions of engineer-to-order companies is a difficult and time consuming process, the authors purpose was to highlight its potential manufacturing benefits in real production system. This research gave universal benchmark for engineer-to-order companies, hesitating whether to begin transition to mass customizer. While supervising the production system, a series of experiments has been carried out in order to analyze time reduction of production cycle for per-unit manufacturing of mechanical parts in single unit production and micro batch of three pieces.

Support of planning heat treatment processes in small batch production is very complex. In the analysed case, the bottlenecks of the processes were located on heat treatment. The difficulty in planning is due to necessity of adapting available resources to changing demand requirements. In the conditions of unit production crucial role plays changeovers time, availability of resources and cost of processing. Due to NP- difficult nature of optimization a simplified method was used. It was a complex of theory of constraints and dynamic task grouping. This is one of the attempts to solve the supporting process production problem with a method enabling its practical use.
