Abstract. Engineer-to-order products are customized to a particular client's specification. Planning can be a problem as the products may be large and complex especially due to uncertainties in the duration of the operations. A conceptual project manufacturing planning and control (PMPC) framework is presented in relation to typical engineer to order (ETO) companies. The existing approaches, problems, solutions, and limitations of current manufacturing planning and control (MPC) for ETO environment are discussed. This paper contributes to the development of an improved understanding and more robust definition of MPC in ETO industries, and highlights how the key challenges and the opportunities that PMPC offer in an ETO sector.

Abstract. Researchers have recognized engineering changes affecting operations as a major obstacle to the delivery of the product in ETO environment. However, there is little academic literature addressing sources of engineering changes that affect materials management throughout the order fulfillment process in an ETO environment. The key research question addressed in this paper is how the substantive sources of engineering changes impact materials in ETO environment can be identified and categorized. Due to the nature of different supply chain configurations different engineering change situations exists within and across these companies.

Abstract. In this paper, we discuss the importance of collaborative planning for manufacturing enterprises. We have analysed user stories provided by industry to understand the collaborative processes in their workplaces and their needs for Information Systems (IS) support. Based on the analysis of the user stories, we have proposed a framework for collaborative planning and ideas for the design of IS supporting this activity. These will be used to conduct focussed interviews with the users to refine our design before implementing the system. IntroductionGlobalization has made manufacturers face increased challenges for better product quality and shorter delivery time [1]. To remain competitive in the market, organisations have to cope with pressure on prices, smaller orders, more suppliers, more governmental regulation and increasing material and energy costs. These new business drivers have made it necessary for manufacturing enterprises to collaborate with each other, their customers and suppliers to leverage each other's competences to remain competitive. This has increased the need for Information Systems (IS) support for collaborative planning across organizational borders. The behaviour, activities and all the dynamic aspects of the manufacturing enterprises highly depend on information systems and the processes, services, and data they manage [2]. Today's market is dynamic and uncertain. The products are highly customized and diverse in nature. The environment consists of repetitive (standard) and non-repetitive (customized) components and tasks. There is a high complexity in the nature of products, with short lead time, increased outsourcing and distributed teams who are trying to rapidly fulfill the needs of the customers. To effectively tackle these challenges and to obtain competitive advantage in today's internet economy, an efficient collaborative planning, information and decision support system is required.

Abstract. In this study we aim to understand how performance indicators should be designed and implemented across various phases and levels in materials management in the order fulfilment process under engineering changes. The paper address questions such as how can such systems help managers to handle and manage materials management under engineering change situations? How do we convince potential users and obtain their support when starting to develop such a system? How can we aggregate performance indicators? How do we present results? Then using the literature review and the results of the empirical study from a Norwegian company operating in ETO product delivery strategy, we develop a framework.
