Requirements for developing production planning and control systems for engineer-to-order industrialized building systems

Several efforts for industrializing construction have been made in different countries, and there has been a growing demand for engineer-to-order (ETO) industrialized building systems. In this context, products are unique for specific clients, as customer orders are placed at the design stage. There are many challenges for planning and controlling those building systems, due to the high level of complexity involved. The aim of this research is to propose a set of core requirements for production planning and control systems in ETO industrialized building systems. The methodological approach adopted in this investigation was design science research. It was based on a literature review on different planning and control models, and also on an empirical study carried out in a steel fabricator company. The proposed set of requirements is aligned with the management-as-organizing approach, challenging some traditional project management assumptions, including the use of metrics and practices that are not suitable for the high degree of complexity that exists in ETO environments. As a practical contribution, the requirements can be used by ETO construction supplier companies to support the conception and development of planning and control systems.
