Production planning and control play an important role in the stabilization of the workflow. However, in several Brazilian companies the production management staff does not get properly involved in the careful analysis of the tasks that need to be planned. This may cause discontinuities in production. One way of avoiding this problem is the implementation of activities that facilitate the work, i.e. those that prevent or minimize stoppages or interruptions throughout the production process. The aim of this paper was to propose activities that facilitate work in order to avoid workflow interruptions caused by making-do waste. This investigation was based on a case study on the planning and control process of a refurbishment project in the passenger terminal of an international airport. The main sources of evidence were: analysis of documents, analysis of project data, direct observations, and development of process maps. One of the main results was the categorization of the activities that facilitate work in terms of reduction of waste. The main categories identified were: Space Conflict, Work preparation, Sequencing, Access and Design
Process, waste, workflow, interruption, activities that facilitate the work, constraint analysis, lean construction.
