Board-Based Collaborative Work Management Tools (BBTs), such as Trello or Planner, are cooperative information systems that are widely used to support collaborative process coordination, task management, and knowledge sharing. However, designing effective boards can be challenging, particularly for non-technical users. Prior research has addressed this by identifying structural design patterns and a metamodel for board design, but the focus has primarily been on card movement as the main action shaping board usage. This paper extends that work by analyzing the role that card and list creation and termination plays in BBTs. Based on this analysis, we contribute (1) a set of creation and termination patterns reflecting common usage behaviors, and (2) an extension to the existing metamodel accounting these actions. These contributions support the design of more effective and adaptable boards and provide a richer understanding of how boards are used in practice.
