What is the term for a sequence of activities that must be consecutive due to crew or equipment availability?

The term referring to a sequence of activities that must be consecutive due to crew or equipment availability is best described as restraints. This concept highlights the limitations imposed on scheduling and resource allocation, as certain activities can only proceed one after another based on the availability of the necessary resources.

Dependencies typically refer to the relationship between tasks, indicating which tasks must be completed before others can start, but do not specifically address the need for consecutive activity based on availability. Constraints generally refer to broader limitations that might be imposed on a project, including time, resources, or budget, but do not focus solely on the sequence dictated by crew or equipment issues. Conditions might imply external requirements or circumstances that could affect activities but do not specifically signal resource-driven sequencing.

Thus, restraints explicitly capture the nature of the situation where activities must be performed in a specific order due to the limited availability of crews or equipment.
