Passing responsibility for task execution between user and system*1 pointTask migratabilitySubstitutivityCustomizability

It seems that you're presenting a question or concept related to user-system interaction, perhaps in the context of design or systems theory. However, to provide a meaningful response, I would need clarity on whether this is a question about definitions, implications, or something else entirely. Here's a brief explanation of each term you've mentioned:

1. Task Migratability: This refers to the ability to transfer tasks or responsibilities between users and systems seamlessly. This characteristic is crucial in multi-user environments or systems designed for collaboration.

2. Substitutivity: This concept discusses the ability to replace one task or component with another without affecting the overall system's functionality. In user-system interactions, this might involve substituting human tasks with automated processes.

3. Customizability: This is the degree to which a user can modify the system to suit their specific preferences or needs. Systems that offer high customizability enable users to interface and use the system as they find most effective.

Understanding these concepts can greatly impact system design and user experience, especially in modern computing environments where interaction plays a pivotal role. If you're looking for a specific analysis or application of these terms, please provide additional context!
