When the performer is involved in the task from beginning to end, what is this known as?

When a performer is involved in a task from beginning to end, this is known as a "whole task." The concept of the whole task emphasizes the importance of engaging with every aspect of the task to ensure comprehensive understanding and mastery. This approach allows the performer to see how their contributions fit into the larger picture and to develop the skills necessary to execute the task effectively.

In the context of training or performance, it also aids in cognitive and practical skill acquisition. By committing to a whole task approach, individuals grow more proficient because they experience the entire process, including planning, execution, and evaluation.

The other concepts, while relevant in different contexts, do not encapsulate the same idea. Task ownership refers to the responsibility a person feels towards a task, which may not necessarily include being involved in all phases. Task delegation involves assigning parts of a task to others, instead of engaging fully in it. Full engagement can describe a mental state of being entirely involved but does not specifically imply involvement in every step of the task itself. Thus, "whole task" is the most accurate terminology for describing involvement from start to finish.
