Where the term comes from
A long-standing construct in neuropsychology. Barkley's model is among the most influential frameworks for how it relates to ADHD.
Why it matters
Most task management systems demand executive function — deciding priorities, maintaining categories, remembering to review. For people whose executive function is stretched, the system itself becomes a load rather than a support.
The common mistake
Recommending more elaborate systems to people who struggle with executive function. Complexity increases the demand on the exact resource that is limited.
What it looks like in practice
