The Jargon File (version 4.4.7, 29 Dec 2003):

manularity
 /man`yoo?la'ri?tee/, n.

    [prob. fr. techspeak manual + granularity] A notional measure of the manual
    labor required for some task, particularly one of the sort that automation
    is supposed to eliminate. ?Composing English on paper has much higher
    manularity than using a text editor, especially in the revising stage.?
    Hackers tend to consider manularity a symptom of primitive methods; in
    fact, a true hacker confronted with an apparent requirement to do a
    computing task by hand will inevitably seize the opportunity to build
    another tool (see toolsmith).
