    I did some analysis on a task.  Another ergonomist had measured someone doing the task with a NIOSH Lifting Index of >8 at the lift destination.  He was evaluating a novice, but when I evaluated a more-experienced person, the LI fell to a 3.  The novice reached further and twisted more. 

    This is always a problem in the field – are we evaluating the job or the person? It can be difficult to distinguish between the two. 

    Fun to think about these problems!

    I’d say, in general, with novice, inexperienced workers, you are more likely to be evaluating the task. While, with the experienced worker, you are more likely to be evaluating the worker. Like all generalizations this has to be tempered with judgement since as soon as you state a generalization every case seems to be an exception.
