* Usefulness depends on the researchers' ability to collect a sufficient set of product attributes.  If important attributes are excluded or neglected, the value of the procedure is reduced.
* If sets of observed variables are highly similar to each other and distinct from other items, factor analysis will assign a single factor to them.  This may obscure factors that represent more interesting relationships. {{Clarify|date=May 2012}}
* Naming factors may require knowledge of theory because seemingly dissimilar attributes can correlate strongly for unknown reasons.
