      A   Product  Line  Architecture   (PLA)  should   remain  stable
      accommodating    evolutionary     changes    of    stakeholder’s
      requirements. Otherwise, architectural modifications may have to
      be propagated to products  of a product line, thereby increasing
      maintenance costs.  Hence, it  is important to  understand which
      techniques    better   cope    with   PLA    stability   through
      evolution. This  paper presents a comparative  study to evaluate
      the positive and negative change  impact on PLA designs based on
      components and  aspects. The objective  of the evaluation  is to
      assess when aspects and  components promote PLA stability in the
      presence  of  various types  of  change.  To  support a  broader
      analysis, we  compare the stability of the  joint application of
      components and aspects to a  PLA design against the isolated use
      of aspect-oriented,  object-oriented, and component-based design
      techniques. The results show that the combination of aspects and
      components  tends to  promote superior  PLA resilience  than the
      other PLAs in most of the circumstances.
