-    web-based applications. Your manager gives you an assignment to
-    develop a software quality model for the company. The model should
-    show external quality attributes, corresponding internal
-    attributes and metrics. Present the assumptions that you will use
-    while creating of the quality model. Provide an explanatory text
+          The internal attributes can be measured from within the
+          system (like loc etc) while for the external attributes
+          one must look at the finished product to se the external
+          attributes. Also in general internal attributes are
+          considered easier to measure (and then predict) then the
+          external attributes.
+
+          This is partly since the internal attributes can be
+          measured more ``directly'' then the external. For
+          instance loc is easy to count while usability is a lot
+          harder to measure. For the internal attributes one can
+          expect to be able to get absolute values while on the
+          external attributes one can expect them to be less
+          accurate.
+
+          However several of the internal attributes (if not all)
+          does affect the external attributes in a way that can
+          (in most cases) be predicted. One can for instance say
+          that in a specific solution if the loc is increased
+          (both with comments) then one could expect to get a
+          higher maintainability. Also most of the external
+          attributes can be affected via the internal if the
+          developers keep the external attributes in mind.
+
+          In most cases (if not always) the customer of the product
+          is more interested in the external attributes. Does this
+          mean that the external attributes are of ``greater''
+          value to the team developing the product?
+
+          Not always but in many cases. Also one should keep in
+          mind that just because the external attributes are more
+          important that the internal could be forgotten.
