Heuristic Evaluation of Each Other's Implementations

As we were instructed before, we had to evaluate our batch's selected group. They have chosen a social network mobile application called "Nimbuzz" and what we had to do was to examine their implemented application and find out what are the possible breakdowns of the system.

We have identified 5 breakdowns after analyzing the system. The hueristic evaluation of Nimbuzz mobile application is shown below.
