According to Naik & Tripathy (2008), the main focus of quality factors categorization is on 
expectations of software post-development activities compared with in-development activities. 
However, we think that quality factors have the same importance in both, expectations of software 
post-development activities and in-development activities. Concerning the fact that "The quality 
assurance activities must start early and become an integrated part of the entire development project" 
(Hass, 2008), we presume that quality factors are conformed in development phase and it leads to 
expectations of post-production activities as well. Conformation of quality factors are ensured by the 
following QA activities:
