THE CCP has been highly selective about the kinds of people it recruits, although the criteria for membership has changed over time. The qualities of the party's key personnel and rank-and-file membership as well as the integrity of the party's organization have been key elements of elite strategies for successful policy implementation, regardless of the content of their policy agenda. As is the case for most complex organizations, the criteria for membership has changed along with the party's main goals. For example, different types of skills were needed during the Great Leap Forward than are sought today when the party is pursuing “reform and opening” (gaige kaifang) policies. Mass mobilization and propaganda skills are appropriate for one set of policy goals, but technical expertise and entrepreneurship are necessary for others.
