We surveyed 736 IS professionals in organizations at varying levels of the Capability Maturity Model (CMM) to investigate job attitudes and perceptions. Although anecdotal reports and the scant preliminary empirical studies to-date suggest job attitudes and perceptions improve for employees as organizations climb the CMM ladder, we found evidence of a more complex picture. IS workers reported significantly lower professional efficacy and affective commitment in organizations at CMM Level 3 than in organizations at Level 1, and reports of cynicism were higher in organizations at upper levels of the CMM.
