You should make every attempt to remediate against the identified hindering forces for change which could be the simple result of:<br><br>1. The decision maker(s) perception through experience wasn\u2019t positive. <br>2. Company culture is adverse to agile change.<br>3. IT Operations is required to retain more \u201ccontrol\u201d when consuming cloud based I\/PaaS services to better derisk outages.<br>3. Cloud security policies and frameworks have not been approved to enable new types of technologies like SC to be on-boarded and accepted by Enterprise\/Cloud\/Security Architects.<br>4.
