How to ensure multiple approvals of CAB , to move to next stage

Hi 

We have the requirement of multiple persons approval in Roles viz . CAB i.e. unless all the persons mapped in CAB give their recommendation as YES , the workflow should not be able to move forward , even by Change Manager

How we can make it possible
