How could we implement maker and check/4 eye check in Appian

Hi, 

the approver can be the same person that have create the submission task, there aren't problem. Simply you have to make a new task in the same process that will be only "approver".

If the approver can't be the same person that have create the submission task, the simpliest way you can use is customize an interface that you'll expose tasks and remove that user.

Thanks Vicenzo.

How do I remove user from the group?

My Process has 2 steps. Submit work and someone from same group will review it.

Assume that I've group X having Mr A, Mr B and Ms C.

As Mr A subimtted the work, only Mr B or Ms C could review the work. 

Store all assignees as users in a process variable. On the first task, the task property tp!owner holds the user that submitted it. Use the difference() function to remove that user from the list of assignees.
