How to control users permission settings assign to work.com in Salesforce?

Hello Shariq,

A profile contains user permissions and access settings that control what Users can do within their Organization.
Profile controls
There are two types of system permissions in a profile, Administrative and General.
You can create a Custom Profile or a Permission Set if you have either Enterprise or Performance Edition to give access.
In Contract Manager, Group, and Professional Editions you have 6 Standard Profiles that cannot be customized by default. but permissions can be added.

Hello Shariq,

I suggest, use a permission set. Permission is a collection of settings and permissions that give users access to various tools and functions. Permission sets extend users' functional access without changing their profiles. Enable Work.com features by first creating permission sets that enable Work.com object permissions and tab visibility. Once created, assign the permission sets to users with access to Work.com.

For example, to give users access to an object, create a permission set, enable the required permissions for that object, and then assign the permission set to those users. The user's profile does not change. You may want to have Work.com on Salesforce users with varying levels of permissions. While users can have only one profile, they can have multiple permission sets.
