What is one negative result of workgroups having their own independent IS$?$

Group of answer choices

They may establish an inter$-$enterprise ERP without corporate approval, interfering with EAI initiatives

They tend to end up with information and data that is isolated in that specific workgroup, resulting in information assets being isolated in many different places all over the company

They are mutually incompatible with any type of CRM software

They each use the main company IS$,$ risking overloading it
