IPS does not think to introduce system mainly like other vendors, we think it is important to think the services with which customers go for the future after going live.
There are many companies which do not have information system staffs but introduced SAP ERP. And there is a way that the person in charge is not dedicated but concurrent post join the project, so, you do not have worry about lack of human resourses.
If you are using same system as your parent company, it is no problem for that. However, if there are many restrictions and it does not fit your work, it will be good for you to think about original system.
