RPB : Tour & Travel

My recent job at the office now are: How to make Tour & Travel unit owned by the company could “linked” with the company?

I’ll explain it : This unit was built a year ago with separated management form the company. After a year operation, the unit already work. It has improved asset, more employee, more services, etc which manage by itself. And The financial also separated from the companies financial. And at a closer look, we knew that the accounting system also not “qualified” yet. So, my job are to create a system that support this unit and “link” the unit to company, at least from the financial side.

The 1st plan is to redesign the Business Process and make a standard accounting for the company. But I still looking for alternative of methode to solve the problem in the best way. While I do the Business Process Reengineering, any suggestion?
