Version control design for multi department collaboration

Hi all,

I've just implemented my first Hyperion Planning project. As a new commer, my design seem not good for the client. 

- Requirement (Data flow): Marketing => Sales => Production (Manufacturing)

- Design: Each department data has its own version of data and use business rule to move data between versions

+ Marketing - Working version

+ Sales - Working version

+ Production - Working version

Each version is then assigned to a planning unit hierarchy for approval. 

Is there any other way to resolve this data flow between departments? 

I really need a solution so that departments can collaborate with each other (result of previous department is base data for next department. If a department didn't finish their job, then next department can't enter data) but don't know how to implement it in Hyperion. Please help. Thank you so much.
