Inhouse Prod + Subcontracting + External Operation for Single Material

Hello Gurus

I have a requirement in my current project , where for a single Finish goods , we need to have all procurement options. As We can produce this inhouse also , We can send one or two operation for external processing or do the subcontracting to get the finish good after sending the raw materials..( alternate BOm , Routings are available ) ?

Pl share your thoughts abt this..

Thanks in advance
