Defining CS Work Centers - HR module is not in scope.

Question

Hi Guys,
My client is not using HR module so Technician's personal number assignment to work center is not possible.
So what I have suggested as a work around solution is to create work center with the Technicians Name in the work center description field itself so they know by work center's description which technician is being assigned to a service order.
Say for example Work Center = ZPTech1 = Allan Miller. What do you guy's think of this solution?
Another issue is the client have one service department and this department provides different types of services. For example Inhouse repair, Onsite Service etc.
So they have teams of technicians. One team for Inhouse Repair and another team of technicians for Onsite services. However, there are cases where the technician who belongs to Inhouse repair can also sometimes perform onsite service.
So, since HR module is not in scope and technician's personnel numbers cannot be used to assign to work centers... hence my suggestion was to create work centers as technicians using their names in description field.
However, the problem comes when defining hierarchy.
Say If I create one main work center ZServ = Service Department
Then under ZPServ, if I create two team work centers as Team1 (for Inhouse Repair Team) and Team2 (Onsite Service Team). Then I assign 3 technician work centers viz., TechA, TechB and TechC to team work center Team1 and work centers TechD, TechE and TechF to Team work center Team2 using heirarchy relationship. I think so far it will be fine.
However, say TechA works both in Inhouse repairs and also in Onsite Service. Then I need to assign this technician under both team work centers Team1 and Team2 right? But as far as I know, you cannot have two superior work centers for a particular work center.
So, in this case, what is the best solution?
Instead of creating team workcenters as Team1 and Team2, shall I just create one main work center for Service Department as ZServ then create individual workcenters for each technician? without having a heirarchy structure?
Or say for example if Team1 has cost center 1000 and team2 has cost center 2000, then shall I create two workcenters for the same technician TechA with description as TechA-1000 and TechA-2000. (Then if I have two different workcenters for same technician, with his name and costcenter in the description field then i can assign each workcenter under team1 and team2.
Sorry for the lengthy message... However, I needed to explain the scenario and limitations properly in order to give you a full picture so as to get correct and best suggestions and advice.
Thank you very much for your time and I would really appreciate your inputs.
Best regards,
AR

Hi Suresh,
Answer to first part of your question is: Yes, we are considering employees as vendors and configuring it under Employees (ZEMP) Vendor Account Group.
As you have suggested about Internal Order for employees, somebody else had suggested me with the same.
But I was not convinced why I should go ahead and define internal order for each employees under the Internal Order Type: Employees.
Now could you help me in understanding as to why Internal Orders for each employee, I mean could you tell me the logic behind this, so that I would be in a position to answer if someone asks me.
If there is anymore information / documentation, could you plz forward the same to my mail id, which is: [email protected]
Thank you for your time in replying.
