Hi Team,
I am planning to show a BIBD design for a Marketing professor. I found this example.
Factor A: Placement of promotional displays (A1: Front of store, A2: Middle of store, A3: Back of store).
Factor B: Type of promotion (B1: BOGO, B2: Discount, B3: Free gift).
Factor C: Timing of promotion (C1: Morning, C2: Afternoon, C3: Evening).
Resulting Design to be created to run across 5 stores

How can i create this using BIBD? (Or is there a way to recreate this using Custom Design?
thanks in advance
