The Global vs. Local Advisor

Help me decide what to standardise globally and what to adapt locally.

My product/business: [DESCRIBE]
The markets: [DESCRIBE THE RANGE]
The pressures: [COST EFFICIENCY VS LOCAL FIT]

Provide:
1. The elements where global standardisation saves cost and builds a
   consistent brand
2. The elements where local adaptation is necessary (regulation, taste,
   language, channels)
3. The classic mistakes (over-standardising and alienating locals;
   over-adapting and losing scale)
4. A framework for deciding element by element
5. A recommendation for my situation

Find the balance between global efficiency and local effectiveness — the
core tension of international business. Say where mine should lean.
