I wrote an article for BNet on Mass Customization!
It includes five things you should consider before setting up shop:
1) Have you defined your solution space?
I’d like to credit Prof. Piller at this place btw - somehow quoting an academic is a complicated thing.
2) Will you have your own production facility or outsource?
3) Do you know the appropriate price levels for your product?
4) Have you explored alternative ways to market your product?
5) Do you have a plan for scaling the business?
Enjoy the article!
