Product Portfolio by Price Segment 

After understanding your products and target customers, you can break down product portfolios at multiple price segments and meet the needs of different people and scenarios. Never focus just on one price segment - try to lay out products in multiple price segments.

Product Portfolio by Customer Segmentation

By using consumer profiles, you can launch different product portfolios for corresponding customer segments. For each product, you can identify groups of people with completely different characteristics who are interested in it.
