On the far right should be what the competition provides. Along the top should be a list of the product’s capabilities meant to fulfill customer needs. In the bottom section should be the targets, the things your company must acquire for the product, long term goals, and your standing amongst the competition.

Nice summary of a broad technique which is underused. I find it especially useful for pre-project concept/feasibility work.

As far as overlaps/conflicts of customer needs – this diagram can also have a triangle on the left that allows you to plot such clashes / trade-offs if required – although this is not that common.
