The main page asserts that "The TCG establishes best practices for inviting community involvement in the product development and deployment cycle." So it's important to get them right. Let me quote
The Wikimedia Foundation designs and develops software as part of its mission to provide the essential infrastructure and an organizational framework for the wiki projects. This development must be collaborative and receptive to feedback throughout the life cycle of a product.

I suggest expanding the first statement to
The Wikimedia Foundation works with the wider communities to design and develop software as part of its mission ...
and the second to
Foundation Product teams should collaborate and share information with the communities about software features considered
