Why does the company L'Oreal Paris lie in between being an innovation mall and innovation community in different parts of their company? STATE REASONS & SOURCES please

Please use this information to formulate the question: An innovation mall is hierarchical but open: Anyone can post a problem or propose solutions in it, but the company posting the problem chooses the solution. An innovation community is open and decentralized: Anyone can propose problems, offer solutions, and decide which ideas to use.
