The document proposes a conceptual redesign of Blackboard to address 4 main issues: 1) Isolated users, 2) Lack of integration between features, 3) Inflexibility, and 4) Inability to keep up with developments in technology and society. The proposed redesign includes: 1) Enhancing communication and collaboration between groups/profiles, 2) Better integrating core components like communication, file sharing, and scheduling, 3) A modular design for increased flexibility and customization, and 4) A marketplace for user-generated modules to encourage innovation.
