The document discusses knowledge perspectives in systems engineering. It describes how most systems engineering knowledge is tacit rather than explicit, residing in people rather than processes or artifacts. It advocates that systems engineers act as knowledge brokers, creating "learning spaces" called "Bas" to facilitate knowledge sharing and flow. Effective systems engineers learn by interacting with stakeholders through informal discussions and experiences, rather than solely through formal documentation and processes. They internalize knowledge to build intuition and help integrate systems.
