Key Messages
• Don't be afraid of the technology debt
• Science and engineering are different. The biggest difference in
terms of cost (time) Since we are engineers, it is our mission to find
the most efficient way within the limits given.
• In reality, there is no video game product without tech debt (if not
an indie game or college project). It is meaningless to blame the
debt, it's good to think about how to manage it with ownership.
• Ownership is the key element for managing the balance
• If you look only at the task given to you, you won't see the
opportunity to improve.
• Expectation: not just bringing out issues but driving opportunities
