So far in this series, we’ve talked a lot about Blockages, code and design decisions that later need to be Changed or removed in order to continue to make progress. A source of inefficiency. We’ve treated them as something that is necessarily evil, something non-beneficial. We’ve looked at them as an unwelcomed and unintentional outcome. But using them correctly and intentionally, we can leverage Blockages to our own goals. To use them as a Restriction to others, to prevent them from causing future inefficiencies. And that would be beneficial.
