NOT ON THE CURRENT EDITION
This blip is not on the current edition of the Radar. If it was on one of the last few editions, it is likely that it is still relevant. If the blip is older, it might no longer be relevant and our assessment might be different today. Unfortunately, we simply don't have the bandwidth to continuously review blips from previous editions of the Radar.

优雅扩展性理论 定义了适应性系统(包括构建和操作软件的社会技术系统)的基本规则。这一理论中的一个关键概念是 能力边界(competence envelope) —— 系统在面对失败时能够 稳健 运作的边界。当系统被推到能力边界之外时,它会变得脆弱,更容易崩溃。该模型为理解系统故障提供了一个有价值的视角,例如在 2024 Canva 故障 中观察到的复杂故障。
残余性理论 是软件架构思维中最近的发展,它提供了一种方法,可以通过故意引入压力源并分析系统随时间对历史压力源的适应情况,来测试系统的能力边界。这些方法与社会技术系统中的反脆弱性、弹性和稳健性概念相一致。我们期待这些理论在实践中的应用,为提升系统的适应性与可靠性提供新的思路和工具。
