In software we use the concept of Service Level Objectives (SLOs) to enable us to keep track of our system versus our goals, often shown in a dashboard – like below –, to help us to reach an objective or provide an excellent service for users.

Picture taken by Adrian March 17, 2020 A resilient system continues to operate successfully in the presence of failures. There are many possible failure modes, and each exercises a different aspect of resilience. Hence, one way to reduce risk is to make systems more observable. The first technique is the most generally useful.

Of course, we can get consumed by that exercise as well. Again, that’s not easy, but a key approach is to focus on identifying “influence points” – those locations that exist in all complex adaptive systems that have a disproportionate impact on the evolution of the broader system.

And asserted conditions only evaluated if they’re enabled, so any side effects won’t happen when they’re not enabled; they might sometimes perform local side effects, such as to do logging or allocate memory, but the program should never rely on them happening or not happening. Assertions are only about finding bugs, not doing program work.

Management textbooks dating at least as far back as the 1980s included stories of employees performing tasks the reasons for which they didn't really understand. For example, ghost code - code that is not commented out but will conditionally never be executed - is likely to be confused for real code in a reverse-engineering exercise.
