Rescinding offers to candidates within two weeks of their start date isn’t a good look.
There are people in an asymmetric power position on the other side of that agreement.
What is the trust-producing outcome of that behavior?
Replying to @garrettgillas
Yes. People have made (hopefully reversible) decisions based on the expectation. What macroeconomic (vs market specific) conditions have changed in the past two weeks?
And if they are _that_ volatile, then that’s also an informative future-looking datapoint.

That’s not going to cover visa issues, deferred education enrollments, relocations/lease terminations, or health care (ack - applies to early BIS as well).
I acknowledge they can, and perhaps it even makes sense they do so.
Questions I’ve found helpful:
1. How will we know it’s doing what we expect? 2. How will we know it’s doing something we didn’t expect? 3. How will we know it’s not doing something we expect? 4. How will we know it’s not doing something we didn’t expect?

Five step summary:
1. Identify the system’s constraint 2. Decide how to exploit the system’s constraint 3. Subordinate everything else to the above decisions
Replying to @mweagle
4. Elevate the system’s constraint 5. If in the previous steps, a constraint has been broken, go back to step 1. Do not allow inertia to cause a system constraint.

My other takeaways…
* Local operational maxima may be global system minima * Bottlenecks are everywhere and they move around * Make work (and pending work, inventory) visible * Variability is intrinsic, but not insurmountable * Full utilization is unattainable
Replying to @mweagle
* Measurability bias is real * Alignment on “what is the goal” is harder than it sounds

There’s a “Context Propagation and the Theory of Constraints” talk in there somewhere.
