Track queues by measuring queue length rather than relying on resource utilization reports. The Physics of Queueing Theory

Large batches complicate testing and deployment. If a bug appears in a massive release, finding the root cause is difficult. Small batches make it easy to isolate errors, reduce testing overhead, and simplify the deployment process. 4. Managing and Reducing Work-in-Progress (WIP) Track queues by measuring queue length rather than

Variability is inevitable, but not all variability is bad. High variability in task arrival or processing time destroys flow. Instead of trying to eliminate all variability (which is costly), Reinertsen recommends variability using buffers: time buffers (slack), capacity buffers (extra people), or inventory buffers (small WIP limits). The economically optimal buffer size balances the cost of delay against the cost of the buffer. Small batches make it easy to isolate errors,

Limiting Work-in-Progress acts as a circuit breaker for chaotic and overloaded development systems.It forces teams to focus on finishing active tasks before starting new initiatives. The Fallacy of Multitasking High variability in task arrival or processing time
