Planning Tools

Calculate expected waiting time in queues using queueing theory (M/M/1 model). Estimate wait times based on arrival rate, service rate, and number of servers.

Turn optimistic estimates into realistic deadlines using planning-fallacy buffers, interruption frequency, and your historical estimation accuracy.

Estimate the productivity cost of keeping open loops in your head. Quantify cognitive overhead, mental RAM load, and time reclaimed by externalizing tasks.
