Creating efficient, accurate, software estimations
summary
Panel argues that reliable estimates come from specifics not slogans: teams use Monte Carlo simulation and historical throughput to give probabilistic forecasts like 80% probability dates, replace time-per-item with counting work items, and build explicit buffers for known interruptions (example: a two‑week manufacturing shutdown for Chinese New Year). Practical takeaways include giving ranges not single dates, distinguishing estimates from deadlines, negotiating scope to meet fixed dates, and accepting that a promised two days vs 14 days lesson is normal and fixable by better process.
