Monte Carlo forecasting is a fantastic tool. It significantly reduces the amount of time a team needs to spend on estimation, increases the accuracy of estimates, and enables continuous planning and forecasting. I have a couple of free tools that provide Monte Carlo forecasting capabilities. They utilize your Jira project data to generate throughput, cycle time, or velocity based Monte Carlo forecasts. You can find them on my website https://home.agilecreatives.net/tools/available-tools
