1. Planning Poker: All participants use numbered playing cards and estimate the items. Voting is done anonymous and discussion is raised when there are large differences. Voting is repeated till the whole team reached consensus about the accurate estimation. Planning poker works well when you have to estimate a relative small number of items (max 10) in a small team (5-8 people). Tip: try to keep the voting between affordable numbers. Maximize the highest card to 13 points. <a href="https://www.mountaingoatsoftware.com/agile/planning-poker">More on planning poker via this link. </a>2.
