﻿If its a 3 person team, and one person believes that the story point can be delivered in 3 weeks , then total effort should be 3 * 5 * 3 = 45 days.
However , as people are generally on leave / hoildays , so a availability factor of 0.85 can be considered .
If for another story point ,effort is believed to be of 16 days , then the card selected can be the nearest Fibonacci number or 21 ﻿.
However , the cards are not shown immediately. The moderator asks everyone whether they are ready , and then everyone shows their cards.
Generally the cards shown differ from one another , and the moderator tries for an agreement. After the agreement about the right estimate for the current story point is reached, a new story point is discussed.
