Planning Poker, also known as Scrum Poker, is a consensus-based technique that not only helps agile teams to estimate the time and effort that is required to complete each initiative on their product backlog but also identifies issues before time and within the course of a user story. It makes the meeting more short, productive and creates estimates with the involvement of the whole team. It is mainly used to avoid the influence of other participants, and force each person to think independently and give their opinion.
