Conchango | Buy Agile Planning Poker Cards.
Used these for a planning meeting today…they were actually quite useful for understanding different team members’ estimates on development times and their reasonings behind the card they chose to play (which represented the estimate they chose), then resolving timeline discrepencies in a less tense manner between members as we worked them out.
I recommend anyone with project managers to deal with to bring a few of these to your next planning meeting and try the strategy out yourself, it definitely would have been one (fun) strategy to deal with project managers of my past who held me to crunching deadlines set for me where I felt my input was unheard in setting.
