Radek Lont

Went along the way of experience from a software developer, through a team leader to a Scrum Master role. The latter played for development teams, as a change agent inside own organizations or as a consultant advising others. Knowledge and experience gained first in huge telecommunications projects (mainly for Ericsson), enhanced next in Seamless – changing the world of payments with SEQR startup. Founder of Zwinna Lodz (Agile Lodz) – local community expanding agile/lean outside the IT. Currently self-employed working with different organizations on their way to change.

The wisdom of crowds—an aspect of sprints you count on

ScrumMasters insist on having the whole teams at plannings and other Scrum events. When team asks why first answer is that The Scrum Guide says so. But why? Well..cause it's reasonable?
In 2014 and 15 I made a series of experiments about the wisdom of crowds in different groups (more than 100 people all together) trying to verify the Fransic Galton's discovery from the beginning of XX century (the crowd at a county fair accurately guessed the weight of an ox when their individual guesses were averaged). I added an aspect of diversity in possibilities of comparison during estimation to conclude for the Scrum teams about refinement process, plannings and daily meetings.
I would like to share it all with You now and do the experiment at our meeting too.
