Bias, priming, and salience are the main psychological factors that influence our ability to estimate. Knowing what happens psychologically when we estimate, and using techniques from psychology, helps us to deal with those factors so that we can improve our estimations argued Joseph Pelrine, social complexity scientist and PhD researcher in psychology.
When developing a high speed printer based on a new print technology things change often; you need an effective and flexible solution for managing a large project with many different disciplines.

Product backlog refinement is a practice in which product backlog items are split and often re- estimated. This post is based on user story splitting and re-estimations.
Vasco Duarte suggests that people should experiment with #NoEstimates to learn and find ways in which it can help them to deliver value on time and under budget. He is writing a book on #NoEstimates in which he explains why estimation does not work and how you can use #NoEstimates to manage projects.

Debbie Madden and Vasco Duarte share their views on no-estimates.
This post covers the value of estimation in large and small scale projects and views on no estimation.
There are different opinions for conducting sprint planning. Long debate is happening between velocity driven sprint planning and commitment driven sprint planning. Mike Cohn, founder of Mountain Goat Software, shared his views in his recent blog on Why I Prefer Commitment-Driven Sprint Planning.
Agile teams which use noestimates, can use slicing heuristic to empirically measure cycle time to help them predict how much, can be done before doing the actual work.
Agile teams measure the velocity of their sprints. It helps them to plan and track their progress and provides insight for product owners to plan product releases. Can teams also use velocity data when they want to improve themselves? Several authors have written about velocity and shared their concerns on measuring velocity to improve the productivity of teams.
A new "Scrum Kickoff Planner" has just been released by Adam Weisbart with the aim of facilitating team discussion around the important facets of starting a new Agile team or project.
