Planning poker

As explained in Lead Developer Career Guide

A collaborative estimation technique in which team members independently select numerical cards and discuss differences to reach a consensus estimate.

Planning poker is a collaborative story-point estimation technique. Team members independently choose numbered cards for a task, reveal their estimates, discuss differences, and work toward a consensus estimate. section 7.2.2

Use planning poker when the team needs to compare effort rather than predict exact duration:

  • Estimate complexity, uncertainty, and risk through relative story points. section 7.2.2
  • Discuss differing estimates because team members may understand the required effort differently. section 7.2.2
  • Choose it alongside alternatives such as T-shirt sizing or the Fibonacci sequence, depending on team fit. section 7.2.2

Search-feature estimates

A search feature can be divided into tasks such as creating an empty page framework, displaying filters, displaying results, implementing standard search, and implementing search filters; these receive progressively larger story-point estimates as effort increases.

How Lead Developer Career Guide covers it

How deep it goes
Defines cards, differing opinions, and consensus but does not detail facilitation steps or a complete session procedure.
Examples
Uses numbered estimation cards and a search feature whose tasks receive progressively larger story-point values.
What it assumes
Assumes familiarity with tasks and agile project estimation while introducing story points and alternative estimation methods.
What you can do after
Apply it to estimate relative effort collaboratively and revise estimates as project understanding changes.
How it connects
Connects story points with T-shirt sizing, the Fibonacci sequence, agile project management, complexity, uncertainty, and risk.
