Data Driven
planning in Kanban
Arkadiusz Felinczak
ALI - Lightning Talk Smackdown!
Planning – why not estimates?
• Estimates are opinions.
• Hofstadter’s law.
• Parkinson’s law.
• Anchoring effect.
• Estimate = commitment.
Lean approach - measure
 Measure CT and throughput.
 Don’t mix different work types.
 Break the work into similar size items.
 Visualize and control your metrics.
 Improve.
Cycle Time and WIP
 Measure your team Cycle Time.
 Make sure that WIP is constant (Little's law).
 Provide transparency on metrics to team and stakeholders.
 Use numbers for communication.
Introduce Work Item types
 What are typical types of work team
does ?
 Diffrent size, complexity, treatment,
required skills, process, ...
 Measure values and set Service
Level Expectation.
Source: https://www.engage3.com/dynamic-solutions/
Don’t focus on average CT
 Most teams starts with average Cycle Time.
 What is average of 5 and 20 ? Is it useful ?
 Use 85th Percentile for SLE.
 Use control charts to visualize metric.
Ageing – leading indicator
 Put dot on a card during
standup (or SOS).
 Mark dots red if card
seems to take long.
 Discuss during standup
and swarm if needed.
Cycle Time Control chart
Metric should be stable to replace estimates!
Summary
 Stable metrics can replace estimations.
 They are easy to collect.
 It is harder to argue with numbers.
 No negative impact on productivity.
 Transparent metrics reduce need for status reports.
Thank you
