I Went to the Lean Software and Systems Conference in Atlanta and All I Got Was a Bunch of Thought-Provoking Ideas * Ted M. Young Development Manager, BillingCenter [email_address] Guidewire Software ( http://www.guidewire.com ) *And a cool t-shirt

A Lean Background System Thinking Inventory = Risk Just-in-Time Delays Cause Waste (Batching)
Some Terms MMF/MVF Minimal Marketable Feature Minimal Viable Feature WIP Work-in-progress Kanban  看板  Sign board
Lean Focus Value > Flow > Waste
Four Big Ideas Small Slices are Best Make Work Visible WIP Limits and Flow Lean = Whole System
Small Slices are Best Estimates are waste
Make Work Visible
Make Work Visible Can't improve what you can't see Exposes knowledge Makes implicit -> explicit Metrics provide Guidance What's right? What's wrong?
Measurements Lead Time Request to Delivery Cycle Time Work Begins to Work Ready to Deliver Throughput Little's Law for Queuing Theory
Theory of Constraints Cause of Delays Long feedback cycle Building unnecessary features  Overbuilding features Result of Delays Finding bugs gets harder
Queue & WIP Limits
Queue & WIP Limits Limit Queue Size Forces Bottlenecks Upstream
Goal: Single-Piece Flow Work ONE thing to completion "Swarming"
What about Iterations? Artificial boundary? How about Feature-based (MFV)?
Support/Service Provider Multiple Classes of Service (QoS) Normal Expedited
Lean = Whole System Allocate capacity strategically Delivering Value to Customers Solving Problems Sustainability Support Optimize for the Whole System More features faster doesn't mean improved sales
