  • Ranking and prioritization as regular activity and prerequisite to scaling agile Erik Schumann Erik.schumann@sellegi.se @Schumann_Erik
  • The economic system consists of interconnected variables ”We are like the drunk under the lamppost looking for his keys where the light is best, instead of where he dropped them.” Don Reinertsen, The Principles of Product Development Flow Cycle Time Product Cost Product Value Development Expense Risk
  • We focus on cycle time! Why? ”Developers measure development cycle time and seek to make it shorter. However, when you ask them how much life-cycle profit will decrease due to a week of delay they don’t know” Don Reinertsen, The Principles of Product Development Flow Cycle Time Product Cost Product Value Development Expense Risk
  • While you may ignore economics, it won’t ignore you. ”If you only quantify one thing, quantify the cost of delay” Don Reinertsen, The Principles of Product Development Flow Cycle Time Product Cost Product Value Development Expense Risk
  • Estimated Variable Parameters Restrictive Fixed Parameters Set of requirements Working featuresCost Delivery timeCost Delivery time Agile development Predictive development Agile development turns the world around
  • Prioritization: Fixed Cost of Delay and variable duration
  • Prioritization: Fastest delivery of business value with WSJF Focus on remaining duration! Do not consider money already spent.
  • Cost of Delay / WSJF according to SAFe User|Business Value + Time Criticality + RR|OE Value WSJF = Job Size SAFe Suggestion: Use the relative fibonacci scale for each variable
  • Simplified WSJF: Relative prioritization with stacked ranking High Low
  • Summary • If you only quantify one thing, quantify the cost of delay • Prioritization is based on estimates and guesses • Prioritization is a dynamic activity. Do it regularly • Prioritization can be simplified using relative, stacked ranking
