Let’s calculate your performance, bro!
Focus factor = 0.7 [ideal] * (1 –
OrgWaste) * (1 – ProcWaste) *
(1 – TeamWaste) * (1 – TechWaste)
For some large teams in ineffective
organizations actual FF ~ 0.1-0.2 for
ALL TEAM MEMBERS

Summary
• Focus on waste analysis instead of performance tuning
• Start from waste with maximal impact
• Don’t add waste continuously through your process
• Monitor waste level with right metrics
• Adopt focus factor based capacity planning
• Use product increment as the only performance metric
