5 The Good July 6,

7 Scrum the good 1. Focus on value and results Finishing stuff early and often drives results, gives early feedback, prevents rework and waste If things are unfinished, you are not flexible. Scrum brings agility through constant focus on finished results: DONE increments 2. Rhythm through Sprints Time-boxed short Sprints create agility, bring freedom, simplicity and predictability Sprints change to focus on work instead of moving people around 3. Self-cleaning effects Short iterations with sprint reviews and retrospectives fix things Self-managing and self-organizing teams focus on improvement

8 Traditional (u-boat) vs Empirical (dolphin) July 6,

9 CU-Later versus CU-Soon July 6,

10 The Bad July 6,

12 Scrum the bad 1. Need for super PO s Product-owner is unfairly positioned as solution for decision making Great product-ownership seems impossible for a single person 2. Dysfunction of teams Building great, skilled, competent, stable teams is really complicated Not every employee becomes happy in a team Attrition is an exponential enemy of stable teams, but is neglected 3. Seems so simple Unfair expectations regarding ease of use and simplicity Scrum is extremely hard to master requires a 180 degrees switch Scrum demands rigorous changes in governance and culture to let it really prosper -> Doing Scrum does not make you Agile

13 Agile with attrition is risky Source: Smite, Darja; Van Solingen, Rini. What's the True Hourly Cost of Offshoring? IEEE Software, 2016, 33.5: July 6,

14 The Ugly July 6,

15

16 Scrum the ugly 1. Abuse is too easy Short-term focus with quick wins now and technical debt later Pushing work to teams by product-owners from Sprint to Sprint: pressure cooker burn-out Risk for waterfall in disguise with ready-teams, detailed product backlogs and market delivery at the end 2. Deadlock between teams Hard to scale - independent end-to-end teams often unfeasible Stalls with strong dependencies between teams, but is hard to avoid 3. Hype Scrum is used as silver-bullet for everything (stickies and stand-ups) Big chances for over-processing and meeting-explosion

17 Yes, but after all these problems. July 6,

18 Scrum is being rolled out everywhere July 6,

21 Scrum - Greatness 1. Jump start for fast results that focus on value, customer and user Scrum helps to jump start delivery when the concept, culture and cadence are part of everyone s standard way of working There is no alternative for speed and agility than customer focused short-cyclic teams It is just a matter of time until Scrum is part of everyone s DNA Building great teams in split seconds?
