Scrum – the bad nasty
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

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

Scrum – the good
1. Focus on DONE: iterative 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: simplicity and freedom
• 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: heavily underestimated
• Short iterations with sprint reviews and retrospectives fix things
• Self-managing and self-organizing teams focus on improvement

Scrum – the Brilliant
September 13, 2017 22
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?
