The Agile Dysfunction Spiral
Detailed sprint planning
Formal sprintcommitment
Work the sprintUnfinished work
We need to get better at
planning sprints
Coaching to helpimprove sprint planning
Sprint planningtakes longer
ManagementApplies pressure
Culture of Blame creeps back in…
Team works overtime
Are we really just after better sprints?
Cargo Cult (Agile)
Many early Agile attempts simply installed practices (recipes).
Warning!Following recipes leads to Cargo Cult Agile
Mob Programming
Mob Programming: The original MVA?
Reduces or Eliminates: 1. Standup meetings2. Detailed planning sessions3. The need for estimates4. Team alignment activities5. Context Switching6. Individual status updates7. Burn-down charts for performance tracking8. Code Reviews

status updates?
Story Points: The sacred cow of Agile
Sometimes this causes unnecessary
confusion and drama!
Story points are designed to be abstract.
Velocity is an attempt to plan work based on an abstraction, based on an estimate.

Velocity is not Minimal Viable Agile
Velocity (based on story points) has become a social and business currency.
What about Story Point predictability?

Story Point Predictability?
A product team from Microsoft shared their story point estimates. They performed three release forecasts:
1. Story Points 1,2,3 for small medium and large2. Story Points 1, 3, 5 for small medium and large3. All stories are 1 point (just count # of stories)
Story Point Predictability?
All dates within 3 weeks of each other in a 38 to 42 week project!

”At that point, I stopped thinking that estimating
was important.”

Planning in the world of MVA
Option #1Hours-long traditional sprint planning meetings spent playing planningpoker and a team arguing about the difference between 2’s and 3’s.
Option #2Short story slicing meeting where the focus is on understanding and slicing large stories.
“Do we understand this story? If not, let’s keep slicing.”

The Essence of Agile
Focus
Learning
Simplicity (The art of the work not done.)
(Collaboration is an outcome.)
(Feedback loops enable improvements)
Insist your practices and ceremonies support the “Why” behind Agile!
Customer Value (We wouldn’t be here otherwise.)
Coaching Minimum Viable Agile

Coaching Minimum Viable Agile

Where does Agile go from here?
“What are all the practices we need to adopt to be successful?”
Minimum Viable Agile prompts us to ask:
“Now, what practices do we change ordiscard to be successful?”
