For commodity projects, we need to focus on
business value
For strategic projects, we need to focus on risk
mitigation

13. #enterprisekanban
To mitigate product risk, focus on learning
Market Risk: Make cheap prototypes and validate
them with your target market
Technology Risk: Spike early to understand
technical challenges
Don't (yet) worry about quality or delivering every
sprint

30. #enterprisekanban
Class of Service Criteria
Expedite Emergency bug fixes that need
to be fixed and deployed in a
few days
Fixed Date Features that have a fixed
deadline
High Uncertainty Features exposed to market or
technical risk.
Basic Basic features from the Kano
model
High Value Differentiating features from
the Kano model
Slack Intangible, long term
improvements, to be picked up
during times of slack
Normal Everything else

31. #enterprisekanban
Expedite
* Only for emergency bug fixes
* Moves to the head of backlog and all queues
* Can override work in progress limits
* Team members stop whatever they are working
on and swarm to complete this work item
sales@toolsforagile.com @toolsforagile facebook.com/ToolsForAgile

32. #enterprisekanban
High Uncertainty
* High market or technology risk
* Skip automated test stage
sales@toolsforagile.com @toolsforagile facebook.com/ToolsForAgile

33. #enterprisekanban
High Value
* Requires user experience stage
* Requires additional automated tests
* Requires additional manual exploratory tests
sales@toolsforagile.com @toolsforagile facebook.com/ToolsForAgile

34. #enterprisekanban
Slack
* Scheduled during slack periods
sales@toolsforagile.com @toolsforagile facebook.com/ToolsForAgile

Risk oriented view
What if you have many high uncertainty items on
the backlog?
What if you have no high certainty items on the
backlog?
sales@toolsforagile.com @toolsforagile facebook.com/ToolsForAgile

37. #enterprisekanban
Risk oriented view
What is the mixture of basic, linear and
differentiating work items?
sales@toolsforagile.com @toolsforagile facebook.com/ToolsForAgile

38. #enterprisekanban
Risk oriented view
Can we amortize highly risky features over a period
of time by breaking them down into smaller pieces
and tackle them one by one?
sales@toolsforagile.com @toolsforagile facebook.com/ToolsForAgile

39. #enterprisekanban
Risk oriented view
Should we balance a release containing a high
uncertainty feature with well understood basic
features?
