5. Pros and Cons
● Evolution rather than revolution
● Agnostic to software engineering and management
practices
● When 1 week iteration is too long
● Cadence taking form of average lead time
● There are “idle” people
● Identifies micro-level problems
● Protecting people
6. Pros and Cons
● Just giving names and structure to common sense
ideas
● May give no advantage, e.g., compared to
timeboxing
● Main effect may come from just-in-time planning
and estimating
● More suitable for unpredictable loads
● Not a complete sofware lifecycle tool
7. Reality
Dev 1 Dev n QA 1 QA n Operations
Projects
Maintenance &
Support
On hold
● Daily delivery “trains”
● Same team doing development and maintenance
● Experienced and reliable people
● Hold - if a much higher priority task comes in
● No visualisation on a common board
● Improving just-in-time'ness of prioritisation
