Notable Agile Variants LEAN - 1990 • Kaizen – continuous improvement • Kanban boards Extreme Programming (XP) – 1999 • Refactoring • Pair Programming • Small Releases • Testing • Continuous Builds Scrum - 2001 • Borrowed from LEAN and XP • Formalized the process with Stand-ups

Slide 21

Agile – Scrum Variant 2-4 week sprint Build Product Backlog Determine sprint backlog Analysis Development Testing Acceptance Design Release Daily Stand-ups Retro- spectives Stake- holder Demo

Agile – User Story Considerations • Business value • Development effort • Complexity • Known unknowns

Slide 23

Slide 23 text

Agile – Observation People are bad at estimating, but are good at comparing.

Slide 24

Slide 24 text

Agile – Story Priority Example 7 bv / 1 sp = 7 7 bv / 144 sp = 0.049 58 bv / 12 sp = 4.83 Business Value / Story Points (aka Development Effort) = Story Priority

#3 CI, CD and the other CD IF SOMETHING IS HARD AND ERROR-PRONE, DO IT MORE OFTEN

Slide 33

Slide 33 text

Continuous Integration The practice of compiling code found within a repository frequently.

Slide 34

Slide 34 text

Continuous Deployment The practice of deploying a compiled solution in its entirety to a host or set of hosts, typically to be tested by an automated testing framework.

Slide 35

Slide 35 text

Continuous Delivery The practice of deploying a compiled solution in its entirety to production servers.

Slide 36

Slide 36 text

Automated Testing Let’s let the computers run tests instead of humans. Computers are more thorough, more reliable and lot quicker.
