I decided to publish a non-branded version of the keynote I hold about Scrum. These few slides aim at describing the core concepts of Scrum in a lightweight way.

2. Scrum for dummies
Scrum ?
• A simple and efficient project management framework
What it is not...
• The newest trendy/lame buzz allowing developers to screw around

3. Scrum for dummies
Origins of Scrum popularity
Agile Manifesto, created in 2001 by 17 world-class geeks, in reaction to insanely
heavy/inefficient existing project methods.
Emergence of “Agility” word (Scrum has been created in 1995, tho).
4 principles
Individuals and interactions >> processes and tools
Working software >> comprehensive documentation
Customer collaboration >> contract negotiation
Responding to change >> following a plan

5. Scrum for dummies
“Problem”
• Customers do not know what they want
Consequences
• The delivered product does not meet the customer's expectations
• Lots of time wasted on abortive & exhaustive specifications, the workload is
not evenly distributed amongst workers

6. Scrum for dummies
Solutions
• release early, release often
→ small independent working pieces of software (“software increments”,
easier to test!)
→ development industrialization (continuous integration, automatic
testing...)
• involve the customer from the beginning
→ start with something, even inaccurate
→ early demos, early feedback
• specify the present, plan the future
→ accurate backlog items for the closest sprints
→ less precise ideas for the last ones

7. Scrum for dummies
Cycles
Releases fixed-length periods (~2-3 months) broken down into sprints
Sprints fixed-length iterations (~2-4 weeks)
No rules about pushes to production. A push can occur every hour for instance (see Facebook).
Fixed duration but variable perimeter (best effort)
never postpone the deadline but remove something
WHY?
once again, earlier feedback!
cramming is not sustainable
bearable work pace → higher quality

8. Scrum for dummies
Artifacts
Backlog prioritized set of features (releases) or stories (sprints) related
to the product to be delivered
Feature big functional product subset (e.g. “partner access to back-office”)
User Story functional test cases (← these forms the feature specs, check this book)
Example: “As an unlogged user, when I go to my account page, then I am
redirected to the login page.”
Task one technical aspect of a story
they form the sprint backlog
