A quick review of Scrum

Why Scrum?
Scrum is the most efficient way of going from an idea to high quality code in production, that I know of Scrum teams can push code into a production every two weeks (although they don’t have to)

How is this possible?
How can a team build a complete functional application in two weeks? What if the architectural framework takes two months to build? What about the quality of the code?

How can a team build an app. in two weeks?
They cannot ... However they can build some functional slice of the application, and They can build the highest priority piece of functionality

How can a team build an app. in two weeks?
Sushi Slices Each slices is part of the complete whole Each slice can stand on it’s own This equates to slices of functionality in software

How is this possible?
How can a team build a complete functional application in two weeks? What if the architectural framework takes two months to build? What about the quality of the code?

What if it takes two months?
60% of functions are never used, So, why not deliver the 40% that will be used and build the rest when we need it? Only build what you need right now

How is this possible?
How can a team build a complete functional application in two weeks? What if the architectural framework takes 2 months to build? What about the quality of the code?

What about the quality of the code?
Agile Engineering practices are necessary in order to achieve this Continuous Integration, TDD and (now) Continuous Deployment

What about the quality of the code?
“Software is an organizational asset and decisions to cut quality must be made by executive management and reflected in the financial statements.” “Canary in the Coal Mine,” Ken Schwaber

Trends in adopting Scrum
The adoption of Scrum has changed over the years as Scrum has become more mainstream Once the domain of risk takers and early adopters, Scrum is now being adopted by a different group of people with different motivations

Reason #3
“At risk” projects They frequently have nothing left to lose Desperate teams will try anything

Reason #2
Not meeting market demand Does it take 4 months to get and approvel PRD? Do you write more documentation than software?

Reason #1
Your competitors are using Scrum If you’re competitors are using Scrum, it’s not a level playing field ... they’re playing a different game.

Summary
Why Scrum? Because it’s the most efficient way to go from concept to high quality code in production Scrum changes the business of software
