agile manifesto
Individuals and interactions over processes and tools
Working Softwareover comprehensive documentation
Customer colaborations over contract negotiation
Responding to change over following a plan
all about peopleeveryone wishes to do a good job
summary
eXtreme Programming
reviewing values
do what is needed, but no more.
maximize the value created.
take small simple steps to our goal.
mitigate failures as they happen.
simplicity
Everyone is part of the team and we communicate face to face daily.
We will work together on everything from requirements to code.
communication
We will take every iteration commitment seriously by delivering working software.
We demonstrate our software early and often then listen carefully and make any changes needed.
feedback
Everyone gives and feels the respect they deserve as a valued team member.
Everyone contributes value even if it's simply enthusiasm.
Developers respect the expertise of the customers and vice versa
respect
We will tell the truth about progress and estimates.
We don't fear anything because no one ever works alone.
We will adapt to changes when ever they happen.
courage
practices
As a user closing the application,I want to be prompted to save anything that has changed since the last save so that I can preserve useful work and discard erroneous work.
user stories
planning poker
first the developer writes a failing automated test case that defines a desired improvement or new function,
then produces code to pass that test and
finally refactors the new code to acceptable standards.
test driven development
"disciplined technique for restructuring an existing body of code, altering its internal structure without changing its external behavior"
Advantages include improved code readability and reduced complexity to improve the maintainability of the source code.
refactoring
the four variables
evolutions
It extends TDD by writing test cases in a natural language that non-programmers can read.
behavior driven development
Feature: Division In order to avoid silly mistakes Cashiers must be able to calculate a fraction
Scenario: Regular numbers * I have entered 3 into the calculator * I have entered 2 into the calculator * I press divide * the result should be 1.5 on the screen

what have you done since yesterday?
what are you planning to do today?
any impediments/stumbling blocks?
what went well during the sprint?
what could be improved in the next sprint?
all about an empirical process to deliver quality software oftenassumption: committed people and flat maintenance cost
summary
lean startup
part 1: problem/solution fit
part 2: product/launch fit
part 3: product/market fit
are you ready to learn from customers?
do you have a problem worth solving?
have you built something customers want?
scale
all about validating business assumptions and maximizing the delivered value.assumption: committed people, flat maintenance cost and deliver quality software often
summary
what do you need? committed people flat maintenance cost quality software delivered often validate business assumptions maximize delivered value
result: scalable business model
