Introducing Agile
”After I moved to Agile, I don't want to go back
to work in non-Agile projects again”
- Client Developer

Introducing Agile
Agile methodology is an umbrella of software
development methods that are based on shared
values and principles
It focuses on
delivering frequent releases of high-quality
working software
self-organizing teamwork and accountability
● Self-discipline is very important
It embraces changes in a flexible, controlled way

Agile Values
Individuals and interactions over
processes and tools
Working software over
comprehensive documentation
Customer collaboration over
contract negotiation
Responding to change over
following a plan

Thai Cultural Impacts
Afraid of / Reluctant to / Resist to change
Uncomfortable to work closely with senior
management / other departments?
'Yes, boss' attitude
Afraid to show problems until last minutes
This is not my code / problem / work

Pair Programming
Proverb: สองหัวดีกว่าหัว
เดียว
One types (driver), one
thinks (navigator)
Watch out for:
Chitchatting
Dominator
Ping-pong programming

Test Driven Development (TDD)
Little Design Up Front (LDUF)
Test, test, test mentality
Write tests first before implementing new features
Write tests first before fixing bugs
Tests become
Specification
Executable, live documents
Guards

Demo
Story 1
Title: Customer withdraws cash
As a customer,
I want to withdraw cash from an ATM,
so that I don’t have to wait in line at the bank.

Demo – ATM Withdrawal
Scenario 1: Account is in credit Scenario 2: Account is overdrawn past
the overdraft limit
Given the account is in credit
Given the account is overdrawn
And the card is valid And the card is valid
And the dispenser contains cash When the customer requests cash
Then ensure a rejection message is
When the customer requests cash displayed
Then ensure the account is debited And ensure cash is not dispensed
And ensure the card is returned
And ensure cash is dispensed
And ensure the card is returned

Test / Code / Test Cycle
Dev done when we see all dots
With nested option, test result
becomes documentation

Iteration 2
Introduce Agile into your organization
Get executive buy-in
Start with a pilot project
Gradually apply agile techniques
● Daily Stand-up
● Demo every 2 weeks
● Refactoring
● TDD/Test coverage
● Core pair progamming hours
● Retrospective meeting

Practical Advice
Use face-to-face communication
Walk & talk instead of emails
Use whiteboard to show progress, discuss designs
Quick huddle when issues involve more than a
pair
Early release, active feedback
Learn from mistakes as well as try new things
Trust
