10. Manifesto for Agile
source from: www.agilemanifesto.org สยามชํานาญกิจ พุทธศักราช ๒๕๕๖
We are uncovering better ways of developing software by doing it and helping others do it.
Through this work we have come to value:
Individuals and interactions over processes and tools
Working software over comprehensive documentation
Customer collaboration over contract negotiation
Responding to change over following the plan
That is,while there is VALUE in the items on the RIGHT, we VALUE the items on the LEFT MORE.

47. Some Facts of Testing
ALWAYS be a chance that software will have bugs
CANNOT prove software works by testing it
DOES NOT prove that software is bug-free
Testing after software has been created DOES NOT
improve its quality
Cost of removing bugs rises DRAMATICALLY in the
later phases of the software development process
QUALITY depends on 3 factors; People, Process
and Tool

48. Some Goals of Testing
Determine a product MEET business expectation
MINIMIZE the risk of error occurs
IS NOT the process to verify software work correct
Testing must be to DEMONSTRATE that software
does have bug
Tester must find bug as EARLY as possible and
make sure that they are fixed

as the 120-tons space shuttle sits surrounded by almost 4
million pounds of rocket fuel..
...the last three versions of the program -- each 420,000
lines long-had just one error each. The last 11
versions of this software had a total of 17 errors...

63. Agile Team
Do same development waterfall team, but do it
very difference
Do same functions as the waterfall method;
requirement-gathering, design, coding and testing
Test as you go, not at the end
Deliver product early and often, as only by
demonstrating working software to customer
Document as you go, and only needed
Build cross-functional team to break down silo
