Who cares how well documented it is if it doesn’t

even work?

Well designed software might not need documentation*

customer collaboration

useless when the market changes overnight, right?

those three months you spent ironing out a contract?

Plan for right now, plan with what you know and, if what you know changes, change the plan,

today!

THAT’S NOT TO SAY YOU

SHOULDN’T BUILD LONGER

ROADMAPS, JUST DON’T SHIT A CHICKEN WHEN THEY

CHANGE (AND THEY WILL)!

To be agile, we value all these core values, we just value the

left ones more!

AGILE PRINCIPLESthey inscribed

the

satisfy the customer1

this is the most important p

rinciple!

our highest priority is

to satisfy the

customer through

early and continuous

delivery of valuable

softwarePhoto by Trish Hamme - http://flic.kr/p/7VU4LC

satisfy the customer1

this is the most important p

rinciple!

Photo by Trish Hamme - http://flic.kr/p/7VU4LC

deliver early,

frequently and don’t

be a dick

welcome change2

welcome changing

requirements, even late

in development. agile

processes harness

change for the

customer's competitive

advantagePhoto by Joelk75 - http://flic.kr/p/msitn

welcome change2

things change,

especially on the web.

don’t moan about it(there are some limit

s though)

Photo by Joelk75 - http://flic.kr/p/msitn

deliver frequently3

Deliver working

software frequently,

from a couple of

weeks to a couple of

months, with a

preference to the

shorter timescalePhoto by Smithsonian Institution - http://flic.kr/p/55juzt

deliver frequently3

deliver as soon as you

can, get feedback

quick. it’s ok to fail

sometimes too, we’re

not all bruce willis

work as a team4

business people and

developers must work

together daily

throughout the project

Photo by The U.S. Army - http://flic.kr/p/B9fcM

work as a team4

your product owner

and your customer

should be treated as

part of your team

Photo by The U.S. Army - http://flic.kr/p/B9fcM

motivate people5

generally thought

to

motivate developer

s

build projects around

motivated individuals.

give them the

environment and

support they need,

and trust them to get

the job donePhoto by russelljsmith - http://flic.kr/p/887JXd

motivate people5

generally thought

to

motivate developer

s

look, unless you hired

morons, then just give

them what they need

and get out of the way

talk, face-to-face6

the most efficient and

effective method of

conveying information

to and within a

development team is

face-to-face conversation

Photo by eye2eye - http://flic.kr/p/5uQF7

talk, face-to-face6

‘meatspace’ can be

tough on devs. there is

no better way to

communicate. irc, im

and email are not

face-to-face. ever

measure software

working7

working software is

the primary measure

of progress

Photo by aussiegall - http://flic.kr/p/rksBi

measure software

working7

the value will come

from having

customers actually

using your software,

measure this

maintain pace8

agile processes promote

sustainable development.

The sponsors,

developers, and users

should be able to

maintain a constant pace

indefinitely

Photo by me'nthedogs - http://flic.kr/p/7dQiBS

maintain pace8

being really agile

means a sustained

output, this means the

whole company. it’s

OK to slow down if

your team changes

excel at quality9

continuous attention

to technical excellence

and good design

enhances agility

excel at quality9

keep your focus on

being technically

excellent and you'll be

super agile

keep it simple10

simplicity -- the art of

maximising the

amount of work not

done -- is essential.

Photo by ejhogbin - http://flic.kr/p/4W4sp3

keep it simple10

try not to do to much

work. doing more work

than you need to is

wasteful and

irresponsible. this isn't

slacking, this is being a

smart worker bee

keep it simple10

try not to do to much

work. doing more work

than you need to is

wasteful and

irresponsible. this isn't

slacking, this is being a

smart worker bee.

however, slacking is ok too, as long as it’s fruitful slacking!

evolve design11

the best architectures,

requirements, and

designs emerge from

self-organising teams

Photo by gds - http://flic.kr/p/d41ch

evolve design11

stop asking your

mother what to do.

evolve yourself, make

time for learning (hint:

it’s not slacking)

Photo by gds - http://flic.kr/p/d41ch

reflect regularly12

at regular intervals, the

team reflects on how

to become more

effective, then tunes

and adjusts its

behaviour accordingly

Photo by pasukaru76 (limited flickr time) - http://flic.kr/p/8DsU6Y

reflect regularly12

your teams need to tune

up regularly, get

together, make sure

you're all in tune. if not,

try something new.

never go backwards.

that’s backwards!
