patterns of effective delivery

Jeff Sutterland talks about hyper performing teams

from years to months

PATTERN:

repeatable strategy

depends on context

(vs best practice no context)

has

name

context (where it works)

warning (where it does not work)

best practice -> novice

design pattern book:

!= pattern

idioms to get by in a crappy language

EFFECTIVE:

goal - what are we optimising for

eg.

lead time

time to market

quality

learning

predictability

(agile = predictability)

what are we trading off?

DELIVERY:

"people don't want a quarter inch drill, they want a quarter inch hole"

===

Spike and Stabilize [development]

new code or stable code

no middleground code

not tested

not documented

not fresh: how did this work?

spike

experiment in code

metaphor: nail through wood asap

timeboxed

throw away

real options

options theory + real life

options

have value

expire

"never tie in early"

=> treat all code as a spike

// todo

review of shame

2nd time through

charactarisation test

'test driven testing'

only works if

-> you promise to stabilise

rules

second timeback

test

document

pay for cleanup

set timer

in 6 weeks

===

Hair Trigger [deployment/operations]

team deploys only code

can deploy quickly

can mess up quickly

safety catch

===

Ginger Cake

copying existing code

only code  you knowintimately

- structural

- behavioral

opposite of dry

DRY is a pattern, and has tradeoffs

dark side of DRY

coupling

===

Shallow Silos [team]

NOT "silo bad, cross functional good"

NOT rotation

shared standup

NOT everything or silos

===

Burn the Ships [learning]

I'm gonna build

this thing,

by this date,

using this technology

indirect learning

How lon

"On avarage between 5-15 years for full paradigm shift, because 3 things are needed

1. downward pressure (immovable deadline)

2. run out of options

3. information

So I make friends with companies and wait.

"

-- Eli Goldratt

takes a lot of discipline

"oh shiny, tutorials, look!"
