DESCRIPTION
A talk I gave at the SUGSA July meeting about managing complexity and information rates in agile software development. Some topics such as information rate and user stories are identified as key factors in the success when there is levels of uncertainty and ambiguity present. Also a basic understanding of Cynefin, was presented to help individuals better categorise the problems that are evident in everyday software development environments

USING AN AGILE TYPE PROCESS AS A RESPONSE TO COMPLEXITY
DEALING WITH COMPLEXITY BY ITERATING
Iterations can help with controlling the amount of information*
Oh BTW “we”
hate iterating
THIS IS ITERATING
THIS IS INCREMENTING
Iterating starts before the iteration, it’s a mindset driven by being comfortable
with complexity

NARRATE ME YOUR PROBLEM
USER STORIES
The role of narrative is very important
As a: .... I want:.... So that....
It seems people really struggle at writing
stories
2 theories
Why
Our natural inclination is to solve problems
trying to fit the problem in the little
blocks
Remember the Gorilla?
Everything we do is empirical in nature, but we have a
standard user story format.
What the?
So what should a user story look
like?
Without our user story format we would miss this
awesomeness
