A Brief Historyhttp://www.senseoncents.com/wp-content/uploads/2012/07/Declaration-of-Independence1.jpg
On February 11-13, 2001, mountains of Utah, seventeen people met to talk, ski,. What emerged was the Agile Software Development Manifesto. Representatives from Extreme Programming, !Now, a bigger gathering of organizational anarchists. !The only concern with the term agile came from Martin Fowler most Americans didn’t know how to pronounce the word agile.

12 Principles of Agile• Our highest priority is to satisfy the customer through early and continuous delivery of valuable software.
• Welcome changing requirements, even late in development. Agile processes harness change for the customer's competitive advantage.
• Deliver working software frequently, from a couple of weeks to a couple of months, with a preference to the shorter timescale.
• Business people and developers must work together daily throughout the project.
• Build projects around motivated individuals. Give them the environment and support they need, and trust them to get the job done.
• The most efficient and effective method of conveying information to and within a development team is face-to-face conversation.
• Working software is the primary measure of progress.
• Agile processes promote sustainable development. The sponsors, developers, and users should be able to maintain a constant pace indefinitely.
• Continuous attention to technical excellence and good design enhances agility.
• Simplicity--the art of maximizing the amount of work not done--is essential.
• The best architectures, requirements, and designs emerge from self-organizing teams.
• At regular intervals, the team reflects on how to become more effective, then tunes and adjusts its behavior accordingly.

Adaptive Vs Predictive

Shit happens so stop pretending
Project Andiamo
That doesn’t mean you don’t plan
Project Andiamo
You plan around being wrong

If you’re building something new you’re free climbing
We had to persuade the business that they didn’t know where they were going they just broadly knew the destination

Scrum
"a flexible, holistic product development strategy where a development team works as a unit to reach a common goal"
as opposed to a "traditional, sequential approach".

Story Points
Project Andiamo
When is it good?• Your team works together in the same place at the
same time
• Multiple development teams
• Defined roles
• You need discipline

Project Andiamo
When is it good?
• Your team is in different places and works at different times
• Experienced and confident team
• No politics
You can lay Kanban over the top of SCRUM Kanban itself is not a software development process

Principles I’ve Learnt• Users first
• Use cases are mandatory
• We aim to fail fast
• We will make mistakes, we accept this and mitigate losses up front
• Everything we build is
• Quickly iterative
• Disposable
• Doesn't constrain future growth
• Agnostic
• We always test (e.g. TDD, BDD) but real world tests are more important
• The value in the future is context. How we get insights, make better decisions, and tell stories with that data

One Question
Project Andiamo
What is the fastest, cheapest, and best way to screw this up?
All these things are just tools they won’t stop you screwing stuff up
Project Andiamo
Now iterate
