Agile Software Development

Why is this relevant?

-MARC ANDREESSEN, 2011Software is eating the world

The lessons of Agile are increasingly factoring into business leadership

Software is different• Writing the code = building the production

version • Your engineers and designers are working

on factory floor / Your production workers are responsible for creative process

• Constant learning and refinement as they go

• Quality is directly related to developer ability to creatively problem solve • Complex bugs can be incredibly difficult to

fix

Waterfall

Waterfall problems• Crystal ball business requirements • Analysis and design when we know the least • Big learning is when we code and test • Incorporating big learning into is expensive • Incorporating changed requirements is

expensive

How bad was it?• Data published in 2002: • Software projects needing

complete restart: 94% • Average change in project

requirements: 25% • Average cost overrun: 189%

• Launch delays are the norm • Highly unpredictable = high

business risk

The death spiral

Forced Marches

Decreased Creativity

Decreased Quality

Missed Schedules

Missed Schedules

Something needs to change• Starting in 90’s

experiments with “lightweight” processes • Scrum • Extreme

Programming • Early 2001 17

developers got together and compared notes

Individuals and interactions over processes and tools Working software over comprehensive documentation Customer collaboration over contract negotiation Responding to change over following a plan

The Agile Manifesto

What’s it mean?• Self-organizing teams • Trusted and accountable

• Regular, frequent conversations and cooperation between business stakeholders and the team building. • Lean on those conversations instead of

documentation • Working software produced regularly • Iterate, iterate, iterate • Value calm, regular, sustainable, predictable

pace of product development

Criticism• De-centralized control • Minimal documentation • Too loose • Requires significant behavioral changes • Collaboration • Visibility • Adaptation to feedback and performance

• Breaks down with teams >~10

agile vs. Agile• Eco-system of experts • Trainers • Consultants • Products

• Formalized processes • Rigid • Dogmatic • Lots of overhead

• Losing the forest

Sample Agile Process

1. Sprints

1 week “sprints” that have regular heartbeat

2. Sprint BreakdownEach sprint begins/ends with same set of meetings • Demo - Everyone in company invited to see what

was built in previous week • Retrospective - Team reviews previous week,

answers “what do we want to do more of? What do we want to do less of?”

• Planning - Product owner brings prioritized list of new things to build. Dev team estimates the size of each feature, commits to delivering it in next sprint until their plate is full.

3. Stand-ups

Daily “standup” meetings

• What did you do yesterday?

• What are you going to do today?

• Do you have any roadblocks?

Agile is evolving

10 YEARS AGO: “The shorter iteration the better, you could get crazy and go as short as 2 weeks!”

TODAY: 1 week sprints common

TODAY: Increasing # of teams continuously deploying • Netflix, Etsy pushing 30+ updates a day • Very possible with right infrastructure investment,

corporate values

Agile is evolving

10 YEARS AGO: “Fine for software but my business / product is different”

TODAY: Agile philosophy applied to Sales & Marketing, HR, Management
