Some of the Myths Surrounding Agile
There are many myths surrounding agile development:
Agile is only for small teams
Agile is only for co-located teams
Agile is only for simple systems
Agile doesn’t work for regulatory environments
and many more
In this webcast we are going to explore the myths surrounding whether it’s
possible to scale agile development approaches

The Surveys
All survey data, original questions, and summary slide decks can be downloaded
from www.ambysoft.com/surveys/
If you can’t look at the original questions and analyze the data yourself, how can you trust
the survey results?
Some surveys were done via Dr. Dobb’s Journal (DDJ), a community with a wide
range of readers, not just Agilists
Some surveys, the Ambysoft ones, focused on just the agile community
The source survey(s) are indicated on each slide

Agile Scaling Model (ASM)
Core Agile Development
Focus is on construction
Goal is to develop a high-quality system in an evolutionary,
collaborative, and self-organizing manner
Value-driven lifecycle with regular production of working software
Small, co-located team developing straightforward software
Disciplined Agile Delivery
Extends agile development to address full system lifecycle
Risk and value-driven lifecycle
Self organization within an appropriate governance framework
Small, co-located team delivering a straightforward solution
Agility at Scale
Disciplined agile delivery and one or more scaling factors applies

How does agile compare?
Dr. Dobb’s Journal (DDJ) 2008 Project
Success Survey:
Agile teams have an average success
rate of 70% compared with 66% for
traditional/waterfall teams
Agile teams produce higher quality
work, are quicker to deliver, are more
likely to deliver the right functionality,
and more likely to provide greater ROI
than traditional teams

Myth: It doesn’t matter how distributed you are
Source: Dr Dobb’s 2008 Project Success Survey
Agile approaches require high levels of trust and communication
Distribution reduces trust and makes communication more difficult
Distribution and large team size often go hand-in-hand
