Eliminate waste

3 biggest sources of waste Extra features

Develop just those 20% of the features that

give 80% of the value Crossing boundaries

Organizational boundaries typically increasecost by over 25%

Churn Avoid specifying too early, testing too late

Platform-as-a-Service

Google's App Engine we provide the web container, you provide the app supports Java and Groovy

Platform services Datastore memcache URLFetch with Secure Data Connector Mail Google accounts based authentication Simple cron-based scheduling

Data Center as a Service

Amazon EC2 you provide the machine images, we provide

the data center more to do than PaaS model but more control can exploit pre-built machine images

Data center services S3, EBS, SQS, DevPay, CloudFront,

SimpleDB, ...

Create knowledge

Planning is useful, learning is essential Standards exist to be challenged and

improved Embody the current best-known practice in

standards, encourage challenging of them Predictable performance is driven by

feedback

Do not guess about the future and call it aplan. Develop the capacity to react as thefuture unfolds

Use the scientific method

Deployment blueprints

Firing up a single image, or set of identicalimages is useful in the simple case

SpringSource value: simple and powerful...

Most production use cases require a set of co-operating machines, playing differing

roles

Lean software principles

Defer commitment Abolish the idea that it is a good idea to start development with a

complete specification Break dependencies

Maintain options Schedule irreversible decisions at the last responsible moment

Deliver fast Rapid Delivery, High Quality, and Low Cost are Fully Compatible

Companies that compete on the basis of speed have a big cost advantage, deliver superior quality, and are more attuned totheir customers' needs.


46/47


Lean software principles

Improve the system Brilliant products emerge from a unique combination of

opportunity and technology. Focus on the Entire Value Stream

from concept to cash from customer request to deployed software

Deliver a Complete Product Develop a complete product, not just software. Complete

products are built by complete teams. Measure UP
