The Evolution of IT

The IT Department

The Consumer

The Developer

The IT Department

The 90s: Cost Center

IT considered a cost center

Hub of IT

Technical decisions made by IT

The 00s: Key Infrastructure

IT deployments driven by business need

Technical direction driven by management

Still a cost center

Now: Morphing IT

Carefully planned IT investments

Customer driven

Potential profit center

The Consumer

The 90s: PC Generation

Windows and the PC are standard business tools

The 00s: The Internet Generation

Consumers embrace the Internet as a fundamental part of their lives

Now: The Mobile Generation

Mobile devices become the tool for Internet access

Who is the Consumer?

The customer buying from us

The employees working for us

How they consume IT has changed their expectations

Find bugs, fix bugsHigh-value exploratory testing; Test features not stories; Fix bugs immediately

There’s no place like production

Questions?

Where to start?

Build a backlogPrioritize work 1..nRuthlessly increase the granularity

Plan an iterationShorter is betterCommit to a concrete goal

Define done, doneStandards to checkin, complete a story, and finish an iteration

Hold a daily standupNot a status meetingCommunicate your plan for the day

You get what you inspect, not what you expect

Make the work visibleAttend the sprint review, put hands on the product, hold the team accountableInstill engineering disciplineUnit testing, continuous integration, code reviews, and rolling builds are a mustA failing test is worse than no test

Focus on business valueMeasure your progress against customer satisfactionAlign crews to strategic initiatives

Emphasize small batchesWithout doubt the most challenging thing in moving to an agile cycleUse Kanban with agile practices to see the bottlenecks
