The ability to use, develop, integrate and deliver custom software is strategic for most organizations

However, unlike other strategic business processes, there are often large gaps – which creates risk:No consistent processes are being applied to the development and management of custom software.

Reporting on developer productivity, software quality and business value is missing.

Development processes and activities are not predictable and repeatable.

Complexity of software (and value opportunities) grow without associated maturity and team capabilities

Business Runs On Software

How well a firm executes itsbusiness strategies is tied to how

good it is at creating and managing

custom applications!David Chappell

BUT

Software development is difficult, takes a long time, costs a lot of money and

often fails!The Voice of Experience

At First, It‘s Easy

Over Time, Things Get Complicated ...

So, Management Is Added …

… And Process …

… Which Leads To Specialization …

… And Adding Of Indirect Labor …

But Wait – There’s More!

Business demand outpaces the abilityof developers to deliver applications

From “Testing“ to “Quality Enablement“

Measuring Quality

Common Quality Issues and Blockers

Blocker: Misunderstood Requirements

Requirements don’t reflect customer intentRework, long delivery cycles and frustration.

Storyboarding ToolGraphical mockups and visual prototypes in new PowerPoint add-on reducemisunderstandings and clarify intent.

Feedback ManagerStand-alone feedback tool allows stakeholders to provide comprehensive feedbackon any artifact, including storyboards, directly to development teams.

Blocker: Quality is an Afterthought

Quality not built in from the startFailure to meet user needs, rework, long delivery cycles and customer dissatisfaction.

Unit TestingExtensible unit test framework targets specific needs or technologies to ensure code correctness.

Fakes and stubs frameworkPowerful mocking framework to simplify unit testing and isolate logic.

Exploratory TestingAd-hoc exploratory tests help uncover usability and consistency issues, and resultin actionable bugs and reusable test cases.

Session 03Test Specification and Execution

Blocker: Unmet Operations Readiness

Delivered code fails to perform as plannedFailure to meet IT maintenance needs, rework, long delivery cycles and customer dissatisfaction.

Web TestingLightweight web tests validate correct functionality and behavior, both in testing and production.

Load TestingPowerful load test frameworks simulates thousands of simultaneous usersto ensure performance, stability and uptime.

Blocker: Can’t Get Actionable Feedback

Delayed feedback on code changesFixing critical bugs takes a long time, increases in context switching,rework and long delivery cycles.

Continuous IntegrationBuild, deploy and test complex applications on every check-in toquickly identify problematic code changes.

Lab ManagementSelf-service test lab provisioning speeds manual and automated build-deploy-test feedback cycles.
