AGENDA

Agenda

• The case for QA in an Agile World

• Changing role of QA in an Agile World

• Role of QA in Agile organizations

• Profile of Testers and QA Analysts for these

organizations

• Automation best practices

• Metrics and measurements

The Case for QA in an Agile World

The Promise of Agile

Develop iteratively as business evolves

Deliver working software rapidly

Flexibility to change with business needs

Incorporate end-user feedback

Highly productive technical teams

Agile Challenges

Functionality/defect treadmill

High regression defect seepage

“Epic” failures

Non-functional requirements fail

Low effective team throughput

What Agile Assumes

Communication

Collaboration

Access to Stakeholders

Cross Functional Teams

Is QA Dead in this Agile World?

Some Agile proponents did not see (or argued against)

the need for QA specialists on an assembled team.

If you use TDD, Unit Testing & “Everyone Tests their

own Stuff” do we need a dedicated QA team?

Role of QA in an Agile World

Organization empowers Health plans to transform the performance of their provider networks, while significantly reducing medical, administrative and IT costs and simplifies the design, maintenance, reimbursement and performance management of provider networks, while facilitating provider-patient collaboration.

Development Objectives:

• Rapid release of new solutions and rich new features of their core Platform into market to take advantage of increased health care IT spending in the payer market due to health insurance reform (PPACA)

• Ensure high level of customer satisfaction dependent on user experience, maintainability, scalability and platform performance

• Ensure the highest levels of security and confidential data access meeting all regulatory needs and customer specific needs

Development Organization:

• TDD approach for Developers engaged in 2-week sprint cycles

• Enterprise development technologies

• Interfaces with several in-house and 3rd party development teams and applications

• SCRUM, Kanban and Lean techniques

Infrastructure

• Re-usable automated test suites with minimal maintenance effort

• Cross application E2E automated testing

• Excel based test suite

• Detailed test summary reports along with step wise description and screen shots

• Test scripts, test reports integrated with QMS

• Automated 55% of regression scenarios which includes 70% of business critical scenarios.

Test Automation Framework

Metrics

Measuring Effectiveness

Automation initiatives need metrics reporting and analysis as an integral part of the

initiative to ensure success of the initiative.

• Metrics should capture both business level and execution level values

to ensure efficiency is accurately captured and reported

• Metrics should not be left for the end of the project to implement

• Metrics measurements allow implementation level course corrections or

expectations management easier

• Business Objectives outlined should be directly tied to the metrics

program and measured through out the initiative

• Assumptions and approximations can be made at the beginning of the

initiative

Key Metrics for Agile Projects

• Use Validation points to evaluate application’s map with requirements

• Communicate to all stakeholders the coverage provided by formal testing

Coverage Metrics

• Number of defects identified in different stages of software lifecycle

• Number of defects created in different stages of software lifecycle

Defect Identification Efficiency

• Quality of software code

• Impact of technical or architectural choices Technical Debt

• Demonstrate the confidence of the testing team in the testing efforts executed on a release with the resources provided for testing Confidence Level

Metrics & Effectiveness Measurements Detailed execution metrics will be captured to glean insights about test process, execution and

SDLC process.

Coverage Metrics

Principle

Communicate to all stakeholders the coverage provided by formal testing

Dimensions

• Use Validation points to evaluate application’s compliance with requirements

• Weight them by business criticality

Definition

Designed Coverage = Designed Validation Points / All Validation Points

(Estimated)

Executed Coverage = Executed Validation Points / All Validation Points

(Estimated)

Best Practices

• Keep coverage metrics simple

• Introduce granularity to address business needs

• Trend to show progress (or declines – great case for additional resources)

Defect Identification Efficiency

Principle

Identify how defects are identified and created. Evaluate compliance of Agile

principles.

Dimensions

• Number of defects identified in different stages of software lifecycle

• Number of defects created in different stages of software lifecycle

• Use key Software stages to draw valuable inferences

Definition

Proportion of defects identified by each stage of a lifecycle – Ex – Testing –

56%, UAT – 18%, Production - 4%, other - 22%

Best Practices

• Start with defects identified first – then introduce defects created

• Use “Other” to catch exceptions and introduce granularity incrementally

• Factor in defect severity if that information is readily available

Technical Debt

Principle

Provide a financial impact of technical choices on the overall product resulting

from technology, process and implementation choices made during

development

Dimensions

• Quality of software code

• Unresolved defects that are business or quality critical

• Impact of technical or architectural choices

Definition

Cost estimates for redressing most critical (Business perspective) defects or

technical choices

Best Practices

• Explosive- Handle and communicate with care

• Be conservative – use a very strong criteria to evaluate “criticality” • Use several available tools to evaluate software code quality

Confidence Level

Principle

Demonstrate the confidence of the testing team in the testing efforts executed

on a release with the resources provided for testing.

Informational

• Test Execution Coverage

• Expertise of resources to test the application

• Quantitative results of defects including Defect identification efficiency

Definition

Based on the evaluation of the 3 dimensions above rank each of them on a

scale of 0(Poor) – 1(High). Overall confidence =

(3.Coverage.Resources.Results)/(Coverage+Resources+Results)

Best Practices

• Be prepared with supporting facts

• Define clearly laid out criteria for ranking
