Requirement Quality

• 3Cs (Card, Conversation, Confirmation)

• INVEST in User Stories

• Acceptance Criteria



  Product Owner owns it BUT the team gets
  engaged in requirement quality


                                    © Alliance Global Services 2012   6
Architecture & Design Quality

• Incremental Design

• Flexibility

• Design for Testability

• Spikes & POCs

• Static & Run-Time Code Quality Check
    – CAST, Profiling Tools

• Refactoring


 The Whole Team Participates In the Architecture
 & Design Discussions
                                         © Alliance Global Services 2012   7
Code Quality

•   Continuous Integration Platform – Jenkins / Customized
    to meet the need
•   Early Feedback
     – Everyone sees what's happening at the code quality
       level
•   Automated Unit Test Integration
     – Run the unit tests and publish test and coverage
       reports
•   Code Analysis
     – CheckStyle, PMD, Findbugs, FxCop, StyleCop, Open
       Tasks, duplicate code
•   Automatic Deployments
     – Reduce human error, fast, everyone can
       deploy, daily deployment to test/integration
       environment
                                                             © Alliance Global Services 2012   8
Baked-In Quality Context

                        Quality Context

• Measuring weight 10 times a day doesn’t reduce weight –
  Verification & Validation doesn’t increase the quality of the
  software
• Client wants features not bugs and expects the bugs will be
  taken care of above & beyond the functionality planned.
• Anything needs to be done requires resource and time
  allocated for it
• A bug is like a tiger. When it’s a cub easy to handle before it
  grows over time
• Saying “Yes” to bugs increases the probability of more bugs
  in future
                                                 © Alliance Global Services 2012   9
Baked-In Quality Early in the Cycle
                                 Quality User Stories with
                                 Defined Acceptance
                                 Criteria

                                 Alliance Engineering
                                 Platform (AEP) provides
                                 continuous feedback on
                                 standards & best practices


                                 Daily un-scripted
                                 exploratory testing and
                                 removal of defects help
                                 increasing the quality of
                                 the software


                                 Peer Review & External
                                 Engineering Audit helps in
                                 early detection of
                                 weaknesses and help in
                                 building robust commercial
                                 grade software



                                      © Alliance Global Services 2012   10
Verification & Test Automation

• Acceptance Test Automation

• In-Sprint Automation

• Regression Test Automation

• Developer & Tester Pairing for Increasing the Quality
  of the software instead of just measuring it
• Incentivize People for the right behavior
   – No bugs found at the verification stage is the goal

Maturing Definition of Done

• What it takes to deliver to production?
• How much of it covered as part of the Sprint?
• Anything which may cause rework for quality must
  be part of Definition of Done
• Maturing Definition of Done shows the maturity of
  the team
• Investing in Definition of Done helps producing
  quality software

  • 1. Baking-In Quality in Agile Scrum Model Agile Hyderabad Workshop for Scrum Practitioners Date September 26, 2012
  • 2. Discussion Topics • Quality Driven by the Scrum Model • Vision To Requirement Quality - JumpStart • Architecture & Design Quality • Code Quality • Baking-In Quality • Verification & Test Automation • Maturing Definition of Done © Alliance Global Services 2012 2
  • 3. Agile Scrum Delivery Context Doing THINGS Right Doing RIGHT Things • Unit Testing • Working software after each iteration for user review • Test Automation • Frequent Customer Review & Feedback • Manual & Automated Code Review • Accommodate Change after each iteration • Automated Continuous Integration • Focus on the most impactful features first • Incremental Design & Architecture • Frequent Inspect & Adapt for course • Refactoring to Reduce Technical Debt correction  Individuals & Interactions  Customer Collaboration Doing Things FAST  Engineering Best Practices  Demo Working Software  Frequent Inspection & Adaptation  Respond to Change • Partnership To Work Together • Reduce Uncertainty & Delays • Minimize waste by producing less consumable artifacts • Self-Managed Experienced Team • Eliminate Impediments  Self-Managed Experienced Team • Automation  Eliminate Delay & Impediments  Automation • Maximize Value Early © Alliance Global Services 2012 3

JumpStart - Inception An accelerated process to transform the product vision in to an Actionable Plan and Architecture ready for implementation Week 1 Week 2-3 Week 4 High Level Implementation Estimate Business Persona Package Complete Approach & Drivers Definition Approach Architecture Short List Draft Architecture Alignment Tool Identification Data Catalog Requirements Plan Release Plan User Flows Competitor Review or Wireframes Shelf Docs © Alliance Global Services 2012 5
  • 6. Requirement Quality • 3Cs (Card, Conversation, Confirmation) • INVEST in User Stories • Acceptance Criteria Product Owner owns it BUT the team gets engaged in requirement quality © Alliance Global Services 2012 6

  • 8. Code Quality • Continuous Integration Platform – Jenkins / Customized to meet the need • Early Feedback – Everyone sees what's happening at the code quality level • Automated Unit Test Integration – Run the unit tests and publish test and coverage reports • Code Analysis – CheckStyle, PMD, Findbugs, FxCop, StyleCop, Open Tasks, duplicate code • Automatic Deployments – Reduce human error, fast, everyone can deploy, daily deployment to test/integration environment © Alliance Global Services 2012 8
  • 9. Baked-In Quality Context Quality Context • Measuring weight 10 times a day doesn’t reduce weight – Verification & Validation doesn’t increase the quality of the software • Client wants features not bugs and expects the bugs will be taken care of above & beyond the functionality planned. • Anything needs to be done requires resource and time allocated for it • A bug is like a tiger. When it’s a cub easy to handle before it grows over time • Saying “Yes” to bugs increases the probability of more bugs in future © Alliance Global Services 2012 9
  • 10. Baked-In Quality Early in the Cycle Quality User Stories with Defined Acceptance Criteria Alliance Engineering Platform (AEP) provides continuous feedback on standards & best practices Daily un-scripted exploratory testing and removal of defects help increasing the quality of the software Peer Review & External Engineering Audit helps in early detection of weaknesses and help in building robust commercial grade software © Alliance Global Services 2012 10
  • 11. Verification & Test Automation • Acceptance Test Automation • In-Sprint Automation • Regression Test Automation • Developer & Tester Pairing for Increasing the Quality of the software instead of just measuring it • Incentivize People for the right behavior – No bugs found at the verification stage is the goal © Alliance Global Services 2012 11
  • 12. Titanium xAFT – Functional Test Automation Titanium xAFT is a Open-Source Test Automation Framework to develop Automation rapidly across the enterprise while creating highly maintainable suites. • Readable scripts rather than programming allows functional testers to develop and maintain scripts • Abstraction of object ids, test data and test scripts allow for in-sprint automation • Modular design and underlying support for multiple frameworks and tools are used to develop complex automation • Provides single interface to develop end to end automation for Web 2.0, Web Service, database and mainframe • Detailed reporting, screen play, screenshot and service Cross-browser Mobile Web Services request/response capture allow for auditable test results Titanium xAFT Interactive Demo: http://www.allianceglobalservices.com/resources/webinars/20#.UGE5UI3iZ_g Titanium xAFT Download: http://allianceglobalservices.com/innovation © Alliance Global Services 2012 12
  • 13. Maturing Definition of Done • What it takes to deliver to production? • How much of it covered as part of the Sprint? • Anything which may cause rework for quality must be part of Definition of Done • Maturing Definition of Done shows the maturity of the team • Investing in Definition of Done helps producing quality software © Alliance Global Services 2012 13
