Product QA: Why it is Tough

1. Product is more than software
   • Software application
   • Platform and variations
   • Documentation: online help, manuals, tech briefs, examples,
     training
   • Add-ins and third party product integrations
   • Installation experience
   • Handling upgrades and updates

2. Quality is more than lack of bugs
   •   Does it solve the problem when it works?
   •   Is it practical to use? Is it designed for efficient use?
   •   Does it keep working or works only under ideal conditions?
   •   Is it economical to build, maintain and respond rapidly to
       customer/user needs?
Role of QA in Product Company

• QA is everything you do to minimize risk of failure and
  promote excellence
• Help producing products that satisfy target customer
  base
• Broad functions of QA
   –   Risk management: release planning, release approval
   –   Bring customer involvement: early release programs
   –   Act as skillful developers: mimic tough customer!
   –   Process definition and improvement
   –   Inspection and testing
   –   Experience-based improvement: contribute to product
       definition, many finer points
• Should play an important role throughout The Life of a
  Product

QA Planning

•   What QA is required to do
•   QA procedures, expectations from other teams
•   Effort estimation and team planning
•   Resource planning, tools and software
    procurement
Process Definition & Improvement

• Assessment of the state of the processes
• Setting process goals and reviewing
• Recommendations for improvement with
  justification
• Action plan for implementing improvements
Test Suite Design

• Design the tests in parallel to software design
• Tests need organization into independent test
  suites
• Build the tests before you build the software
• If you find a bug, write a test that proves the bug
  exists, fix the bug and then rerun the test to
  prove it is fixed
Test Suite Design Review

• Goal: Clarification and accept/reject design
  decisions
• Starts with a presentation of the design for the
  component/module to a selected panel of
  developers
• Peer review is commonly used, with most
  relevant engineers from other parts of the
  product included
• Discussion and coordination of comments
  incorporation
Check-in Review & Code Walkthrough

• Check-in review done with peers of the dev team
   – Including new features and bug fixes
• Code walkthrough by dev across streams,
  including QA
   – review meeting with prepared participants
   – Sample source files are selected for review
• Focus is on finding defects, before they slip
  through to testing phases
   – Lower costs by catching them early
Early Release Programs

• Need to ensure smooth porting of current
  customers
• Test ISV applications available internally
• Public program to increase the test base
   – Alpha and Beta testing
Release Readiness

• QA evaluates quality, independent of developers
   – Developers should not determine how much quality is
     sufficient
• QA acts as internal customers and verifies
  release readiness

Product QA - A test engineering perspective

  • 1. Product QA – A Test Engineering Perspective E N S U R I N G P R O D U C T S A R E T E S T E D T H E W A Y T H E Y W I L L B E U S E D Copyright (c) 2009, Pramati Technologies Private Limited.

  • 2. Product QA: Why it is Tough 1. Product is more than software • Software application • Platform and variations • Documentation: online help, manuals, tech briefs, examples, training • Add-ins and third party product integrations • Installation experience • Handling upgrades and updates 2. Quality is more than lack of bugs • Does it solve the problem when it works? • Is it practical to use? Is it designed for efficient use? • Does it keep working or works only under ideal conditions? • Is it economical to build, maintain and respond rapidly to customer/user needs?
  • 3. Role of QA in Product Company • QA is everything you do to minimize risk of failure and promote excellence • Help producing products that satisfy target customer base • Broad functions of QA – Risk management: release planning, release approval – Bring customer involvement: early release programs – Act as skillful developers: mimic tough customer! – Process definition and improvement – Inspection and testing – Experience-based improvement: contribute to product definition, many finer points • Should play an important role throughout The Life of a Product

  • 9. QA Planning • What QA is required to do • QA procedures, expectations from other teams • Effort estimation and team planning • Resource planning, tools and software procurement
  • 10. Process Definition & Improvement • Assessment of the state of the processes • Setting process goals and reviewing • Recommendations for improvement with justification • Action plan for implementing improvements
  • 11. Test Suite Design • Design the tests in parallel to software design • Tests need organization into independent test suites • Build the tests before you build the software • If you find a bug, write a test that proves the bug exists, fix the bug and then rerun the test to prove it is fixed
  • 12. Test Suite Design Review • Goal: Clarification and accept/reject design decisions • Starts with a presentation of the design for the component/module to a selected panel of developers • Peer review is commonly used, with most relevant engineers from other parts of the product included • Discussion and coordination of comments incorporation
  • 13. Check-in Review & Code Walkthrough • Check-in review done with peers of the dev team – Including new features and bug fixes • Code walkthrough by dev across streams, including QA – review meeting with prepared participants – Sample source files are selected for review • Focus is on finding defects, before they slip through to testing phases – Lower costs by catching them early
  • 14. Early Release Programs • Need to ensure smooth porting of current customers • Test ISV applications available internally • Public program to increase the test base – Alpha and Beta testing
  • 15. Release Readiness • QA evaluates quality, independent of developers – Developers should not determine how much quality is sufficient • QA acts as internal customers and verifies release readiness
