© 2012 WIPRO LTD | 7 Pattern Documentation Name: A short descriptive pattern name Context: Description of the context; derived from the Example Problem: The underlying question Forces: Why it is a problem? Solution: The basic idea of the solution Consequences: Outcome of using the pattern Known Uses: Know applications of the pattern in practice Related Patterns: Relationship with other patterns

© 2012 WIPRO LTD | 8 Name: Process Based Pattern Context: One of the US based insurance organization faced challenges in comparing and consistently measuring quality levels across Line Of Business (LOB) as each LOB followed different SDLC model. Problem: What is the Testing Strategy to address Quality Assurance (QA) requirements while migrating multiple programs to common baselined process? Test Strategy Levers What To Address?Impacts Test Methodology  Standardization of Methodology across LOB  Effective means to address change management Standardization of QA metric and report generation Test Process  Process Definition to support BAU without disruptions  Methodical approach to process changes (avoid big bang changes) Operational Support for ongoing projects People SkillsTraining to adopt to new processPeople enablement to successful rollout of redefined process

© 2012 WIPRO LTD | 9 Name: Technology Diverse Pattern Context: One of the US based Insurance Organization had developed applications using different technologies for Life Insurance and Non-Life Insurance. Problem: How to devise test strategy for disparate technology based solutions? Test Strategy Levers What To Address?Impacts People Skills  Build a map of people with specific technological skills to be put to use at various stages of test execution Ensuring availability of people with right skillsets Test Process  Process definition to address technological dependencies Avoidance of dependency that could potentially affect test schedule Test Environment  Well defined test environment requirements  Define a schedule to indicate at what stage of execution it should be made available  Identify required tools and what stage of execution it will be required Optimal usage of test environment and tools Test ManagementIdentification of risks and build contingency plans Well planned execution despite of having multiple dependencies

© 2012 WIPRO LTD | 10 Name: Business Goal Based Pattern Context: A North American Insurance customer initiated a project to re-architect existing applications with the intent of achieving the marketing requirement to rollout the products across states in shortened time cycle. Problem: How to devise a test strategy to meet business driven goals and objectives wherein meeting ? Test Strategy Levers What To Address?Impacts Test Process  Selection of right process to align to business goal. For example to reduced test life cycle consider agile process Removal of ineffectiveness due to process misfit. This could enable meeting of more than business objective such as:  Reduced cost  Speed to market Scope & Objective  Design the test process, methodology focusing on business objectives  Manage the test scope to ensure business objectives are not negatively impacted  Business objective driven execution  Well defined approach to meet the business goals and objectives Test Management  Identification of Risks and build contingency plans  Build Cost Of Quality Model (COQ) to track and measure cost of quality Well planned execution despite of having multiple dependencies

© 2012 WIPRO LTD | 11 Name: Architecture Driven Pattern Context: An Australian Insurance customer looking for re-architecting existing platform to SOA based architecture Problem: How to define a Test Strategy to meet the demands of Enterprise wide Re-Architecting of platforms and applications? Test Strategy Levers What To Address?Impacts Test Process  QA activities at early stages of Software Development Life Cycle (SDLC) to ensure design failures are detected much earlier  Well defined quality gates to ensure that critical defects are fixed Focus on defect prevention rather on defect detection Test Environment  Identify test environment requirements to execute testing both functional and non- functional for the emerging architecture  Define System Integration Test environment, staging environment, production environment Well defined test environment to test the solution which is being re- architected Test Methodology  Building test methodology to prove the new architecture meet the intended goals and objectives Effective test coverage and ensuring quality

© 2012 WIPRO LTD | 12 Name: Migration Based Test Strategy Pattern Context: One of the American Insurance Organization defined a strategic roadmap to consolidate the existing platform on which solution is built and reduce the number of COTS product used for the existing solution Problem: What is the best test strategy to support strategic projects and non- strategic projects simultaneously? Test Strategy Levers What To Address?Impacts Test Management  Dynamic management of resources Address fluctuations in resources requirements Test Environment  Test Environment requirements for both non-strategic and strategic projects Effective management of test environments across project tracks Test Methodology  Identify types of testing required at for different project tracks  Well defined scope of testing Optimizes test execution effort

© 2012 WIPRO LTD | 13 Name: Transition Based Test Strategy Pattern Context: Europe based Insurance Organization having multiple development partners who are also performing testing of the solution which they own. This resulted in major quality related issues. Problem: How to ensure successful completion of transition in an effective manner & perform Independent Verification & Validation? Test Strategy Levers What To Address?Impacts Test OrganizationQA governance structure to drive Quality requirements to be met across projects owned by different vendors Effective management of Quality Assurance Test MethodologyTo drive quality of products developed by 3 rd party vendors Quality Assurance Test ExecutionFast track test execution by completing the transition at the earliest Effectiveness of execution Defect ManagementPerform defect triages to prioritize defect fixes Avoids suspensions of test execution due to pending defect fixes Test ProcessFocus on aligning the test process to development life cycle adopted by 3 rd party vendors Brings process consistency across development life cycle

© 2012 WIPRO LTD | 14 Name: Multi Rollout Based Pattern Context: One of the Insurance Organization which has presence across geographies such as Latin American Countries, Asia Pacific, Europe and North American regions plan to setup centralized QA function to support releases across geographies Problem: How to address multiple releases across the geographies? Test Strategy Levers What To Address?Impacts Test Processstandardize the process across geographies Better control Quality Assurance Test Methodologystandardize the test methodology across geographies Better control over test execution Test Environment  Management of multiple test environment  Standardization of tools usage Availability of test environment for test execution Test OrganizationDefine effective operations modelBetter Governance Resource ManagementEnsure availability resources on need basis including people Test execution Test ManagementWhile driving test related activities independently across geographies bring in centralized control over testing Consistency and effective management of testing
