7 Test Architect Some external references (2) ISTQB Glossary ( Test architect (1) A person who provides guidance and strategic direction for a test organization and for its relationship with other disciplines. (2) A person who defines the way testing is structured for a given system, including topics such as test tools and test data management. That s ok but there is more Page 7

10 As a Test Architect You have one Role but you are wearing two Hats Test Expert for the system under test (SUT) Design the test approach Apply innovative test technologies Drive the quality of the SUT Software / System Architect for the test system Design and realize the test architecture Apply innovative software technologies Drive the quality of the test system This is the architect's job!

11 The Test Architect as a technical communication hub Page 11 Customer, Portfolio/Product Manager (Sub) Project manager Supplier Manager Quality Manager / Quality Engineer, Regulation experts Safety, Security, EMC, experts Line Manager System/Software Architect Test Engineer Maintenance -, Service -, Repair -, Refurbishment experts Commissioning, Production, Operation experts Designers, Developers, Engineers Test Manager System Integrator Q-related Roles To interact & motivate efficiently is crucial for Test Architects Close Communication Loose Communication

12 A Test Architect needs a broad set of competencies Business Understanding Testing and Quality Business model Ecosystems, understanding Partnering, Suppliers Standards, Regulations, Legal issues Global development Lifecycle issues Expert Development processes Domain knowledge Test & Quality management Advanced Product & System requirements Test automation Basic Quality requirements Requirements Engineering Expert drives, coaches and is able to improve in own domain & scope Page 12 Basic Advanced knows about can apply Test strategy Test architecture Design for Testability Test methods & technologies Lean & Agile testing Test process improvement Testing Governance & Guidance Arch. & Design Architecture Quality Project management Social skills Leadership TeA TeM Architecture and Development Integration & Deployment Social Skills & Leadership Test Architect Test Manager

13 Test Architect Role profile Responsibilities and tasks (extract) Business Understanding Analyze the current testing process and practices and drive improvements Evaluate and select technologies (e.g. by prototyping) Provide detailed planning information for testing-related tasks (esp. w.r.t. testing of requirements and testing infrastructure) Identify and manage technical product risks Setup supplier agreements for outsourced testing infrastructure development Define acceptance criteria for outsourced product development Perform make-or-buy decisions Requirements Engineering Architecture and Design Testing & Quality Maintenance Business Understanding Ensure testability of requirements engineering artifacts Define testability requirements Foster the use of test-driven approaches in requirements engineering Enforce traceability in testing artifacts Prioritize requirements Page 13 black: responsible, grey: involved Requirements Engineering

14 Test Architect Role profile Responsibilities and tasks (extract) Business Understanding Ensure that testability requirements are incorporated into product design Create design prototypes for testing infrastructure Provide testing infrastructure requirements Define reuse strategy for testing infrastructure components Identify and manage technical risks for the testing environment Setup integration plan for the testing infrastructure Drive integration of testing infrastructure with the SUT Guide/Coach system/software architects in testing related topics Identify and implement reuse for test cases and testing infrastructure components Review architecture artifacts Requirements Engineering Architecture and Design Testing & Quality Maintenance Architecture and Design black: responsible, grey: involved Page 14

15 Test Architect Role profile Responsibilities and tasks (extract) Business Understanding Requirements Engineering Define and implement a justified, effective test strategy for the project, aligned with the business and quality goals Measure efficiency and effectiveness of the test strategy Architecture and Design Measure, control and continuously optimize coverage and degree of test automation Testing & Quality Maintenance Define and maintain an effective and efficient test architecture in close cooperation with system integration and test managers Govern the design and improvement of test automation framework and test suites Ensure quality of the test code Guide/Coach testing engineers in advanced testing issues Discuss and elaborate test aspects in early development phases Identify and manage testing stakeholders Perform impact analysis for changes in the system/software Monitor and improve the system/software integration process Testing & Quality black: responsible, grey: involved Page 15

16 Test Architect Role profile Responsibilities and tasks (extract) Business Understanding Perform continuous architecture management for the testing environment Manage the internal quality of the whole testing environment Provide comprehensive documentation of the testing infrastructure's architecture Establish and maintain configuration management for testing artifacts Ensure that testability requirements from post-development phases are taken into account Analyze customer feedback Requirements Engineering Architecture and Design Testing & Quality Maintenance Maintenance black: responsible, grey: involved Page 16

21 Scope of Internal Quality As a Test Architect You have one Role but you are wearing two Hats Test Expert for the system under test (SUT) Design the test approach Apply innovative test technologies Drive the quality of the SUT Software / System Architect for the test system Design and realize the test architecture Apply innovative software technologies Drive the quality of the test system This is the architect's job! Internal Quality of the SUT (production code) Page 21 Internal Quality of the test system (test code)

22 Summary Test Architect A new key role Test Architect on eye level with software / system architects Diverse responsibilities and tasks that require proper skills, competencies, capabilities A new career path for testers A good Test Architect provides value and creates impact on the business Page 22
