20 G.Bath 5.6 Adapting toDifferent Lifecycle Approaches A tester must have competencies in working with different lifecycle models, includingsequential (e.g.V-Model)and iterative (e.g.agile). Competencies requiredof theNG Tester: • Place testingactivitieswithin theparticular lifecyclemodel. • Applycommunicationandautomationcompetenciesas requiredby the lifecycle model. Summaryof theGeneralCompetences TheNGTester can: • Practice theessentialsof testing inorder todetectdefectsearly • Apply risk-based testing toprioritize testing • Understanddifferentsystem architectures inorder toestablish testingneeds • Communicateeffectively in teams • Communicatewith stakeholdersat their level • Judgehowmuchcommunicationis enough • Achieveefficienciesbyusing test automation tools • Programtest automationscriptswhicharemaintainableandefficient • Place testingactivitieswithin theparticular lifecyclemodel • Applycommunicationandautomationcompetenciesas requiredby the lifecycle model 6 SpecialistCompetencies A wide spectrum of different specialist competencies may be acquired by the professional tester.
