2 TIK Mahasiswa akan dapat menjelaskan dua macam metoda yang dapat digunakan untuk melakukan penilaian dan analisa terhadap resiko kualitas. (C2) TIK-10 Mahasiswa dapat menerangkan pengelompokan tahap-tahap proses pelaksanaan pengujian. (C2) TIK-11 Mahasiswa dapat menyebutkan faktor-faktor yang harus diperhatikan untuk mengestimasi sumber daya dan anggaran yang diperlukan. (C1) TIK-12 Mahasiswa dapat menjelaskan relasi antara jadwal, sumber daya, anggaran, dan faktor kualitas dalam perencanaan pengujian. (C2) TIK-13 Bina Nusantara

3 Penilaian dan Analisa Resiko Kualitas
Bina Nusantara

4 Resiko Kualitas Bug/Kesalahan yang mungkin terjadi disebut sebagai resiko kualitas (quality risk). Gejala yang ditimbulkan oleh bug yang dapat dirasakan disebut mode kesalahan (failure mode). Ada dua metode yang dapat digunakan untuk melakukan penilaian dan analisa terhadap resiko kualitas: (1) Metoda Informal; dan (2) Metoda Formal. Bina Nusantara

5 Informal Risks Analysis Techniques
Goals: Address as many of quality risks as possible, developing tests in an order consistent with customer priorities. Breaking down the test process into the classic phases of component testing, integration testing and system testing Bina Nusantara

6 Component Testing States Transactions Code Coverage Data Flow Coverage
Functionality User Interface Mechanical Life Signal Quality Bina Nusantara

7 Integration Testing Component or subsystem interface Functionality
Capacity and volume Error / Disaster Handling and recovery Data Quality Performance User Interface Bina Nusantara

8 System and Acceptance Testing
Functionality User Interface Operations Capacity and Volume Reliability, Availability, and stability Error/disaster handling and recovery Stress Performance Date and Time Handling Localization Network and Distributed environments Configuration option and compatibility Standard compliance Security Environment Power Input, consumption and output Shock, vibration and drop Installation, cut-over, setup and initial configuration Documentation and Packaging Maintainability Alpha, beta and other live tests Bina Nusantara

9 Failure Mode and Effect Analysis
A Formal Method for Understanding Quality Risks FMEA is a technique for understanding and prioritizing possible failure modes (or quality risks) in system functions, features, attributes, behaviors, components and interfaces Bina Nusantara
