The rogue robot cost the company $440 million to ‘trade out’ of its entire erroneous trade position, as it saw its own stocks plummet.
- 8. 8 8 What are thecommon software quality issues? • Software does not fulfill user nor business expectations. • Bad requirements • Software has security issues. • Software is not stable. • Software is difficult to use • Response times soar under heavy loads. • Software changes are costly. • Software can also have “toxic assets”
- 9. 9 9 Why measure softwarequality?
- 10. 10 What is softwarequality in the broader sense? Quality = Testing + … not only testing. o The # of functional defects is a quality indicator but not the only one o Wider angle approach: verify the compliance with standards and normatives, avoid common coding and configuration , detect design anti-patterns defects, make software easier to maintain, and in general technically measure other characteristics (efficiency, portability, security, reliability…)
- 11. 11 11 How much doessoftware quality cost? The PAF* model: More prevention, less failure, improve Defect Removal Efficiency Find the quality level to minimize Cost of Quality •
- 12. 12 What can youdo about it? • The goal is reach your required levels of quality balancing the cost with the savings you will get by having those quality levels. • This will yield to a high Defect Removal Efficiency (DRE) and reduce total cost. • Focusing only in 3 possible quality assurance techniques: Static Code analysis, Peer Reviews and Testing (functional mostly) • A combination of the 3 of them implies a best overall cost scenario: 33% more cost efficient than only doing testing.
- 13. 13 How can youdo it? • Integrate all quality assurance practices in your SDLC. • Automate Static Code Analysis to have a continuous analysis and measurement process. It is the only way to detect and remove code defects as early as possible. • Use static analysis information to make your peer review process more efficient • Automate testing as much as you can.
