- 12. Otto pilots
- 13. Is there a pilot in the plane? 1996 Pitot Tube…blocked by a wasp - 189 people died 2011 Pitot tube malfunction (iced?) Air France Rio-Paris 228 died Nose up though loose lift
- 14. GPS 2012 - Apple Maps 'is life-threatening' to motorists lost in Australia heat - 24 hours with no water supply - 46°C outside - Mildura located 70 km away from its actual location - GPS software is also vulnerable - Apple used Google Maps later on
- 15. Now Now or neve
- 16. The development challenges • Agility From planning to value • Shorter / iterative cycles • Business – Development Development – Production • Continuous integration Continuous testing Continuous delivery • Mobile / Embedded / IOT • Disposable APPS? Multiple releases / day Saas / S’aaS (service as a service)
- 17. The time challenge – now, now Too slow I’d better go shopping in the mall next door Hmm! That looks better, but still…
- 18. Fast and faster Hmm that’s fast but you can do better Yes, we can! Let’s see what we can get on you
- 19. Minority Report e-commerce Wow! This would really match my… I need it NOW We know what you did last summer We know what you all did last summer Let’s ship your next wish before you make it Proximity warehouse So if you really order it … You get delivered in no time…thank you who?

- 30. In the heat of the night Consulting firm iiMedia Research polled 12,000 Samsung users in China on whether the Note 7 fiasco has affected their decision to stick with the company. Of them, 51.9% said they will definitely switch away from the brand when buying their next phone, 18.5% said they will consider switching, and 29.6% said the incidents do not concern them since they were caused by external factors.

- 32. Social Economy
- 33. The social economy challenge Google + Über alles Smart grids GPS, traffic control APPS
- 34. What goes social? • Crowdfunding • Crowd development • Crowd testing • Collaborative apps – Traffic / radar / navigation – Selling / buying / advising • Energy grids • Gaming • Transportation • And many more…
- 35. Demography
- 36. The demographic challenge We start using IT sooner and sooner We grow older and older
- 37. We are ageing It’s not Freddy K it is Cambridge Lab I know the date, I know the time, but I can’t pick up a call Press harder is NOT swipe
- 40. Help & Tools
- 41. The ISTQB addresses parts already And more to come
- 42. What else? • Let’s bring Business and IT together! • design analysis • market analysis • innovation • Let’s design better requirements • engineering • analysis • elicitation • Let’s get the right focus on users • usability • user experience • design
- 43. Conclusions 1 Agility and IOT will keep on spreading and developing, so as web technologies, APPS, big data and cloud services 2 Testers need to address new challenges (continuous testing, non functional testing) Some of which are yet to be identified 3 ISTQB® and other standards are there to help and guide you Be prepared and be ready to change!
- 44. I wish you all a brilliant f
Notas do Editor
- I’m very much into fooding – it’s no big secret, just look at me My mother told me « never waste good food », so when you’re done with your cooking…what do you do with leftovers? You prepare another great dish by recombining them in a different way
- But, my talk is not about food but about testing and how it might evolve – so let’s jump to this now
- IOT – sensors, controls Sensitive information – ID, access, payment Data Mobile applications
- French toast is a good way to recombine old bread, eggs and milk Oh, have you seen my cigar?
- People connect with different devices, different versions, different APPS, diffreent form-factors They need to do everything at any moment It has to be usable (they need to understand) and social (social approval, image) or the throw it away It has to be secure and performing well (connectivity, network) on each and every channel

- 1996 Birgenair - https://en.wikipedia.org/wiki/Birgenair_Flight_301 During takeoff roll at 11:42 p.m, the captain found that his air speed indicator (ASI) was not working properly, but chose not to abort takeoff.[6] The co-pilot's ASI was functional. While the plane was climbing through 4,700 feet (1,400 m), the captain's airspeed indicator read 350 knots (650 km/h). The autopilot, which was taking its air speed information from the same equipment that was providing faulty readings to the captain's ASI, increased the pitch-up attitude and reduced power to lower the plane's airspeed. The co-pilot's ASI read 200 knots (370 km/h) and decreasing, yet the aircraft started to give multiple contradictory warnings that it was flying too fast, including rudder ratio, Mach airspeed, and overspeed lights and sounds. The autopilot reached the limits of its programming and disengaged. After checking their circuit breakers for the source of the warnings, the crew then reduced thrust to lower the speed. This immediately triggered the 757's stick-shaker stall alert, warning the confused pilots that the aircraft was flying dangerously slow, seconds after it was warning them that the speed was too high. The co-pilot and the relief pilot Muhlis Evrenesoğlu both seemed to recognise the approaching stall and tried to tell the captain, but did not intervene directly, possibly out of deference to the captain's age and experience. The captain then tried to recover from the stall by increasing the plane's thrust to full, but the plane was still in a nose up attitude, preventing the engines from receiving adequate airflow to match the increase in thrust. The left engine flamed out, which caused the right engine, still at full power, to throw the aircraft into a spin. Moments later, the plane inverted.[7] At 11:47 p.m., the Ground Proximity Warning System sounded an audio warning, and eight seconds later the plane crashed into the Atlantic Ocean. All 13 crew members and 176 passengers were killed. Rio-Paris Having departed from Rio de Janeiro bound for Paris, the co-pilots encountered trouble with the speed sensors four hours and 10 minutes into the flight. The flight was on autopilot as the pilot in command took a routine rest out of the cockpit. They were knowingly headed into a turbulent and storm-ridden spot over the Atlantic, and the black boxes show the pilots attempted to maneuver around the storm slightly. It was at this point, after autopilot turned off and they worked to change their course, that a stall warning sounded, meaning that the airplane wasn’t generating enough lift. The report notes the co-pilot grabbed the controls and lifted the plane, which, according to aviation experts is contrary to normal procedure during a stall, when the nose should in fact be lowered. During the lift, the speed sensors plunged then spiked in an apparent malfunction, the report shows. “So, we’ve lost the speeds,” the co-pilot noted. For nearly a minute, as the speed sensors jumped, the pilot was not present in the cockpit. By the time the pilot returned, the plane had started to fall at 10,000 feet per minute while violently rolling from side to side. But the BEA notes the crew acted in accordance with all procedures, frantically attempting to command the plane as it pitched and rolled in the sky. The plane’s speed sensors never regained normal functionality as the plane began its three-and-a-half minute freefall. The report shows the flight remained stalled throughout the drop, with its nose pointed up 15 degrees in response to the pilots’ attempt to generate lift. The flight plunged into the Atlantic nose-up, killing all 228 on board.
