Quality Management

16 04 2015

Have you ever heard of

Never change a running system.

The saying, it is presumed, (awkwardly) comes from German IT-experts. What they mean is:

If it ain’t broken, don’t fix it.

In my humble opinion companies or people following this belief are doomed.
Why? Because just like cars, IT systems need regular service and maintenance in order to run smoothly over a long period of time. Hardware components usually either fail right from the start or at the end of their lifecycle. Operating systems as well as apps are faced with different hard- and software configurations, and so they need updates.

The Bathtub Curve

  • 1 decreasing failure rate
    known as early failures
  • 2 constant failure rate
    known as random failures
  • 3 increasing failure rate
    known as wear-out failures

applied to IT systems, shows us:

The older a system gets (I’m talking about my iPhone 4S), the more likely its failure becomes. In addition to that you have to take into account that over time hardware spare parts might become scarce and vendor support for software might run out.

So instead of relying on your battle-proven system running for years without incident and change, you should regularly patch and update. Of course this bares risks because there are lots of developers who do a pretty poor job when it comes to concentrate on writing fault-tolerant, robust code and intensive testing. Testing is what developers definitely don’t like. The UI should be as simple as possible but the underlying code then is most likely quite complex.

Quality Management means …

Get your enemies on board.

Their single target is always to let your developments crash.

Apple has rigorous testing policies regarding hardware products. The lab in Cupertino contains an array of different testing equipment. Apple’s head of engineering Dan Riccio said:

As we add more and more features, we have to find out a way to break them before customers do.

According to Apple, 15,000 separate tests were conducted on both the iPhone 6 and the iPhone 6 Plus.

This fussy approach is what I actually miss if it comes to iOS, Apple’s mobile operating system.

It’s not as fault-tolerant as the predecessors and developers seem to have their problems with keeping their apps to run with an acceptable stability. Sometimes it’s nerve-racking.

Troubleshooting …

If your mobile device causes trouble there are just a few possibilities to fix problems: restart, restore, and recovery. There is no need to read tons of knowledge base articles, thankfully.

I don’t want to install dubious third-party apps on a computer (which I do not have because I already moved into the Post-PC era), so, dear Apple developers, I would like to see a revamped backup/restore procedure which allows the restore single apps and its data. Apple’s ecosystem is nearly perfect but it definitely lacks with the iTunes dinosaur and the atavistic backup/restore procedure.

Anyway,

at the end of the day, steady maintenance is much less of a hassle than standing next to your broke car on the highway not knowing if you will ever get it to work again.

Mobile Device Testing …

The devices are small but the effort to test them is higher than that of a grown-up computer. Smartphones and tablets have lots of micro machines on board and the operating system has to seamlessly communicate with them.

Mobile Device Testing assures the quality of mobile devices, like mobile phones, tablets, etc.

The testing will be conducted on both hardware and software. And from the view of different procedures, the testing comprises R&D testing, factory testing and certificate testing.

Mobile Device Testing involves a set of activities from monitoring and trouble shooting mobile application, content and services on real handsets. Testing includes verification and validation of hardware devices and software applications.

See the visualized summary of mobile device testing in this mind map:

Advantage Apple …

It’s all about fragmentation.

2015/01/img_3791.png

Developing applications for the Android platform is a complicated business. You have to test with multiple operating system versions, hardware vendor interface layers, hardware configurations, and network capabilities. The testing matrix for Android-based applications can be a serious challenge, impacting your product’s quality, time-to-market, and in the end, profitability.

Apples and Droids

9 04 2015

Everyone is entitled to create a community on Google+.
At the time there are about 50k communities with memberships ranging from 1 to more than 500k. It’s obvious that we also see many communities dedicated to the brand Android as well as those dedicated to Apple. This incites platform wars and trolling is a daily business for many members. This area of life often is called FANBOYISM.

The scientific background …

The Internet changed the way people argue and communicate with each other. Usually this happens between men, because men will defend their ego no matter how slight the insult is. These are also usually about geeky things that cost lots of money, because these battles take place on the Internet where tech-savvy people get rowdy, and the more expensive a purchase, the greater the loyalty to it.

/home/wpcom/public_html/wp-content/blogs.dir/522/41175131/files/2015/01/img_3729.png

A phone might not seem to be something worth fighting over, but what it stands for most definitely is.

A fanboy immediately turns into a hostage. Hostages have no choice but to buy certain products.

They are far less likely to care if one device is better than another. It’s the choosing one thing over another which leads to narratives about why you did it. If you have to rationalize why you bought a luxury item, you will probably find ways to see how it fits in with your self-image.

To combat postdecisional dissonance, the feeling you have committed to one option when the other option may have been better, you make yourself feel justified in what you selected to lower the anxiety brought on by questioning yourself.

All of this forms a giant neurological cluster of associations, emotions, details of self-image and biases around the things you own.

This is why all over the Internet there are people in word fights over video games and sports teams, cell phones and TV shows. The Internet provides a fertile breeding ground for this sort of behavior to flourish.

Summary …

The imagination is that you prefer the things you own over the things you don’t because you made rational choices when you bought them.
But the reality is that you prefer the things you own because you rationalize your past choices to protect your sense of self.

Happy Birthday iPad

3 04 2015

A shining example for disruptive technology.

I’m talking about the iPad launched on April 3, 2010 designed by Apple in California and assembled by Foxconn in China.

It’s easy to forget that people once marveled at the interactive tablets carried around by characters in Gene Roddenberry’s Star Trek, or the touch screens in Spielberg’s Minority Report – dream futures that have become reality. In 1983 Apple co-founder Steve Jobs stated that his ultimate ambition was

to put an incredibly great computer in a book that you can carry around with you and learn how to use in 20 minutes…

That vision would take him 27 years to realize and after the first launch even orangutans in the Smithsonian National Zoo have worked out how to use this new category of portable devices and part of the e-loot of many human beings.

  

Apple’s way through all areas of life started in 2007 with the iPhone and got a significant improvement with the release of the iPad in 2010. This all was made possible by a large number of excellent scientists and engineers who developed the touch screen which today serves as a basis for a new style of connecting people with each other and more.

The iPad became a transformative tool in education as it can house all resources (books, readings, video, audio), connects to the internet for doing research, provides a vehicle for maintaining communication, replaces ‘dead tree’ paper versions of resources and does it all in an easy to carry around, quick starting, and simple interface.

The triumphal march of the tablet through people of all ages is because a touchscreen is much nearer to human activities than any other device or textbook can be. 

What we do is mostly what we do with our hands.

It’s our first approach to new things. Creating artworks, modeling new devices or writing down all the ideas leading to the E=m c c equation on a sheet of paper while walking through the room and reflecting our thoughts is almost always done by hand.

Apple SWOT Analysis

31 03 2015

Here is my revamped version of Apple’s SWOT including some groundbreaking decisions and engagements of the company in 2014.

The deal with China Mobile, iOS in the car, engagement in mobile payment systems with  Pay, development of disrupting technology with wearables, and the cooperation with IBM are essential parts of the strategy powered by Tim Cook and his excellent engineers.

After Steve Jobs’ death many publishing media rumored that Apple’s power of innovation would be over. But we must not forget that it was not only Steve Jobs who did the work before 2011. Thousands of highly qualified employees went along with him and still go along with Tim Cook.

Andrew Taylor, Boston Consulting Group, wrote …

Companies that continually create value over the long term a meaning decades or more, learn how to ingrain the ability into their corporate makeup; it becomes part of their culture and DNA. They create value, jobs, and growth because of their ability to institutionalize innovation.

A SWOT analysis is used to evaluate the Strengths, Weaknesses, Opportunities, and Threats in a business venture. It’s used in any decision-making situation when a desired end-state has been defined.

/home/wpcom/public_html/wp-content/blogs.dir/522/41175131/files/2014/12/img_3701.png

SWOTs may look completely different if created from external or involved people.

Annotations …

‘Vendor Lock-In’ is mentioned by some analysts but I have a quite different opinion. Nearly all other tech companies try to link their customers to their ecosystems as well.

And here is an interesting suggestion made by Michael Lapham in the comment section of my post on Google+:

If you are going to add Decreasing market share as a weakness then I suggest you add Customer demographic as a strength. Much of the market share decrease is from the entry level market while Apple continues to dominate where individuals have higher income and more education.

Tim Cook about privacy

26 03 2015

An open letter from Tim Cook, CEO at Apple Inc. since August 24, 2011, regarding Apple products, services and beliefs …

At Apple, your trust means everything to us. That’s why we respect your privacy and protect it with strong encryption, plus strict policies that govern how all data is handled.

Security and privacy are fundamental to the design of all our hardware, software, and services, including iCloud and new services like Apple Pay.

And we continue to make improvements. Two-step verification, which we encourage all our customers to use, in addition to protecting your Apple ID account information, now also protects all of the data you store and keep up to date with iCloud.
We believe in telling you up front exactly what’s going to happen to your personal information and asking for your permission before you share it with us. And if you change your mind later, we make it easy to stop sharing with us. Every Apple product is designed around those principles. When we do ask to use your data, it’s to provide you with a better user experience.

We’re publishing this website to explain how we handle your personal information, what we do and don’t collect, and why. We’re going to make sure you get updates here about privacy at Apple at least once a year and whenever there are significant changes to our policies.

A few years ago, users of Internet services began to realize that when an online service is free, you’re not the customer. You’re the product.

But at Apple, we believe a great customer experience shouldn’t come at the expense of your privacy. Our business model is very straightforward: We sell great products.

We don’t build a profile based on your email content or web browsing habits to sell to advertisers. We don’t “monetize” the information you store on your iPhone or in iCloud. And we don’t read your email or your messages to get information to market to you.

IMG_3625.PNG

Our software and services are designed to make our devices better. Plain and simple.

One very small part of our business does serve advertisers, and that’s iAd. We built an advertising network because some app developers depend on that business model, and we want to support them as well as a free iTunes Radio service. iAd sticks to the same privacy policy that applies to every other Apple product. It doesn’t get data from Health and HomeKit, Maps, Siri, iMessage, your call history, or any iCloud service like Contacts or Mail, and you can always just opt out altogether.

Finally, I want to be absolutely clear that we have never worked with any government agency from any country to create a backdoor in any of our products or services. We have also never allowed access to our servers. And we never will.

Our commitment to protecting your privacy comes from a deep respect for our customers. We know that your trust doesn’t come easy. That’s why we have and always will work as hard as we can to earn and keep it.

Tim
September 2014

Thanks for a remarkable statement.

Summary …

I cannot validate any of Tim’s statements. It needs technicians to look at the details. But what I know is that there is no evidence to not trust in Tim’s announcement.

iOS in the car

20 03 2015

or

The Good, the Bad, and the Ugly

This can happen if a high-tech car (a brand new Audi A3 with state-of-the-art security features), an iPhone (a generally disturbing factor like any other electronic device in the hands of humans), and an experienced driver (but inattentive for just a second) come together on a German Autobahn (freeway) and cause a rear-end collision with an extremely high deceleration. See the photo, does it look like a heavy impact? No, but it was horrible and fortunately the car got sidetracked because the other party drove a brand new Volkswagen designed to redirect forces.

It was on February 11, 2015 and the car (fortunately a fully insured rental car) was a total loss. The driver, it was me, still suffers from lots of bruises and a breastbone fracture caused by various airbags which opened in a jiffy to prevent the loss of an Apple fan.

You might call me a moron but you shouldn’t forget that humans frequently are as buggy as iOS 8. Shit happens Crashes happen.

Here is the recommendation for all of you based on my experience:

Your iThing is a really useful e-helper but neither an iPhone, nor an iPad, nor a Watch, nor any other iOS based feature (except navigation) should be used in a moving 4-wheel mobile device.

The human brain is a processor with a single CPU (nevertheless in some way much more powerful than any 64-Bit iThing ever can be) and it’s not capable of multitasking. It either focuses on the traffic or communicates with your iThing regardless of talking to SIRI or listening to Apple’s voice assistant intensively.

Whatever Apple will tell you

“Invite more apps along for the ride.”
or
“CarPlay The best iPhone experience on four wheels.”

iOS in the car is only helpful if it’s working quietly in the background, giving you some short audio advices, or just monitors what you are doing. Users are acquainted with all the security advices but often do not act rational. That’s what vendors of infotainment systems know but ignore when advertising their products.

Some headlines showing the facts …

Thats what I found with a quick Google search:

  • Distractions caused by smartphones contribute to about 25% of U.S. automobile accidents
  • Wake-up call: Accidents linked to smartphone use rising in Tokyo
  • Some 40 million Koreans now have smartphones, and an increasing number of them are causing accidents in busy areas
  • Germany’s Autobahnen are getting more and more dangerous because of the usage of smartphones. It’s unjustifiable that e.g. Ford allows the forwarding of an SMS to the navigation display.

… and uncountable more publications.

Definitely not the right way to solve the problem is to separate the normal people from the addicts like the city of Chongqing in China reportedly did when setting up the country’s first sidewalk for ‘mobile phone addicts’, with a lane specifically dedicated to those glued to their screens.

There is just one solution.

First think wether you really need a constant incoming bit radiation.
If it’s relevant, stop before using your mobile device.

Do you know that mobiles can be powered off?

It saves lives, yours, others, and that of your battery.

Steve Jobs take …

“My kids accuse me and my wife of being fascists and overly concerned about tech, and they say that none of their friends have the same rules…
That’s because we have seen the dangers of technology firsthand.
I’ve seen it in myself, I don’t want to see that happen to my kids.”

Just adopt Steve’s belief for yourself.

Note …

The Good, the Bad, and the Ugly.

originally the title of a well-know 1966 Italian Spaghetti Western means in this context

The Audi, me, and the pain.

More than dissensions

16 03 2015

If I look back on 2 years of social networking, Androids and others often attacked me without any good reason. This let me quit my job as a moderator in an Apple related community and let me stop replying to any comments made by trolls or others. If they appear in my profile stream or in the comment section of my community posts, I simply delete them and block the guys who definitely show personality traits that fall in the so-called Dark Triad.

IMG_3654.PNG

The worrisome result of scientific researches about fanboyism is described in an article of Chris Mooney on SLATE com. You will find the results in my blogpost Fanboyism.

Even though a G+ membership is free, you sometimes have to pay a price for holding an opinion regarding mobile devices, admiring Apple and its leaders, and publishing all this on the internet. And sometimes it’s a heavy price if you are a German and faced with more than 90 year old resentments, even if you are born after the end of the NAZI terror regime.

But …

there are no evil forces standing behind my profile picture.

It’s just me, an open-minded old man, engaged in social networking and sometimes telling others his very personal and subjective opinion.

What’s wrong with that?

With my engagement here on G+ I just want to connect to people all over the world regardless of color, religion, age, sex, and political orientation as long as etiquettes are maintained.
