How Software Issues in Cars Cost Automakers Billions [Infographic]

Code complexity has reached new levels with more than 100 million lines of code in a single automobile.  Due to the massive amount of code that is being introduced to vehicles, understanding the software and its quality has never been more important.  The recent discovery of Volkswagen’s “Defeat Device” sparked an investigation into other car manufactures processes and emissions claims.  During the process, there were a number of news worthy findings.  We now know that Volkswagen isn’t the only manufacturer that is not meeting emissions targets.
Over the past 10 years, almost every major car company has had recalls due to software issues. Although none have been as news worthy as the recent Volkswagen findings .  Toyota was also investigated when it was found that their vehicles were unintentionally accelerating.

Insights into the Internet of Things

IoT Makes “As Good as the Day I Bought It” a Thing of the Past

By Jim Brown Published on October 26, 2015

A recent Harvard Business Review article, How Smart, Connected Products Are Transforming Companies, shares insights on the way today’s intelligent, sensored products and the Internet of Things are changing the fabric of manufacturing companies. One particular area that caught my eye is the discussion on “Evergreen Design.” As the article points out, “Smart, connected products … can be continually upgraded via software, often remotely.”

The article shared two examples that, to me, explain why manufacturers need to pay attention to this discipline. In two separate instances, Tesla set themselves apart from traditional automakers using evergreen principles. In the first, they identified a hazardous driving condition that was leading to fires and remotely upgraded all existing cars’ suspensions to prevent the scenario from occurring. They made the car safer to drive and avoided an expensive recall. In another, they included “autopilot” capabilities into cars while the feature was still a work in progress. They avoided the difficult, traditional tradeoff of either omitting a new feature in a new model or delaying product introduction. They included what they could with plans to continually improve it and introduce the feature when it was ready.

So why should manufacturers pay attention to evergreen design? Let’s step back a bit.

Remember when the day you bought a product was the best it would ever be? With the exception of a few anomalies like blue jeans or a baseball glove that getter better with use, the brand new product was at its best. Then, after a while it slowed down, got weaker, wasn’t as responsive, would stop doing a function, or maybe a part broke off. Performance and features declined with time. The best you could possibly hope for was “as good as the day I got it.” Maybe your products are still that way.

But I distinctly remember the day that changed for me. I upgraded my BlackBerry to a new operating system and it turned into a brand-new and improved device! The user interface was much more graphical. I was giddy. It was like a new phone for free!  The way of the future for equipment has started to look a lot more like an upgradeable computer instead of a piece of equipment that could only deteriorate over time. The smarter devices have become, the more they can improve, evolve, and gain value as you own them.

But the real reason manufacturers have to pay attention to evergreen concepts is that it fundamentally changes the relationship between a manufacturer, the products they make, and the customers that use them.

The more connected products have become, the more engaged the manufacturer (or service provider) can stay in the product while it’s in the customers’ hands. This is why smart, connected products should be viewed as a major disruption as opposed to a simple step change in product capabilities. Now manufacturers can offer new services, like adding live traffic information or restaurant reviews to a GPS.  They can fix problems with devices before customers know they exist. They can leverage new design practices like soft buttons and controls that allow them to add new interfaces and functions to products in the field that the original designer may not have been able to anticipate.  They allow the manufacturer to experience what customers are doing with products in the field to gain new insights.

Let’s not celebrate this brave new world too quickly, though. There are plenty of obstacles for manufacturers to address.

I also remember the first device that “bricked” on me. I downloaded a new operating system and my phone downgraded itself into a paperweight. In that case, permanently. I also remember the fist time my car bricked on me. A sensor mistakenly determined that some mechanical parts were going to clash so it shut the motor off leaving my family stranded at a kid’s baseball game. That was a wakeup call on the potential pitfalls of smarter products.

The point is, designing smart products is hard. The industry has started to make strides in developing and validating “mechatronic” products that contain mechanical, electrical, and software components. But evergreen design takes advantage of smart products (systems) connected to other systems. It leverages connectivity to data sources in the cloud. It relies on feedback from devices to get to the manufacturer and make a round trip with updates. And it all has to work together. That’s a lot to design and validate. It’s even more difficult to manage as things change!  If manufacturers push updates to products running in the field, they have to be able to simulate and validate their behavior to avoid turning a potential positive upgrade into unplanned downtime.

The industry still has a lot to learn about how to effectively develop systems, and now we are pushing the boundaries further. Why? Because the value is there. Products can now get better over time. The relationship between the manufacturer and the user can be closer. That’s simply too compelling of an opportunity. The complexity has to be – and will be – met by new design disciplines and tools. Now, maybe we will love our old equipment as much as we love our old blue jeans and baseball gloves.

This is the second installment in a series of guest posts by leading industry analysts covering topics found in the new Harvard Business Review article, How Smart Connected Products are Transforming Companies, co-authored by PTC CEO, Jim Heppelmann, and Harvard Business School professor, Michael Porter.

    San Francisco Now Has Its Own Cellular Network Just For The 'Internet Of Things'

    Aaron Tilley ,

    Forbes Staff

    I cover hardware and chipmakers.

    Full Bio

    Does your fitness tracker need its own cellular network? Sigfox think so.

    Phone carriers like AT&T T +0.00% and Verizon love talking about the “Internet of Things” — the tech industry’s buzzword for the hooking the entire physical world up to the internet. But adding a conventional cellular modem is going to suck up a lot of power, and these kinds of devices need a low power way of connecting to the internet.

    Sigfox’s answer is a wireless network that specializes in communicating with millions of low-power devices that don’t deal with large streams of data. The Toulouse, France-based company’s network is already covering almost all of France and Spain.

    Now Sigfox is pushing hard into the US. At an event on Tuesday, the company is announcing it has complete coverage of San Francisco, and is planning coverage for a total of 10 US cities by the first quarter of 2016: San Francisco, New York, Boston, Los Angeles, Chicago, Austin, Houston, Atlanta, Dallas and San Jose. Allen Proithis, a former HP executive, is leading this US rollout as Sigfox’s president of North America and the regional headquarters will be based in Boston.

    For the San Francisco rollout, Sigfox has around 20 of its briefcase-sized base stations on the top of buildings around the city. It partnered with the city of San Francisco to reserve space on these buildings.

    Sigfox’s network is able to handle tiny packets of data. These are small 12-byte messages — not enough for streaming video. Instead of phones, Sigfox’s wireless network is tailored for everything else you might want to hook up to the internet: parking meters, fire alarms, moisture sensors out in a farm field, or even wearables. In Europe, for example, Swedish security giant Securitas has built home security monitoring products that hook up to the Sigfox network. For the initial US rollout, smart electricity meter maker Glen Canyon is announcing that it will use the Sigfox network.

    Building out Sigfox’s wireless network infrastructure is a lot less costly than putting together a phone network, the company said. The network runs on the unlicensed wireless spectrum band of 900 megahertz in the US, so the company doesn’t need to acquire licensed spectrum. For a geographical location like the size of the entire state of California, Sigfox estimates it only needs around 1,500 microcells compared to something like 20,000 for a traditional cellular network, said Thomas Nicholls, the executive vice president of communication at Sigfox, in an interview with Forbes in July.  It took only 12 months to get its network to cover all of Spain, Nicholls said. The company partners with existing cell tower owners and uses off-the-shelf hardware. Once the company achieves scale in a region, the idea is to provide a subscription for access to the Sigfox network for around $1 a year per device.

    For device makers, they have to install a radio chip that costs less than $2 and comes loaded with the Sigfox firmware. Chip vendors such as Texas Instruments TXN -1.75% and Silicon Laboratories are selling these Sigfox chips. Samsung, an investor in the company, is also starting to build Sigfox connectivity into its Artik chips, which are designed for low-powered devices in the Internet of Things market.

    Samsung, along with chipmaker Intel INTC +0.00% and Spanish telecom Telefónica, have poured more than $150 million into the company.

    Although traditional mobile network operators are also going after the growing market around the Internet of Things, Sigfox sees opportunities to partner with them. For example, AT&T is switching off its 2G network by the end of 2016, but there are still many devices running on it. AT&T could partner with Sigfox to pick up those connections. Said Sigfox’s Proithis, “US carriers are still trying to figure us out.”

    IoT: The Success Tool for Entrepreneurs

    If you are in the startup space , or are someone who keenly follows technology news, IoT is an acronym that you hear very often.
    IoT means Internet of Things, and it is the network of physical objects which are embedded with electronics, software, network connectivity, and sensors which enable these objects to exchange data . It should be noted that IoT and data are mutually inclusive here, one cannot add value without the other.

    HoloLens Event Tour for Developers

    Yesterday, I had the privilege of showing HoloLens to developers in Chicago. I was really impressed with the ability of the HoloLens device. These are pre-production devices but they worked really well. If you were wondering if the videos you have seen really work that way – I can tell you they do. The customers, I talked with yesterday, had a lot of great ideas on what they want to use this device for to support their businesses. From training simulators to education tools and of course games.
    Yesterday, I played a demonstration game with the HoloLens. It showcased the Windows Holographic Platform and the features it offers. It was really cool and is the start of something that will transform the world in the same way other technologies have. Technologies such as electricity, the gas engine, Television, or cellphones. Reality augmenting holograms have the promise to make this type of change to the world. A change which is surreal when it first launches but then becomes something you don’t know how people lived without.

    So, how do you make money in IoT?

    So, how do you make money in IoT?

    A recent InfoWorld article proclaims "The Internet of Things is not paying the rent." In it, Adobe's VP of Mobile Matt Asay cites data from VisionMobile and McKinsey & Co. to point out that "less than 10 percent of IoT developers are making enough to support a reasonably sized team," and that "developers need to get real about what they're selling and to whom," which "probably involves a 'dull' enterprise-facing business." This begs the question, how do you make money in the IoT?

    In a column last year on hardware commoditization I discussed the idea of "IoT-as-a-Service," wherein Internet of Things companies could potentially transition away from one-off IoT platform sales and into business models that allow for accretive growth by means of data and feature . In this cloud-based approach, companies could establish service plans or provide additional features to end users similar to how your cell phone or cable company operate, generating recurring streams of income that continue to flow after the initial platform sale (or perhaps, giveaway) to help offset ongoing maintenance, service, and support costs. Furthermore, this paradigm permits a new way of thinking about the product development lifecycle, as rather than offering a portfolio of hardware platforms each with different features engineered into individual SKUs, can be utilized to enhance or reduce functionality on a given platform (or set of platforms) by turning capabilities on or off.

    However, one setback of this model is that it relies on services and licensing fees as the primary source of revenue generation. With the Internet breeding a generation of developers and consumers that expect things for free or nearly free, how do you ensure ROI? In addition, while the smartphone, cable, and utilities markets have matured to the point where providers can afford front-end revenue hits on hardware in lieu of lucrative service payouts over time, in the fledgling IoT it's hard to rely on commitments to long- or even short-term commitments at the expense of a large upfront payday. Especially if you're a small IoT startup, asking a group of angel investors to risk bankrolling today's IoT devices in exchange for the uncertain promise of tomorrow's data- and software-driven dollars seems like a prayer.

    This leaves IoT developers at a crossroads, as although the increasing amount of value and a more economic approach to electronic system design is now rooted in software, capitalizing on that value has largely been restricted to traditional, hardware-centric ROI models (Figure 1).

    Management and control are key to monetizing IoT

    By its very nature, the IoT is based on the real-time or near-real-time delivery of software and services, so getting capabilities to the end user is not the issue. Rather, the problem is one of control and management – control that ensures IP can't be stolen or reverse engineered so potential users are able to take advantage of features for free, and management that facilitates the distribution of software and services in such a manner that data or feature utilization can be monitored for appropriate billing (Figure 2).

     



     

     

    Figure 2: New approaches to feature monetization should provide mechanisms for protecting IP from piracy as well as entitlement management that opens new revenue streams for IoT developers.

    In a meeting with Aurelius Wosylus, Director of Business Development at Gemalto (www.gemalto.com) earlier this summer I was introduced to the company's Sentinel Licensing Development Kit (LDK) that addresses these challenges in multiple ways. From a and IP protection perspective, the Sentinel LDK represents an evolution of Gemalto's licensing protection products into a single "Cross-Locking" technology suite that allows developers to implement a combination of hardware and/or software-based . In software, keys are exchanged using the Sentinel Envelope, a wrapper that uses code encryption at system boot up and system-level anti-debugging, among additional features, to control access to executables, libraries (DLLs), and other software data files so they can only be decrypted by authorized parties (Figure 3). Hardware-based encryption can also be utilized through technologies such as AppOnChip, which locks applications to individual devices so that specific code blocks can be authenticated at the hardware level using tokens.

     

    Figure 3: Gemalto's Sentinel Envelope, part of the Sentinel LDK, provides an encryption wrapper around products to prevent tampering and theft of valuable IP.

    Once software IP is secure, developers are able deploy software features to target devices with confidence, enabled by the Entitlement Management System (EMS) built into the Sentinel LDK. A web-based solution built on an SAP backend, the EMS allows software updates to be remotely pushed to target users and devices while also retrieving usage metrics that make flexible licensing models possible, including pay-per-use, pre-pay, and post pay. In addition, usage data can also provide insight into the behavior users exhibit when interacting with various products, which in turn can be leveraged for future R&D, marketing, and so on. Figure 4 shows an example  architecture using the Sentinel LDK and ' LabVIEW application software.

    Figure 4: The EMS features of Gemalto's Sentinel LDK permit flexible remote software licensing through reporting that can be used to support pre-pay, post-pay, and pay-per-use models.

    With control and management technologies serving as the foundation, developers can take a new approach to product definition that reduces hardware dependency and enables innovative software packaging and licensing models, many of which can provide recurring revenue streams.

    A pragmatic approach to the bottom line

    In my travels around the embedded industry the general consensus is that while consumer IoT is currently driving about 80 percent of IoT's hype, the "enterprise/industrial IoT" will amount to 80 percent of its actual value. However, nebulous projections like this don't answer the core question of how IoT companies will survive, whatever the flavor. Software monetization strategies are a big step towards getting black figures on the bottom line sooner rather than later.
