Navigating Revolutions – Book By Book

#DigitalRevolution and #4IR and many other hashtags related to “digital” are trending on social media. Because “digital” is a key concern in enterprises everywhere. We’re facing/undergoing a revolution (digital, industrial,..whatever, but “a revolution“). Digital this, digital that. And, Digital to the Core as Gartner pointed out in their book last year.

So, what to read this year? What’s on your holiday reading list? I will spend my summer reading about “revolution”. 

Did you know that Amazon has more than 150.000 books on “revolution”? So where to start? Hannah Arendt’s classic On Revolution? Or perhaps something more recent?

If you are interested in some “social reading” and want to join a study group, let’s arrange physical and/or virtual meetups! I’d be happy to host meetups – in my garden, at QualiWare in Farum, or in WebEx. So let me know if you’re interested!

My current reading list has the five books listed here below. They’re chosen because they’re recent and relevant.

Andrew Mcafee and Erik Brynjolfsson: Machine, Platform, Crowd: Harnessing the Digital Revolution

We live in strange times. Andrew McAfee and Erik Brynjolfsson know what it takes to master the digital-powered shift: we must rethink the integration of minds and machines, of products and platforms, and of the core and the crowd. The balance now favours the second element of the pair, with massive implications for how we run our companies and live our lives.

Klaus Schwab: The Fourth Industrial Revolution

We are on the brink of the Fourth Industrial Revolution. And this one will be unlike any other in human history. Characterized by new technologies fusing the physical, digital and biological worlds, the Fourth Industrial Revolution will impact all disciplines, economies and industries – and it will do so at an unprecedented rate. In The Fourth Industrial Revolution, Schwab (World Economic Forum) outlines the key technologies driving this revolution, discusses the major impacts on governments, businesses, civil society and individuals, and offers bold ideas for what can be done to shape a better future for all.

Don Tapscott and Alex Tapscott: Blockchain Revolution: How the Technology Behind Bitcoin Is Changing Money, Business and the World

Blockchain is the ingeniously simple technology that powers Bitcoin. But it is much more than that, too. It is a public ledger to which everyone has access, but which no single person controls. It allows for companies and individuals to collaborate with an unprecedented degree of trust and transparency. It is cryptographically secure, but fundamentally open. And soon it will be everywhere.

Patrick Hoverstadt and Lucy Loh: Patterns of Strategy

Patterns of Strategy shows how the strategic fit between organisations drives strategic direction. It is essential reading for those who wish to understand how to manoeuvre their organisation to change its strategic fit to their advantage. The 80 ‘patterns’ of strategy help you explore options for collaboration and competition within your strategic ecosystem. A practical and authoritative guide, you can use it to plan and navigate your strategic future.

Roger Tregear: Reimagining Management

Reimagining Management introduces the concepts of the 7Enablers of BPM and the Tregear Circles as part of a practical framework for the positive and controlled evolution of management practice; an approach to organizational management that focuses on the creation, accumulation, and delivery of value to customers and other stakeholders. Using this book as a guide, it’s time to reimagine management.

Reference Architectures for Industry 4.0

We stand on the brink of a technological revolution that will fundamentally alter the way we live, work, and relate to one another. In its scale, scope, and complexity, the transformation will be unlike anything humankind has experienced before.

On our study trip to Automation Valley, we learned about Industry 4.0 and the digitalization of German manufacturing. On the way back to Denmark, one of the other participants said, “yep, the Germans set the standard”. This is indeed the case, even in a very literal sense: They’re making Industry 4.0 a German DIN Standard, and are aiming for international standardization.

Introducing RAMI 4.0

The German Electrical and Electronic Manufacturers’ Association, and its partners, have developed the Reference Architecture Model for Industry 4.0 (RAMI 4.0). Today supported by the Plattform Industrie 4.0 network, RAMI 4.0 is held as a key standard for Industry 4.0.

RAMI 4.0_neue Farben_849x566RAMI 4.0 consists of

a three-dimensional coordinate system that describes all crucial aspects of Industrie 4.0. In this way, complex interrelations can be broken down into smaller and simpler clusters.

The coordinate system is further described as follows:

The “Hierarchy Levels” axis:

Indicated on the right horizontal axis are hierarchy levels from IEC 62264, the international standards series for enterprise IT and control systems. These hierarchy levels represent the different functionalities within factories or facilities. In order to represent the Industrie 4.0 environment, these functionalities have been expanded to include workpieces, labelled “Product”, and the connection to the Internet of Things and Services, labelled “Connected World”.

The “Life Cycle & Value Stream” axis:

The left horizontal axis represents the life cycle of facilities and products, based on IEC 62890 for life-cycle management. Furthermore, a distinction is made between “types” and “instances”. A “type” becomes an “instance” when design and prototyping have been completed and the actual product is being manufactured.

The “Layers” axis:

The six layers on the vertical axis serve to describe the decomposition of a machine into its properties structured layer by layer, i.e. the virtual mapping of a machine. Such representations originate from information and communication technology, where properties of complex systems are commonly broken down into layers.

Together, the axes form a model that can be used as follows:

Within these three axes, all crucial aspects of Industrie 4.0 can be mapped, allowing objects such as machines to be classified according to the model. Highly flexible Industrie 4.0 concepts can thus be described and implemented using RAMI 4.0. The reference architectural model allows for step-by-step migration from the present into the world of Industrie 4.0.

In essense,

…RAMI 4.0 provides a common understanding for standards and use cases….RAMI 4.0 can be regarded as a kind of 3D map of Industrie 4.0 solutions: it provides an orientation for plotting the requirements of sectors together with national and international standards in order to define and further develop Industrie 4.0. Overlapping standards and gaps can thus be identified and resolved.

RAMI 4.0 is referencing three standards:

  • IEC 62890 – Life-cycle management for systems and products used in industrial-process measurement, control and automation. Note: Under development since 2013 and not available to the public until its release, scheduled for September 2016.
  • IEC 62264 – Enterprise-control system integration.
  • IEC 61512 – Batch control.

The International Electrotechnical Commission (IEC) white paper on Factory of the Future explains further that when establishing interoperability in manufacturing environments, different dimensions of integration have to be considered:

  • Vertical integration, i.e. along the automation pyramid as defined by IEC 62264/IEC 61512. This includes factory-internal integration from sensors and actuators within machines up to ERP systems.
  • Horizontal integration, i.e. along the value chain and throughout production networks. This includes the integration of production networks on the business level as achieved by EDI-based supply chain integration, but might include more in the future, when close-to-real-time and product- or process-specific information is exchanged to increase the level of detail and quality in distributed manufacturing optimization.
  • Integration towards engineering and product/production life cycle applications (e.g. IEC 62890) in order to enable low-effort knowledge sharing and synchronization between product and service development and manufacturing environments.

Standardizing RAMI 4.0

RAMI4.0 has now been put forward for standardization in Germany as DIN SPEC 91345 – Referenzarchitekturmodell Industrie 4.0.  It often takes years for a DIN SPEC to become an official DIN Standard, but now the process has begun, and since Industry 4.0 seems to be a high priority area for DIN, they may decide to fast-track this standard.

So far, the standard is available in German language only, but should be available in English too soon. For now, the most comprehensive publications in English about RAMI 4.0 seem to be the 2016 status report and the 2015 status report.

IEC has put Industry 4.0, including RAMI, high on their agenda. In their call for their general assembly later this year, IEC outlines its future plans and strategic goals for Industry 4.0 reference models and architectures:

Developing a description of the reference models in dedicated standards. As with core models, reference models are also used in a wide variety of model solutions.

Defining reference models separately as independent standards for the purposes of simplification and avoidance of unintentional deviations, and for better understanding.

Implementing a nearly finished specification (DIN SPEC 91345 – publication planned Q2 2016) as Public Available Specification – PAS within IEC, starting with the new work item procedure in the relevant Technical Committee of the IEC.

The relevant IEC committee would probably be TC65 who also owns the three IEC standards included in DIN SPEC 91345, but there are likely many other TCs in IEC who eventually become involved with Industry 4.0. The same will many other standardization organizations and initiatives. The Technical Management Board (TMB) of the International Standard Organization (ISO) has set up a Strategic Advisory Group (SAG) on Industry 4.0/Smart Manufacturing. This SAG should cooperate closely with the International Electrotechnical Commission (IEC) and the International Telecommunication Union (ITU), and is supposed to report back by September 2016. Most of this work takes place behind closed doors, and the SAGs homepage is not very informative.

Analyzing RAMI 4.0’s roots

Categories of technical assets.

The “Life Cycle & Value Stream” axis is based on an unpublished standard, and therefore difficult to assess. The 2016 status report shed some light on this, and states that:

It was one of the main design decisions of the RAMI4.0 architecture to model type descriptions as individual assets (with own life cycles) which are independent from specific products. To highlight this fact, the assets are divided along the x-axis into “types” (type descriptions) and “instances” (specific products).

And also, that,

This is just a very rough classification but it helps to separate the development and life-cycle management of product types (product families) from the production and lifecycle management of the individual products.

The distinction between type and instance is classic in software engineering and information modeling. RAMI 4.0 maps the asset categories to the life-cycle dimension and the value stream.

Architecturally, this is an interesting approach. But someone really needs to work on the visualization and explanation of the dimension. The status report hints that the IEC 62890 standard will explain it all.

The “Hierarchy Levels” (with IEC62264) dimension is based on the classic ISA-95 which dates back to the 1990s (but is still maintained).

Purdue Reference Model (Wikipedia)

ISA notes that the purpose of ISA-95 is:

To create a standard that will define the interface between control functions and other enterprise functions based upon the Purdue Reference Model for CIM (hierarchical form) as published by ISA. The interface initially considered is the interface between levels 3 and 4 of that model. Additional interfaces will be considered, as appropriate. The goal is to reduce the risk, cost, and errors associated with implementing these interfaces. The standard must define information exchange that is robust, safe, and cost effective. The exchange mechanism must preserve the integrity of each system’s information and span of control.

The Purdue Reference Model for CIM (Computer Integrated Manufacturing) from 1989, published as ISA-95, became the de facto organizing logic for manufacturing information systems and defined that the 0-4 levels have core information systems: ERP at level 4, MES at level 3, and SCADA at level 2.

i40enhancementThe hierarchy in RAMI 4.0 is divided into two parts: products (and users) and equipment (field devices, control devices, stations, work units, enterprises and connected world).

The status report seems to acknowledge that RAMI 4.0 may not have hit the nail:

All in all, the ordering schema along the y-axis is just a presentation help for fostering an intuitive understanding of the architecture. In case the terms or aggregation steps do not fit into the respective domains, they can easily be readjusted.

The “Layers” axis

serve to describe the decomposition of a machine into its properties structured layer by layer, i.e. the virtual mapping of a machine. Such representations originate from information and communication technology, where properties of complex systems are commonly broken down into layers.

Layering is a classic theme in enterprise architecture. Although there are some critics, most current enterprise architecture frameworks use architectural layers (e.g., strategy, business, information, applications, infrastructure, and security in EA3).

“The nice thing about standards …”

“…is that you have so many to choose from,” Tanembaum‘s old “joke” about standardization, applies here: RAMI 4.0 is not the only standard for digital industry reference architecture.

The major other standard is the Industrial Internet Reference Architecture (IIRA) from the Industrial Internet Consortium, which is

IICthe open membership, international not-for-profit consortium that is setting the architectural framework and direction for the Industrial Internet. Founded by AT&T, Cisco, GE, IBM and Intel in March 2014, the consortium’s mission is to coordinate vast ecosystem initiatives to connect and integrate objects with people, processes and data using common architectures, interoperability and open standards.

IIC is established by the Object Management Group (OMG). Many architects use OMGs modeling standards, including the Unified Modeling Language (UML), Business Process Model and Notation (BPMN) and Model Driven Architecture (MDA).

IIRA is presented as follows:

This Reference Architecture is a statement of what the most important Industrial Internet architecture components are, how they fit together and how they influence each other. It reflects consensus on major architecture questions among participants from energy, healthcare, manufacturing, transportation and public sectors.

I will look closer at IIRA in a future blog post.

IIC and Plattform Industrie 4.0 in March 2016 announced that they will work together to align RAMI 4.0 and IIRA – Cooperation Among Two Key Leaders in the Industrial Internet – see press release and blog. They released some initial mappings:



Industrial cultures and their “movements”

RAMI 4.0 and IIRA are the two major deliverables from the two “movements”, Industrie 4.0 and the Industrial Internet. Representatives from these “movements” were brought together in a panel here the other day at the Hannover Messe, and a report, BAM! POW! Industrie 4.0 Meets the Industrial Internet!, notes that

In the end, the panel did not agree on whether there would be ultimately one platform or many. But they did agree that they share a common view on the need to gain an understanding of how things should function and making sure that they interact.

Kris Bledowski from the US-based Manufacturers Alliance for Productivity and Innovation compared the movements about a year ago:

Comparison of Industrie 4.0 and the Industrial Internet Consortium. Source: MAPI Foundation

Bledowski sums it up:

  • Industrie 4.0 strives to optimize production while the IIC’s research targets returns to any asset
  • Industrie 4.0 works on standardization whereas the IIC works on enabling platforms that might set future standards
  • Industrie 4.0 is reactive to a fast pace of high-tech innovation; the IIC proactively pushes the frontier of any internet-enabled application

Generalizing the Reference Architectures

The Purdue Reference Model is a key element in PERA, the Purdue Enterprise Reference Architecture, the early 1990s reference model for enterprise architecture. PERA is an example of what was then called Reference Architectures of type II. Other such architectures were GRAI-GIM and CIMOSA.

Over the years, many other “industrial” reference architectures have been established. Many of these are sector-specific. For example, in the oil industry, POSC Caesar Association (PCA) and MIMOSA have established PCA-MIMOSA Reference Architecture Framework for Integrated Engineering and Operations in 2013. It describes

a reference architecture for defining, designing and classifying IT applications, systems and infrastructure in the upstream oil and gas industry, downstream petrochemical industry, and for engineering, procurement and construction projects.

GERAM framework components

In 1994 then came the Generalised Enterprise Reference Architecture and Methodology (GERAM), which also comprises a framework and methodology. GERAM became part of ISO 15704 “Requirements for Generalised Enterprise Reference Architectures and Methodologies” in 2000.

Fast forward, and many frameworks and methodologies later, GERAMs authors did a recent review of the last 20 years with reference architectures, and observed,

We believe that the future of EA is in its ability to develop an interdisciplinary language and theory enabling a concerted and synergistic application of contributions of underlying disciplines (results from management science, systems, industrial, manufacturing and software engineering, IS, Artificial Intelligence, and so on).

GERAM is a valuable baseline meta-framework  – to discuss the above, to create new theories, schools of thoughts, integration of engineering practices and tools, explanations of how technologies can be part of EA, methodologies for EA implementation, and Partial and Particular models for re-use.

As discussed in a previous blog post, and explored in a Special Issue on Future Perspectives On Next Generation Enterprise Information Systems of the Computers in Industry journal, we need to renew our reference architectures and architectural practices:

No doubt that the next generation of enterprise information systems will continue emphasising the need for scalable, reliable, extensible, flexible, highly available and maintainable systems architectures providing ubiquitous, plug-and-play, secure, interoperable and networked solutions to realise smarter and collaborative systems, platforms and ICT infrastructures for all entities operating in a common business ecosystem.

The reference architectures we define and use must reflect our architectural visions. RAMI 4.0 and IIRA are two different visions. Which one will be best? As we architects always say, “it depends”.

A Trip to Automation Valley

automationvalleyQualiWare and 17 other member companies of Manufacturing Academy of Denmark (MADE) went on an Industrie 4.0 study trip to Automation Valley in North Bavaria last week. The trip was arranged by MADE together with the local chamber of commerce and industry and the Royal Danish Consulate General in München.

The Digital Factory

Siemens, one of Germany’s largest companies and the largest engineering company in Europe, has taken its own medicine  – digitalization and Totally Integrated Automation (TIA) – and has built a digital factory in Amberg in Bavaria.

The facility is a prime example of advanced product automation and has received numerous awards. The Amberg factory already combines the real and virtual worlds: Products communicate with machines, and all production processes are optimally integrated and controlled via IT. Siemens

Siemens says:

The facility is a prime example of advanced product automation and has received numerous awards. The Amberg factory already combines the real and virtual worlds: Products communicate with machines, and all production processes are optimally integrated and controlled via IT.

The factory is essentially a fully operational demonstrator for many of Siemens’ own products and brands. Since the factory actually produces critically-important equipment for digital factories, one could call it a factory factory, and one may start wondering whether we visited the real-world Cyberdyne (as known from the Terminator movies).

amberg-humanSiemens told us that they were quite content having reached a 75% level of automation in Armberg, and that it currently is neither feasible nor desirable to automate further in this kind of production.

The continued human intervention will not disappear with the digital factory, but roles and competencies will change dramatically. Shop-floor work merges with administrative and analytical work, and desktops with computers now invade the shop-floor alongside the robots, sensors and augmentation systems. How the different roles and responsibilities change will depend on many things, not least organisational culture and politics. When sensors and big data analytics become the new supervisors, middle management must find new work, or become extinct, for example.

3D Printing

After huge Siemens we next visited FIT AG, an additive design and manufacturing (3D printing) company with (I think) 200 employees. They introduce ADM and themselves like this:

Additive Manufacturing (AM) is a disruptive manufacturing technology for complex parts in plastics and metal such as Aluminum, Titanium, tool steel, stainless steel, and Inconel. Different to traditional abrasive or forming technologies, additive manufacturing builds three-dimensional objects layer by layer. Leaving the known limitations of conventional production techniques far behind, these objects can be of almost any shape or geometry. Additive manufacturing is used efficiently for single parts as well as mass production. In order to exploit the full potential of additive manufacturing, its chances as well as specific challenges regarding design and technical issues must be well-known. With 20 years’ experience in this field, the FIT Group is an expert not only for AM, but the world-leading specialist for Additive Design and Manufacturing.

Here are some examples of their prints:



FIT uses leading-edge AM technologies and works closely with 3D printer vendors to become able to deliver ever more advanced products on ever more markets. FIT is growing fast, and we visited their new printing facility in Lupburg, which is already (partially) open for business, as Europe’s first commercial high volume additive manufacturing facility.

Additive Design and Manufacturing is an enabler of radical innovation, and FIT’s value proposition is basically that you can now produce and manufacture some designs that were previously if not impossible then impractical to produce. AM itself is today far from competitive to standardized mass-production, but is beginning to be interesting for mass-customization and complex product in higher volumes. But the real strength today is in rapid prototyping and design iterations for product innovations. For an example, see FIT’s case video about a race car cylinder.

Organizationally, ADM is to industrial designers/product engineers and production engineers/shop-floor what devops is to service designers/IT developers and IT service managers/IT operations. It is going to be interesting to see how this will work in an industrial setting, which has traditionally had very .

Green Factory

greenfacThe last visit was to the Institute for Factory Automation and Production Systems (FAPS) at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) which is a research leader in cleantech. FAPS is involved with Green Factory Bavaria:

The Green Factory in Bavaria combines the research expertise of all relevant fields within energy-efficient production disciplines, such as mechanical engineering, production engineering, electrical engineering, computer engineering, chemical engineering, materials science, and economics. These research fields consider all significant transformations of energy to movement, to lighting, to information processing. This even extends to for manufacturing processes as well as heating, cooling and air conditioning control, which are dedicated for the usage of energy in production, logistics and administration. With a clear focus on energy efficiency in production, the interdisciplinary collaboration of the Green Factory Bavaria is integrated into an internationally viable research network.

The FAPS team demonstrated a range of research results which, for example, use much less electricity than current solutions. Or less material. It should go without saying that such research is incredibly important at many levels – from “saving the planet” over “viable enterprise” to “profitable growth/competitive advantage”. A group of experts discussed the “digital green agenda” in Greening IT. As a registered user, you can download the book here.

Augmented Reality

augmensysOne of the days in Nürnberg was a networking day for Danish and German companies. Or DACH companies; one company I found particularly interesting is an Austrian company, Augmensys, that provides and develops Augmented Reality software for professional use in industrial environments.

Established in 2011, Augmensys is a pioneer for efficient data management without frictional losses throughout the process industry. Their UBIK platform is an innovative mobile data management software with Augmented Reality support, made solely for use in enterprise scenarios.

Augmensys is currently focusing on tablets, but also works with helmets and smart-gadgets of various kinds. The sometimes rather special settings for the relevant usage scenarios – for example underground without GPS, wifi, etc – is a key challenge. Also, the human-device interaction is a challenge, since it’s not always practical to use, say, a tablet.

In some industrial (and other) settings, augmentation technologies are embedded in the environment and interact with machines, robots, sensors and other “things” – and people. For example, a Danish meat-processing facility uses laser projection for guiding the meat-cutters.

Enabling Industry 4.0

So, the Germans call all of the above Industrie 4.0:

When components communicate with the production equipment by themselves, or order a repair to be undertaken when needed – when people, machines and industrial processes are intelligently networked, that is “Industrie 4.0”.

Industrie 4.0 is a central element in the German government’s Digital Agenda program. The German manufacturing industry is, as our study trip showed, already fully engaged in realizing Industry 4.0.

The digital agenda is a global agenda, and Germany’s Industrie 4.0 is of course also a strong national agenda for German competitiveness in the global markets. With “players” such as Siemens and SAP, Industry 4.0 could be Germany’s export good #1.

There is however also a risk at stake: Maybe Industry 4.0 works better outside Germany? Or whichever variants other countries call their digitalization efforts.

The Danish delegation returned home with a lot of inspiration – both from the Germans but also from each other – and will continue working together to enable the continued digitalization of the Danish manufacturing industry. Which will probably continue to use Siemens and SAP as major suppliers for their digital platform.
