For our upcoming report on Asset Integrity Management, we interviewed several leading participants in the space. During our discussions, one leading trend that came up in nearly all conversations is digitalization. The term digitalization, seems self-explanatory, right? Well, I thought so too. However, confusion cropped up when I was reviewing all my interview notes. Some of my interview notes said digitalization while others used the term digitization. This made me wonder, if the interviewees meant the same thing when they mentioned the terms digitalization and digitization.

Good thing is, in today’s world, one does not need to find a dictionary or rush to a library to resolve such confusions. I googled the term digitalization and opened up my most trusted resource of definitions and meanings, Merriam-Webster site. Here is the definition, I found there:

 

 

not what you expected, right? So, I checked another trusted resource, Oxford Dictionaries. Here is the definition:

 

So, I learned that digitalis is a genus of about 20 plant species, which has medicinal qualities and helpful to control heart rate. Administration of digitalis to a patient is referred as digitalization. This certainly was not the definition, I was expecting.

May be digitize is the correct term, I thought. Here is the official definition, I found:

 

While this definition is somewhat closer to my expectation, the scope of this definition also seems limited.

To me, digitization and digitalization means the implementation of advanced technologies such as big data, industrial internet of things, and analytics, to bring improvements to existing processes and business models. Various other industry participants also seem to have a similar definition and use the two terms digitization and digitalization interchangeably. Even at ARC, we have not standardized on any one term and use both in the same context.

So, which one is correct?

I believe, both are correct. Language is evolving slowly over time. However, in the last decade, we have observed some rapid changes in language due to various factors including globalization, rapidly developing technologies, and social media. For example, in this blog itself I have used a relatively new verb, “google”. Google is such a popular search engine, that the word google has now become a universally accepted verb for internet search. In-fact, it was officially entered to the Oxford dictionary in 2006.

Along with new technology, new words are also being invented. Smart phones with front facing cameras have made it so easy for users to take pictures of themselves that we now have an official word for it, selfie. We are also giving new meanings to various existing words. One such word is cloud. Earlier cloud used to mean “a visible mass of condensed watery vapour floating in the atmosphere, typically high above the general level of the ground”. Now the word has a new meaning as well, “a network of remote servers hosted on the Internet and used to store, manage, and process data in place of local servers or personal computers”. Various other words such as, friend, tag, follow, windows, platform, tablet, (and the list is endless) have also got new meaning these days.

With rapidly changing technology, the two words, digitization and digitalization, have also got a new meaning. Although popular in the industry now, these new meanings are not officially in the dictionary yet. However, with the growing trend of digitization/digitalization, both or at-least one will officially acquire the new definition soon. Till then, I guess both are correct.

What do you think? Do you prefer, digitization or digitalization?

The terms Predictive Maintenance and IoT have been intertwined and used significantly over the last several years has caused the true meaning of prediction in this context to be difficult to ascertain.  These variations or differences in what a Predictive Maintenance program is and how it is actually construed has caused Manufacturers and distributors to believe they are conducting a predictive maintenance program for their operations or field services when in fact they are actually providing a more exact condition-based preventative maintenance program and clouding the reasons why they originally pursued this endeavor.

 

Understanding why this is such a widely pursued initiative provides critical context for understanding a predictive maintenance program.  Maintenance is purely a cost, and while the costs of maintenance are generally preferable to the costs associated with a break-fix program, maintaining assets is simply a cost and as such, it’s a cost that has to be minimized.  Predicting asset maintenance needs has shown to be 20% - 30% more cost effective than a preventative maintenance program.  It’s also a cost and problem that companies have shown they are willing to pay for someone else to manage the maintenance headache of equipment for them.  And once revenue becomes a focal point, so does competition.

 

This reveals the second and more important reason for understanding the nuances of a predictive maintenance program; competitive differentiation and profitability.  Understanding the different levels of outcomes with the various stages of predictive maintenance provides better clarity.

Usage Rate, Condition, Prediction

 

The first level is understanding usage, with the help of IoT sensors, of a machine with simple alerts that are triggered when thresholds are passed.  These thresholds can represent the length of time, units produced or other usage based metrics.  When an alert is triggered maintenance is completed.  This type of program is akin to automating the manual data collection efforts of a preventative maintenance program.  It will decrease the costs of collecting data from a piece of equipment and enable a more effective preventative maintenance program but it will not have a drastic impact on overall maintenance costs and will not support a differentiated maintenance services program.

 

The second level is understanding the operating conditions of the equipment in general and directing maintenance actions based on the differing levels of condition understanding.  At the basic level, this can involve simple, single variate analysis such as temperature monitoring when a piece of equipment is in use.  At a more sophisticated level, this involves complex multivariate analysis to determine condition such as the temperature, revolutions per minute and vibration of a piece of equipment over an extended length of time.  This is a more complex and complete understanding of machine condition.  This becomes more valuable when the actual conditions are compared to an expected degradation pattern.  Most importantly, this level of understanding provides the beginnings to a differentiated service program because it provides the ability to begin understanding time until failure, albeit the time horizon is days to weeks as opposed to weeks to months of a true predictive program.  It also allows field service programs to provide powerful reasons to bundle products and services in a single contract.

The third and final level is utilizing aggregated continuous operating condition to drive a predictive model.  This yields continuous understanding of condition equipment, identifies equipment degradation pattern changes and predicts remaining useful life of individual components.  This level is actually predictive maintenance as it is termed and, contrary to many beliefs, cannot be reached without a data scientist and a method for deploying and executing predictive models.  To be able to actually predict remaining useful life and machine failures weeks to months prior to their occurrences and with a 95% or greater confidence level, the expertise of the data scientist, the ability to support algorithms with high run time complexity and having good historical data on machine performance with failures is critical.  Involving maintenance staff or field technicians provides some value in contextualizing failures but they are typically not the strongest resources needed to complete this task.  Additional technologies such as artificial intelligence and machine learning are also valuable in supporting the long term viability of a Predictive Maintenance program and should be incorporated as soon as possible.

 

Obtaining this milestone enables companies to create differentiated service contracts because maintenance is only performed when needed resulting in the lowest cost to repair, service parts and components can be ordered on demand, freeing up net working capital and services can be automatically scheduled well in advance.  Most importantly, once an organization is comfortable relying on this type of a program, the enterprise can create outcome and usage based contracts.  This enables long term subscription contracts for assets which carry higher profit margins while providing customers with a program that matches their exact equipment requirements as the outcomes are based on what they need and what they are willing to pay for.

 

While the meaning of predictive maintenance has been stretched to encompass all of the different levels of capabilities discussed, to truly be able to predict remaining useful life and perform maintenance/service actions based on them an enterprise needs the ability to obtain the data (IoT), understand condition, leverage condition data for prediction and automate tailored actions to support the end objective of providing a predictive maintenance solution at the lowest possible cost.
