A few days ago a made the headlines about how absurd Bitcoin energy consumption has become. It is well summed up in this but let me give you one take-away: Bitcoin mining and transactions will soon consume as much electricity as Switzerland. According to (where assumptions and sources are well documented so that you can get your own opinion on how reliable it is), energy consumption has raised by 30% in the last month only and places the Bitcoin network a couple of steps behind Ireland. In other articles from less renown sources - and maybe less reliable so I spare you the links, but this information is easily googable - it is also mentioned that one Bitcoin transaction uses 5000 times more energy than a Visa transaction!

I was considering buying a fraction of Bitcoin just to see how it was done and what I could do with it, but now that I am aware of the environmental impact there is no way I will. I'm checking out other crypto currencies that have been substantially better eco-designed using different kind of algorithms. Digitization leaders need to be much more aware of sustainability Eco-design and sustainability unfortunately are absent from most shortlists of benefits or even requirements when you think of digitization. Most often you are looking for 'efficiencies' which is the current politically correct word to say you will have workers laid off - but even though social impacts of digitization are one of my prime concerns, there are not the topic here so I will not discuss them further. Automation, digitization, artificial intelligence all require energy to function and implementing such solutions will have an impact on your environmental footprint. As leader of my employer's incubator for Industry 4.0 solutions, I am often presented with devices and solutions that will help increasing our equipment or process efficiency.

All of them involve cloud-based solutions, so sustainability-aware customers should be careful in making sure that at least the infrastructure running the target system meets their own sustainability requirements.

Some services also require additional devices such as tablets which are short-lived and not repairable, which should be a concern when you operate them in an industrial environment. I am very worried about the current trend we see with hi-tech consumer goods being less and less repairable - yes Apple I'm especially thinking about you and your 10 years stretch of not allowing your customers to replace batteries in Iphones and Ipads, but unfortunately you are not the only one out there in that trend. Ibps Rrb Office Assistant Previous Year Question Paper Pdf In Hindi. For Industrial applications, we may be tempted by going also for the cheap devices and just dump them and replace them when they start failing, but this goes against all sustainability principles that a vast majority of companies are saying sit as their core values. We are all accountable for sustainability and we are all actors in building it. Which brings me to the last point I wanted to make, about how Lean fits in all this.

Digitization works better on what has already been optimized The most visible aspect of Lean management is waste elimination or reduction. This is sustainability by and large.

Every action, every operation has an environmental footprint which can be positive or negative. In Lean (as long as we see a positive footprint action as value added), eliminating waste or reducing waste should result in increased sustainability and value. And what about digitization? I have often seen digitization started before process streamlining or waste elimination and reduction was even considered. Companies are mistaken if they think they will accelerate in 'skipping this step'. It's not skipping a step to move forward quicker, it's loosing an opportunity to improve even more.

Okay, you may have your digital solution sooner if you do it that way. The problem is, there are high chances you automatized or virtualized waste by doing so. And this is definitely something you don't want. Once your waste is automatized or virtualized, it is much harder to identify.

And once it is identified, it is also much harder to eliminate because the root causes and impacts may not be tangible things anymore. Of course, analytics tools will help you there, but that means you need a new tool to correct the almost new tool you may not even have needed in the first place. Doesn't sound such a good idea to me.

Waste reduction should first be considered when things are physical and tangible before going for digitization, this is in my humble opinion how we can leverage most digital opportunities to their optimum. And yes, companies may be in need of new tools to spot and eliminate wastes in Operations in the first place. This is where my thoughts trailed after reading these Bitcoin energy consumption articles. In a nutshell: • It's not because you digitize that you're more sustainable • Lean can (and should) be done with sustainability in mind • Lean is among the first things to consider in a digital journey That's how I personally connect the 3 concepts.
