Single source of truth – the time’s come for Industry 4.0!

However, throughout the entire production process, from the purchase of raw materials to the sale of products, countless data are generated that are somehow interrelated. It is therefore not without reason that a central demand in the context of digitisation is the Single Soruce of Truth. This concept of data storage enables all departments to access a central data source which is constantly maintained and therefore only contains consistent and redundancy-free data. This data storage prevents errors due to the use of different data bases, but above all it makes certain evaluations possible. Only in this way can the profit of a company be consistently depicted over the entire value-added chain and across all levels. It is not without reason that it is considered indispensable to lead Industry 4.0 projects to success.

.Whoever has had to grapple with the field of data and its evaluation is sure to have experienced some nerve fraying moments. Chafing at the bit with your head full of creative ideas, you’re bound to come up against a brick wall sooner or later. Some data are available, other information is there too – but for the next batch you first need to submit five applications to actually get anywhere and, in the worst case, you’ll be handed a collection of loose sheets… That initial contentment after having overcome the first hurdle will soon disappear once you’re confronted with the issue of data quality – a challenge that may well leave you tearing your hair out.

It certainly rings true as a rule of thumb: about 70 % to 80 % of the time spent on data analysis is devoted to data preparation. Of course, some of the steps are coordinated specially to the relevant analysis method. But a lot of things can be arranged in advance so the data can be used directly. Once merged reliably and cleaned, the data from all data sources should be free of redundancy and unique with a correct time stamp. Plus it needs to be up-to-date. Because this is the only way to implement insights form data analysis without a huge amount of extra work in realtime-based applications.

Single source of truth truly a milestone

I’m now concerned with the whole business when it comes to data derived directly – in the broadest sense – from the process. Innumerable data results across the entire production process from purchasing the raw materials through to selling the products, with various interrelations linking this data in one way or another. So it’s not without reason that a central claim of digitalisation is the single source of truth.

This concept of data retention enables all departments to access a central data source that is continually maintained to make sure it contains only consistent and redundancy-free data. Such a data repository prevents errors by using different data principles, but above all it’s vital in enabling certain evaluations. Only in this way can a company’s profit be mapped consistently over the entire value chain and across all levels. In fact, it can be regarded as indispensable for realising Industry 4.0 projects successfully.

How the whole thing works

Single Source of Truth

As an employee who loves data, you’re sure to say “At last!”. Rubbing your hands with glee on your way to the next department to ask for information. Only to discover: They’re stewing in their own juice there, an unwelcome surprise for you “Damn, nothing’s actually working!”.

In response to the question whether someone’s demonstrated how the whole thing works. You hear: “Yeah, someone came – he showed us some features by clicking around wildly. But we didn’t really understand everything.” Already somewhat disillusioned, you knock on the next department with your list. Only to be turned away briskly at the door. “What do you want from us? This hasn’t got anything to do with you. We’re already looking into the matter.”

Sweeping systematic transformation to Industry 4.0

This or other examples occur time and again within the context of digitalisation. Digital transformation actual entails (among other things) continuous further development and networking. Not only technically but also in terms of personal growth. Usually such a transformation is not so easy to master. And without a clear strategy or focussing on the company itself with all its individual circumstances, it’s sure to fail very quickly. That makes the change difficult especially for small and medium-sized companies who don’t have specialist staff. So-called maturity models provide support here. Based on questionnaires, companies can be classified in regard to the digitalisation’s status quo. In both technical as well as organisational and cultural terms, depending on the provider. What’s more, general recommendations for action or suggestions towards a customised roadmap can be derived form this.

After a quick look in the Internet you’ll soon discern a whole series of maturity models available with various focal points. On the one hand, it’s certainly great how you can carry out a complete series of tests immediately online. But choosing the right tests can be very difficult owing to the sheer number on offer. A topic the VDI Guideline Committee STEPS has been tackling. STEPS = Systematic transformation and evaluation of production systems. Because only in this way do projects like those described above stand a real chance.

Structured rating system

From quick check to individual roadmap – our team has closely scrutinised the maturity models, categorising them by various criteria. A structured rating system means the guideline will help you when choosing the model suitable for your needs. Have I piqued your curiosity? We’re currently adding the finishing touches to the guideline – then it’s hopefully ready for the greenprint. I’ll let you know when the time comes. Perhaps including a good suggestion for a maturity assessment.
