Paperless manufacturing: What's the status-quo?

The goal of paperless manufacturing is actually already in the name: It's about manufacturing without printouts or paper-based documents. But if we look one level deeper, there is much more to it. After all, replacing a sheet of paper - let's say - with a PDF file is not the answer. Sure, the paper is gone, but instead there are now countless files lying around that are just as prone to errors, become outdated and make it difficult to reuse data.

So let's add: paperless manufacturing means eliminating paper from production in favor of end-to-end digital processes and systems. “Consistently digital” is the key here, because only then can the data that was previously stored on paper be used directly and in real time for documentation, further processing or other services. This also includes direct digital interaction and feedback options for your employees in production.

Saving time through paperless manufacturing

Paperless manufacturing helps you to save time at various levels. If all the necessary information is available digitally at the workplace, you can significantly shorten information paths and save your employees the hassle of searching for the right documents. Information is always available immediately and continuously. This increases the efficiency of your workers and speeds up throughput times.

Error-free, paperless work

Once you have established end-to-end paperless manufacturing, you eliminate all media disruptions - and therefore also the places where errors are most likely to occur. Up-to-date digital work instructions also lead to a lower error rate and less rework and rejects. And because all processes, data and inputs are available digitally, quality control is also noticeably easier.

Long-term effects of paperless manufacturing

Paperless manufacturing paves the way for your workers to work flawlessly and efficiently in an end-to-end digital environment. Sooner or later, this will be reflected in higher customer satisfaction and ensure your competitiveness.

Well, that all sounds great, doesn't it. Then just throw away all the paper and off you go. If it were that easy. As always, you need to create the conditions for paperless manufacturing (if you haven't already done so in some form). Let's take a look at this from both a technical and an organizational perspective. Let's start with the technology.

Introduction of various software solutions for paperless manufacturing

The right software is the be-all and end-all. Unfortunately, it is almost impossible to recommend or even name the one system that will solve your paper worries. As is so often the case, it depends on your needs. Possible software solutions could be:

• a document management system (DMS): as a supplier of digital documents, this is a good starting point for initial, quick successes
• a leading system for central data management, e.g. ERP or MES: here you can create and provide production orders and release orders, parts lists, drawings, work instructions and routing cards.
• Software for production planning and control, e.g. APS: enables detailed planning of resources, materials and tools as well as rapid response to spontaneous changes in production
• CAD, PDM or PLM systems: take over the digital representation of drawings, etc.
• applications for digital employee communication: can be used in a variety of ways throughout the company, e.g. also for sick notes, instructions, protocols
• worker guidance system: digital system for providing production-relevant information to the worker and for recording production-related data and information

Introduction of hardware

The selected software often requires adequate hardware support and not every workstation is already equipped for digitalization. A worker guidance system, for example, also needs a screen to display digital work instructions to employees. Other hardware investments can also be useful on the way to paperless manufacturing:

• digital material removal, e.g. in the form of a pick-by-light system
• (mobile) end devices for providing data and for collecting feedback or operating data (tablets, scanners, etc.)
• tracking solutions, e.g. barcodes or RFID technologies
• IoT sensors or devices, e.g. for monitoring temperature or pressure directly on the machine

The infrastructure for paperless manufacturing

Without going into too much detail: Does the WLAN reach to the last corner of the factory floor? And if not, is that a problem for the use of your future digital system? The right IT infrastructure is also an essential prerequisite for successful paperless manufacturing. This includes Internet availability as well as IT security.

Step 1: Evaluate the benefits and risks of paperless manufacturing internally

As with all innovation processes, the path to paperless manufacturing does not begin with the search for a solution. The first step is always the internal view: What does the step towards paperless manufacturing mean for your company? Clarify this:

• which processes are affected and which use cases exist
• what impact the changes will have on your employees and the company as a whole
• and what specific goal you are pursuing.

It is best to get the employees concerned on board right from the start in order to avoid hurdles later on.

Step 2: Create a schedule

Paperless manufacturing has so many advantages, so it's best to get started tomorrow. Or not? No, because a time and action plan is important. Define the steps and measures as well as the resources required. Focus on individual, promising processes that you can start with.

But: always keep in mind that you are ultimately establishing a holistic, cross-company solution. cross-company solution. Isolated solutions are taboo.

Step 3: Prioritize the processes

As already mentioned, the first step should be to identify the processes that promise success. To do this, take a look at all the processes in question and determine which ones will benefit the most. Evaluate your processes according to standardized criteria such as simplicity of implementation, necessity of process digitalization, benefits for the company, etc. This will help you find the processes with the highest priority, which you should tackle first.

Step 4: Pilot project for paperless manufacturing

With your first project, you have the freedom to test and experiment. What solutions are available on the market? How well do the solutions work in your company? How can you achieve the goals you have set?

The aim of the pilot project is to find the ideal solution for this first and possible further steps and to sharpen the requirements. At the end of the pilot project, you should arrive at a flexible, digital solution that fits your needs and is open to other scenarios.

Step 5: Roll-out to the entire company

Once you have found the right solution and fulfilled all the technical requirements, nothing stands in the way of a roll-out. But the work is not yet done. Now you have to:

• clearly define and document the new processes - digitally, of course
• train your employees on the how, what and why of the new solution
• schedule regular maintenance of software and devices
• monitor your processes in terms of CIP.

When it comes to paperless manufacturing in production, a worker guidance system is a valid solution. Paper documents or inefficient file formats such as Excel or PDF are often still used, especially where manual work is carried out. And this is precisely where a worker guidance system can come in and create digital consistency and efficiency. Let's take a look at our weasl system and see the concrete benefits:
