"The decisive factor is involving the staff members in creating change."

 

At KSB, Tanja Seibert heads the production of valves at the Pegnitz site – a business unit that is currently experiencing many changes due to the energy transition. How to communicate and lead change? In an interview with Stream of Stories she sheds some light on this question.

KSB.com: Ms Seibert, you are currently leading the valve production in Pegnitz through many changes. Are you a person who embraces change?

Tanja Seibert: To be honest, I am not exactly a pioneer when it comes to change. But standstill is not my thing either. Any changes I make are based on calculated decisions. When structural changes to buildings are required – meaning something has to be knocked down, generating a lot of waste – I initially don't like it at all. But then once the site has been somewhat cleared up and something great, something new is taking shape, I start feeling excited.

What is the reason behind the changes to the valves production in Pegnitz?

In Pegnitz we manufacture standard valves and customised designs for the industry and energy sectors. This is where the energy transition can certainly be felt. After the nuclear accident in Fukushima in 2011, business in the nuclear power sector receded in Germany. Orders from fossil-fuelled power stations also started to decrease. We quickly recognised that we had to re-position ourselves. We wanted to make our production future-proof: more efficient, flexible and sustainable. We asked ourselves what machinery we still need in the future. What valves are we going to produce in what product mix? And what market segments are we going to cover?

Valve production in Pegnitz

The Pegnitz-based valve production manufactures valves for applications with extremely high pressures and operating temperatures, such as can be found in power stations or industrial and chemical plants, for example. These valves withstand extreme conditions with pressures of up to 600 bar and temperatures of up to 650 °C. For this reason, individual components may have a wall thickness of up to 18 centimetres and weigh up to ten tonnes. Despite the high degree of automation and numerous machines, including welding robots, the production process still requires a large amount of manual work. KSB also manufactures specially customised valves in small quantities. As the valves are often used in critical areas they are subjected to comprehensive quality inspections and tests prior to leaving the factory. Having highly qualified and experienced employees is a decisive advantage for us in global competition.

What is going to change for your staff in production?

My colleagues working in production are mainly affected by the structural modifications of our buildings. For instance, we are going to combine two production halls into one. Naturally, working in a new environment next to different colleagues and in different workspaces will take some getting used to. We are in the transition phase right now. This week, for example, the first lathe was placed onto a low loader and moved to the other factory. Such a shift is always a bit chaotic. That's unavoidable. But we can also see that there is progress. Production has resumed at the shifted machines and work stations. It is working!

How have you involved your staff?

Initially, both the staff and the leadership team were quite concerned. Through meetings and workshops we managed to find a way together that we consider to be the right one, the one leading to success. During this phase we received comprehensive consultation from Global Operations, a KSB department that supports sites in improving processes. For example, we conducted individual workshops for every work station. Here, employees were able to create wooden models of their new work stations at a 1:1 scale. We then generated three-dimensional images of the production halls using the VisTable program where, fitted with 3D glasses, our employees were able to further develop their work stations. Where is what tool located? What hand movements do employees have to make? Where do they need some more storage space, where is the material delivered, where are screws and bolts, small parts and accessories kept? Our employees came up with some great ideas in this process. They suggested height-adjustable work stations, for example. Keeping in mind that they assemble valves that can be either small or very large, an adjustable workbench is simply better from an ergonomic point of view.

These changes have not only provided you with the opportunity to make production more efficient but also to make it more sustainable.

Even the fact that we will all be in a more compact space, in a single hall, increases sustainability. This will lower heating costs and energy consumption. It will save power. We used to store raw castings in the temperature-controlled production hall. To increase energy efficiency we decided that these components may just as well be stored in a hall without heating. This won't affect the bodies in any way but it saves us energy. Another contribution to sustainability is made by the photovoltaic systems the new hall will be fitted with.

Now that the changes are almost complete – what are your long-term objectives for valve production?

Naturally, the objective is to be future-proof or, in other words, to lower the structural costs in the factory while remaining flexible regarding the product mix. To continue to be able to respond to changed market situations. And this is hugely important: Since the middle of last year we have had a wave of high capacity utilisation for valves from the energy sector. This is not something we were able to predict and plan for two years ago. However, we are able to respond accordingly. We have got enough machine capacity and are currently in the process of slightly increasing our staffing levels again. We also need to maintain and further develop our expertise in welding technology, special materials and customer-specific qualification and documentation requirements. This will provide us with opportunities in new, demanding applications such as in energy storage or high-temperature electrolysis, for example.

What advice would you give to managers who have to create changes?

It is very important to involve your staff right from the start, to explain the concept and, where possible, have your staff create the change with you. So many ideas came from workshops with active staff participation. I was thrilled. I was fascinated. We have inspired each other in our team and developed some fantastic ideas. When one person thought "That will never work", another suggested a possible solution. Most of our staff are very proud of KSB and are happy to help shape change when they are given the opportunity. At the end of the day, they are the ones producing the products we sell – that’s something we must not forget.
