Scalability, Modularity and potential product enhancements are addtional views that have to be considered during the design phase. Therefore, it is mandatory to retrieve as much information as possible from the dedicated departments of our customers. An interview of customer's people, either in person or by phone, is essential to understand the critical points and the desired behaviour of the product. Standard parameters like materials of wetted parts, media compatibility and what the visual elements of the product should look like have to be known before starting the development phase.
