Flows for the detailed search in the Siewert & Kau webshop lacked efficiency. It was hard-to-find and complicated. The shop is specialised in electronic components, products easy to be mixed up and named with numbers or abbreviations only. I optimised the usability of the search functions and result lists. The search for professionals must include various technical parameters as filters. Highly compacted results lists show many hits in one view. A second result view including product images still shows a maximum of the technical details.
