POS systems, product data, payment, scales, age verification, security functions, monitoring and other applications all need to communicate reliably with one another (see also <a href=\"https:\/\/www.dieboldnixdorf.com\/en-us\/retail\/insights\/whitepaper-retail\/checkout-of-the-future-report\/\">Diebold Nixdorf: Checkout of the Future<\/a>).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Only when these systems work together properly can a reliable data foundation be created.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The logical chain is:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Connectivity \u2192 Data \u2192 Analysis \u2192 Management.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The objective is not to collect as much data as possible. What matters is making the information available that is actually relevant to day-to-day operation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>What is the usage rate?<\/li>\n\n\n\n<li>How long do customers wait?<\/li>\n\n\n\n<li>How often do employees need to intervene?<\/li>\n\n\n\n<li>At which points are transactions abandoned?<\/li>\n\n\n\n<li>Which error messages occur particularly frequently?<\/li>\n\n\n\n<li>Which products or process steps regularly cause problems?<\/li>\n\n\n\n<li>How does throughput change over the course of the day?<\/li>\n\n\n\n<li>Where do unusual patterns or anomalies occur?<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Only when this information is available promptly and meaningfully connected can operational decisions be derived from it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A dashboard alone does not create transparency. What matters is whether the values displayed help identify specific causes and improve processes.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Level 4: Usage in self-service | Usability &amp; customer experience<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">But even the best data architecture does not explain why a particular value occurs.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A high intervention rate initially tells us only <strong>that<\/strong> employees frequently need to step in.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It does not yet explain <strong>why<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Perhaps an instruction on the screen is unclear.

But only observing and analysing the actual user journey can reveal whether the cause is, for example, unclear operating logic, a poorly understood message or an unfavourable process step.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The same applies to waiting times, interventions, operating errors or low usage.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Metrics provide indications (see <a href=\"https:\/\/dr-rainer-eckert.de\/en\/self-service-metrics-process-improvement\/\">Retail Engineering: Self-Service Needs to Be Understood<\/a>).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Actual usage provides context.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Only together do they create the basis for targeted improvements.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Measuring is not enough.
