We strive to categorize our cards with the relevant labels, so that we can perform analytics on them. Cards should always include at least 1 colored label (e.g. Products & Services / Back-office) and often 1 or more grey labels (e.g., Motorbike, Car). The labels indicate the nature of the work to be done (integration, refacto, front-end) as well as the broad applications domain where this work happens.
