+|Quality Demand |Solution approach
+|Functional Suitability a|
+* *Exchange* Ensure that the exchange of system data between the system component works flowlessly.
+* *Requirements* Ensure that all functional requirements as descripted in the contrect are fulfilled.
+|Performance efficient a|
+*Not important*
+|Compatability a|
+*Not important*
+|Usability a|
+* *Language* Ensure that every word on the web interface corresponds to its definition in the industry.
+* *Learnability* Ensure that the system can be easily used and understood by its users. This can be realized by e.g. unambiguously describing the content of inputs with labels or tooltips.
+* *User error protection / Error handling* Protect user against making errors. Invalid inputs must not lead to invalid system states.
+* *User interface aesthetics* Provide a pleasing and satisfying interaction for the user.
+* *Accessibility* Ensure that people with a wide range of characteristics can fully use the system. This can be realized by e.g. using suitable font sizes and color contrasts.
+|Reliability a|
+* *Tests* Add tests to ensure functional integrity.
+|Security a|
+* *Confidentiality* Ensure that only data can be only accessed by people who are authorized to access them. This can be realized with _Spring Security_ and _Thymeleaf_ (`sec:authorize` - tag).
+* *Integrity* Prevent unauthorized modification of data. This can be realized with _Spring Security_ (`@PreAuthorize` - annotation).
+* *Accountability* Traceability of actions or event to a unambiguously entity or person. For this application, every `Order` should be linked to a `Customer`.
+|Maintainability a|
+* *Modularity* Compose the application out of discrete components such that changes of a component have less impact on other components.
+* *Reusability* Ensure that components of the system can be reused by other components or systems.
+|Portability a|
+*Not important*
