In general, an evaluation is a reflection, is one still in the concept or how has the path changed. The evaluation should be a constant mindset during a process.

Evaluations can take place at different points in the design process. Depending on this, the focus is on different values. It is important to be clearly aware in advance what you want to check, otherwise it is a token exercise and the acquired information is of no use for the continuation of the process. " Before" is about ideas, intuition and hypotheses. These can be verified with Fiel Research, Interviews, Desk Research (Sources, Data, Related work, Precedents) discussions between experts and consultants and by means of Co-design and Participatory Design (an approach to design with all stakeholders). " During" refers to work-in-progress, directions. A review to see if the direction still matches or to become aware of what has changed and what the new role of the project is. This is found out by prototyping, documenting (reflection practice), going back to the field, enacting, storytelling and also in the format of discussions. "After" is the view on reaching objectives, missing objectives, contributions. This can be checked with study analysis, stats, typology of uses, quotes, report publication, exhibitions, dissemination. From the gathered knowledge, methods, lessons learned, guidelines (toolkit), taxonomy of related work can crystallize or emerge.

There are several methods, each with its pros and cons.

heuristic evaluation

****Is a usability inspection method for computer software that helps to identify usability problems in the design of the user interface. In particular, it involves evaluators examining the interface and judging whether it conforms to accepted usability principles (the "heuristics"). is a fast, cost effective method in contrast to usability tests.
