11 -First, we would have to determine the high-level goals for the study and the motivation behind them, since they can influence how we approach it. Then, we choose the evaluation approach, the methods that will be used, whether these are based on quantitative or qualitative data, and the process of data collecting, analysis, and presentation. At the same time, any practical issues, such as participants, budget, or schedule, are identified and a pilot study is performed if needed. It is important to adhere to any ethical procedures that are in place, to ensure the participant knows their rights and is protected. Finally, the evaluation of the data takes place, where it is determined whether the results are reliable, valid, without bias, unrelated to the environment and can generalize well.
