The ultimate goal of any training is to help the learners achieve their desired learning outcomes and improve their performance. Therefore, you should always keep the learners in mind when using an instructional design model. You should involve them in the needs analysis, design, development, and evaluation stages of your training project. You should also consider their characteristics, preferences, motivations, and challenges when creating your training content and activities. For example, if your learners have different levels of prior knowledge, skills, or experience, you might want to use a model that allows for differentiation, personalization, or scaffolding, such as the 4C/ID or UDL models.
