The OSI model is useful in network design and assessment because it makes network communications more manageable by dividing the processes up into smaller parts. The processes are broken up into 7 layers and each layer serves the one above it.
It allows categorisation of network components in both functionality and complexity.
It allows vendors to design products following the model, so different devices from different manufacturers will work together.
prevents collisions on a local network.

From a network design standpoint: Core Distribution Access
The network model, while useful for representing complex relationships, has several limitations. It can be difficult to design and manage due to its complexity, especially in large systems. Additionally, the rigid structure may not accommodate changes or new relationships easily, making it less adaptable than other models like the object-oriented model. Furthermore, its reliance on predefined paths can lead to inefficiencies in data retrieval and processing.
The risk assessment model provides a process structure to guide you in assessing risk.

Tyler's model of curriculum design is linear and prescriptive, with four key components: objectives, content, learning experiences, and assessment. Tabas' model focuses on students' experiences and emphasizes the importance of considering context, values, and reflection in curriculum design. Both models are used to guide the development of effective educational programs.
