Level 1 of the C4 model is the Context diagram.

At this stage, your software is depicted as a box in the center of the diagram that has interactions with some specific users and/or other systems. Technical details are hidden away so that a clear message of what the system does and how it interacts with the “outside world” can be sent to non-technical people.

Although it is the simplest of all diagrams, it is the most crucial one at the same time. Often, people making decisions on whether to proceed with a given project or not and how much money/how many resources to allocate to it are top-level executives/managers who need not know the intricacies of technical implementation. All they need is a clear understanding of the system and its benefits or risks.
