Single process in a fictitious hotel using data flow diagram notation." The intention is to reduce one of the risks associated with short-term memory, namely, forgetting what is not immediately visible (‘out of sight, out of mind’). Ideally, all of the steps would be visible all at once (often a page or less). The basic flow within a process or use case can usually be described in a relatively small number of steps, often fewer than twenty or thirty, possibly using something like ‘structured English’. Each planned response may be modelled using DFD notation or as a single use case using use case diagram notation. The level of detail of each response is at the level of ‘primary use cases’. This approach helps the analyst to decompose the system into ‘mentally bite-sized’ mini-systems using events that require a planned response. Single use case in a fictitious hotel using use case diagram notation. Single process in a fictitious hotel using data flow diagram notation. "Event partitioning is an easy-to-apply systems analysis technique that helps the analyst organize requirements for large systems into a collection of smaller, simpler, minimally-connected, easier-to-understand ‘mini systems’ / use cases.
