Final answer:
"As-Is" process models map the current operational state without changes, essential for analyzing existing workflows prior to implementing improvements.
Step-by-step explanation:
The process models that represent the current state of the operation without any improvements or changes to existing processes are known as As-Is process models. These models are critical for organizations to understand how their processes currently function before any changes or optimizations are considered.
In contrast, 'To-Be' process models depict the future state of a process after improvements have been made, while 'Drill-Down' models provide a detailed breakdown of a process. The term 'AI' is not directly related to types of process models, but rather refers to Artificial Intelligence, which could potentially be integrated to enhance various business processes.
