In practice integrated problem solving means that:

• Understanding the problem and solving the problem happen at the same time, not sequentially.
• Preliminary information is released early; information flow is not delayed until complete information is available.
• Information is transmitted frequently in small batches, not all at once in a large batch.
• Information flows in two directions not just one.
• The preferred media for transmitting information is face-to-face communication as opposed to documents.
