4-2. Well-structured problems are easy to identify, required information is available, and methods to solve them are somewhat obvious. While often difficult to solve, well-structured problems have verifiable solutions. Problems of mathematics and time and space relationships, as in the case with detailed logistics planning and engineering projects, illustrate well-structured problems. For well-structured problems, leaders may use the problem solving process, troop leading procedures, or the military decisionmaking process (MDMP).
