With complicated issues, the best solution is not always immediately obvious. Typically, there are several possible solutions and different solutions that must first be recognized and then weighed against each other. The best solution in complicated issues is usually not obvious, but in principle knowable. Gaps in knowledge can easily be closed by supplementing the immediately available knowledge. Decisions can therefore be made on the basis of complete information. Examples of complicated issues are construction tasks. Best practices cannot be used directly to solve tasks involving complicated issues; instead, methodological knowledge such as logic, systematics, scoring, etc. is required to find solutions. Typically, experts are used in order to solve tasks involving complicated issues.
The next level is complex issues.
