Also Known As: First Things First, Focus Beyond the Solution
After an initial introduction to patterns, the students will be required to apply them as well. The application requires the choice for a pattern and the application of its solution. You now want to show students how to start applying patterns in a correct way.
Students who start to learn patterns often go straight to the solution and apply it, hastily skipping the problem, context, forces, and consequences parts of the pattern.
Therefore: Focus first on the problem, context, and forces parts of a pattern. Make sure the students understand the need for a good solution. Then introduce the solution and the consequences of applying the pattern.
We consider this pattern a true invariant, as independent of the domain a specific pattern should only be applied after all relevant information has been gathered and analysed.
