What do reverse engineering and traditional forward design have in common?

Both forward engineering and reverse engineering are "engineering" at first, so the fields, disciplines and methods involved are basically the same, but the ideas are different. One is based on problem analysis and solution realization, and the other is based on solution analysis and resource realization.

Whether forward or backward, it is necessary to clarify the organization, implementation form and basic technology of the project.

The above is my understanding for your reference.
