Introduction to Method Engineering - Reasoning levels

4 important questions on Introduction to Method Engineering - Reasoning levels

How many reasoning levels (IRDS modeling sequence) for models are there and what are they?

There are four levels, namely:
  • M3: Meta-meta-model level;
  • M2: Meta-model level;
  • M1: Model level;
  • M0: Data level.

Which reasoning level describes the concept Method Engineering?

The Meta-model level (M2) describes the concept of Method Engineering.

Which level of reasoning is abstracter in its statements and what does it describe?

M3 is the most abstract in its statements.
It describes the following subjects: concept - association - object.

Can this reasoning level or sequence be used infinitely (oneindig)?

Yes, sequence could be continued infinitely, but four models are enough for most modeling purposes.

The question on the page originate from the summary of the following study material:

  • A unique study and practice tool
  • Never study anything twice again
  • Get the grades you hope for
  • 100% sure, 100% understanding
