Question: I have a hard time understanding #3 and #8 of [Lehman's Laws of Software Evolution](http://en.wikipedia.org/wiki/Lehman%27s_laws_of_software_evolution). 

The laws are:

3. (1974) "Self Regulation" — E-type system evolution processes are self-regulating with the distribution of product and process measures close to normal

and 

8. (1996) "Feedback System" (first stated 1974, formalised as law 1996) — E-type evolution processes constitute multi-level, multi-loop, multi-agent feedback systems and must be treated as such to achieve significant improvement over any reasonable base

The rest of the laws are clear to me. 

Could someone explain these two laws?

Answer: 
Law: 

3. (1974) "Self Regulation" — E-type system evolution processes are self-regulating with the distribution of product and process measures close to normal

**In other words 'an E-type systems growth inevitably slows as it grows older'.**

Not sure about law 3 yet, but here's my take on law 8:

Law 8 would be a perfect example of a successful agile project. The system is adapted to the changing requirements of users, product owners and other stakeholders. By using the system, users find out what they really want to do with the system. Product owners and management prioritize new features according to a changing environment and the team discovers better ways of doing things by gaining domain knowledge and experience. That sounds a lot like a multi-level, multi-loop, multi-agent feedback system.
