The web site is about the architecture of large and complex activity systems.

It abstracts from the experience of hundreds of architects.

This site is paid for through fees for architect training courses and for Avancier Methods.

The web site was initially a place to post answers to FAQS, then grew into a kind of a structured blog.

I added some training course materials so as reduce the size and cost of paper course manuals

I added papers and books I do not have the time or ambition to complete and find a publisher for.

The "Human Factors" material is more for entertainment, and not fully public.

Maintaining the site takes a great deal of time and effort, which has to be paid for in some way.

Individuals are entitled to read the documents in situ, and there is a lot that can be learned that way.

People wanting to do more than make individual use of the site should pay one way or another.

Normally, that payment takes the form of buying a course place.

A few organisations pay an annual licence fee for organisational use of the web site.

We don't give away everything for free.

We hold back some juicy stuff for customers who pay for our services.
