Associated Websites

There are several websites associated with this one. These are for different aspects of the work we do. The separate websites provide specific focus for the topic represented.

Probably the oldest and largest research project in requirements engineering was the ISDOS project at the University of Michigan. Its most widely used and known product was PSL/PSA.

The intellectual origin of almost all systems analysis techniques, relational theory, and object-oriented thinking is the philosopher Rudolf Carnap. Many analytical approaches can be seen as derived from Carnap's constructor principles, resulting in discussion about models, metamodels, and metametamodels. There is discussion about this at the website devoted to metametamodelling (and languages). This topic is key for requirements engineering whether the target system to be developed is computer-based, or much wider (and could be a system that involves no computers).

Other websites are for books: (1) Business Process Analysis: including Architecture, Engineering, Management, and Maturity, (2) Emotional Abuse in the Classroom: the forgotten dimension of safeguarding, child protection, and safer recruitment, and, (3) Nuclear Weapons and International Law. Each book has its own website.

The book Nuclear Weapons and International Law has been published under the new imprint Peace Analytics which will soon have its own website.

The PSL/PSA Project

The PSL/PSA Project has made early, tentative beginnings in 2011. The goal is to make PSL/PSA available again, late 2016 or early 2017 in a reduced form called PSL-lite. A fiull PSL/PSA will be made available later, but careful consideration needs to be given to standard reporting to be supplied with it, as some of the reports with the original product are not useful.

PSL/PSA was originally available to the sponsors of the ISDOS (Information System Design and Optimization System) at the University of Michigan (UoM). Following extensive testing and deployment at a wide variety of organizations that were sponsors, ISDOS experienced increasing difficulty in providing a growth path, and the support needed by so many organizations that wished to use the toolkit. Universities are not geared up to providing and supporting such complex software as PSL/PSA when deployed in a number of very large organizations, all seeking further development and support. ISDOS and the UoM took a decision, in hindsight not a fortunate decision, to spin out ISDOS into a separate company. For a variety of reasons, ISDOS was eventually acquired, and its demise was followed by a sequence of mergers and acquisitions. PSL/PSA ceased to be available as a commercial product, although some of the original sponsors and customers of ISDOS Inc or Meta Systems Ltd have continued to use the tools.
