Excerpted from Systems Architecting, Creating and Building Complex Systems, Eberhardt Rechtin, Prentice Hall, 1991.

TECHNOLOGICAL RESPONSE I: TECHNOLOGICAL SUBSTITUTION

One of the most dramatic improvements in component quality has been the inon of many circuits onto a single microelectronic chip, replacing thousands of Individual electronic . . .

THE BASIC RESPONSE: MURPHY'S LAW AND ZERO DEFECTS

Murphy's law and zero-defect implementation share in a notable and important omission-neither mentions statistics nor acceptable quality limits (AQL). If something can fail, it will. Perfection, not acceptable imperfection, is essential at every step.

No matter that perfection is an . . .

Eberhardt Rechtin on the Challenge of Ultraquality

The Writings of a Systems Architecture Legend

Ken McCormack

Software Developer | Application Architect | Audio Engineer

February 05, 2018

In his classic (but criminally overlooked) 1991 book "Systems Architecting, Creating and Building Complex Systems," Eberhardt Rechtin discusses technical, managerial and architectural responses to the challenge of building ultraquality systems - systems that are of such high quality that they are impractical to certify by . . .

Rechtin on Ultraquality - The Challenge

Excellence Beyond Measure and the need for Ultraquality Systems

Ken McCormack

Software Developer | Application Architect | Audio Engineer

February 04, 2018

Continuing the complex systems architecture theme and discussion of ultra-quality systems, the excerpt below is taken from Eberhardt Rechtin, Systems Architecting, Creating and Building Complex Systems, 1991, Chap 8.

Several issues spring to mind today, particularly how the need for some ultra-quality systems continues to be driven by public . . .

Talk on Continuous Delivery Architecture and Practices

Nondeterminism, xUnit, up-skilling, TDD materials and debates

Ken McCormack

Software Developer | Application Architect | Audio Engineer

December 04, 2015

I did a talk recently at the Sydney Alt.Net Meetup on testing practices for Continuous Delivery.

The talk was an introductory tour of the Continuous Delivery ecosystem, as it relates to technical practices such as TDD (for example, xUnit Test Patterns) and software architecture for testability. You can find the slides on Slideshare.
