Good engineering – Sustainable business

October 17, 2011 Leave a comment

Sustainable engineering of consumer products means a much reduced amount of production waste, careful choice of good commodity components, integration of technologies with robust and scalable performance , and in general designing for a life together with the customer rather than a brief financial transaction.

Below is a neat introduction worth watching before each valuable day of good engineering:

The meaning of Quflow & Perfeco

August 25, 2011 Leave a comment

QU as in qualification: meeting or exceeding expectations.

FLOW as in workflow: way of working to reach goals.

PERF as in performance: how good a function is compared to user expectations.

ECO as in economical-logical: how cost and resource efficient a design is compared to product targets.

All these aspects are intimitely connected with product quality: Quflow makes all qualities grow at a steady pace and Perfeco ensures those qualities perform well in all target systems.

The author and publisher of this site is Joakim Pettersson, an engineering physicist focussed on rapid product quality growth and benchmarking. His research and industrialization involvements are listed on the references page. Below is a magnification of his favourite mathematical expression – quality flow:

The reason this so beautiful [besides it being typeset by latex from $Q_leadsto$] is that the Q is a favourite mathematical symbol representing quality, and the flowy arrow has the mathematical meaning “leads to”:

Quality leads to <insert your favourite quantity here>.

Rapid prototyping and verification

August 6, 2010 Leave a comment

Quflow provides a rapid prototyping and verification environment where all intercomponent problem areas can be analyzed easily. This simplifies the industrialization process by enabling quick integration of new components while securing that user expectations and legal requirements are met. The Quflow environment can be used for modular development of all kinds of systems, and comes with free source code in Python. Example applications are included that use direct VISA communication or LabVIEW drivers to interface with the complete system under test.
