Michel de Lagausie  ( son of  François de Lagausie ).                  

I am a "Methods and tools" software engineer, on retirement.

I implement this Web site to spread this important and original Economic Value Theory.

Friends : economist, sociologist , philosopher, urban, ...  we are all concerned by this theory.

What are the impacts on your domain ?

Contact me:
For example, I propose to put on this web site, any report that you may produce to promote the diffusion of this theory.

I am not an economist, so I only be capable to facilitate the access to this theory, without the capacity  to participate strongly to the debate of the specialists.

   

Impact on a new theory of the Quality :

This approach of the economic value is reusable for an other complex concept, the concept of "Quality". I speak for example of the quality of a computer or the quality a simple artisan tool.

The French AFNOR definition of the "Quality" is (I resume) << ... the capability to satisfy the user needs >> This complex concept could be understood with also three points of view :

1. The usages of the tool : the level of the value judgment  ex: to be satisfied or not of this tool for this specific usage ?

2. The capacities of the tool : the level where we can measure the performance of the processes (ex: training process)

3. The structure of the tool : it is the level where we can measure the characteristics (size, weight, nb of functions, ...)

Remark : understanding these two concepts with the same approach permit to speak of the "quality / cost" ratio as a ratio of two Values.

   

For soft men:

Applying this concept of Economic Value to the Quality concept, should permit to build a more clear techniques to measure software quality.

I used to implement metrics involving for example Halstead measurements as well as Mc. Call metrics, but with a clear separation between Criteria and Quality Factors.

1. The usages of a tool : for example develop a web site and be satisfied with his computer and web site development software tool.
    
2. The capacities of a tool : The Quality Factors of Mc. Call ( ex. measure performances, the degree of usability, reliability, etc.)
    
3. The tool structure : measure Halstead metrics (ex: nb of operands, their nb of occurrences),
   or measure the number of lines of code, nb of menus, subroutines sizes, etc.

Using this point of view Mc. Call should have build a more clear method :

1. The Criteria must be only intrinsic characteristics of a software tool.
2. The Quality Factors must be only performances of using processes, (the capacities of the tool).
