>Hello!

>     I believe we met at the IEEE Ada as a PDL working group meeting
>in Clairmont, California earlier this year ... I was representing 
>Harris Corporation.  I was interested in your PDL survey for two
>reasons:  1) I am currently doing work for Larry Lindley, and
>2) I can give you some information on PDL usage at Harris
>
>     Based on Christine Youngblut's findings in Larry's survey, I have
>been desigining an experiment concerning the use of Ada PDLs for the
>STARS Methodology Team.  We are interested in the effect of PDL
>characteristics on process and product quality.  We have 
>decided to look at the effects of including some specific information
>regarding requirements traceability, exception handling, and inter-unit
>dependencies, the use of structured English in combination with Ada,
>and the provision of special templates geared for the particular design
>methodology to be used -- in this case Object-Oriented Design as
>defined by Booch.  The expeirment will consist of four teams of four
>people each for six months, where they (each team) will design the 
>same problem using a different PDL, and implementing the problem in
>Ada.  Depending upon the results of the first phase, there will be
>a second phase of the same length with two PDLs.  If you are interested
>I would be happy to send you a copy of the plan I prepared for Larry,

>     Although I am soon to be leaving the company to work for Software
>Productivity Solutions, I can tell you a little about use of PDLs, 
>especially Ada PDLs, at Harris.  Of course, the Harris Ada PDL has
>been used the most on a variety of projects.  Because it is a complex
>PDL supporting a very sophisticated methodology, it has not always 
>been well received.  In addition, we used the PDL/Ada from IBM 
>on a project.  No other Ada PDLs have been used at Harris, although
>Caine Farber Gordon PDL/81 has been used and there is talk about
>looking at their Ada style.
