Following is the forward to this file. Complete copies of the survey file will be emailed to the respondants. Rick ---- PDLSURVEY.DOC Foreword ---- DDN-Based Ada PDL Survey 4 December 1985 Richard Conn A survey was conducted on the Defense Data Network in September to November 1985 to determine what PDLs were currently in use by members of the INFO-ADA and ADA-SW mailing list communities. It was expected that this survey would not be conclusive in any way since (1) the survey audience was limited and (2) of those who would receive the survey, only a few would respond. It was hoped that the survey would, at the most, indicate if a definite trend toward one particular PDL exists. I have concluded from the few (less than 10) responses received that a trend toward one particular Ada PDL is NOT evident. There is some indication that there is a desire to Ada PDLs internally, which will result in a lack of standardization.

Plus, it will (would?) be used on any of many other projects, of varying sizes, which we have bid. I am not sure, but I think at least one TRW project (at a non- California site) has used Intermetrics' Byron; at least, they intended to try it out. I appreciate your trying to so "measure" popularity or acceptability of various Ada-based PDLs, but as you suggest, this will be hard. First, many of the Ada-based PDLs are proprietary (esp. their suites of support tools), so they can not possibly be used by more than 1 company. Also, number of projects or, even better, aggregate dollar value or programs sizes, might be a better measure which you would have little hope of capturing. And, finally, it is certainly too early to start drawing objective conclusions about the successes & failures of these early usages (both due to future completion dates of large projects & inevitable improvements to each PDL & its tools). -- Hal Hart, TRW PS: I assume you are aware of the semi-yearly update of Ada PDLs status which Judy Kerner publishes in Ada LETTERS. It includes dozens of listings, & I know that she just early this month completed her own canvass of every entry. Although her new matrix probably won't appear in your mailbox for months, I suggest that you request an advance copy from her (2 electronic addresses above). **** RESPONSE TO QUERY **** Received: from nosc-tecr.arpa by CSNET-RELAY.ARPA id a002680; 27 Sep 85 11:45 EDT Date: 27 Sep 1985 0832-PST From: Contr22 Subject: Re: Informal Survey on Ada PDLs To: conn%ti-eg.csnet@CSNET-RELAY Reply-To: CONTR22@NOSC-TECR Received: from csnet-relay by ti-eg; Fri, 27 Sep 85 13:41 CDT At Magnavox, we are using the Byron language from Intermetrics for all AFATDS software.

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, it is about 130 pages right now and so if you could send me your mailing address I will forward it to you. I am always looking for criticism/comments. 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. I am very interested in the results of your survey since it relates to work I am and will be doing for Larry, and would appreciate your keeping me abreast of your findings. I am particularly interested in any comments you receive on structured English, and of course the explicit information I mentioned above (exceptions, requirements traceability, inter-unit dependnecies). The experiment is a competitively procured contract (RFP out now) expected to start up in January.

ANNA was described in the March issue of IEEE Software. We have been looking at how using a more formal Ada PDL affects what is presented at a PDR and a CDR, as well as how much better the final system looks. Currently we are in the middle of designing the system, we just had a PDR review. Christopher Byrnes The MITRE Corporation Burlington Road M. S.
