A software engineering research study has been undertaken to empirically analyze and compare various software development approaches; its fundamental features and initial findings are presented in this paper. An experiment was designed and conducted to confirm certain suppositions concerning the beneficial effects of a particular disciplined methodology for… (More)
The effects of human factors on "high-level" software properties–too intangible to quantify directly–can be inferred from the collective behavior of related "low-level" aspects.
This paper discusses (1) some general concepts of design languages, (2) the development of the specific design language denoted as PDL/Ada, (3) the specific features of PDL/Ada, and (4) some problems encountered and techniques used in defining PDL/Ada. An appendix shows two examples. Because of space constraints, each of these items can only be touched on… (More)
