Language design and standardization

As Ada 9X unfolds, it is valuable to examine the evolution of Ada-83 to determine the strengths and weaknesses of both the design process and the language.
Ada is the outgrowth of the DoD Language Standardization, Convergence and Modernization program, led by Bill Whitaker and begun in 1974. A broad spectrum of users were involved in setting the original goals for the language which were:A usable language for real-time embedded systems
A precisely defined and well-controlled language
Improved software reliability and maintainability
Commercially available compilers and programming systems
An end to the proliferation of unique DoD languages

David Fisher led the transformation of user requests into specific technical requirements for the common language.
The goals of Ada 83 have been achieved. In the actual use of any language, however, it becomes clear that some users' needs were overlooked in the original goals, some might have been overly optimistic, some are right on target, and others are no longer appropriate. As a result, expectations for the language change.
What Ada 9X must accomplish is the fine-tuning of the language to meet expanded expectations without creating difficulty for current users. The revised language must be upwardly-compatible.
Using an approach similar to that which was so successful in the original creation of Ada, Ada 9X is listening to the needs of the general user community; is determining, through the Requirements Team, which are the most important; and is mapping the required changes to the language. One of the keys to achieving a consistent language is oversight by a single, principal designer. In the case of the original language this role was filled by Jean Ichbiah; for 9X it is being filled by Tucker Taft.
We fully expect Ada 9X to be the best choice for software applications ranging from real-time embedded systems to large distributed information systems; and, we hope, to become the most popular programming language worldwide.
