Jeff and Neal have hired an experienced executive to run the company and will be pushing hard to broaden the base of support for the SBM methodology outside the Macintosh world. I am reluctant to give more details, as by the time you read this MADACON will be over, and SBM International is sure to have finalized their shipment and pricing schedules. On the business side, the VDL series is reasonably priced, with the entry-level Companion product priced around $75. The Teamware version, as its name implies, adds multi-user support through the use of DAL and an ANSI SQL database. The Professional version adds the SBM calibration techniques (synthesis, correlation and synchronization) which are used to meld your various scenarios into a cohesive whole. (Here, "real world" means not just individual people, but also the manner in which those people work together to do their jobs.) Companion provides the basic drawing tools needed to create and manipulate VDL scenarios. SBM is based on the use of a visual design language (VDL) to, literally, draw up the scenarios which describe how an application will interact with the real world. The other two, VDL Professional and VDL Teamware, add additional features of SBM, as well as multi-user capabilities. VDL Companion is the first of three products in the VDL series. Unable to find an existing CASE vendor willing to faithfully implement SBM, the authors chose to produce it themselves (with the assistance of other MacApp programmers). Jeff gave us a preview of VDL Companion, a CASE tool which implements the design methodology which he and co-author Neal Goldstein first described in their book Developing Object-Oriented Software for the Macintosh. The December WAMADA meeting was host to Jeff Alger, co-founder of SBM International. March 93 - Affiliate News Affiliate News John MacVeigh
