In this month's column we revisit a product that was reviewed in one of last year's issues — Alliance/MFG for Windows. It is not the practice of this column to re-review a software product so soon. However, it was decided to make an exception for this product. The reason is that during the process of writing the first review, Alliance Manufacturing Software International released a new and far more powerful version of its product. The review that was published last year covered Version 2.2. In this review, we examine Version 2.3.1. As always, if you would like to contact the software editor, you can do so by contacting Steven A. Melnyk either by phone (517-353-6381) or by e-mail ([email protected]
