Watson & Walker, Inc.

Cheryl Watson has been using and explaining mainframe operating systems since 1965. We at Watson & Walker, Inc. offer practical mainframe performance and measurement advice. Through our paid electronic publication Cheryl Watson's Tuning Letter, which comes out six times a year, we assist system programmers, capacity planners and performance analysts world wide using the IBM z/OS (previously the OS/390 or MVS) operating system. Our goal is to provide vendor-independent and very practical assistance and training, keeping our customers up-to-date and saving them valuable time, money and resources. We also offer two software products, BoxScore and GoalTender.

Please review all our offerings below, and while you're at it sign up for our free "Cheryl's List", a periodic emailing which contains such things as notices of publication dates, brief summaries of recent newsletters, news of software releases, and similar information.

BoxScore is our set of SAS programs which show you the difference in CPU speed and CPU capacity after a hardware change, a software change, a change in LPAR configuration, or a tuning change. For instance, we identify the stable job steps or transactions that most benefited from the change and also identify the job steps or transactions that suffered the most (or benefited the least). Click here to find out more.
