Quality Assurance For Legacy Systems Across
OS2200 Enterprise.

Presentation abstract The presentation
describes how SQA was applied on OS2200
environment at the WM-data Defense in the end of
80th and how it was redesigned in the mid and end
of 90th to meet challenge of the new millennium.
The presentation describes also how SQA is
applied today to meet challenge of the future.
The SQA system is an automated tool, designed to
improve the productivity of Development, Quality
Assurance and Operations staff. SQA does this by
automating routines that are usually handled
manually, for example the collection and tracking
of information. Many routine and error-prone
operations can be eliminated, and no manual
intervention is required.

Huge amount of money is invested in legacy of IT
systems.
Because of this and because the business process
is constantly changing, program maintenance is
and always will be with us. It is better,
therefore, to successfully manage this
maintenance and development in the most efficient
manner to the satisfaction of all.

Changes in the IT system
Accounting consists mainly of information about
which program instructions are changed and which
processing criteria are the basis for these
changes.
This applies to all changes which occur,
regardless of the size of the change.

Purpose
Meet management and audit requirements
Secure systems in production Improve the
development environment for complex
maintenance-sensitive IT systems
Save money (improve productivity)
