Understanding key issues


Controlling project cost

The knowledge gained from using ModPaaS reduces the scope of existing applications and refines the modernization disposition strategy. Right-sizing these projects reduces costs too.

Unmaintainable code lines

Over time, code can become complicated. We can streamline the code on three levels – source code file, paragraph / section and line of code – simplifying the maintenance of applications.

Lack of legacy system visibility

Full visibility, including business rules, reports, documentation and application categorization, puts you in control of your IT while ensuring it supports your organization’s initiatives.
