Consolidation and Remediation

As part of making legacy systems ready for Year 2000, most were remediated to transform the logic to use modern, structured approaches. However, there are still some systems that exhibit unstructured characteristics. They may use older versions of languages and not take advantage of modern systems architectures. Such systems may each have different styles and patterns in their structure. This is especially true for systems that came from a previously separate business unit or an organization that was acquired. Moreover, such systems are likely implemented in different legacy technologies.

Client Situation

Maintaining and supporting legacy systems that are unstructured or are in diverse technology environments puts even more strain on scarce legacy systems experts. Additionally, the costs of maintaining systems in diverse environments are higher than if the systems were consolidated. This situation is characterized by:

• multiple applications that are limited in scope or functionality
• separate databases that contain only a subset of the enterprise view
• complex systems that would be difficult and expensive to consolidate, or
• applications or data in different technology environments.

Such systems typically represent stove-pipes of isolated or incomplete functionality.

IAI's Solution

IAI works with clients to remediate and consolidate legacy systems portfolios. IAI remediates legacy systems to be well-structured using current language versions, constructs and architectures. In-line code is converted to reusable object-oriented code. Furthermore, IAI consolidates databases and applications into integrated, cohesive systems. Additionally, IAI can add new or modify functionality in the consolidated system to implement new or changed requirements.

Value of this Approach

By remediating and consolidating legacy systems, organizations reduce the number of separate technologies being supported in their architecture. This reduces complexity and cost of maintaining the legacy system portfolio, enabling scarce resources to focus on higher priority activities.
