Are legacy applications holding you back?

As organizations evolve on their digital journey, many fail to reach their expectations. Often these companies have application portfolios that include custom developed apps and legacy commercial apps that quickly become outdated and cannot continue to support necessary business innovation.

The Result

Custom solutions that were originally necessary are no longer relevant, as more flexible functionality exists within newer applications. These legacy solutions pose challenges for your organization.

First, it is difficult to find talent to maintain legacy apps. Newer workforce talent does not understand older code, and often has no desire to learn a non-market skill. Integrations are often troublesome due to instability inherent in older structures. Couple that with the fact that many legacy systems are riddled with security vulnerabilities, and you have a problem worthy of sleepless nights. 

So why haven’t these apps been modernized or replaced?  Often there is a perceived level of complexity that is not accurate. Perceived uniqueness is also an excuse. 

In reality, something must be done before bad things happen

The answer is simple: Modernize your application portfolio stack. You likely already know this. However, many IT Departments find it difficult to redeploy existing staff already working on other key business items.
