Building a Successful Business Case for an Application Modernization Program
A Gartner® Report
"Applications and software engineering leaders often struggle to develop a successful application modernization business case. Those who succeed take a business-focused approach, splitting the work to target the most critical business capabilities, and delivering in multiple waves"
- per Gartner
"Application and software engineering leaders often find it challenging to create a modernization business case that convinces management – especially business stakeholders – to invest, with case weakness often stemming from taking an IT-centric approach. With an increasing number of ever more interconnected platforms in use today, it is no longer effective to approach modernization by focusing on one platform or one application at a time. The focus should be on the set of applications that support a business capability. Organizations often try to modernize the entire portfolio in one program, but are unable to execute such large, high-risk programs due to their long duration and half-hearted support."
As an applications and software engineering leader building a business case for application modernization, you should:
"Align your application modernization business case to business objectives, priorities and appetite for change by using four critical business case sections: problem statement, technology migration, project description and cost-benefit analysis. Prioritize critical business capabilities and identify associated applications for modernization by executing a business-led analysis of IT assets. Reduce disruption, risk, uncertainty and time to value by dividing the application modernization program into multiple smaller waves of work. Use business capability value to identify, prioritize and bundle applications into these waves."
