Use Agile Application Rationalization Instead of Going Big Bang

Your Challenge:
•An application rationalization assessment is time consuming and the resulting recommendation of a big-bang approach is often too expensive or risky for the business.
•Trying to achieve simultaneous buy-in from several business stakeholders with competing priorities is challenging.

Our Advice:

Critical Insight:
•Keep your assessment process light and Agile. Big-bang approaches with large teams are difficult to implement. Get initial dispositions quickly and then drill down.
•Aim for realization not perfection. The goal is to rationalize, not to realize some perfect state and become paralyzed in the analysis.

Impact and Result:
•Focus application rationalization on a single business domain at a time. This will limit the number of applications you need to consider.
•Use an Agile approach of starting at a high level of initial dispositions and then successively drilling deeper to run an impact analysis on those applications that are most appropriate.
•Keep the project team small so decisions can be made faster and more transparently.
•If necessary, integrate the Agile application rationalization approach with an appropriate funding group to obtain funding for the implementation phase.

Use Agile Application Rationalization Instead of Going Big Bang

  1. 1. Use Agile Application Rationalization Instead of Going Big Bang Don’t boil the ocean. Use a focused domain-based approach to continually achieve results. An application rationalization assessment is often time consuming and the resulting recommendation of a big bang approach is often too expensive or risky for the business. Additionally, trying to achieve buy-in simultaneously from several business stakeholders with competing priorities is difficult. Stay away from a big bang approach. Start with a specific business domain to achieve quick focus and then use an Agile approach to drive out your analysis and recommendations. 48% of organizations believe that there are more applications than the business requires. 76% of organizations indicate that modernization of their application landscape is critical to achieve business objectives. 72% of organizations do not have an excellent understanding of their current application portfolio. The third top strategy used by organizations to increase IT’s value to the business is application rationalization. Source: Capgemini. “Application Landscape Report: 2014.” <http://www.capgemini.com/resource-file- access/resource/pdf/capgemini_application_landscape_report_2014.pdf> Many of today’s organizations experience application sprawl over time. This monopolizes precious resources to support multiple applications that offer similar functionality and takes away from IT’s ability to support new business initiatives and focus on innovation. By some estimates, 80% of IT’s budget is consumed by supporting existing applications. Instead of taking the big bang approach of trying to rationalize applications over several business domains driven by competing priorities, focus on a single domain and rationalize the applications in that area. Then move on to another business domain and repeat. The goal should be to achieve some business value each iteration.
