The document outlines a framework for prioritizing and planning the decommissioning of applications based on various criteria, including functional and technical dependencies, business criticality, and cost efficiency. It identifies different move groups and wave planning strategies to transition applications based on their complexity and interdependencies, aiming to optimize the transformation process. Additionally, the analysis highlights potential opportunities for application consolidation to achieve cost synergies and simplified management within the target landscape.

Applications Prioritization | GWIS Wave Planning for Decommission
Guiding Principles:
Applications with high RTB cost are considered for early decommission (wherever possible) to provide
synergies(47% benefits realized in wave 1 & 2)
Application performing similar functions have been consolidated for wave planning wherever possible to provide
business value realization
Length of a wave depends on the complexity of the applications in that wave
Interdependencies between GWIS applications have been factored into wave planning
Wave planning does not consider the current target state status of the applications

Medium complex applications. Planned for decommission in the intermediate wave
Applications with medium complexity are planned for early decommission in wave 1.2
and wave 2. Other few applications are aligned for later waves
Most of the applications are aligned for decommission in later waves as the
applications are either very high in complexity or the details are unknown
Aligned for decommissioning in later waves as the applications are either very high in
complexity or the details are unknown
Most of the applications are planned for wave 2 decommission since they are without
dependency. Other applications are aligned based on complexity
Applications outlined for fast-track decommission are prioritized for the initial wave
and those with high business complexity are aligned for later waves
