EY teams have successfully implemented a Client Zero model using IBM Apptio, demonstrating that transformation requires more than just deploying software. The approach combined the platform with a redesigned operating model, ensuring it could meet the needs of different functions while maintaining enterprise-wide consistency. The Enterprise Business Office worked closely with teams to clarify responsibilities and harmonize processes where possible, leveraging IBM Apptio’s flexible architecture to support both standardization and customization.
The rollout followed a structured process: reviewing current processes, configuring IBM Apptio, training users, and running old and new systems in parallel until the transition was complete. Cross-team leaders established clear roles, accountability, and governance, fostering collaboration between Finance, the Enterprise Business Office, and business units. This practical transformation playbook emphasized that technology alone is not enough, success depends on aligning work, roles, and decision-making.
Change management was critical, as teams had to adapt to new ways of working. EY teams recognized the resistance to change and provided support to help employees transition smoothly. The model also streamlined planning and budgeting activities, reducing manual tasks and enabling employees to focus on higher-value work like strategy and analysis.
As confidence in the model grew, it expanded across various EY member firms and functions, including Enterprise Technology, Information Security, and Supply Chain Services. This scaling helped refine the approach and provided practical guidance for clients. The resulting Client Zero playbook integrates platform configuration, process harmonization, governance, and adoption, all grounded in EY’s own implementation experience.
