The reengineering journey: A holistic transformation
Reengineering Excel goes beyond simple upgrades; it involves rethinking how Excel is used within your organization, aligning spreadsheet solutions with business objectives, and ensuring that the new Excel environment is robust, scalable, and future-ready. This journey requires a holistic perspective, integrating Excel with your broader operations and technology infrastructure to achieve a seamless and successful transition.
Laying the groundwork: In-depth Excel data analysis
The first step in the reengineering journey is a thorough analysis of your existing Excel environment. This includes a detailed examination of your current workbooks, identifying critical workflows, and understanding the dependencies embedded in your Excel files. By mapping out these elements, you can better assess which components need modernization, which can be streamlined, and how these components will interact within the new Excel system. This analysis also helps to uncover hidden complexities, such as undocumented macros or complex formulas that could pose challenges during the transition.
