  5. SERVICE 03 Scope & Terms One symptom, or a limited

    group of related processes, is the unit; scope and verification method are fixed before fixing begins. We fix formulas, pivot tables, data imports and connections, SQL, and execution settings. For macros, we identify what they do but do not rewrite them. Targets are Excel-based aggregations and SQL / Python extraction and transformation. Modifying core business systems or redesigning the source database is out of scope. If a different cause is found, we present what was confirmed and agree on next steps. What to share when you contact us Tell us the target process, and what changed since when. Please prepare the relevant Excel files, SQL, programs, settings, and previous outputs. Data handling: Received data, SQL, Excel files, and settings are used only for this engagement, never reused elsewhere. Return or deletion after completion is agreed in advance. © kawakamisekkei Inc. 05
