The pain

What it costs you today

In an operation with 3 to 5 source systems (CRM, ERP, NPS, marketing tool, ticket base) the weekly report to management is a manual collage: someone downloads the CRM CSV, pastes it into Excel, asks another to sum the sales figures, opens PowerPoint to insert the dashboard screenshot, and finishes with an 8-page PDF arriving at 11 am on Monday. The process consumes 2 to 4 hours of a senior profile every Monday, resources that could be spent on real analysis. The problem with the manual version is that numbers overlap: two reports with the same date and different metrics depending on who built it. The process audit asks for traceability and the answer is "Juan built it on his laptop." "I cannot quit because I am the only one who knows how to assemble the Monday report" is the trapped senior analyst confession. How much is it worth to free the senior from the Monday ritual?

The value

What changes when you have it

On day one the report arrives on its own in the management inbox every Monday at 07:00: it reads data from the N systems via API or SQL, builds a .xlsx with corporate formatting, charts per section and an executive summary sheet written from a template. The owner of the report is the operations leadership, which now decides with consistent data week after week. The visible output is the .xlsx file in SharePoint plus the automatic email with copy to the distribution list. A professional services firm with 12 business units replaced 8 manual reports with 3 automated reports and freed 32 person-hours per week. The investment pays back in the first month, factoring the hours recovered from the senior profile.
