Excel Model Makeover 3 - Reducing Update Time

Excel Model Makeover 3 - Reducing Update Time

The course is presented in four parts.

First, the course introduces a business case of a “system updating” model that unintentionally includes all the hurdles to prevent fast update from the financial system. The model takes a staff 3+ hour to update the Excel reports for just 1 round of changes from the system, and what’s worse, system changes are twice or three times per day! So how to design the system updating model so that we can get “instant” updates from the system to the final presentation!

Next, the course will demonstrate how the author has overhauled the old model so that it:

o Reduces the system updating time from 2 hours to 1 min, and

o Reduces the presentation updating time from 1 hour to 2 minutes!

Third, the course explains 4 ways of reporting from a Financial System, but focuses on last 2 of them:

o Extract “reports” from the System

o Extract “data” from the System

Last, we demonstrate the 6 Dos and Don’ts in building system-updating and presentation-updating models. Some of the best practices are:

o Do NOT extract “individual report” from the system, opening the can of worms of huge manual work. Rather, DO extract the complete “data” from the system for automated reporting

o Do NOT copy/paste source data into the reporting file

o Do NOT cleanse data manually before calculation

o Do NOT manually key in entity name to generate report
