Worksheet

Modernisation decision worksheet

A worksheet with a row per module of the old system. Columns: what it does, who uses it, pain level, tables owned, integrations, chosen route (keep, refactor, replace or retire) and move order. A final block lists rules found only in daily use, such as odd rounding.

Name: ______________________   Business: ______________________   Date: ______________

Scroll the table sideways to see every column.

Cross out or rewrite any heading that does not fit your business. From the guide “Legacy application modernisation: rewrite or refactor”, www.gullysystem.com/blog/legacy-application-modernisation-rewrite-or-refactor
