Streamlined & Intelligible Excel spreadsheets

OAK  is now available in two versions:

OAK Essentials – This edition makes available the four key functions of OAK in a simple, affordable package.

Summarize Generates reports on a model’s complexity as well as modelling risk factors.
Map Provides a visual representation of the model’s formula consistency.
Search Locates cells with specific attributes.
Compare Indicates what has changed from one version to another of a workbook/worksheet/range.

OAK Professional – In addition to the four Essentials tools, the full edition of  OAK provides another 28 advanced functions.
