WHITEPAPER - Excel and IDIOM
Date: 20/10/2017
If the ultimate purpose of a calculation model is to manage real-world data in a transactional context, then an early transition from the very agile but ultimately limited Excel approach to an IDIOM Decision Manager multi-purpose/multi use approach should be considered: To increase run-time scalability, the calculation scope of the models, and the transparency and auditability of the 
modelling process; To allow automated testing and version management; To protect calculation IP; And to deploy calculation IP ‘without fingerprints’ into any production application, for use at any scale.
