Welcome to the Financial Modeler's Corner (FMC), where we discuss the Art and Science of Financial Modeling with your host Paul Barnhurst.

Financial Modeler's Corner is sponsored by the Financial Modeling Institute (FMI), the most respected accreditation in Financial Modeling globally.

Lyndsey Weber, a seasoned expert in financial and supply chain modeling join us this week for a lively conversatio on both financial and supply chain modeling. She recounts her experience with some of the worst models she has encountered, the lessons learned, and the importance of organization and design in creating effective models.

Lyndsey shares her journey from ExxonMobil to Quantrix, offering a deep dive into the art and science of financial modeling.

Key takeaways from this week's episode include:

Having a well-defined structure and approach is crucial for creating and maintaining effective financial models. Poorly organized models can lead to significant challenges and inefficiencies.

A horror story about inheriting a model filled with bad practices, including hidden reference cells and broken VBA code. The experience teaches her the value of starting over and building a model from scratch with best practices.

The importance of understanding stakeholder needs, both emotional and practical, and designing models that cater to these needs. This approach helps in building models that are not only functional but also user-friendly.

The benefits of using Quantrix over traditional Excel, highlighting features like always-on pivoting, natural language formulas, and role-based access, which enhance efficiency and collaboration.

One of Lyndsey's key pieces of advice is to prototype models on paper before building them. Mapping out inputs, outputs, and key calculations in plain English helps in creating a clear and effective model structure.
