AI for Finance & Accounting
Module 5: Forecasting Assistance
Module Overview
Forecasting is both art and science. AI can enhance your forecasting process by helping structure analyses, identify drivers, stress-test assumptions, and communicate results. In this module, you'll learn to leverage AI for better forecasting outcomes.
Learning Objectives:
By the end of this module, you will be able to:
- Build budgets and forecasts with AI support
- Conduct scenario analysis effectively
- Create cash flow projections
- Develop revenue forecast models
- Communicate forecast assumptions clearly
Estimated Time: 1.5-2 hours
5.1 AI's Role in Forecasting
What AI Can and Cannot Do
AI Can Help With:
- Structuring your forecasting approach
- Identifying drivers and variables to consider
- Generating scenario frameworks
- Writing assumption narratives
- Reviewing forecast logic for gaps
- Communicating results to stakeholders
AI Cannot:
- Know your specific business drivers
- Predict the future accurately
- Replace your judgment on assumptions
- Access real-time data (unless integrated)
- Guarantee forecast accuracy
Your Role:
- Provide the data and context
- Validate assumptions
- Apply business judgment
- Make the final calls
- Own the forecast
The AI-Assisted Forecasting Process
- Structure: Use AI to organize your approach
- Drivers: Identify key variables with AI input
- Build: Create the model (you do this in Excel)
- Assumptions: Document and stress-test assumptions
- Scenarios: Develop alternative cases
- Communicate: Draft narratives and presentations
