What can the data tell me?
What should I do?
How can I increase revenue?
Precise Questions
How many Xbox consoles will we sell
during Christmas in France?
Which customer is likely to leave for a
competitor?
Four Questions Machine Learning can Answer
Regression Anomaly Detection
Predict a number Find unusual items
Clustering
Find groups/patterns
What will product revenue
be in Jan in France?
What is propensity of
customer to churn?
Find similar customers
who use cloud products.
Identify fraudulent
expense report filings.

EXAMPLE CUSTOMER QUESTIONS
Situation:
A competitor is targeting Microsoft customers and trying to
convert them to their own solution
Business Impact:
• Each customer loss to this competitor is $1 mil. lost lifetime revenue
• Each 1% of market share lost is $190 mil.
Question:
Can we predict the next customer conversion to this competitor before it
happens?

Financial Forecasting
Harvard Business Review, August 2016
“Forecasting is the third rail of business. Few companies are really good at
it, and there can be big penalties for being wrong. In fact, a survey of more
than 500 senior executives showed that only 1% of companies hit their
financial forecast over three years, and only one out of five are within 5%.
Overall, companies were off by 13%, impacting shareholder value by 6%.”
Machine Learning Forecasting: Project Delphi
Challenges in Finance:
 Inefficient planning and forecasting process (slow)
 Productivity: man hours required to generate a forecast
 Accuracy
 Human bias in forecasts erodes executive trust
VP Machine Learning agreed to pilot a project with Microsoft Finance in Central Finance
Goals
Provide a strong unbiased and automated baseline forecast to FP&A professionals who can
apply their domain expertise and adjust it to create a final revenue forecast
More frequent forecasts to give finance ability to respond to the business (enabled through
automation)
What we learned
• Continuous improvement system (new data sources, model refinement etc.)
• Strong partnership with finance and data scientists with shared goal of accuracy
• Finance has important business insights to help inform feature selection.
• Some one time events cannot be learned by machine. It remains critical for
business to judge the final forecast.
• IT required enhanced security for enterprise financial data in the cloud.
We built it into platform
• Explain-ability of results is crucial for adoption. Build driver-trees. Educate finance
on machine learning
