Susan Walsh is The Classification Guru, and for nearly a decade she has been fixing dirty data for businesses that depend on it. Her specialisms are data classification, supplier normalisation, taxonomy customisation, and data cleansing, with a particular focus on procurement and spend data. By bringing clarity and accuracy to messy records, she helps teams work more effectively and efficiently, and she uncovers cost savings through better spend and time management that support smarter, better-informed business decisions.

What makes Susan’s work distinctive is her methodology. She has developed a repeatable process to classify, cleanse, and check data for errors accurately and efficiently, preventing the costly mistakes that unclean data causes and saving clients days, if not weeks, of laborious manual cleansing and classifying.

Susan is equally known for how she talks about data. She cuts through the jargon and addresses the causes and consequences of dirty data in a way that is entertaining, engaging, and memorable, raising awareness through her blogs, vlogs, webinars, and speaking engagements, including her talk Dangers of Dirty Data at the DataTalks.Club conference. Her message is simple: data quality is not a chore to defer, it is the foundation every report, dashboard, analytics project, and machine learning model is built on.
