A masterclass in continuous improvement reveals an unexpected truth: the biggest privacy risk in most organisations isn't malicious intent, it's simple over-collection, and Lean Six Sigma has been solving that exact problem since long before GDPR existed. Aakash Suri talks with David Hirst, a Lean Six Sigma Master Black Belt with a deep background in continuous improvement, process design and coaching, about where privacy, data protection and Lean Six Sigma overlap in the real world. They explore how "waste" in a process almost always means unnecessary personal data, why breaking down departmental silos is the single biggest lever for reducing risk, and how root-cause tools like value stream mapping expose just how little of a typical process actually adds value to the customer. KEY TAKEAWAYS Treat over-collection as the biggest form of waste in any process. David Hirst identifies overproduction, collecting more data than necessary or collecting it earlier than needed, as the costliest waste in Lean, since every extra piece of personal data stored has to be maintained, secured and eventually disposed of. Sort every process step into customer value add, business value add, or waste. Business value add breaks down further into whether something mitigates financial risk, is necessary to operate the business, or is required by law or regulation, such as GDPR. Anything outside those categories is waste worth challenging. Break down departmental silos to stop the same data being collected, stored and maintained multiple times. David describes how different departments in the same building often gather two-thirds of the same information in slightly different formats, multiplying both effort and privacy risk unnecessarily. Build psychological safety before asking people to expose inefficiencies in their own work. Employees won't surface waste or raise compliance gaps if they fear an improvement will cost them their job, so the goal is always to make more of people's roles, not to reduce headcount. Use tools like value stream mapping and root cause analysis to make inefficiency visible. When teams plot out how a process actually flows, value-adding steps often account for less than 5% of total lead time, exposing rework, duplicate approvals and unnecessary data handling that would otherwise stay hidden. QUOTES "Good process means we're not doing anything more than is necessary to advance the product or the service for the customer." "The biggest waste in Lean is overproduction... either we collect more than we need, or we collect it earlier than we need." "If the only tool that you've got in your toolbox is a hammer, then everything looks like a nail." "The more you get into it, the more you realise it's about the mindset." "Everybody should go home with the same number of fingers and toes that they came in with, but also they should go home with the satisfaction that they've done a good job for the day." FREE GIVEAWAY INFORMATION What is up for grabs? 1 day (9:30am-4:30pm) Lean six sigma training course for up to 12 delegates at Yellow Belt level to a customer - In person or Virtual depending on geographical location.

Lean is a methodology aimed at enhancing efficiency by making problems visible, allowing them to be tackled using Lean thinking, tools and techniques to deliver greater value to customers. Originating from the Toyota Production System, Lean focuses on continuous improvement (Kaizen), respect for people, and the elimination of the seven types of waste. It is perhaps more applicable today than ever to help organisations compete or deliver a higher level of service. Any sector can benefit from this training: corporate, non-corporate, public sector, charity, healthcare. The day will consist of the following: Introduction to Lean Brief history and current applicability of Lean The five Lean principles Introduction to key Lean tools & techniques Practical activities to demonstrate concepts Participants will receive a Yellow Belt certificate, giving them a stepping stone onto further belt courses to develop their knowledge. HOST BIO Aakash is a recognised Data Privacy leader who helps organisations navigate complex regulations with clarity, confidence, and common sense. Unlike the legalese-driven privacy pros who simply regurgitate the law, Aakash breaks down what the rules actually mean, translates them into plain English, and gives businesses three SMART, pragmatic steps to demonstrate real compliance.
