How to Value Stream Map (VSM) in Low-Volume High-Variation production

🎥 Ever wondered how to effectively implement Value Stream Mapping (VSM) in low-volume, high-variation production settings? In this TH-cam video, I explain that challenge, offering insights to help you optimize your processes. 🔄 If you're grappling with questions on how to navigate the complexities of measuring and improving efficiency in diverse manufacturing scenarios, this video is tailored to provide valuable guidance.
⚙️ Explore the nuances of VSM with a focus on your unique production environment. Learn how to:
- Use Product Families: Discover the benefits of categorising products into families, making your VSM efforts more meaningful.
- Prioritise Critical Products: Understand the significance of focusing on critical products to streamline your VSM approach.
- Balance Product and Process focus: Look into both product and process-centric views for a comprehensive understanding of your production flow.
- Identify Bottlenecks: Learn to assess total subprocess utilisation to pinpoint bottlenecks and optimize production throughput.
- Optimize Changeover Times: Minimise changeover times to enhance flexibility and responsiveness in a high-variation environment.

Hi Tom! Ive been meaning to leave a comment when you released this video.
Main purpose of the value stream map initiative is to drive TAT reduction and improve OTD.
We did a quantity-profit analysis to figure out which products to focus on.
Using historical data, we found out that we had a handful of processes that has a high idle time, which drove the TAT.
12:13 we do have furnaces and heat treat process and you're absolutely right that it's one of our bottlenecks due to high run time and high change over time.

Great to hear your experiences - I'm sure other viewer also love it when you share such things (we're all CI enthusiasts out here, after all).
Especially with these low-volume production runs, turnaround time and on time delivery are key indeed.
You'll probably have seen that OEE isn't all that useful for making impactful improvements, but flexibility, change-over time, and the like are really important.
Great stuff, thanks again for sharing.

​@@TomMentinkoh yes, definitely! OEE doesn't make sense when we have equipment that only has 11% utility rate 😂
