The Lot Number Generator project focused on enhancing manufacturing efficiency by reducing waste and improving traceability. Through user-centered design, we developed a streamlined solution that integrates seamlessly with existing systems, ensuring accurate lot number generation and compliance. This case study highlights the design and implementation process that led to a highly effective and reliable tool.

What is A lot number

A product lot number, also known as a lot code or batch number, serves as a special ID given to a particular batch of a product while it's being made. 

So, what’s the problem?

If a final product ends up with the wrong lot number, fail to pass quality control checks. Unfortunately, there's no way to fix this mistake, and the product can't be used. This not only disrupts the manufacturing process but also adds to production costs and has a direct impact on the environment.

The challenges

In the past, users relied on notebooks and Excel spreadsheets as primary means of tracking and storing lot-number data. The goal was to create a user-friendly, self-managed tracking system that minimizes human errors.

The key challenges and requirements are as follows:

• Users are used to the manual system for many years; they need a straightforward approach they can understand. 
• The human error may still be there because of possible misusing the new system/ app.
  

Targeted state

Here are the solutions we derived after talking to production managers and employers:

1. Simplify complex processes by moving them to the back-end, keeping the front-end focused on shorter, more straightforward tasks.

2. Enhance clarity and readability of all elements.

3. Introduce visual indicators for each process step.

4. Implement Bluetooth scanning for the final numbers to reduce errors associated with manual entry.

5. Employ a pin code system to ensure and verify the accuracy of the process.
