Stock reliability is a crucial issue for Leroy Merlin.
The present tools allowing to know the reliability of the stock of a store do not correspond any more to the needs nor to the expectations of the users in store nor to the headquarter of Leroy Merlin.

Developed an app that highlights stock status
and possible inventory actions.

Take into account the store (human) and central (business) needs
Provide a new business gesture without burdening those already present on a daily basis.
Create a simple application that communicates with other new applications / databases developed by Leroy Merlin.

Created the user surveys, to determine our target audience and to gain a basic understanding of our users. About 14 responses were recorded. And based on the responses here are the key insights presented below

The survey confirmed that user need the shop is in a physical state of product availability, as full as possible with the stock available in shop.

The tools is outdated and no longer corresponds to the new business processes.

The survey confirmed that lack of common terminology/language between warehouses, shops and suppliers (pallet, volume, line, linear meter, etc.)

30 to 40% of direct suppliers do not communicate delivery information well enough.

Logisticians are experiencing daily frustration due to a lack of reliability in stock.

Team members individually ideated and wireframed to address user pain points. Then we reviewed all sketches on a Figjam board. Based on the individual sketches I created a collaborative lo-fi prototype, categorizing Trust in stock user flow into Supervision, Stocktaking creation and Follow up flow.

• Get an overview of stocktaking progress.
  
• Go directly to stocktaking progress details.

Get details on the progress, time overview and performance of an stocktaking.

Have a view that lists all past, present and future stocktaking, with filtering.

Have a user path that allows the creation of a future stocktaking with several parameters.

We validated prototypes through heuristic evaluation and usability testing, refining design based on user feedback and behavior analysis.

📖 #1: Separate differents type of stocktaking
Simplify access to a specifique type of stocktaking.
🎯 #2: Use existing metrics
Use indicators with which users are already familiar..

The redesign improved UI readability of user interface by using existing metrics, simplifying elements and focusing on stocktaking that need to be monitored as a priority.

Mozaïc is Leroy Merlin's design system for using ready-made global components. However, for very specific needs, it's up to the teams to build their own components. This is what we did for some of them.

• Error rate in prepared orders Reduction in the error rate from 2% to less than 1% of orders processed, indicating an improvement in picking accuracy.
  
• Average order preparation time Average order preparation time reduced from 20 minutes to less than 15 minutes, reflecting improved efficiency.
  
• User satisfaction with the new tools User satisfaction score of 82% (from SUS) for the new logistics tools, measuring their ease of use and usefulness.

• Reduction in costs linked to overstocking and stock-outs 20% reduction in costs in the year following in-store implementation, demonstrating more efficient stock management.
  
• Improved logistics productivity 15% increase in the productivity of the logistics team thanks to better organisation and the use of more efficient tools.
  
• Stock reliability compliance Increase in the stock reliability rate to an average of 95% in 2023, with a target of 98% in 2024, ensuring compliant and accurate management.

The project allowed me to learn more about the design process within a large retailer like Leroy Merlin. I learned how to make better visuals with Mozaïc design guidelines, creating and contributing with a small library of components. I consolidated my approach and methodologies to work in collaboration with other teams at Leroy Merlin.
