Sir; re When Plans are Shelved', (The Grocer, July 20, p32), my view is that all parties have a lot to learn about improving compliance. Brands and retailers alike have a joint responsibility to maximise compliance instore, and provide stores with the suitable tools to achieve this. The POPAI project team is breaking POP production into the component parts, such as brands, design, production, fulfilment, merchandising and research to name a few, to investigate how each part can make improvements to POP production. If improvements were made to each part of the process, even small gains in implementation would result in significant uplifts for both brands and retailers. It is therefore in everyone's interest to work collaboratively to develop a best practice approach to compliance. The final point to note is that the POPAI project is looking at both temporary and permanent POP, and is intended to cover all markets, not just grocery.
