A network of retailers brings together businesses with different characteristics. Common purchases and services can offer advantages, while the conditions of the territory require local attention. Management must make the boundary between these levels understandable.

A hypothetical example is a common assortment that does not respond to all purchasing habits. I propose that we distinguish the shared core from the needs that require local assessment. Workable solutions depend on the actual agreements and rules of the network.

The comparison should use relevant information: customer requests, rotation, margins and logistics costs. A local exception can produce benefits and complications for other subjects. Understanding both effects makes it possible to discuss the proposal without reducing it to a personal preference.

Coordination also needs time. Constantly changing conditions makes it difficult to arrange purchases and deliveries; ignoring important signals can keep an unsuitable offer. I propose a periodic path for requests for modification, with understandable criteria and feedback. The management issue is to find a verifiable balance between the benefits of sharing and the ability to respond to differences, avoiding assuming an identical solution for each territory.
