Entering a new brand requires a choice of products and a preparation of the service. The store must be able to explain the proposal and know the conditions of supply. The first collection can be read as a limited trial, with explicit questions about the response of customers.
I propose to choose a set that makes the brand understandable without committing resources disproportionate to the available knowledge. Too limited a selection can misrepresent it; too large a selection can create stocks that are difficult to interpret. The comparison depends on the format of the store and its audience.
Let's imagine a new line of accessories proposed next to known products. The applications received can show which features are of interest and which require explanations. The willingness of the staff to present the line also influences what the evidence allows to observe.
The review compares sales, demands, and work needed. The initial result does not automatically demonstrate the behavior of subsequent seasons. A first collection is useful when it allows you to understand if there is a plausible link between proposal, store customers and resources required to support it.
