French to English Bus/Financial Retail planning a retail concern

- rappel d'une contrainte forte du projet : les lots sont séquentiels, c.a.d. que tant que nous serons **en lot** Europe puis Asie, nous ne pourrons mener en parallèle que l'analyse d'écarts entre les besoins France et le Core Model. Ceci donc jusqu'en été 2008.

I can't quite get the sense of this... it's taken from a document concerning the setting up of a well-known retail chain in France (where, by the looks, it does not exist already). Clothing and other goods. Does it simply mean something like: 'while we are in production (?) for the France project, followed by the Asia project...etc. etc.? Or simply 'as long as we are working on France, followed by Asia.... ' ? It's actually not possible to tell from the rest of this document, which is quite short - I have others to follow, but have not received them yet. I can't think what else it could mean... seems too specific to use 'batch' here....
Any ideas?
