How far ahead does your company plan?

The Guardian have reported that ‘French champagne house Taittinger plants first vines in English soil’. It will be interesting to see what they produce against their very exacting standards. However we may have to be a little patient as the first sparkling wines will not be ready until 2023. Taittinger are certainly planning a long way ahead but obviously need this lead time to get the product they want. I would be interested to see how their forecasts are looking and what system they are using to produce them. How far ahead does your company plan and could your planning system let you forecast 6 years into the future
