Knowing what your business is doing today is one thing - knowing what it will do tomorrow is another. It's not just a matter of statistics: it takes good information and good judgment.
Short term, you need forecasts that allow you to manage short term demand, to minimise inventory and maximise customer service. For the medium to long term, you're looking at product life cycles and keeping an eye on the competitive environment, to support sales and operations planning and budgeting.
Accurate forecasting demands the big picture - it needs information from sales, from brand managers, as well as good analyses of past performance. And that leaves most spreadsheet-based processes struggling.
Investigator II has the real-world sophistication needed to produce forecasts everyone knows they can rely on.
