Well, if the users don't know about forecasting, let us hope that the consultant who implements their DP for them knows what he is doing.

Normally, when forecasting is new to the users, you let the system pick the forecast using Automatic Model Selection.

During auto model selection, each forecasted object is first initialized, then analyzed, then forecasted, individually.

No problem; just pick one of the simplest models, such as 'Constant' or 'Trend'. You already said that the client's users are not familiar with forecasting, so they don't really have any business requirement to fill; they won't care as long as they get a forecast.

I recommend that you not lose a lot of sleep on this issue. This is not like other implementations you may have done, where the results must strictly meet certain business rules. In the end, the output is just a forecast, a prediction of the future. The forecast will be wrong no matter what you do, since humans cannot predict the future. At least the ones that I know cannot......
