Forecasting and Capacity Analysis for Future Dates, Projects, and Resource Names

Hi guys,

I am running into circles with trying to figure out this issue. I am wanting to automate our current capacity planning tool for my team and want to generate some sort of forecasting ability with the forecast formula. I have heard that the newer versions of Excel contain the forecasting sheet tool, but I don't have it at work.

My goal is to forecast hours allocation for future weeks and use actual hours for the weeks that have already completed. The tricky part is that the hours allocation for each person are also set up by project. This means each person has multiple projects and for those projects that take place in future weeks, I want to be able to forecast accurately without modifying anything for actual hours.

Here is my progress so far:

<today()-7,[@[sum of="" hours]],forecast
=IF([@[Week Of]]<TODAY()-7,[@[Sum of Hours]],FORECAST(

However, this does not take into account multiple projects or people into consideration whatsoever. If someone could please help me create a forecasting formula that factors in multiple people, projects, and actual and future dates, I would greatly appreciate it. Below is a sample of what I am working with right now. The forecast calculation would theoretically go after the "Estimated Hours" column in a separate column.

Copy formula down without changing references
If you have =SUM(F2:F49) in F50; type Alt+' in F51 to copy =SUM(F2:F49) to F51, leaving the formula in edit mode. Change SUM to COUNT.
