Jane was a wizard with Microsoft Excel. If you were a friend of Jane, it is VERY likely that at some point you asked her for advise on a spreadhseet related matter.
Complicated formulas? Ask Jane.
Making a budget spreadhseet with automated formulas that automatically calculates stuff? Ask Jane.
A Gantt chart that automatically updates itself when you change a detail? Ask Jane.
She did not know this because she knew Excel in detail. She knew this because her mathematical brain realised that there must be a way to capture your requirement in a formula. She would think of that formula and then seek a way to implement that formula in to Excel.
Many times I would ring her from work with a quick question about a problem I was having. She would usually solve the problem for me whilst I was still on the phone. In exceptional circumstances, she would call me back a few minutes later with the answer.
This evening, I am trying to put together a cleaning rota for my shared house. There are 5 tasks and 5 rooms/occupants. Easy enough I hear you say.
However, there are 2 bathrooms. Bathroom 1 is only used by rooms 1 and 2. Bathroom 2 is only used by rooms 3, 4 and 5. So those cleaning tasks are fixed. Leaving the other 3 jobs to be allocated fairly. Obviously the problem is that bathroom 1 only has 2 people cleaning it and bathroom 3 is on a 3-person cycle.
Jane would know how to do this. She would first think of a formula that would fit this pattern. Then she would look at how to implement this formula in Excel. She would have scoffed at my method of doing it by hand.
Never thought a spreadsheet would break my heart.....
