In this document I will begin to explain why I have included the following features in my Exam Spreadsheet. The context is a system which you can order a window for your house or business.

Spinners - I have used spinners in the sheet 'Find area' in cell D5, as it reduces what the user has to input. This reduces the likelihood of input errors. Its large and intuitive style made it easy for the user to alter data easily, meaning users don't get confused about what to input in. Also, as the spinner is linked with cell B5, the most ignorant users will not input letters into this field.

Multiplication - I used the multiplication function in the sheet 'Find area' in cell E6. It will produce a more accurate calculation than a human would perform, and will automatically recalculate the area if the dimensions change. This saves time for the user as they don't have to repeatedly recalculate the dimensions. It makes it much easier to analyse different prices when you alter dimensions with spinners, whilst if you have to perform calculations your self, you wouldn't have a vague idea what your window will cost
