Middle

User's Skill Level The user will be Jack. He has rudimentary knowledge of Microsoft Excel, but the system will be user friendly and will be very easy to use. It will be impossible for him to enter incorrect data as I will be using data validation. He or any other user will not be allowed to accidentally delete/edit headings, formulas, images etc. DESIGN Choice of software The system will be implemented using Microsoft Excel 2000. This software is idyllic as it includes many basic as well as advanced features which can be used in customizing the program. I have listed some below. * Can create a blank template * The capability to link price details entered in one workbook with another workbook through a lookup table. * The ability to format text, alter page margins/layout, add logo's etc. * Formatting, to help make the user clear, where to enter data. * Can use charting facilities * Macros to automate various functions within the workbook. * Auditing tools to help ensure that there are no errors in the workbook. * Ability to protect worksheets and workbooks so that the user cannot accidentally destroy formulas or headings; * Customized menus and toolbars. ...read more.

Conclusion

Each cell for vegetables for each month has been validated. A minimum value has to be 0.01 or more and the maximum value has been set to 99.9. Cash flow sheet In the cash flow sheet the user can enter data into most cells with the exception of cells with formulas, they cannot be edited. This also makes a 100% accurate cashflow. Macros The following macros will be used: Main Menu - clicking this button will take you to the Mainmenu worksheet Price List - clicking this button will take you to the Pricelist worksheet Cashflow - clicking this button will take you to the Cashflow worksheet Orderform -clicking this button will take you to the orderform worksheet Exit - Saves and closes all open workbooks Sales Figures - Clicking this will take you to the Sales Figures graph on the charts/graphs sheet Total sales - Clicking this will take you to the TotalSales graph on the charts/graphs sheet Security All the worksheets will be protected so that data can be only entered into unlocked cells. However I will not attach a password to the workbook or worksheets incase Jack forgets it. Therefore the workbook can be unprotected using Tools > unprotect. ?? ?? ?? ??
