Formula Auditing
 The formula auditing toolbar allows the
developer to determine both precedents
and dependents of a cell.
 Precedents are the cells that the current
cell refers to (points to).
 Dependents are the cells that refer to
(point to) the current cell.

Reviewers
 Have others review your spreadsheet.
 Make use of Excel’s ability to create a
shared workbook – one that is
accessible to multiple users.
 Shared workbooks may be modified via
tools on the Reviewing toolbar or via the
Track Changes command.

Data Validation
 The Data Validation command allows
the developer to restrict the values that
may be entered in a cell.
 For example, you can specify that a
numeric value be between 0.0 and 1.0
(i.e. between 0% and 100%)

Protection
 Protected worksheets allow users to modify
only a limited number of cells.
 You must first specifically unlock those cells
you want to allow the user to change.
 Then you must protect the worksheet. The
unlock is ‘stronger’ than the protect – odd.
 You can later unprotect the worksheet if you’d
like, and lock/unlock the cells.

Scenario Manager
 Scenario Manager enables you to
specify, and to view, multiple sets of
assumptions (scenarios).
 Scenario Summary compares the
effects of the different scenarios to
one another by displaying result
cells.
