FAQ
Frequently Asked Questions
No, while common in sales, it is applicable to any time-series business data like production output, costs, or website traffic where tracking cumulative and moving annual trends is valuable.
The name comes from the approximate 'Z' shape formed on the graph when the three data series (typically starting high for cumulative, dipping for monthly, and ending high for the annual total) are plotted together.
Advanced spreadsheet software (like Microsoft Excel or Google Sheets) with charting tools can create one, though it often requires manual combination of three data series on one chart. Specialised business intelligence tools may have templates.
They are primarily used by managers, financial analysts, management accountants, and operations planners to monitor performance and inform strategic decisions.
