Trend graphs make it easy to detect changes, and regional comparisons also require checking the measurement range and operating background. Areas, time periods or equipment constitute different areas. Even if the numbers can be displayed side by side, they may not be suitable for direct evaluation.

Indicator objectives

First ask whether the Kanban board is used for duty observation, cost verification or management analysis, and then select indicators. Different purposes require different update frequencies and query entries, and not all charts must be displayed in real time.

Comparison caliber

Year-on-year, month-on-month or regional comparisons require clear statistical intervals, measurement ranges and data integrity. When business activities change, the management effect cannot be directly judged by looking at the total energy consumption alone.

Explanation path

Each key chart should have an entry for equipment or business details, and the update time should be displayed. Kanban helps find abnormal clues, but you still need to check the collection status, operation records and production background later.

Scene verification

When comparing two areas, you can first list the respective measurement points and operating background, and then check whether they are comparable. Charts allow for side-by-side display and do not mean that it is possible to directly determine which area is more energy efficient or better managed.

Specific verification method

Before comparison, expand the list of measurement points in each area and check the unit and time; let an area lack sampling and check that the chart does not draw a true zero value; switch the running period to view the range description; the indicator total should be able to return to the original sampling, not just an unverifiable curve.

The chart provides the source, scope and operating background to facilitate staff to determine where the changes come from. Before comparable conditions are confirmed, the page should present facts and differences to avoid making causal conclusions for business personnel.
