Aggregated and mean data
The collection of data of a single measure of customer satisfaction does not indicate what aspect of their visit to the store customers are satisfied, or dissatisfied, with.
Customers may consider the price, design and quality of the goods, the comfort and layout of the store or the friendliness and product knowledge of the staff when scoring their satisfaction. Without knowing which aspects of their visit customers are satisfied with, it will be hard to know what to do to improve customer satisfaction.
Using the mean score may also make the data hard to interpret. For example, in Quarter 1 20X4, 50% of the customers are completely satisfied(a score of 5)and 50% of the customer are completely dissatisfied(a score of 1). This may be due to an error in collecting or compiling the data, but the mean score of 3 indicates that, overall, customers are satisfied, whereas 50% of them are completely dissatisfied. The calculation of the median or modal score may be preferable because this reduces the distortion to mean scores caused by very high or low scores.
Conflicting measures
When selecting measures to use in the balanced scorecard, care must be taken to select measures which do not conflict with each other. Otherwise, without further guidance, managers will not know which measure to focus on, or may simply ignore one measure and focus on another.
Several of the measures selected by the consultant may potentially conflict with one another. For example, in order to achieve a low stock out percentage, Veyatie may have to hold higher levels of inventory which may worsen inventory turnover. This could apply at the overall company level or at individual stores.
The financial measure of operating profit margins conflicts with some of the measures in the other perspectives. The total number of employee training days has been selected to measure the learning and innovation perspective. The cost of this training, at least in the short term, will reduce operating profit margins. Similarly, having a high market share may imply that Veyatie will have to be competitive on price, which will also lower operating profit margins.
