Final answer:
To measure sales growth at each location, a report incorporating the Huff Model alongside GIS and spreadsheet analysis is recommended. This report should combine retail site analytics with actual customer transaction data. Comparative analysis over time with economic indicators like GDP per capita growth can further refine the measurements.
Step-by-step explanation:
To measure sales growth at each location, one should run a report that assesses several variables. Using a tool like the Huff Model in conjunction with geographic information systems (GIS) and spreadsheet software can help in predicting the probability that customers at various distances will patronize a particular store location. This is crucial for retail site location analysts. The model considers store size, the desirability of goods, and the extent of competition to estimate the patronage level. Additionally, collecting data on current sales figures through methods like surveying customers' receipts at a grocery store can provide a snapshot of present sales, which can be used as a basis for measuring growth.
To refine the measurement further, comparing Annual Growth/Change in the GDP per capita can also be beneficial as an economic indicator that might correlate with sales trends. A well-structured report would incorporate these data points, track them over time, and compare them with historical sales data to generate a comprehensive outlook on sales growth at each location.
