To depict the distribution of customers and product preferences, tables and charts were made. To find any notable connections between sales and client preferences throughout several time periods (seasons), inferential analysis was carried out.

light on the most popular products aiding in inventory management and further development.

could be a relationship between price and the quantity of products desired. Nevertheless, other
key findings include;
Seasonal Sales Trend and Pattern:
The analysis revealed distinct seasonal sales trend and pattern, with a significant increase in
sales during Rainy season and a gradual decline during the Dry season.
Popular Products:
The top two most popular products are Milkshake and Smoothie accounting for approximately
72% of total sales. Additionally, customers show a strong preference for Milkshake.

● Dry Season Rainy Season
Figure 1 displays a line chart illustrating the fluctuating seasonal sales for one-year period. The
chart clearly depicts the high sales pattern during the rainy season, followed by a gradual decline
in dry season. This visual representation emphasizes the importance of focusing efforts and
optimizing operations during the rainy season to maximize revenue. This indicates that
customers are more inclined to purchase these products during rainy season, aligning with
expectations for a seasonal product. To capitalize on this trend, the business should focus on
targeted marketing campaigns and promotions during the peak rainy period i.e. July as shown
in Figure 2 to maximize revenue. Additionally, efforts should be made to optimize operations
and inventory management during the off-peak seasons to maintain a steady flow of customers.

Figure 2: Seasonal Sales Trend with Peak Period
The analysis of the seasonal sales trend with a peak i.e. figure 2, reveals a consistent trend of
higher sales during rainy season especially July, followed by a gradual decline in dry seasons.
This is further shown in figure 3, where there is a pattern in which sales consistently increase in
sequence in the first seven months and then decrease in sequence in the remaining five months
with December and January being the months with lowest sales.

To further confirm if the relationship between the products and the seasons occurred by chance,
a Chi-square Test was conducted, analyzing the observed and expected values. If the P-values1 is
greater than the significance level of 0.05 then the relationship could have occurred by chance,
when less than its otherwise.

⸫ (P-Values = 0.000000000000023 < Significance Level of 0.052)
So, there is a significant relationship between the four product and the two seasons. Also, the
relationship didn’t occur by chance so, the increase and decrease of these product was as a result
of rainy and dry season respectively.

Figure 4 represents a chart illustrating the distribution of the products, with milkshake and
smoothie constantly desired throughout the year. Also, there is a pattern- these products
consistently increase sequentially in distribution in the first seven months and then decrease
sequentially in the remaining five months. Milkshake and smoothie collectively make up
approximately 72% of total product distributed or sold as seen in the pie chart in figure 5 and
the products with most revenue as shown in figure 6.

products while also exploring opportunities to introduce new and unique product to attract a
broader customer base. To cater to this demand, the shop should ensure a consistent availability
of these products while also exploring opportunities to introduce new variations of the seasonal
product to add excitement and variety to the menu.

RECOMMENDATIONS
Since all products were sold at the same amount of price this report couldn’t establish if there
was a relationship between price and the quantity of products desired by customers. However,
to establish a relationship, it was recommended that the prices of less desired/popular products
should be reduced. Based on further analysis and interpretation of the data, the following
recommendations were suggested to optimize the operations and maximize the performance of
the business:
Seasonal Marketing Campaigns:
Develop targeted marketing campaigns that align with the seasonal sales trend. Increase
promotional activities and advertising efforts during the peak rainy months to attract more
customers. Consider offering special deals or seasonal promotions to capitalize on increased
demand. Additionally, during the dry seasons, focus on creative promotions, and price discount
to maintain customers and boost sales.
Menu Diversification:
The business should introduce new and unique flavors to cater to a broader range of customer
preferences (cocktail and smoothie). Conduct regular market research to identify emerging
flavor trends and incorporate them into the menu. Offer a platform for customer reviews and
suggestions. Additionally, regularly review the menu to ensure a balance between all products.
Enhance Customer Engagement:
Implement a customer loyalty program to reward and incentivize repeated visits. Leverage
technology, such as a mobile app to make it convenient for customers to participate in the
program. Additionally, engage with customers through social media platforms.
Optimize Staffing and Inventory:
Utilize the insights from days of the week sales pattern analysis to optimize staffing levels during
peak days. Ensure that there are enough staff members available to serve customers efficiently.

Additionally, closely monitor sales trends and adjust inventory management accordingly to
prevent stock outs during Sundays and Mondays.

stay informed about their offerings and strategies. Identify areas where the business can
differentiate itself and capitalize on its unique selling points.
Gather Customer Feedback:
Implement mechanisms to collect and analyze customer feedback consistently. Encourage
customers to provide feedback through online surveys or suggestion boxes.
