### Business Task:



- Identify the coffee type with the highest sales and strategies to boost overall sales.



- Determine the top-performing employee in terms of sales.



- Assess sales volume to optimize inventory and prevent shortages.



### Process:



- I gathered and extracted data from an **Excel workbook** using **Python Jupyter Notebooks** and processed the data to ensure it was complete, valid, and reliable. (cleaning, manipulating, and wrangling) [see code](https://github.com/mrjxtr/Semi-Annual-Coffee-Sales-Analysis/blob/12d7dbcadcfac8bfce73a245ef6caad503c7ec47/updated_coffee_sales_clean.ipynb)



- Created **Sales KPI**, a **line chart** showing the **weekly sales trend**, a **sales-by-employee bar chart** to see **top employee performers**, and a **sales-by-coffee bar chart** to see **which coffee has the most sales**. [see image](https://github.com/user-attachments/assets/60c9faf9-d313-4edf-b4b9-ea483c95e097)



- Made the dashboard **dynamic** to filter specific data in the line charts and the bar charts when *clicked*. [see dashboard](https://public.tableau.com/views/Coffee_Sales_Updated/SEMI-ANNUALSALESDASHBOARD?:language=en-US&:sid=&:redirect=auth&:display_count=n&:origin=viz_share_link)



## Sales Performance Overview (Jan-Jun 2024)

- **Rebecca Edwards** and Diana Collins are key contributors to sales success. It may be beneficial to examine their strategies and consider ways to replicate their success across the team.



- The **popularity of Latte and Mocha** could indicate customer preference, and there might be an opportunity to further promote these products, perhaps through bundling or targeted promotions.
