Sales analysis - legacy coursework

This repository preserves coursework by Afsar Ali (Ali) on sales, promotion, discount, and profitability analysis. The source files date from 2016-2017 and the repository history ends in 2018. It is an evidence archive, not a maintained production system or a record of client work.

What is included

Project Source Input Preserved output
Cereal promotion and advertising analysis R Markdown CSV HTML
Furniture sales and profitability analysis R Markdown CSV HTML
Furniture profitability dashboard Shiny source CSV Hosted Shiny app
Financial-statement ratio exercise Source workbook is not present Not present PDF

The two R Markdown files identify Afsar Ali as author and BUAN 5210 as the course. The financial-statement PDF also bears Afsar Ali's name, but its exact course and embedded calculation workbook are not preserved here.

Analytical work represented

  • Calculated sales and volume measures and explored promotion, advertising, brand, and product relationships.
  • Examined profitability, discounts, quantity, product category, region, and time patterns.
  • Implemented a Shiny dashboard that filters and renders profitability, quantity, and discount views.
  • Completed a class financial-ratio comparison using 2011-2015 statements.

These artifacts demonstrate historical hands-on analysis. They do not establish production deployment, business adoption, or measured revenue or profit impact.

Reproducibility

The notebook inputs and generated HTML reports are checked in. The source calls the following R packages:

  • cereal analysis: tidyverse, GGally, gridExtra, kableExtra, plyr;
  • furniture analysis: tidyverse, gridExtra, waterfall, lubridate, plotly, zoo, kableExtra, Hmisc; and
  • dashboard: shiny, shinydashboard, ggplot2, tidyverse, plotly, rsconnect.

There is no recorded R version, package lockfile, session information, test suite, or CI workflow. The current audit did not re-run the notebooks, and the external Shiny app may require a hosted-service wake-up. Treat the checked-in HTML as historical output rather than proof of a current reproducible build.

Data provenance and use limits

  • MTP_Data.csv: 1,995 rows and 8 product/promotion fields.
  • D7_Office.csv: 9,994 rows and 19 order, customer-ID, geography, product, sales, discount, and profit fields.

The original publishers, collection methods, transformations, and redistribution licenses for both CSVs are not documented in this repository. Do not treat the records as current customer data or reuse them externally without verifying their source and rights.

Evidence-supported career statement

Built R and R Markdown coursework analyses of promotion, sales, discount, and profitability patterns, and implemented an interactive Shiny dashboard from an included retail-order dataset.
