Case Study: Practical Implementation and Numerical Analysis

Company Overview:

• Name: KARAVAS AE
• Industry: Manufacturing and distribution of consumer goods.
• Employees: 150
• Annual Revenue: €10 million

Expense Ratio Analysis

Initial Data:

• Total Annual Expenses: €6,000,000
• Annual Revenue: €10,000,000

Calculation:

Expense?Ratio=(Total?Expenses/Total?Revenue)×100

Expense?Ratio=(€10,000,000€6,000,000)×100=60%

Interpretation:

• Expense Ratio of 60% indicates that KARAVAS AE spends 60% of its revenue on expenses.
• Goal: Reduce the expense ratio to improve profitability.

Liquidity Ratio Analysis

Initial Data:

• Current Assets: €4,000,000
• Current Liabilities: €2,500,000

Calculation:

Liquidity?Ratio=Current?Liabilities/Current?Assets Liquidity?Ratio=€4,000,000€/2,500,000=1.6

Interpretation:

• Liquidity Ratio of 1.6 indicates that KARAVAS AE has €1.6 in current assets for every €1 in current liabilities.
• Goal: Maintain or improve the liquidity ratio to ensure financial stability.

Budget Variance Analysis

Initial Budget vs Actual Expenses:

• Budgeted Expenses for Q1: €1,500,000
• Actual Expenses for Q1: €1,800,000

Calculation:

Budget?Variance=Actual?Expenses?Budgeted?Expenses

Budget?Variance=€1,800,000?€1,500,000=€300,000

Interpretation:

• Budget Variance of €300,000 indicates overspending.
• Action Plan: Identify areas with overspending and implement cost-saving measures.

Conclusion

This project provides a comprehensive roadmap to develop an expense management system for SMEs like KARAVAS AE, using a hybrid agile framework. By incorporating ratio analysis and efficient budget management, the system helps in better financial control and decision-making capabilities.
