UNIT02 - Lesson 7

Time-to-Close Simulation: Testing Automation

45 minutes
Lesson Overview

Lesson Focus

Full system testing and time measurement against 2-hour target

Key Unit Objectives

Enduring Understandings:

  • Automation reduces human error and increases efficiency in financial processes
  • GAAP compliance requires systematic tracking of accruals, deferrals, and adjusting entries
  • User interface design determines the usability and adoption of financial tools
  • Time savings through automation creates competitive advantage for businesses

Lesson Activities

Activity 1: Simulation Setup & Guidelines
5 minutes

Establish testing protocol and timing procedures

Details:

  • Simulation dataset: Complete month of transactions requiring adjusting/closing entries
  • Timing protocol: Start when data received, stop when post-closing trial balance complete
  • Quality standards: All entries must be GAAP-compliant and mathematically accurate
  • Teams compete against 2-hour target, not against each other
Activity 2: Full Month-End Close Simulation
30 minutes

Real-time testing of automated systems with comprehensive dataset

Details:

  • Teams receive simulation dataset: 50+ transactions requiring various adjusting entries
  • Execute complete month-end close using their automated systems
  • Record time for each phase: data input, adjusting entries, closing entries, trial balance
  • Document any errors or system failures for improvement planning
Simulation Success Criteria

Systems must deliver both speed and accuracy

  • Time target: Complete close in under 2 hours
  • Accuracy target: 100% mathematical accuracy in trial balance
  • GAAP compliance: All entries follow proper accounting principles
  • Functionality: Automation features work reliably without manual intervention
Activity 3: Results Analysis & Improvement Planning
8 minutes

Evaluate performance and identify optimization opportunities

Details:

  • Time analysis: Which phases took longest? Where can we optimize?
  • Error analysis: What mistakes occurred? How can automation prevent them?
  • System reliability: Did automation work consistently throughout the process?
  • Plan improvements for Day 8 UI and integration work
Activity 4: Peer Learning & Best Practices
2 minutes

Share successful strategies across teams

Details:

  • Teams briefly share their most effective automation techniques
  • Identify common time-savers and error-prevention strategies
  • Preview Day 8: UI design and final system integration
Required Materials
  • Comprehensive simulation dataset (50+ transactions)
  • Timing sheets and stopwatches
  • Error tracking forms
  • Results analysis templates
Differentiation Strategies

For Struggling Students

  • • Step-by-Step Macro Guides: Visual walkthroughs for macro recorder usage
  • • Pre-built Templates: Partial VBA code with clear modification instructions
  • • Simplified Scenarios: Focus on one adjusting entry type before expanding
  • • Peer Support: Pair with students strong in Excel automation skills

For Advanced Students

  • • Advanced VBA Functions: Error handling routines and user input validation
  • • Cross-Sheet Integration: Link multiple workbooks for comprehensive systems
  • • Custom Functions: Write UDF (User Defined Functions) for complex calculations
  • • Mentoring Role: Support other teams with technical troubleshooting

For English Language Learners

  • • Visual Interface Design: Use icons and graphics to supplement text instructions
  • • Technical Vocabulary Support: Accounting and Excel terms with visual definitions
  • • Collaborative Documentation: Partner with native speakers for user instruction writing
  • • Multiple Demonstration Formats: Video tutorials with visual emphasis over verbal explanation
