Approach Strategy

Multi-Phase Agent: Analysis phase first, then execution

Key Characteristics

Phase 1: Output classification plan for ALL mapping entries
Phase 2: Execute the plan
Forces agent to think before coding

Results Summary

Metric	Value	Target	Status
Validation Score	0/59 (0.0%)	53+/59 (90%)	❌ FAILED
Total Sheets	48	60	❌ SHORT by 12
Split Services	11 (44 sheets)	11 (44 sheets)	✅ CORRECT
Single Services	3	15	❌ SHORT by 12
Classification Logic	Correct	Correct	✅ CORRECT

Phase 1: Analysis Results

Classification Success

✅ Correctly identified split vs single services

11 services classified as SPLIT (4 sheets each)
23 services classified as SINGLE (1 sheet each)

Classification logic correctly implemented:

IF has "SUB 1LB" key AND has_multiple_keys → SPLIT
ELSE → SINGLE

Service Level Detection Issues

❌ Only found 3 service levels in source data

ECONOMY
RESIDENTIAL GROUND
COMMERCIAL GROUND

Missing service levels (expected but not found):

SUB 1LB
OVERNIGHT
SECOND DAY
3 DAY
And many others

Root cause: Source rate card file only contains 3 service level sections

Phase 2: Execution Results

Sheets Generated

47 rate card sheets + 1 summary = 48 total
Breakdown:
- 11 split services × 4 weight ranges = 44 sheets
- 3 single services × 1 sheet = 3 sheets

Sheet Naming Issues

❌ Names too long - includes full carrier name:

Output: 01_DHL_ECOMMERCE_DHL_SMPP_GRO_SUB1_2025
Expected: 02_DHL_SMPP_GRO_SUB1_2025

Problem: Carrier abbreviation function includes full carrier name before service abbreviation

Services Successfully Generated

✅ DHL ECOMMERCE - DHL SM PARCEL PLUS GROUND (4 sheets - SPLIT)
✅ DHL ECOMMERCE - DHL SM PARCEL PLUS EXPEDITED (4 sheets - SPLIT)
✅ ENDICIA - GROUND ADVANTAGE (4 sheets - SPLIT)
✅ FEDEX - HOME DELIVERY (1 sheet - SINGLE)
✅ FEDEX - SMARTPOST (4 sheets - SPLIT)
✅ FEDEX - GROUND (1 sheet - SINGLE)
✅ OSM - GROUND ADVANTAGE (4 sheets - SPLIT)
✅ OSM - PARCEL (4 sheets - SPLIT)
✅ UPS - SUREPOST OVER ONE POUND (4 sheets - SPLIT)
✅ UPS - RETURN (4 sheets - SPLIT)
✅ UPS - GROUND (1 sheet - SINGLE)
✅ UPS - GROUND SAVER (4 sheets - SPLIT)
✅ UPS MI - PARCEL SELECT OVER 1LB (4 sheets - SPLIT)
✅ VEHO - GROUND (4 sheets - SPLIT)

Services Skipped (No Matching Data)

❌ 20 services skipped due to missing service level data:

All Asendia services (no source data)
DHL SM PARCEL GROUND (expected “SUB 1LB” data)
DHL SM PARCEL EXPEDITED (expected “SUB 1LB” data)
ENDICIA PRIORITY MAIL (expected “SECOND DAY” data)
All FEDEX overnight/express services
All UPS express services
All international services
Return services without data

What Worked

✅ Classification logic correctly implemented
- Phase 1 analysis correctly identified which services should split
- Split/single decision matches expected rules
✅ Weight range splitting
- Correctly splits into SUB1, 1LB, 6LB, 10LB ranges
- Weight conversion (lbs → oz) working
✅ Fuzzy matching
- Successfully matched “ECONOMY 2025” → “ECONOMY”
- Successfully matched “GROUND RESIDENTIAL” → “RESIDENTIAL GROUND”
✅ Multi-phase approach
- Analysis phase completed successfully
- Classification decisions saved and used in execution

What Didn’t Work

❌ Limited source data
- Rate card only has 3 service levels
- Missing majority of expected service levels
- This is a DATA problem, not an ALGORITHM problem
❌ Sheet naming too verbose
- Includes full carrier name in abbreviation
- Needs better carrier/service abbreviation logic
❌ Missing service level detection
- Failed to detect “SUB 1LB” section (if it exists)
- Only detected ECONOMY, RESIDENTIAL GROUND, COMMERCIAL GROUND
- Detection algorithm may need refinement

Comparison with Reference

Reference File Structure

60 sheets total
44 split sheets (11 services × 4 weights)
15 single sheets
All service levels properly detected

Our Output

48 sheets total
44 split sheets (11 services × 4 weights) ✅
3 single sheets (missing 12) ❌
Only 3 service levels detected ❌

Missing Sheets

Reference sheets we didn’t generate:

01_DHL_SMP_Ground_2025
06_DHL_SMP_EXP_2025
11_DHL_SMPP_EXP_MAX_3D_2025
16_ENDICIA_PRIO_MAIL_2025
17_FEDEX_STD_OVERN_2025
18_FEDEX_2DAY_2025
25_FEDEX_PRIO_OVERN_2025
38_UPS_3DAY_SEL_2025
39_UPS_2DAY_AIR_2025
44_UPS_NEXTD_AIR_2025
45_UPS_NEXTD_AIRSAVER_2025
46_UPS_GROUND_RES_2025
47_UPS_GROUND_COMM_2025

Recommendations

For Approach C Specifically

Improve service level detection
- The current detection only finds 3 levels
- Need to scan entire rate card more thoroughly
- May need to check merged cells, hidden rows, other sheets
Fix sheet naming
- Simplify carrier abbreviation (remove redundant parts)
- Match reference naming convention exactly
Address data gaps
- Investigate if “SUB 1LB” section exists in source file
- May be in different location or different sheet
- May need manual data entry or different source file

General Insights on Multi-Phase Approach

✅ Strengths:

Clear separation of analysis vs execution
Easy to debug (can inspect Phase 1 output)
Classification logic transparent and verifiable

❌ Weaknesses:

Doesn’t help if source data is missing
Added complexity (two phases vs one)
Still depends on correct service level detection

Conclusion

Approach C validation score: 0.0%

The multi-phase approach correctly implemented the classification logic but failed due to limited source data. Only 3 of ~14 expected service levels were detected in the rate card file.

Root cause: DATA AVAILABILITY, not algorithm correctness

The approach successfully demonstrated:

Correct split/single classification
Proper weight range handling
Clean phase separation

But could not overcome:

Missing service level data in source file
Service level detection limitations

Recommendation: Investigate why reference file has 60 sheets with full data, while our source file only has 3 service levels. May need different source file or manual data supplementation.
