The consulting company proposes a three-part strategy to determine information requirements for a new system for MCMDU:
1. Analyze artifacts like past documents and procedures to understand past issues and organizational needs.
2. Observe current operations and employee tasks to examine processes and inefficiencies.
3. Conduct interviews with inventory, sales, and retailer staff to understand perspectives and information needs.
This approach combines document review, observation, and stakeholder input to comprehensively define requirements.
