Common Vendor Selection Mistakes

Mistake #1: Feature-Focused Evaluation

Problem: Prioritizing feature lists over business outcomes and integration capabilities.

Solution: Focus on business value delivery and total cost of ownership.

Mistake #2: Insufficient Testing

Problem: Making decisions based on demos rather than real-world testing.

Solution: Conduct thorough POCs with actual data and use cases.

Mistake #3: Ignoring Implementation Complexity

Problem: Underestimating integration effort and change management requirements.

Solution: Include implementation complexity in evaluation criteria.
