Challenges and Lessons Learned
• Principle challenges encountered during the development of Knovel Math:
– selection of appropriate content
– finding engineers with adequate skill set
– ensuring high quality
• Although foolproof QC does not exist, we are confident that our process resulted in quality product.
• Users play a very important role in testing and improving the quality of the products.
