Yes, mistakes do happen. The real question is how we deal with them. When we make a mistake, we take responsibility and we fix it - quickly, professionally, openly.
For example, a recent IESC-led agricultural credit program for the Millenium Challenge Development Authority in Ghana was at risk due to problems with field management. Our Vice President of Global Program Operations moved quickly. He flew to Ghana and led the effort to redesign the program and replace field management. After much hard work, the program exceeded its goals and is being extended through the end of Ghana's compact with MCC.
