Notwithstanding your organization’s best efforts, some customers and/or projects will be lost. Surveying these businesses to understand the reasons for their departure and what, if anything, could have been done to save the relationship, can reveal valuable insight for improving your organization’s performance and products/services so that you retain and/or win future customers/projects. As well, asking for feedback shows the customer that you care about their business, which will leave a positive impression and may lead them to consider your organization in the future.
