Avantages
The development model could be great, particularly relative to other models like USAID. In theory they could have a high turnover model that was intentional and feed employees into other government agencies.
Inconvénients
Upper Management is terrible and prioritizes maintaining total control over the agency over running it well. New initiatives are announced seemingly at random based on which corporate execs they have been drinking or doing god knows what else with. The board of directors is AWOL except where they are actively prioritizing terrible and self interested strategic partnerships. Overworked DC employees have neither the bandwidth or the incentives to properly screen partner team work resulting in corruption and bad grant making. This Agency Runs On Burnout, while I was there it had 70% turnover, there are maybe 3 people left in the whole agency who understand how it was run even 5-10 years ago. Standard operating procedure is made up on the fly by people with no memory of or access to prior procedures, resulting in an agency that is incapable of learning from its mistakes or improving. None of the other problems will be resolved as long as turnover is sky high.
