Pros
DAI is a leader in USAID-funded international development, has strong technical expertise, and increasingly good project management. As an employee-owned company, there is a sense of shared ownership and responsibility--and a sense that employees do have some influence over the direction of the company and the work environment. In comparison with it's largest competitor, Chemonics, DAI has a great benefits package and a good work-life balance (partly because DAI bids more selectively). I have worked at several companies and organizations in international development and DAI is where I want to stay.
Kontras
The downsides are minor, but occasionally I do find that--in the name of ongoing improvement--DAI actually makes a step backward by discarding things that work. As part of DAI's performance-based evaluation approach, there needs to be consequences when people do not perform--particularly when someone puts the company at risk.
