Several of the posts above mentioned how that retention is important because new hires need time to get trained in their job, and I want to emphasize that this can have a huge impact on a project. New employees will not be nearly as efficient as experienced employees, and if there is high turnover on a project team, it will take a long time for the new team members to come up to speed and contribute to the project, which can lead to project delays. Even if they have experience working in the medical device industry, every company has their own culture and their own procedures, so there is a big learning curve even with a new hire with a lot of industry experience.
