Legal departments are getting bigger, in no small part due to growing legal operations staff . But despite the amount these departments spend on increasing staff levels, far more is being saved through cost-effectively bringing more work in-house. And according to research conducted by legal adviser Ari Kaplan , this trend is nowhere more prominent than in e-discovery.

Kaplan recently held conversations with 27 e-discovery decision-makers, composed of corporate counsel, legal operations staff and law firm partners, for his third annual “E-Discovery Unfiltered: A Survey of Current Trends and Candid Perspectives” report. He found that while cost and efficiency drove a significant amount of e-discovery operations in-house, there are more factors and trends at play.
