Market share is gained by leaders, not followers. This means lawyers must be innovative and proactive. It's not enough to wait for clients to implement new processes, or demand new pricing alternatives. Lawyers must be a resource for their clients. For example, most insurance companies don't have the data or resources to come up with alternative billing strategies.
Law firms do.
Lawyers can propose new retainer relationships, such as flat fee arrangements, that allow the insurer more certainty and predictability. That kind of proactive behaviour leaves a very favourable impression with clients. Manufacturers and suppliers know you can't leave quality control to the individual worker. Even most professional service sectors have set up well-developed peer review systems. But few law firms or law departments have done the same.
