Your consulting agency works with you, in part by evaluating and addressing your needs. After you agree to work with an agency, the agency will present you with a scope of work detailing the services they will provide and/or the consulting retainer hours.
Next, they will go through a discovery phase in order to learn all they can about your business, competitors, and specific challenges. From there, expect a detailed strategic plan with budgets, timelines, and key performance indicators.
Depending on your arrangement, the agency may leave implementation to your team, or provide you with the resources needed to initiate the plan. In either case, the agency continues to support you by analyzing and optimizing plans throughout the implementation phase.
