Advantages 

There are several potential benefits of internal consultants to those who employ them: 

• If properly managed and empowered, internal consulting groups evaluate engagement on projects in light of the corporation's strategic and tactical objectives. 

• Often, the internal consultant requires less ramp up time on a project due to familiarity with the corporation, and is able to guide a project through to implementation—-a step that would be too costly if an external consultant were used. 
• Internal relationship provides opportunities to keep certain corporate information private. 
• It is likely that the time and materials cost of internal consultants is significantly less than external consultants operating in the same capacity. 
• Internal consulting positions can be used to recruit and develop potential senior managers of the organization. 

Note: Corporations need to be conscious of and consistent with how internal consultant costs are accounted for on both a project and organizational level to evaluate cost effectiveness. 

• Internal consultants are often uniquely suited to 

1. Lead external consulting project teams, or 
2. Act as organizational subject matter experts ‘embedded’ with external consulting teams under the direction of organizational management.
