What is one reason it is not advisable to continue a long-term consultant relationship without competition?

Continuing a long-term consultant relationship without competition can lead to a lack of objective assessment regarding the quality of the services provided. When an organization relies on the same designer over an extended period, it may become accustomed to their work style and outcomes, potentially leading to complacency. As a result, there may be a decreased incentive for the designer to maintain high standards or to innovate, as they don't face competitive pressures. Regular competition can encourage consultants to continuously improve their quality, adapt to new trends, and provide innovative solutions. By not regularly evaluating options, the organization might not realize if the quality of service is slipping or if there are better alternatives available in the market. Thus, diversifying consultant relationships can foster a more rigorous evaluation of quality and service.
