A market approach where only one supplier or contractor is invited to submit a bid in response to a tender. Sole-source is discouraged as a market approach unless there are specific reasons, because it does not allow for competitive tension and may create a monopolistic situation. Acceptable reasons for sole-source include:

  • Unique technology or service offering,
  • Existing relationships,
  • Compatibility with other equipment,
  • Local content obligations,
  • Genuine lack of suitable alternatives.
