Accountability and transparency procurement principles have played a significant role in establishing good governance in any procurement regime. These principles also safeguard the protection of human rights under human rights principles. These principles if well utilized and implemented, also encourage compliance with human rights norms. In the Tanzanian procurement regime, accountability and transparency procurement principles are also covered under procurement statutory rules. The covered principles are also articulated under regional and international procurement rules to which Tanzania is a party to them.

The author of this article believes that there is a close link between accountability and transparency procurement principles with good governance and human rights.
