Case studies drawn from Tanzania Breweries Company Limited (TBL) and Tanzania Electricity Supply Company (TANESCO) were chosen; representing respectively, Public Private Partnership (PPP) and Management Contract modes of privatization. The study used a Qualitative research Design adopting the Rapid Assessment Methodology (RAM).

Data were collected from TBL branches in Arusha and Dar es Salaam, while TANESCO’s branches in Arusha, Dar es Salaam, Ilala, Kinondoni and Morogoro Kidatu Hydroelectricity power generation station, were covered.
