Acceptance Model (TAM) as the theoretical perspective prior to the emphasis on the usefulness of
the technology in the adoption. Dar es Salaam Water and Sanitation Authority (DAWASA) was
used as the area for the study from which primary data was collected in the knowledge generation
process. The data were obtained from the employees selected purposely using structured
questionnaire through the sample of 50 respondents among management staff. The collected data
were gathered and filled in the SPSS software to generate statistics useful to test reliability of data..
Descriptive statistics were used to provide the description on the profile of the respondents and
analysis of the findings. Findings indicate 72.8% of respondents are in agreement that the three
variables influence the effectiveness of accounting information system adoption. This implies that
effectiveness in the adoption of accounting information system in public agencies in Tanzania is
