It was led by three independent variables namely power politics, organization resources and environmental dynamics against a single dependent variable which is organization performance. It was performed with the usage of explanatory study design with the data being gathered by causal relationship approach. The data to fill the gap of the study was generation of selected case study whereas 100 respondents were used to gather information from structured questionnaires. The data collected from the field were filled in the SPSS data sheet to produce relevant statistical measurements to show the study results. In that case, descriptive statistics were first produced from the data sheet specifically percentages and the frequency distribution tables to describe the profile of the respondents; as well as the description of the each study objectives. In addition to that, correlation and multiple regression analysis were also used to describe the relationship between study variables to fill the knowledge gap of the study. Findings of the study showed that out of three predicting variables power politics is positive and significant statistically on organization performance which is the dependent variable. However, organization resources and environmental dynamics are positive with insignificant effect statistically on organization performance as the dependent variable. This is to say that organization performance through decision making in public sector organizations in Tanzania is influenced positively by power politics. This implies that organization performance in National Identification Authority (NIDA) through decision making is influenced by power politics. The study gives recommendation on importance and necessity for the government entities or public institutions to consider decision making as a corner stone for performance, productivity and managerial excellence for the attainment of good governance.
