A need to facilitate the adoption of a data quality assessment system by applying an existing system to a particular PSA generated statistics and its enabling data collection. This paper particularly intends to a) review existing data quality assurance framework prescribed locally and internationally, b) come up with a data quality assessment questionnaires for consumer price index and inflation rate through interviews with data compilers, producers, and major users, and c) recommend guide questions for use in the data quality assessment for other data systems and its enabling data collection.

Based on the results of the interviews and information from self-administered questionnaires, average scores of data compilers, data producers, and data users with respect to data quality indicators are relatively high. However, it can be noted that what is important or have high scores to compilers may not be the same for data producers.
