Prior to any facts and numbers assemblage, pre-collection undertaking is one of the most vital steps in the process. It is often found out too late that the worth of their interview data is reduced as a outcome of poor trying of both inquiries and informants and poor elicitation techniques. After pre-collection undertaking is completely accomplished, facts and numbers assemblage in the area, if by consulting or other procedures, can be conveyed out in a organised, methodical and technical way.
A prescribed facts and numbers assemblage method is essential as it double-checks that facts and numbers accumulated is both characterised and unquestionable and that later conclusions founded on contentions embodied in the outcome are valid. The method presents both a baseline from which to assess from and in certain situations a goal on what to improve.

Data Assessment
In this article, we describe the subjective and objective assessments of data quality, and present three functional forms for developing objective data quality metrics. We present an approach that combines the subjective and objective assessments of data quality, and illustrate how it has been used in practice. Data and information are often used synonymously. In practice, managers differentiate information from data intuitively, and describe information as data that has been processed. Unless specified otherwise, this paper will use data interchangeably with information.
