Data collection is an integral part of the process of organization development. The data collection can bring about an element of unity among the members of the organization regarding the changes that require implementation at the organization. The methods of data collection: quantitative and qualitative are both required in specific situations and they both have their unique benefits. The qualitative methods include interviews, focus groups, observations, ethnographic participation, triads and dyads. The quantitative methods are surveys, audits, click streams and purchase transactions.
