Please kindly introduce the Agile Methodology

Data Analysis

• 
  The first round of the Delphi technique involves participants providing answers to the research question, which will then be ranked in future rounds. In a classic Delphi, no items should be added or removed, and the wording used by participants should be kept for round two. However, this may be difficult or not feasible depending on the number and types of responses provided, and content analysis can be used to group similar themes prior to the second round. An informal literature review can also be used to identify further items depending on the research question
  
• 
  In subsequent rounds, participants are asked to rank/respond to the analysed options from round one. Between rounds the group’s responses are analysed, summarised, and communicated back to the participants, a process called controlled feedback. This is repeated until consensus is reached, or for a planned number of rounds depending on the research question
  
• 
  Subsequent rounds are analysed to identify convergence of participant responses, and to provide controlled feedback. Central tendencies (mean, median, and mode) and levels of dispersion (standard deviation and the inter-quartile range) are often used. These results are fed back to participants in the next round, although no consistent method for reporting exists
