Idea driven analysis tools
- affinity diagrams
- categorize information by sorting concepts into categories
- used when facts/thinking uncertain or unorganized
- steps to create
- brainstorm
- verbalize every possible idea or requirement
- write each idea on a note card and place in random location on work space
- grouping
- done in silence
- each person groups items into nodes of no more than seven items
- if needed, create duplicates of items to show them in multiple nodes
- titling
- talking allowed
- create header/title card for each node
- nominal group technique (NGT)
- identify and rank key issues
- balance participants, gives everyone equal voice
- consensus building tool
- initial ideas generated individually
- steps
- introduction given
- individuals list their responses silently
- responses written on flip chart without discussion
- each item discussed then scored individually
- advantages
- concrete orientation
- structured approach
- reduced conformity pressure as result of individual scoring
- disadvantages
- scheduling group can be difficult
- reliant on writing skills
- difficult to rate items in the future
- works best for 7-9 people, no more than 11
- matrix diagram
- shows relationships between groups of information
- used to compare efficiency and effectiveness of alternatives
- useful when several factors interact in complex ways
- typically laid out in two dimensions, requirement and process
- impact of each process or requirement is assigned
- e.g.,
Example of a Matrix Diagram
- prioritization matrices
- applies weights to help decide relative importance of items
- clarifies importance of individual factors
- assign numeric value to items based on some criteria
- similar to standard matrix diagram, but replacing numbers for text and add a total column
- highest total gets highest priority
- statistical analysis
- includes numerical analysis and extrapolation of ideas from the data
