Learn about unstructured search methods like brainstorming and nominal group technique, plus tools like groupware and videotape analysis. Encourage idea generation and avoid groupthink. Apply structured searches with the SEARCH framework for systematic problem-solving.

Search for solutions • Unstructured search • Use group techniques: • Brainstorming • Nominal group technique • Groupware • Videotape analysis • Encourage ideas, discourage criticism • Avoid “groupthink” • Systematic structured search • Structured search using the acronym SEARCH
Brainstorming • Leader: State problem clearly • Group: Make suggestions orally • No evaluation at this point • Leader: Reword and write down ideas • Don’t worry about getting every word down • Leader: Encourage participation • Not “everyone gets a turn”, but be sure all have a chance to speak • Group: Evaluate/rank ideas • Use affinity diagrams to group into themes
Nominal group technique • Leader: state problem • Individuals: Make suggestions in turn • Be sure all have a chance for input • Leader: display ideas • Group member agrees to wording • Group: vote for best ideas • “Dot” method or ranking • Leader: tally votes • Identify clear winners • Group: discuss top ideas further
Groupware • Allows multiple computers to communicate simultaneously. • Permits nominal groups to be at different locations. • Makes information widely available. • May cause information overload.
Videotape analysis • Operations are recorded so they can be viewed later • Multiple people can interact during viewing • Operator can explain video to team (autoconfrontation) • Results of meetings may be potential solutions or indications for further analysis
Systematic structured search • Identify management’s perception of the problem • Obtain job descriptions, historical data, and management perspective • See for yourself • Walk through and observe • Use a checklist • Obtain information from the operator • Get information from the supervisor • Measure light, noise, dimension, etc.
