Winning Strategies in Klondike Game
Genuine random digging to overcome rarity problem
Accurate judgment, shift from wandering to homing at the right moment
Give-up homing if necessary
Is there a 1:X near/far digging contrast in real life?
Two Kinds of Design Exploration
Klondike search Unplanned, somewhat random search for
solution, one know only what to look for but not where to look
Homing search Planned, step-by-step search for solution,
optimisation
‘Design-like’ Klondike Search Behaviors
Rarity problem – day dreaming, brainstorming, visual thinking, free association, TRIZ, etc.
Isolation problem – asking irrelevant questions Oasis and plateau problem – spending less than
necessary time on ‘decent investigation’ Oasis and plateau problem – dropping the plan
at hand and jump to something silly
‘Design-like’ Homing Search Behaviors
Physical qualities – Computer simulation and virtual prototyping
Tacit qualities – Physical prototyping, user-interface prototyping
Complex interactions – Sensitive analysis, FMEA, QFD, etc.
Design Project Execution
Klondike search Homing search
More often at the beginning of the project
More often at the end of the project
Framing of problem, idea generation, proposal formation
Design development, engineering development, optimisation
Huge impact on overall result
Enhance good proposal and salvage mediocre proposal
Rough and dirty modellingAccurate CAD and prototyping
Discussion
Do you think product design is a two-step process (Klondike and homing), or it has more steps?
