From Klondike to Homing The Product Development Process

Project Management Process Project Execution Project PlanningProject Preparation Project Adaptation

Generic Product Design Process What do you think about the above process? Think Not good Good Research

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 searchHoming 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 modelling Accurate CAD and prototyping

Discussion Do you think product design is a two-step process (Klondike and homing), or it has more steps? Klondike Nothing Good ResearchHoming Not good
