Why emphasize concept generation early in the process

ldquoThorough exploration of alternatives early in the development process greatly reduces the likelihood that the team will stumble upon a superior concept late in the development process or that a competitor will introduce a product with dramatically better performance than the product under developmentrdquo pg 99

Concept generation answers the question of ldquohowrdquo the team will satisfy the customer needs as expressed in the functional specifications


Concept GenerationConcept Generation


bull Reduce the likelihood of costly problems later in the development process

bull Early concept generation is a very affordable way of looking at a lot of alternatives

bull Develops confidence in the team that you are not going to be surprised later on

ndashA product solution with only one alternative is not an acceptable solution--


Advantages of Early Concept GenerationAdvantages of Early Concept Generation


bullMany alternatives can be missedbullParticular concept influenced by the most

dominant person on the teambullDoesnrsquot consider product concepts from other

companies or unrelated productsbullTeam doesnrsquot get a ldquobuy inrdquo to the final proposalbullMay miss entire an entire category of solutions

bull Understanding the problem Assumptions in the team mission statement

ndash The lock will be digitalndash The lock will be lightedndash The lock will be waterproofndash The lock will be durable

Identify customer needsndash ldquoI donrsquot want to pay a lot of money for a lockrdquondash ldquoI want something that is weatherproofrdquondash ldquoI want something easy for me to open but difficult for someone to

break intordquondash ldquoI want something that looks modernrdquondash ldquoI want something that lights up for easy use in the darkrdquondash ldquoI donrsquot want to change batteries frequentlyrdquondash ldquoI want to be able to program my own combinationrdquo

bull Take the best ideas others have developed and build on thembull You donrsquot have to do everything perfectly It only takes a couple

of areas of differentiation to have a success in the market

2 External Search2 External Search


bull Avoid assuming you know more than you do about a subject bull Be careful to not over-simplify a problem

ldquoFor every complex problem there is a simple easy-to-understand wrong answerrdquo

bull Use your personal and team knowledge and creativity to generate solution concepts

bull Some guidelines for generating concepts Suspend judgment Donrsquot be quick to jump to conclusions Generate a lot of ideas Donrsquot spend time evaluating ideas just capture

them Welcome ldquoout of the boxrdquo ideas Donrsquot worry about feasibility during the

initial brainstorming Use graphical and visual methods to capture ideas Quick drawings and

sketches are great Infeasible ideas are welcome Use graphical and physical media Make analogies Wish and wonder Use related stimuli Set quantitative goals Trade ideas in a group

bullThe team should have a collection of concept fragmentsmdashsolutions to the subproblems The goal of systematic exploration is to synthesize a complete solution from the concept fragments

bullThe problem is that not all fragments will work together in a final solution space Your job is to come up with practical concepts from all the pieces

bullTools help navigating through the maze of concept fragments Concept classification tree ndash

ndash Divides the solutions into independent categories Concept combination table

ndash Helps in the selection of possible fragments Pugh Matrix -a matrix that helps determine which items or

potential solutions are more important or better than others

Concept Classification Tree



What are we trying to accomplish with the treendash Prune less promising branches quicklyndash Identify independent approaches to the problemndash Find where gaps may exist in the concept fragmentsndash Refine the thought process for a particular branch




This is a tool to link fragments into complete solutions The first step is to identify the general functional diagram for the

anticipated solutionndash For example in a simplified Innovative Directions solution

Gather data on campus locations

Format data for customer use

Provide portable copy for user

Distribute data to users

Concept Combination Table



bullStep 1- add fragments to the table

bullStep 2 is to put all concept fragments into a column of the combination table This helps to identify if concept fragments are missing or redundant

bullStep 3 is to link concept fragments into complete solutions This also shows where more evaluation or exploration is necessary

bullMany combinations are available (3 x 3 x 4 x 4)bullMany donrsquot make sense and can be quickly

eliminated bullHowever you often find a new idea by looking at

the possible combinations of concept fragments bullThis is an iterative process where you may have

to go back to square one quite often




Pugh MatrixPugh

MatrixbullPugh matrixndasha tool to facilitate the concept evaluation

and selection processbull The base-case gets a score of lsquo5rsquo for each of the

customer requirementsbull New concepts are scored relative to the base-case with a

1-5-9 approachbull Much worse than the base-case score a lsquo1rsquobull Roughly equal to the base-case score a lsquo5rsquobull Much better than the base-case score a lsquo9rsquobull Work across the matrix for each customer requirement

Important Dialog listening communication ndashunderstand team differences1048729 Consensus -do not average individual scores or matrix will fail to yield

useful info Directional tool-only much better or worse matters
