The key o deciding i a p oduc is success ul in he ma ke place is whe he o no i
mee s consume demands and p e e ences, a he han whe he he e is a
b eak h ough in echnology (Bax e , 1995). Fo mode n businesses, he eal
compe i i e ad an age lies in p o iding wha consume s a e looking o a he han
wha businesses a e good a p o iding. The explosion o p oduc a ie y may
gene a e in o ma ion o e load and lead o cus ome s who a e highly he e ogeneous
in hei willingness and abili y o in e ac wi h businesses (Miceli, Rico a &
Cos abile, 2007). Klee , T ijp and Luning (2005) men ioned ha in he ini ial
p ocess o new p oduc de elopmen , lis ening o consume s is undoub edly a key
o success. Howe e , his s ep has long been igno ed o wo ked ques ionably o
mos businesses. Ulwick (2002) no ed he o en-hea d a gumen ha asking
consume s wha hey need is useless, because hey do no know wha hey need.
Howe e , al hough hey may no be able o a icula e wha hey need,
unde s anding how consume needs a e shaped and in luenced is s ill e y
impo an in ensu ing ha po en ially used p oduc concep s a e no igno ed.
A consume has eelings owa d a p oduc because he p oduc has meaning o he
consume , and his meaning is gene a ed by cogni ion: he e alua ion as o
whe he o no a p oduc will be bough (Gu man, 1982; Zanoli & Naspe i, 2002).
The e o e, designe s no only design a p oduc , bu also he ela ed consume
cogni ion. When i comes o p oduc cogni ion, he designe ’s in e p e a ions do no
necessa ily ma ch he consume s’ desi es, and many p oduc s which a e success ul
om a designe ’s pe spec i e ha e no sold well in he ma ke place, meaning ha
he e was a gap be ween designe s’ and consume s’ cogni ion models (Chuang,
Chang & Hsu, 2001). In o he wo ds, he meaning o a p oduc o consume s is no

necessa ily he same as i s meaning o designe s. In an e a o p oduc
di e si ica ion, designe s should hus no analyze consume s’ demands and
p e e ences solely based on hei own p o essional and in e nalized hough
p ocesses.
The p oduc -cen ic app oach aces ce ain challenges o success ha can be

2.1 Consume cogni ion

selec ing, o ganizing and in e p e ing o ex e nal in o ma ion and ans o ming i
in o in e nal in o ma ion. I s main ocus is he ype o in o ma ion and he me hod
o p ocessing i . He e, in o ma ion means some hing s o ed in human memo ies,
while p ocessing me hods e e s o acqui ing, s o ing and using ha in o ma ion. In
Schi man and Kanuk (2000) de ini ion, he p ocess o cogni ion includes s imuli,
senso y ecep o s, a en ion, in e p e a ion, esponse and ecep ion. In he ea ly
phases o he cogni i e p ocess, s imuli, senso y ecep o s and a en ion a e all

eac ing immedia ely. In he la e phases, in e p e a ion, esponse and ecep ion,
he senso y sys em explains sensa ions and con e s hem o pe cep ions.
Sensa ion is a simple psychological p ocess based on physiology which can be
explo ed h ough obse a ion. In con as , pe cep ion is a complica ed
psychological p ocess which can be explo ed h ough in-dep h in e iews.
Sensa ion and pe cep ion a e a se ies o psychological ac i i ies. When consume s
decide o buy a p oduc , he in insic messages o he p oduc can be sensed

Pe cep ion hen in luences consume a i udes and beha io s. In insic messages

ones include he p ices, b ands and gua an ees.
2.2 P oduc p o o ypes
In o de o mee a ious pu poses, p o o ypes come in many o ms. Jo dan (1998)

In his s udy, p o o ype is de ined as a p oo -o -concep p o o ype, e e ing o

2.3 Empha ic design
Leona d and Raypo (1997) p oposed he empa hic design p ocess includes i e
s eps.
S ep 1: Obse a ion. Who should be obse ed, who should do he
obse ing, wha he obse e should be wa ching?
S ep 2: Cap u ing da a. Use pho og aphy o ideog aphy as ools o s o e
and con ey da a ha migh o he wise be omi ed. Empa hic design s esses
accompanying inqui y o obse e consume s, asking open-ended ques ions
like “Why a e you doing ha ?” The use ul in o ma ion ga he ed a e
sc eening will be much less han he o iginal in o ma ion.
S ep 3: Re lec ion and analysis. A e ga he ing in o ma ion in a ious

S ep 4: B ains o ming o solu ions. Inspi a ion is he mos aluable pa in

speci ically used by ans o ming obse a ions in o g aphics, and i uses

Empa hic design unde s ands consume s mainly h ough obse a ion and inqui y;
howe e , his me hod has he ollowing weaknesses (Deszca, Mun o & Noo i, 1999;

A conside able amoun o he esea che s’ ime is was ed. This is because
hey mus cla i y who should be obse ed and wha beha io should be

Rela i e o adi ional esea ch, empa hic design hus undoub edly is a
longe and mo e ime-consuming p ocess.
I has less his o y o implemen a ion han adi ional esea ch.
Theo e ically, empa hic design is easible, bu i aces some challenges
when being pu in o p ac ice. Fo example, i is no an easy ask o obse e

Mos impo an o all, hey ha e o possess he skills equi ed o analyze

In his case, o a sco e 3.60-3.80 he line is 0.75p ; o 3.81-4.00, 1.25p ; o

2.82. The “F om” alue o C( )2 is 2.39 and i s “To” alue is 3.26. The “F om”
alue o C(p)6 is 2.43 and i s “To” alue is 2.63. The “F om” alue o V3 is 3.99
and i s “To” alue is 0. The e o e, he s eng h o his chain is:
(0+2.82) + (2.39+3.26) + (2.43+2.63) + (3.99+0) = 17.52
Table 5 shows he op i e chains wi h he highes in ensi y ou o he o al o 53.

Unde aking e ec i e Basic O de ing Ideas is a key s ep in d awing Mind Maps,
