1. INTRODUCTION
Each manu ac u ing plan mus ind i s own unique pa h o success, based on con ingen

li le ligh on he easons why he applica ion o he same manu ac u ing p ac ices wo ks well
in some plan s, bu wo se in o he s (P im ose, 1992; Olhage , 1993; Nassimbeni, 1996).
Thus, be o e he selec ion, adap a ion (when equi ed), implemen a ion and in e connec ion o
manu ac u ing p ac ices, he e should also be a s a egic, well-concei ed plan based on he
pa icula si ua ion o he company. Wi hou i , he designed s a egy will no ha e he desi ed

con inuous imp o emen . Hence plan s should be dynamic, cons an ly d awing upon he bes
manu ac u ing p ac ices o hei possible inclusion as pa o he manu ac u ing p ocess.
Such inclusion depends on bo h he con ex o he plan (con ingency) and on he e ec ha
he in oduc ion o new p ac ices will ha e by linking hem o wha he plan is al eady doing
o is planning o do. This esul s in a syne gy o p ocesses designed o achie e a sus ainable
wo ld-class compe i i e ad an age by means o he con inuous imp o emen o he
manu ac u ing capaci y (Sch oede and Flynn, 2001).
Howe e , achie ing a sus ainable compe i i e ad an age, by means o using manu ac u ing
p ac ices, is i sel an e asi e goal: wo ld class plan s may some imes ha e ela i ely poo
implemen a ion le els o p ac ices. In such cases, i may well be ha he success o he plan
will quickly diminish when he condi ions change, as he solid ounda ion o a co ec ly
connec ed ne wo k o p ac ices is no suppo ing he whole. Likewise, he e may be cases
whe e plan s ha e implemen ed a high le el o p ac ices and s ill be unsuccess ul. In he la e
case, he plan s need o conside whe he hey ha e chosen he co ec p ac ices o hei own

wi h one ano he (Sch oede and Flynn, 2001). On he o he hand, he e ec i e use o
echnological esou ces—amongs o he hings—is essen ial o achie ing a sus ainable
compe i i e ad an age and o inc easing he e ec i eness o he company. The e o e, aking
in o accoun he impo ance o MS and echnology, as well as he p oposi ion ha he lack o
success in some plan s may be pa ially due o a aul y link be ween p ac ices (Sch oede and
Flynn, 2001), he p esen s udy examines he link be ween p ac ices om manu ac u ing
s a egy (MS) and om echnology om an in e na ional au o supplie sec o su ey. The
4
need o in es iga e he in e connec ion be ween s a egy and echnology has also been
s essed by Po e (1983, 1985).
Acco dingly, he p esen pape is p ima ily cen ed on he ollowing esea ch ques ion: A e

This is answe ed by way o explo a o y and con i ma o y esea ch.

2. LITERATURE REVIEW
In ela ion o he MS- echnology ela ionships, some au ho s (Ho e and Schendel, 1978;
Po e , 1983; Hayes, 1985; Maidique and Pa ch, 1988; Pa hasa hy and Se hi, 1993; Pa ke ,
2000) p esen a mainly s a ic and unidi ec ional pe spec i e. In his pe spec i e, he causal
ela ionship goes om echnology o s a egy and no ice e sa (since he exis ing echnical
capabili ies should guide he o mula ion o s a egy). Acco ding o his pe spec i e,
compe i i eness in a company’s manu ac u ing echnology is a sp ingboa d o he
de elopmen o s a egy (Pa hasa hy and Se hi, 1993). The e o e, manu ac u ing s a egy
should e lec manu ac u ing capaci ies, including echnological ini ia i es. This a gumen o
complemen a i ies implies ha plan s which y o achie e high e ec i eness om
echnological p ac ices should implemen hese in conjunc ion wi h he app op ia e
manu ac u ing s a egy (e.g. Co be and Van Wassenho e, 1993; Pa hasa hy and Se hi,
1993). Technology is he e o e a ac o ha limi s s a egy in wo ways: 1) he exis ing
5
echnology de e mines he s a egy ha an o ganisa ion can pu sue (I ami and Numagami,
1992), and 2) he company, wan ing o pu sue a di e en s a egy, should expand o change
i s echnological base (Ho e and Schendel, 1978; Maidique and Pa ch, 1988; Pa ke , 2000;
Po e , 1983).
Taking he opposi e iew, o he esea che s (Skinne , 1969; S obaugh and Telesio, 1983;
Dean and Snell, 1996) uphold ha s a egy should de e mine he selec ion o echnology.
Acco ding o his pe spec i e, o an o ganisa ion o be compe i i e, s a egy mus d i e
echnological de elopmen (Po e , 1983). In his way, echnological de elopmen can b ing
bo h a g oup o compe i i e weapons and a deepe echnological base applicable o o he
p oduc s/ma ke s o he plan (I ami and Numagami, 1992; Zah a and Co in, 1993). The
accumula ed esou ces o pas p oduc s/ma ke s may change in o he d i ing o ces behind he
di e si ica ion s a egy o he plan . The ue sou ces o compe i i e ad an age may be
de i ed mo e om consolida ing echnologies wi h manu ac u ing skills in he co e a eas o
compe i ion han om gene a ing p oduc s ha he compe i ion does no an icipa e (see
Chandle , 1962; P ahalad and Hamel, 1990). Thus, he mos impo an plan decisions in
manu ac u ing should be made o imp o e he chosen base o compe i i e ad an age (Hayes
e al., 1988; Ga in, 1993). Manu ac u ing echnology can clea ly be one o hese, since i is a
signi ican elemen in manu ac u ing (Leong e al., 1990; Ma ucheck e al., 1990). Hence, in
o de o use s a egy e ec i ely, echnology should be conside ed h ough i s lens.
Howe e , he p esen s udy will go beyond he limi a ions o any single app oach ega ding
he di ec ions o he ela ionships be ween manu ac u ing s a egy and echnology ha can be
explo ed.

Thus, he esea ch ques ion o his pape could be nuanced as o how o iden i y he MS

ela ionships.
Among he possible models o analyse hese ela ionships, selec ion i

has been chosen since
i has p o en o be he bes way o examine how a iables in e ac o explain each o he ’s
designs/implemen a ions (Ge din and G e e, 2004). Addi ionally, selec ion is he mos
common and simples o m o i in he li e a u e (Bu ns and S alke , 1961; Mo se, 1977;
D azin and Van de Ven, 1985; Galunic and Eisenha d , 1994; Meilich, 2006). Fo his,
explo a o y and con i ma o y esea ch based on h ee ela ionships, namely a bidi ec ional
and wo unidi ec ional iews o selec ion (also e med cong uency) will be used. The
adjus men p emise ha is assumed in selec ion is a cong uency be ween bo h p ac ice se s
mu ually in luencing each o he while ope a ing in a plan (see Hannan and F eeman, 1977;
Ald ich, 1979; McKel ey, 1982; Van de Ven and D azin, 1985; D azin and Van de Ven,
1985).
A close look a he way he MS- echnology ela ionships ha e been esea ched e eals ha
only nine s udies om o e 110 pape s compiled in a book edi ed by Sch oede and Flynn
(2001), whose wo main High Pe o mance Manu ac u ing (HPM) esea ch ounda ions we e

al., 1995; Mo i a and Flynn, 1997; Ahmad, 1998; Mo i a e al., 1999; Cua, 2000).
Fu he mo e, Mo i a and Flynn’s pape (1997) is he only s udy o hese nine ha is di ec ly

au ho s do conclude, howe e , ha he e is an impo an link be ween his echnological

Since said book, only h ee wo ks in his same line o HPM esea ch ha e di ec ly examined

only echnological a iable.
Rega ding he gene al P oduc ion and Ope a ions Managemen (POM) li e a u e, mos o he
p e ious s udies ha e explo ed he ela ionship be ween business s a egy (no MS) and
echnology, ei he in a one-dimensional o a mul idimensional way. Some esea che s ha e
classi ied he essen ial dimensions/p ac ices o echnology ha a e inhe en in a speci ic

This li e a u e shows some empi ical in e connec ions be ween speci ic dimensions/p ac ices

Be ge on, 2001).
Thus, some o hese s udies ha e indeed p oposed in eg a ed models ha desc ibe i s

Pa ch, 1988; Zah a and Co in, 1993). Howe e , hey ha e no empi ically shown i he e is a

In conclusion, al hough he abo e s udies ha e inc eased he gene al unde s anding o

Due o he abo e, i is no clea whe he he ela ionship be ween MS and echnology is

All o he measu emen s used in his s udy we e pe o med using pe cep ual scales, each

4.3.1. Co ela ion
The ypical es ing scheme associa ed wi h he selec ion app oach is he assessmen o simple
co ela ion be ween each pai o MP a iables (e.g. Aiken and Hage, 1968; Cohn and Tu yn, 1980;

Hypo hesis H1 equi es he s eng h o he ela ionship be ween wo se s o a iables o be es ed.
Canonical co ela ion analysis is used o es his ela ionship. I cons uc s a weigh ed linea

Th ee c i e ia we e conside ed o assess he s eng h o he o e all ela ionship desc ibed by canonical

Fo he signi ican canonical pai s, canonical c oss-loadings a e calcula ed as he co ela ion be ween

Na u ally, canonical co ela ion analysis is easible i you do no wan o conside one se o a iables

4.3.2. Reg ession
The e migh be some limi a ions o he use o canonical co ela ion analysis o es ing he p oposed
hypo heses. The main basis o his is ha he conside a ion o a iables om he wo domains in

Mackey, 1992; Hai e al., 1998). This analysis no only shows he gene al di ec ion o he associa ion,
bu also de e mines he deg ee o which he independen a iables a ec he dependen a iables.
He e, as opposed o ea ing he a iables as independen pai s, se s o a iables om he wo domains

o eg ession is used when you ha e wo o mo e a iables ha a e o be p edic ed om wo o mo e

MS (H2), and secondly MS om T (H3). In bo h cases, his pape uses hei speci ic p ac ices.
This eg ession is "mul i a ia e" because he e a e h ee ou come a iables (scales o p ac ices) om
one o he MP se s. I is a "mul iple" eg ession because he e a e h ee p edic o a iables (scales o

simul aneous equa ions, because i may cause he eg ession coe icien s o be biased. The e o e each

19
MMRA is a logical ex ension o he mul iple eg ession concep o allow o mul iple esponse

The selec ion pe spec i e is suppo ed by he s a is ical signi icance o β associa ed wi h he

Thus, o he i s MMRA wi h MS as a p edic o , mul i a ia e es s gi e he ollowing o he

Hence, o he i s s age o he i s eg ession, all MS p ac ices a e signi ican o po en ially

Table 2b shows he esul s o he i s model (equa ion 1) in mo e de ail. The columns

p obably due o some ype o es ic ion caused by planning. MMRA showed ha bo h MS1

MMRA calcula ions showed ha all MSs ha e posi i e impac s (βs a e 0.309, 0.169 and

Thus, hese esul s show ha all o he MS a iables (excep MS2, which is pa ial) in he
