Work in Process / in planning • Further investigation of the SC geographic dispersion–performance –relationship: e.g. the increase in explanatory power by incorporating friction into the dispersion measure, and the role of moderating variables: • Logistics significance • Performance monitoring • Internal integration • External integration • Information systems • Determinants of SCM capability priorities: • Independents: SC geographic dispersion, firm size, sector, manufacturing strategy, SC echelon, logistics significance, relative performance • Dependents: 12 SCM competence areas

Personal development goals in research: • Aim for less articles with the word ”Russia” in the title • Aim for emphasis change from descriptive to normative • Aim for more research with modelling approach: • system dynamics, strategic business/SC models • discrete event simulation

BACKGROUND: Implications of internationalisation and global footprint on supply chains? Source: World Bank (2007 and 2010) Source: Geringer, Beamish & daCosta (1989)
The research question: How does geographic dispersion of the firm’s supply chain impact supply chain performance at the firm level? Construct no. 1 Construct no. 2
Research data • Sub sample from the State of Logistics Finland 2009 – survey • 109 large manufacturing companies operating in Finland (annual turnover over 50 million EUR) • Sample covers over 80% of the total turnover of the Finnish manufacturing industry
Construct No. 1: SC geographic dispersion Stock et al. (2000) The geographic dispersion measures range between zero and unity, the former meaning the network is concentrated completely in one region, and the latter implying an evenly spread network in all six regions.
How did we measure SC geographic dispersion? Based on Stock et al. (2000)
Construct No. 2: SC performance Based on e.g. Töyli et al. (2008), Gunasekaran et al. (2001), Stewart (1995)
Is there a relationship? Expected effects (hypotheses) Based on e.g. Maister (1976), Prater et al. (2001), Chopra (2003), Choi & Krause (2006)…
Method selection Previous research has also shown the tendency of cost variables to high skewness and to cause complications in standard statistical analysis, such as in the OLS regression analysis (Dodd et al., 2006). We use generalised linear models (gamma as random component, and log as the link function) to investigate the relationships between independent and dependent variables, supported by Dodd et al. 2006 (except with CCC: normal distribution with identity as the link function)
Expected and observed effects of SC geographic dispersion on SC performance Shaded cells indicate hypotheses that can neither be confirmed nor rejected due to the lack of statistically significant results, white cells indicate results with statistically significant results at minimum 0.1 level, while * implies significance at 0.05 level and ** significance at 0.01 level. Signs + or – indicate the direction of the expected and observed relationships (expected/observed).
Performance effects of unit increases in geographic dispersion variables
Concluding remarks • Signs of the statistically significant relationships are as hypothesised • This research provides explicit evidence on the dispersion-performance relationship • Of the three geographic dispersion dimensions, purchasing and sales seem to have equally notable effect on firm level supply chain performance • Production dispersion is the only independent that may balance detrimental performance effects with an improved level of service performance
Implications • In internationalising and global companies, the management of supply chain performance should be high on the agenda, especially in terms of logistics costs and cash-to-cash cycle time. • Managers should be acutely aware of the possibly major performance implications of geographically dispersing supply chains, for example in the context of internationalisation of sales, and aim, when feasible, for consolidation in for example the supply base. • Such development aims should naturally be balanced with the drive to geographically diversify sourcing as a risk management strategy. • In this context, our research sheds light on the possible cost effects of the diversification strategy.
