2 Abstract Supply chain management continues to be a key competitive factor for firms with relatively important inbound and outbound flows. This paper, based on a sample of 30 Venezuelan manufacturing firms, analyzes the logistics practices currently used by these firms. Data has been gathered thanks to the questionnaire prepared for the fourth edition of the International Manufacturing Strategy Survey, a tool that periodically surveys manufacturing firms about their manufacturing and supply chain strategies, practices and performance. This IMSS edition has focused on industrial firms manufacturing machinery, electric and electronic devices, medical and optical equipment, all kinds of vehicles and, in general, metal parts and components. We have chosen the answers to the Supply Chain Management section to try to understand how Venezuelan firms are overcoming the difficulties associated to a nonfriendly environment. Results show that logistics opportunities in Venezuela remain open as outsourcing, network integration and information technology are not yet fully used. Venezuela Fourth economy (behind Mexico, Brazil & Argentina) in Latin America, Venezuela continues to be highly dependent on the petroleum sector, accounting for roughly one-third of GDP, around 80% of export earnings, and over half of government operating revenues. However, manufacturing and oil refining industry represent about 25% of GDP, a figure rather stable for the last 20 years in spite of political and economic turbulences experimented by the country. Venezuela lays in the northern part of South America representing a key location for merchandising flow in the continent and very well placed as a pivot point vis-à-vis of commercial exchange with Europe. In order to transform these comparative advantages into competitive ones, logistics activities in Venezuela must improve a lot to match regional and international standards. However a country with huge oil resources, its road network has deteriorated in the past years, railroads and maritime transport are well below regional standards (CAF) and trucks and lorries are insufficient and highly depreciated making deliveries rather slow and unreliable. Moreover, Venezuelan economic and social variables do not favour an adequate environment for global and even local competitiveness. Rankings from IMD (2005) and WEF (2005) place Venezuela in the last places between the surveyed countries. Supply chain issues in Venezuelan industry Sample and firms profile Information analyzed in this paper was collected between March and October of year 2005 and includes 30 industrial firms ranging from small electrical transformers manufacturers to automotive assemblers. Respondents employ 325 persons in average with annual revenues of about US $ 15 million. The upstream leg Suppliers relationships Suppliers characterization From the competitiveness point of view, sourcing has become a very important issue. Our respondents consider that almost half of their suppliers are strategic ones. In average, these firms work with 58 suppliers and for each of their purchases they use six providers in average. Figure 1 shows the geographical distribution of the suppliers. More than half of them are based outside the country. As

3 regional economical integration is not yet well developed, this fact implies that nationalization processes are necessary very often generating a delay source which impacts on safety stocks, JIT processes and delivery times. Figure 1 Suppliers geographical distribution Figure 2 shows the average suppliers categorization. Not surprisingly, parts and materials represent more than 92% of the total purchases, leaving systems and soft technology standing for less than 8%. These figures suggest a certain gap in systems utilization between Venezuelan firms and WCM ones. Systems suppliers 6,96% Parts suppliers 38,26% Materials suppliers 54,79% Figure 2 Suppliers categorization Criteria to select strategic suppliers In a logistics survey carried out during 1998 and 1999, Díaz and Pérez (2000) found that quality, reliability on delivery and price were the three main reasons to select a provider in Venezuela. As it can be seen in Figure 3, our study confirms that this perception has not changed. Quality, delivery performance and lowest price were the three main criteria indicated by our respondents in a Lickert scale from 1 (non important) to 5 (very important). It is interesting to note that the criteria willingness

4 to disclose information received a very mitigated grade. Trust -a key element in modern and effective supply chains- is not a common characteristic between Venezuelan manufacturers.

These results confirm the low level of integration between suppliers and customers among the surveyed firms. Although some issues obtain a good score, physical integration and holding of materials into the plant receive a very low value. A technique as CPFR (Collaborative Planning Forecasting and Replenishment), which is playing a key role in successful supply chains, obtains also a score below average. According to our respondents, 50% of their purchases are delivered in a JIT (Just In Time) manner. But, what does it mean a JIT purchase? In Figure 5 we have crossed two results collected in the survey. For each firm we have plotted the proportion of raw materials delivered JIT versus the average number (in days) of raw materials inventory that they hold. The figure illustrates that JIT is a very relative and subjective concept. For instance, firms that hold a ten day inventory considers that its JIT indicator is nearly 100%; other firms with similar raw materials inventories claim for a very low percentage of JIT purchases.

6 Use of electronic tools with suppliers Figure 6 shows the use intensity of Internet or EDI-based technologies to exchange information with suppliers. Access to electronic catalogues and estimates inquiries are the more common uses of electronic exchange information. More sophisticated applications as data analysis and auctions on line are much less used by our respondents.

About 30% of these customers are considered strategic. Figure 7 shows the geographical distribution of the customers; it is clear from this figure that Venezuelan exports are rare and most of them are addressed to the Andean countries, where a free trade agreement is in place.

About 45% of their production is conformed by finished products delivered to the end customer either directly or through wholesalers and distributors. The other 55% are semi-elaborated products which are delivered to other manufacturing or integrator firms. End users 15,68% System integrators 3,86% Finished products manufacturers 41,31% Wholesalers / distributors 39,15% Figure 8 Type of final product supplied Coordination & planning criteria an JIT issues with clients Coordination and planning criteria between surveyed firms and their clients are similar to those developed with suppliers. Figure 9 shows that the two strategies more commonly used with clients are

8 the same used with suppliers (see Figure 4). Same behavior is observed with the less used strategies which are associated with Vendor Managed Inventory (VMI) and physical integration in plants. To be noted that according to observed values, surveyed firms consider that coordination strategies with clients are closer that those with suppliers (see average values in Figures 4 and 9).

As we did for the suppliers, Figure 10 shows the crossing of the proportion of finished goods delivered JIT versus the average number (in days) of final product inventory that they hold. We can appreciate the same phenomenon observed in the case of raw materials. The figure illustrates that JIT is a very relative and subjective concept.

Access to electronic catalogues and estimates inquiries are the more common uses of electronic exchange information. More sophisticated applications as data analysis and auctions on line are much less used by our respondents.

It is interesting to note that in any case, the future vision is more proactive that the perception of past facts. On the other hand, we find out that customers coordination is a strategy visualized as more accessible that suppliers coordination. This perception is justified by the fact that most of our respondents customers are based in Venezuela. Another interesting fact is to see that supply strategy is the aspect with less interest in both fronts: past and future. Finally, Figure 13 shows the reasons that move surveyed firms to use outsourcing in their logistics activities. It is interesting to observe that average scores are quite low (between 2.64 and 2.88) which it is a signal that there are in Venezuela huge opportunities to firms that could offer added value services in this field.
