The study found that ESCC integration is proceeding slowly, impeded primarily by a lack of standards for data integration. Advances in the Internet and related technology have, however, eliminated all but the last few barriers to ESCC. The remaining barriers are likely to fall pending acceptance of new ESCC standards such as RosettaNet. ESCC is already well established in select industries and will accelerate into other industries as standards develop. Currently, most ESCC activity is between top- and mid-tier manufacturers, but this activity will eventually spread down to third-tier small manufacturers. The study found no evidence that true integration, or the exchange of data between trading partners without retyping, is currently practical for most SJSMs. The study did find that low-integration ESCC is currently practical for SJSMs. In low-integration ESCC, manufacturers use Web portals to remotely access their trading partners’ information systems. Low-integration ESCC can be implemented at low cost and offers advantages such as positive return on investment, competitive advantage, and a head start toward advanced ESCC. At the time of the study, only a few SJSMs had attempted even low-integration ESCC. SJSMs have, however, widely adopted the Internet for static Web sites, for email, and for exchanging electronic documents, including CAD drawings. Although neither haste nor large investment are called for, the study recommends that SJSMs take measured steps toward truly integrated ESCC and concludes that skills in ESCC will be necessary for SJSMs to protect their competitive advantages within the next four to eight years.
