The broadcast manufacturing sector is returning to health, but supply chain problems are an inhibitor to growth, according to a recent survey by the International Association of Broadcasting Manufacturers (IABM).

Increased investment in research and development was evidence that confidence is returning, according to the bi-annual survey of senior broadcast executives, with 46% of respondents confident that market conditions will significantly improve by spring 2011.

It warned that “companies continue to be challenged by manufacturing capacity and supply chain problems that frustrate order fulfilment, and customer deferral of orders remains the largest constraint to order growth.”

A shortage of skilled technical staff was given as another barrier to growth and order fulfilment.

At the end of last month, IABM director general Peter White (pictured) told Broadcast that recession-induced changes to the way broadcasters buy kit continued to have a major impact on sales.
