So-called "growth through innovation" strategies continue to drive supply chain complexity at a rapid pace, making it harder for businesses to forecast, according to the 2014 Terra Technology Forecasting Benchmark Study. Data shows that demand planning has reached a performance ceiling with forecast value-added declining for a second year.

Terra Technology has entered into a global partnership with Wipro Ltd., a provider of information technology, consulting and outsourcing services.

North American supply chains became more complex in 2012 as the economy continued to recover. Rapid innovation, higher seasonal sales and increased reliance on promotions contributed to make forecasting more challenging. These and other findings are contained in the Terra Technology Forecasting Benchmark Study, now in its fourth year.
