Carline also identified as key challenges the company's "speed to market" ability and finding technology that "scales more readily".

"We're very likely to standardize," Carline said when asked about the future of Baycorp's numerous platforms.

"We are committed to a single platform on a trans-Tasman level [and] the investment we have in pSeries was made in the past two years, so we are looking to leverage that."

Baycorp is investigating the feasibility of re-hosting its mainframe and iSeries applications on the pSeries. Also on Carline's radar is moving away from iSeries application development to Java and .Net.

"The main issue is consolidation of outsourced vendors and a little more outsourcing of infrastructure," he said, adding that the decision to go with IBM or CSC will be made in the next few months.
