Major problems facing organisations are the high cost of software maintenance and lack of interoperability, coupled with the high cost of change, said Willie Appel, Gartner VP and programme director.
Physically deploying and changing software is approaching the cost and complexity of deploying and changing hardware, he added.
Appel was speaking at the Oracle service-oriented architecture (SOA) executive forum held in Rosebank yesterday.
The total cost of software, Appel explained, breaks down into 20% for initial development and 80% for maintenance. The expenditure on maintenance consists of 20% for corrective maintenance, 20% for adaptive maintenance and 60% for evolutionary maintenance.
