A study has found that almost two-thirds of large organisations are running far more applications than they actually need. Only four percent of those surveyed considered all their applications to be ‘business-critical’. So how do you know when it is time for an application to retire?


“Every organisation should be constantly measuring the cost of ownership for all their software systems,” commented Kareem Tawansi, CEO of software development provider, Solentive Software.

“To measure this, organisations need to consider the cost of maintaining the software as well as any supporting hardware associated with it. They will need to also measure the cost of forcing a business to match its processes to the way the aging software works. These costs should then be measured against the cost of either replacing the system, or retiring it and changing processes.

“Once these costs are evaluated, a decision can be made as to whether it is time to retire the application.

“If an organisation decides that it is time to move on, the new system and processes should be integrated with existing systems before the legacy application is retired,” advised Kareem.
