Mini Poll Following on from the discussion of legacy systems and platforms occurring as part of our platform optimisation workshop here, we're trying to work out the best way to avoid having your expensive IT systems degrading to legacy status. So, if you have a couple of spare minutes, let's have your views on this in our mini-poll below:

READER POLL

	A helluva lot	A significant amount	Little or none	Unsure

2. What would you say are the tell-tale signs that a system has joined the ranks of legacy?

	Primary indicator of legacy	Secondary indicator	Not an indicator
Full support no longer available from suppliers for the system or a major component of it
Skills required to maintain and support have become difficult or expensive to obtain/retain
Cost of replacement is less than the cost of supporting and maintaining when calculated over a relatively short period
Proprietary or obsolete interfaces hamper current and future integration with other systems
Knowledge of system lost with previous generations of IT staff making changes costly, risky or effectively impossible
Inflexibility undermining the ability to support critical business requirements
Spending too much time keeping it running which should be spent on newer systems that add more value

	Critical 5	4	3	2	Not at all important 1
Use the latest tools, middleware and other relevant technology
