The "Able List"
The general problem with deploying new technologies is they do not meet all the requirements of the “Able List”.
Adaptable:: A technology that is not adaptable is not likely to be embraced due to a high probability of obsolescence.
Affordable: If the greatest technology in the world is not affordable, it will not be accepted by industry. Remember, companies must make money to survive. The cost of the implementation versus the overall perceived payback is not considered justified by many.
Deployable: If one has to take a system off-line for a significant time, then the company cannot generate revenue from that system while the new technology is being integrated. Thus,whenever possible, new deployments should be done during normal maintenance with little additional out-of-service time.
Evolvable: Technologies must seamlessly integrate into existing systems and any upgrades must be easy to make. There is no flag day.
Global(able): Global scalability must be considered. All operations must be smooth and seamless and be capable of global deployment – particularly when it comes to security solutions.
Maintainable: One must easily be able to maintain a system once it is deployed.
Manageable: One must be able to easily manage a system in a cost-effective manner.
Reliable: The system must be reliable. Reliability affects safety, maintainability and cost.
Scalable: It is significantly more challenging to make systems work on a global scale than it is for small-scale deployment. Scalability is hard.
Securable: If one cannot secure the system to the scale of its intended deployment, the system is rendered useless.
