We will do them with whatever technology is at hand because they are essential to running our organizations. Each of the four elements contributes a unique piece to the EIM process and should be treated as modular components of a complete system. A common analogy is how we buy and upgrade stereo equipment. You can buy a separate tuner, control amplifier and power amplifier, or you can buy an integrated receiver that contains all three in one box. The separates may cost more than the receiver, but since each component specializes in doing one thing very well, your system's overall performance will probably be better.
Modular components are also usually less costly to upgrade.
With a receiver, if you want to tune in, you have to replace the entire receiver. With separates, all you need to replace is the tuner. You'll pay less money for the upgrade and probably get a better product. We might upgrade stereo components every five to eight years. Software and hardware, however, are another matter.
