Planning an Enterprise System Integration

A clear plan of attack can lead to smooth security design and implementation

Phase III: Implementation
The last phase is the implementation of the systems and their integration. Planning the installation steps is very important regardless of size of the construction site. For example, before a card reader can be mounted on the wall next to a door, studs are installed, then rough-in electrical (backbox and stub-up conduit), followed by drywall, taping, spackling and painting.

The larger the system and the more complex the integration, the more planning is required for the commissioning and testing tasks. Items to include on the list are credential provisioning, interactions between systems, redundancy and failure mode (power and communications) testing, and as-built documentation.

Project planning tools, such as Microsoft Project, are invaluable in forcing the project manager to consider all of the tasks that are needed to be performed and the order, duration and interrelationship of each. Smooth and problem-free design and implementation happens with effective, thoughtful planning.
