Use this catalog to maintain an inventory of all services and interfaces deployed in an integration or SOA environment. This catalog should be maintained by the the authority responsible for integration services in the organization; either the IT department or an Integration Centre of Competency.

  • The example outlined throughout this template describes the typical services and interfaces used in an order-to-cash process from purchasing through to accounts payable.
  • Expect to invest 0.5 FTEs per 10 integrations building out the inventory. This will fluctuate depending on how much documentation and information about existing interfaces is available.

If maintenance of the catalog is integrated into the production deployment process for new services and integration flows, the FTE associated with keeping the catalog current is minimal.

    I have a question - how long are these .5 FTE per 10 integrations supposed to be occupied? forever??
    Also does anyone know what is the ratio of FTE to integrations for actual support? Is there a paper available I can take to my management with this number?

      Thanks for your question. The duration of the task depends on how many existing integration services and/or interfaces you need to inventory. The notion of 0.5 Full Time Equivalents (FTEs) per 10 integrations equates to the following: in a half-day of work, or approximately 4 hours, one person should be able to inventory 10 services or interfaces. So if you have 20 integrations to inventory, that would keep one person busy for a day. 100 services/interfaces should keep 1 FTE busy for a week.

      After the services/interfaces are inventoried, it becomes a matter of maintaining the inventory which should become part of your integration team’s steady state process; i.e. once a service or interface is completed, it is added to the current inventory.
